"How a Single Gene Changed History: Retracing the Evolution of Pneumonic Plague."
Dr. Wyndham Lathem
“The adaptation of bacterial pathogens to new hosts and specific microenvironments within the body typically occurs via the combined gain and/or loss of genetic elements during the evolution of the species. Yersinia pestis, responsible for the devastating respiratory infection known as pneumonic plague, is a recently evolved clone of the gastrointestinal pathogen
Y. pseudotuberculosis, and represents one of the best models to examine the emergence of new virulence traits and mechanisms of disease. In this presentation, I will discuss our recent studies to identify the specific genetic changes that endowed Y. pestis with the ability to infect the lungs as it evolved from Y. pseudotuberculosis over the past 5,00010,000 years. In addition, I will describe how the acquisition of a single gene encoding the outer membrane Pla protease enabled Y. pestis to coopt host fibrinolysis factor plasminogen to cause pneumonic plague, and the surprising role of plasminogen as a “danger signal” to trigger the immune response during infection.”

"What indicates clinical outcome in nonketotic hyperglycinemia?"
Dr. Johan Van Hove
“Nonketotic hyperglycinemia is a rare genetic neruometabolic disorder that is caused by deficient activity of the glycine cleavage enzyme. Most children present in the neonatal period with hypotonia, transient apnea, coma and seizures. They go on to develop spasticity, therapy resistant seizures, and complete lack of neurological development. Yet, there are children with this condition, that make substantial developmental progress, have no or easily treatable seizures. In this presentation we will review what distinguishes these different outcomes and how this information can be used for development of treatment.”

"Understanding Biological Function in Times of High Throughput and Low Output."
Dr. Iddo Friedberg
“High throughput biological assays are providing us with a wealth of data. However, sifting through these data to extract meaningful biological information is the challenge of early 21st Century biomedicine. The gap between the data that we have, and the useful information we extract from it is growing exponentially. I will discuss two aspects of this problem.
The first problem is that of assigning a function to a gene or a gene product. In many cases, homology searches do not yield an accurate answer, or any answer at all. For that reason, computational biologists have developed methods that consider many other attributes in the sequence's data and metadata. At the same time, it is hard to decipher which methods perform better, what “better” is, and the suitability of methods to given task: that is the second problem. To help solve this problem, we formed a consortium of the Critical Assessment of Function Annotations, a community effort to improve prediction of function from protein sequences. I will discuss the CAFA effort, and how it serves the biomedical community at large by providing an updated picture of how well we can understand biology from sequence data.”

"Tumor Cell Survival During Detachment from the Extracellular Matrix: The Achilles Heel of Cancer Metastasis?"
Dr. Zachary T. Schafer
“Metastasis, the spread of cancer from the site of the primary tumor to distant locations in the body, is responsible for in excess of 90% of cancer deaths, yet the molecular mechanisms governing this extraordinarily complicated process remain poorly understood. It has become clear that an important barrier to metastasis is the induction of anoikis, a cell death process that is induced when epithelial cells lose attachment to the extracellular matrix (ECM). The overarching goal of my laboratory's work is to examine and characterize the biological mechanisms that permit cancer cell survival in the absence of ECM attachment. It is our hope that a better understanding of these mechanisms will reveal novel chemotherapeutic targets or approaches that may serve to compromise the survival of ECM-detached cancer cells and thus prevent tumors from successfully metastasizing.
There are currently 4 distinct, major research projects ongoing in the lab that are all aimed at achieving the aforementioned goal:
1. The role of ROS in the survival of ECM-detached cancer cells
2. Carcinoma-associated fibroblast-mediated inhibition of anoikis in breast cancer cells.
3. Tumor cell survival in inflammatory breast cancer.
4. Oncogenic signaling involved in anoikis regulation.
During this seminar, I will focus on our most recent studies that have unveiled novel mechanisms utilized by ECM-detached cancer cells to survive and will discuss how we might take advantage of this knowledge to eliminated metastatic cancer cells.”

"Manipulation of host vascular biology by the malaria parasite Plasmodium falciparum."
Dr. Daniel Goldberg
“Cerebral malaria (CM) is a disease of the vascular endothelium caused by Plasmodium falciparum. It is characterized by parasite sequestration, inflammatory cytokine production, vasoconstriction and vascular leakage. P. falciparum produces and exports several hundred proteins into its host erythrocyte. We are interested in establishing the function of these effectors.
One such protein is histidine-rich protein II (HRPII). Plasma HRPII accumulates in the blood of patients with falciparum malaria and is a diagnostic and prognostic marker. Using a human cerebral microvascular endothelial blood-brain barrier (BBB) model, we have found that HRPII activates the inflammasome, resulting in decreased integrity of tight junctions and increased permeability. Intravenous administration of HRPII induces vascular leakage in the brains of mice, tight junction protein redistribution and increased early mortality from P. berghei experimental cerebral malaria. We propose that HRPII is a virulence factor that contributes to cerebral malaria by compromising BBB integrity.
Erythrocytes are storage reservoirs for epoxide-containing lipid signaling molecules, including epoxyeicosatrienoic acids (EETs) and epoxyoctadecenoic acids (EpOMEs). EETs/EpOMEs function as vasodilators and anti-inflammatory modulators in the blood stream. These bioactive epoxides are hydrolyzed by epoxide hydrolases, converting them into inactive diols. We have identified and characterized two epoxide hydrolases (EH) of Plasmodium falciparum, PfEH1 and PfEH2. Both proteins are exported to the periphery of infected erythrocytes and both convert several EET regioisomers to the corresponding diols. Manipulation of PfEH1 or PfEH2 levels in parasites results in a significant alteration in the epoxy fatty acid content of infected erythrocyte phospholipids. P. berghei has no predicted exported EHs, but chemical inhibition of the host EH enzyme reduced the percentage of mice that developed severe, cerebral malaria, without reducing parasitemia. We hypothesize that the parasite disruption of EETs/EpOMEs leads to perturbed vascular function. Both the EHs and HRPII promote favorable conditions for binding and sequestration of infected erythrocytes to the microvascular endothelium.”

"Fighting Microbes: Discovery and Use of Peptide- Based Bacteriocins"
Dr. Shaun Lee
"Small peptides provide an untapped source of structural diversity much needed in pushing the frontiers of discovering new small molecule therapeutics. Peptides that are produced ribosomally by bacterial organisms are broadly known as bacteriocins. These bacteriocins comprise a large class of peptide families that have been shown to be effective as antibiotics, food preservatives, anti-infectives and anti-cancer therapeutics. With rapid advances in genomics and natural product discovery, we are currently seeing a tremendous 'explosion' in the identification and use of these ribosomally produced bacterial peptides for drug development.
One major family of peptide bacteriocins produced by bacteria are the TOMMs (thiazaole-oxazole containing modified microcins), exemplified by the hemolytic toxin known as Streptolysin S (SLS). SLS is produced by the significant human pathogen Group A Streptococcus, a major cause of rheumatic diseases as well as invasive outcomes such as necrotizing fasciitis. Although it has been widely held that SLS exerts its lytic activity through membrane disruption, its exact mode of action has remained unknown. We have recently demonstrated using high-resolution live cell imaging, that SLS induces a dramatic osmotic change in Red Blood Cells (RBC), leading to cell lysis. This osmotic change was characterized by SLS-mediated disruption of the major erythrocyte anion exchange protein, Band 3. Chemical inhibition of Band 3 function significantly reduced the hemolytic activity of SLS, and dramatically reduced pathology in an in vivo skin model of GAS infection. In addition to its well-recognized role as a cytolysin, recent evidence has indicated that SLS may influence host cell signal transduction at sub-lytic concentrations during the infection process. We identified key SLS-dependent host responses, including the initiation of specific cell death and inflammatory cascades such as Mitogen Activated Protein Kinase (MAPK) and Nuclear Factor kappa B (NFκB) signaling.
In addition to our research efforts on the mechanims of SLS function, my research program at the University of Notre Dame continues to study mechanisms of bacteriocin production and function in diverse microorganisms, along with their roles in influencing microbial dynamics. We have identified biochemical strategies that allow for the production of diverse artificial bacteriocin libraries in high yield. These strategies will greatly expand the chemical repertoire of existing compounds, and open significant avenues into new drug research."

"When Drug Research is Personal: A Brief History of the journey toward a medicine for Pompe Disease".
John Crowley and Dr. Hung Do
On Friday Sept 4th 2015, CRND held this season’s first Rare Disease Clinical Translational Seminar presented by John Crowley (J.D. Chairman and CEO) and Hung Do (Ph.D., Chief Scientific Officer) of Amicus Therapeutics. Amicus focuses on discovery and development of treatments for rare genetic disorders with particular interest in lysosomal storage diseases (LSD). The research is personal because after two of his children were diagnosed with Pompe, a severe muscular glycogen storage disorder, John Crowley led a biotechnology company (Novazyme) that set on course the development of an enzyme replacement therapy (ERT) for Pompe, to treat his children’s disease.
Lysosomal storage diseases are ~50 rare inherited disorders that result from defective function of lysosomes, cellular compartments that break down large molecules (like proteins, lipids and complex sugars). When mutation renders a defect in a lysosomal protein, lysosomal degradation slows down/ becomes blocked, leading to excess accumulation of large molecules and eventually to cell and tissue malfunction. In Pompe, the defect is in a lysosomal (protein) enzyme alpha-glucosidase (GAA), needed to break down glycogen and convert it into glucose. A way to treat Pompe is to deliver ‘pre-made’ GAA into the blood stream from where it can be delivered to cells and into lysosomes, to rescue the defect. But proper delivery is a complex multistep process, during which even the pre-made GAA enzyme can lose substantial structure and function and therefore potency. Therefore Amicus Therapeutics has designed small molecule ‘chaperones’ that help the pre-made GAA enzyme better retain its structure and function. The chaperones can also help to rescue endogenous mutant GAA protein in the patient. A clinical trial for chaperones combined with ERT is underway for Pompe.
We reflected on a remarkable dual partnership, with John Crowley providing the historical context and his family’s story and Dr. Hung Do presenting the recent science data on the effect of combining chaperones with enzyme replacement therapy in preclinical models. Dr. Do received his Ph.D. (in Biochemistry and Genetics) from Texas A&M University. He did post-doctoral training at Emory University. He is an expert and industry leader on both chaperone therapy and ERT. John Crowley received his JD from University of Notre Dame and MBA from Harvard University. He has received numerous accolades and recognition for his outstanding business leadership, social service and philanthropy.
To his family’s inspiring and well chronicled story, another extraordinary chapter was added this fall, when his daughter enrolled as a freshman, as the first student with Pompe Disease at Notre Dame.
Thanks to all who joined us for the CRND end of semester celebration on May 26th!
We enjoyed a fun time with food, family and friends in celebrating another great semester.
During the celebration, we recognized CRND faculty who received promotion and tenure.

CRND scientist discusses challenges for developing new malaria therapies on World Malaria Day
Dr. Kasturi Haldar co-authors a commentary in PLOS 'Speaking of Medicine' community blog
"Drugs for Malaria: Need to Overcome Resistance to Artemisinins and Eliminate All Stages of Parasites in a Wide Range of Transmission and Disease Settings
Targeting the parasite: a malarial sporozoite in an infected epithelial cell. Image credit: Frevert et al.
The second decade of the 21st century has been infused with optimism for malaria eradication. Although deadlines have been breached, it appears that the cumulative and long haul fight against malaria is yielding impactful results: reduction of malaria deaths from a staggering 1.2 million to ~ 600,000 from 2000 to 2013 provides a realistic context for elimination and eradication agendas. But the path forward is not just details. Major discoveries in basic, translational and capacity building research supported by commensurate funding are urgently needed to navigate challenges posed by dynamic and heterogeneous disease frontiers."
CRND Researchers identify molecular mechanism responsible for making malaria parasites drug-resistant
By: Stephanie Healey
University of Notre Dame researchers led an international team to identify a molecular mechanism responsible for making malaria parasites resistant to artemisinins, the leading class of antimalarial drugs.
Red blood cells infected with human malaria parasite Plasmodium falciparum at the 'ring' stage, either sensitive or resistant to artemisinins. Within parasites (orange with blue nucleus) that are sensitive, the target of artemisinins phosphatidylinositol-3-kinase (PI3K; green triangles) is bound to and regulated by Kelch13 (disk, multicolored), while in resistant parasites this regulation is disrupted.
According to the World Health Organization’s 2014 World Malaria Report, there are an estimated 198 million cases of malaria worldwide with 3.3 billion people at risk for contracting the infection. Although the impact of malaria is still significant, the statistics reflect a considerable reduction in the global malaria burden. Since 2010, disease transmission has been reduced by 30 percent and mortality due to malaria has decreased by almost half.
Artemisinins are powerful drugs that have the most rapid action of all current drugs against Plasmodium falciparum, the parasite species that causes the most dangerous form of malaria. Artemisinin combination therapies (ACTs) are now standard treatment worldwide for P. falciparum malaria. Unfortunately, resistance to artemisinin has been detected in five countries across Southeast Asia. Along the Cambodia-Thailand border, P. falciparum is now resistant to most available antimalarial drugs. Artemisinin resistance poses a serious global threat to malaria control and elimination.
“There are two phases of blood stage malaria infection. In the first phase, the ‘ring’ parasite stage circulates in the bloodstream, and in the second phase, the ‘mature’ parasite stage sequesters in the tissues of the body,” explained Kasturi Haldar, the Rev. Julius A. Nieuwland Professor of Biological Sciences and the James C. Parsons and Carrie Ann Quinn Director of the Boler-Parseghian Center for Rare and Neglected Diseases. “Artemisinins are highly effective in treating malaria quickly because they target the first ring stage. When patients take the medication, their fevers reduce quickly, and the parasite is eliminated rapidly.”
Although artemisinins have been widely used and investigated, no one fully understood how they worked or why clinical resistance has emerged. Laboratory studies showed that artemisinins were always active against the mature parasite stages that sequester in tissues, but clinicians were observing resistant infections from patients who were still in early stage of infections. In addition, previous genome wide association studies of P. falciparum identified genes associated with artemisinin resistance, but it was unknown how the genes worked. This Notre Dame-led study identified both the target of artemisinins in the clinically affected ring stages and how a gene named PfKelch13, a dominant marker used to track the parasite’s resistance, causes artemisinin resistance.
“We observed that levels of a lipid called phosphatidylinositol-3-phosphate (PI3P) were higher in artemisinin-resistant P. falciparum than artemisinin-sensitive strains,” said Alassane Mbengue, a postdoctoral associate in biological sciences and co-first author on the study. “This lipid is produced by an enzyme called PfPI3K. We found that artemisinins block this kinase from producing PI3P lipids.”
“We also discovered that the amount of the kinase present in the parasite is controlled by the gene PfKelch13,” Mbengue said. “Mutation in the gene increases the kinase levels, which in turn increases PI3P lipid levels. The higher the level of PI3P lipids present in the parasite, the greater the level of artemisinin resistance. We also studied the lipid levels in parasites without the gene mutation and observed that when PI3P lipid levels were increased artificially, the parasites still became proportionately resistant.”
“Our results are especially significant because we studied clinical parasites from Cambodia, where artemisinin resistance is highly prevalent,” explained Souvik Bhattacharjee, research assistant professor of biological sciences and co-first author of the paper. “We collaborated with researchers and clinicians in Asia, Europe and the U.S. This was true cooperation over several years at both the international and the local levels.”
Other Notre Dame collaborators on the study included Rob Stahelin at Indiana University School of Medicine-South Bend, Olaf Wiest in the Department of Chemistry and Biochemistry, theComputer Assisted Molecular Design Core, Shahir Rizk in the Department of Biological Sciences, and the Genomics and Bioinformatics Core.
When asked about the next steps for this research, Bhattacharjee said, “There are presently two options for overcoming artemisinin resistance. Working with our colleagues at Notre Dame, Eli Lilly & Co. and the Medicines for Malaria Venture, we need to find drugs that kill the parasite by blocking the function of the kinase from making the PI3P lipid or disrupting the production of the kinase itself.”
The study, “A molecular mechanism of artemisinin resistance in Plasmodium falciparum malaria,” was published online in Nature on Wednesday (April 15). This work was supported by the National Institutes of Health, the Parsons-Quinn Endowment and Notre Dame International.

Two recent papers shed light on how breast cancer cells avoid cell death
Two new papers from the lab of CRND Professor Zach Schafer, Coleman Assistant Professor of Cancer Biology at the University of Notre Dame, offer insights into how breast cancer cells avoid anoikis, which is cell death induced by detachment from the extracellular matrix (ECM).
CRND Celebrates Rare Disease Day
By: Jayme Russell
The Boler-Parseghian Center for Rare and Neglected Diseases recently held a two-day Rare Disease Symposium (February 13-14) and invited researchers, patients, families, physicians, and advocacy groups to speak about their personal experiences with rare diseases. The symposium anticipated Rare Disease Day, recognized worldwide on the last day of February.
Organized by Barbara Calhoun, nurse practitioner and outreach coordinator for the Boler-Parseghian Center, the event featured research presentations as well as discussion panels focused on patient experiences. Because there are roughly 7,000 rare diseases, diagnosis usually takes about 5-7 years and treatments are uncommon or even nonexistent. These diseases are emotionally hard to cope with, so it is important for patients and families to find others who struggle with the same illnesses for support.
Thanks to the RareND student club, the State of Indiana now proclaims February 28th, 2015 as Rare Disease Day.
THANKS to everyone that participated!

A new publication from the Schafer lab on a rare breast cancer
Congratulations to the Schafer lab for a new publication in the journal “Cell Death and Differentiation”. The work, which is supported by the Boler-Parseghian Center for Rare and Neglected Diseases, focuses on inflammatory breast cancer (IBC), a rare malignancy with poor prognosis and a high mortality rate. Because it’s rare, IBC is not often recognized early enough. Adding to that, IBC does not present itself as a typical cancer, and is often mistaken for an infection, leading to incorrect treatment. Untreated IBC eventually “metastasizes” spreading to other organs. In this new publication, the lead author Cassie Buchheit, along with members of Dr. Zachary Shafer’s lab, demonstrates a new mechanism by which the cancer cells are able to detach and invade other parts of the body. It also paves the way to develop new drugs that target this mechanism. We look forward to more publications from the Schafer lab that will continue to shed light on rare cancers and push forward the development of therapies.

The Clinical and Translational Seminar Series organized by CRND hosted a presentation by Dr. Meg Phillips on October 3rd, 2014. Dr. Phillips is a leading researcher in the field of malaria drug development. She shared the story of an emerging drug that targets a particular parasite enzyme with little toxicity to humans. During her seminar, Dr. Phillip described the unique journey of taking the process of drug discovery from a simple concept based in rational design in the test tube and following through all the way to studies in humans. This effort, which pulled in the expertise of a number of collaborators, has resulted in a promising new strategy for treating malaria, a disease that affects more than 300 million people globally and results in nearly a million deaths annually.
During her visit, Dr. Phillips met with students from the “Topics in Pathobiology” class, which is tied to the Seminar Series. Throughout the semester, the students read, present and discuss papers by the visiting speakers, and get a chance to meet with each visiting scholar over pizza.

CRND Professor Receives American Cancer Society Grant
From left to right:
Dr. Zach Schafer, Biological Sciences, has recently received a grant from the American Cancer Society to continue ongoing work in his lab on breast cancer research. Dr. Schafer is particularly interested in metastasis, a process whereby cancer cells depart from the primary tumor and spread to other parts of the body. Typically, normal cells that depart from their organs die. However, cancer cells tend to survive and spread to other organs. By studying the molecules that prevent cancer cell death and enable its spread, Dr. Schafer and his group hope to bring about the knowledge to develop new therapies that prevent the spread of cancer, which is essential to the treatment of aggressive cancers. Dr. Schafer's lab also conducts similar studies in inflammatory breast cancer, a rare and highly deadly type of breast cancer with very few treatment options.

In Remembrance of: Dr. Guillermina Estiu
It is with a heart full of sadness that we let you know Dr. Guillermina Estiu, spouse of Guillermo Ferraudi of the Rad Lab, passed away on Friday, May 9th 2014 after several months of illness.
Dr. Estiu was a research assistant professor (Chemistry and Biochemistry). CRND owes her a special debt because as founding member, she launched a highly successful computational modeling and chemistry core within the Center, which was then transitioned to a University Core on Computer Assisted Molecular Design, with Guille as Managing Director. We are grateful for her dynamic and enthusiastic support to all members of the CRND and the University at large. She had over 20 years of experience in computational chemistry, which she used to manage CRND and CAMD core operations. She will be greatly missed for her vast knowledge base, passion for chemistry and selfless personality.

Local Middle School Students Visit Notre Dame to Learn about Rare Diseases
On Thursday March 6th, a group of students from Lake Shore Middle School student council visited Notre Dame to learn about rare diseases. The students had lunch with Dean Greg Crawford (College of Science) and toured the Notre Dame campus. During their visit at CRND, Notre Dame students from the RareND club demonstrated how difficult it can be for rare disease patients to find diagnosis and expert care through an interactive game.
Dr. Md. Suhail Alam (Haldar lab) introduced the students to his research in Niemann-Pick Type C (NPC) disease, which is a neurodegenerative rare disease that affects children and teens. A discussion between the visiting students and Notre Dame researchers demonstrated how interested and enthusiastic they are about learning and raising awareness for rare diseases. They also shared their plans for a 5K fundraising marathon to benefit rare disease awareness.
CRND Welcomes New Outreach Coordinator

World Rare Disease Day Celebration 2014
Notre Dame celebrates World Rare Disease Day
Published: February 24, 2014
Author: Stephanie Healey
The Center for Rare and Neglected Diseases (CRND) and the Rare Health Exchange (RHE) celebrated World Rare Disease Day on Saturday, Feb. 15 at the Notre Dame Conference Center. World Rare Disease Day is a global event that was first launched in 2008 to raise awareness among the general public and decision-makers about rare diseases and their impact on patients’ lives.
“We began celebrating rare disease day in 2009,” said Shahir Rizk, director of external programs for the CRND and research assistant professor of biological sciences. “Last year, we tried out the public forum format and found it to be well received. It gives Notre Dame a chance to be engaged with the local community and to provide a forum for rare disease patients and families to interact with researchers, physicians and students.” The daylong symposium was dedicated in memory of Tylor White-Richardson and Riley Smith, two patients who recently passed away from Niemann-Pick Type C (NPC) disease, a rare cholesterol storage disorder that affects approximately one in 100,000 people.
Elizabeth Berry-Kravis ’79, M.D., Ph.D., professor of pediatrics, neurology, and biochemistry at Rush University Medical Center in Chicago, participated in a panel about experimental drug treatments. She works with families whose children have NPC. Berry-Kravis explained that for many years, the only option for NPC treatment was to provide supportive care to help alleviate the symptoms, but “thanks to the Parseghian Foundation, there has been a significant increase in NPC research in the last 20 years.”
Berry-Kravis was able to get approval from the FDA through the Investigative New Drug (IND) Program to provide an experimental treatment for her patients using cyclodextrin, a small molecule therapy, which is also being tested at other clinical sites. “These diseases have ups and downs so you need to look at trends over time, but we are seeing early subtle, but promising results,” said Berry-Kravis.
Several attendees shared their experiences in open forum focused on living with rare diseases. Coley Mrozcek shared his experience with X-Linked Hypophosphatemia (XLH), a disease that disrupts the assimilation of vitamin D and phosphorus in his body and causes bone malformation. His mother, three siblings, and daughter all have XLH. “It is different being a patient of XLH, and having a child with it,” Mrozcek explained. “My daughter is 12 years old. She has difficulty running because of the way her legs have formed and other children are starting to notice. A better form of treatment is a priority for me and the way the research is going is encouraging for me as a parent.”
Cindy Riemersma came with her 21 year old daughter, Jyl, who was diagnosed with Glucose Transporter Deficiency Syndrome at the age of four. Jyl was only the 15th person in the world diagnosed with the syndrome. There are now more than 250 people diagnosed worldwide, indicating the importance of diagnosis.
A major theme that emerged from the discussion was that all of the patients and families present had taken ownership of their situations and worked tirelessly to get the answers and treatments they needed because information and resources are much more limited with rare diseases. Muriel Finkel of the Amylodosis Support Groups Inc., a member of the National Organization of Rare Diseases, stressed the importance of service organizations that cater to specific rare diseases. These organizations can help connect patients to resources, such as treatment options, counseling and other patient families.
The second half of the day included a poster session and research presentations from Notre Dame students and faculty. ESTEEM students Bianca Fox and Yuan Gao described the RHE program, a collaboration of students and patient families working together to develop a database to help rare disease patients and their caregivers. Over the last five years, many families including the White-Richardson and Smith families have visited with Notre Dame students and faculty to help develop the RHE.
Four Notre Dame researchers discussed their work on various lysosomal storage diseases. Shaun Lee, assistant professor of biological sciences, and Tony Serianni, professor of chemistry and biochemistry, described their research collaboration on Sanfilippo syndrome, a disease which prohibits an enzyme from properly breaking down complex sugars. In addition to developing new therapies, their work also helps predict whether a patient will respond to two major types of treatments that are currently being developed for this disease. Md Suhail Alam, a postdoctoral associate in biological sciences who works with Kasturi Haldar, the Rev. Julius Nieuwland, C.S.C. Professor of Biological Sciences and James C. Parsons and Carrie Ann Quinn Director of the Center for Rare and Neglected Diseases, reported on the first plasma biomarker for neurodegeneration that can be used to monitor whether NPC patients on a therapy are improving in brain disease. Olaf Wiest, professor of chemistry and biochemistry, discussed how he uses powerful computers to find FDA-approved drugs that can be repurposed to treat rare diseases like NPC.
The second research session focused on rare cancers, which are often difficult to diagnose and have a poor prognosis. Başar Bilgiçer, assistant professor of chemical & biomolecular engineering and concurrent assistant professor of chemistry and biochemistry, described his work on developing nanoparticles to target multiple myeloma and Laurie Littlepage, Campbell Family Assistant Professor of Cancer Research, explained how her work is trying to compare the biology of a rare breast cancer that affects Kenyan women with cancers found in North America. In addition, Cassandra Buchheit, a graduate student in biological sciences who works with Zachary Schafer, Coleman Assistant Professor of Cancer Biology, spoke about her work with a rare inflammatory breast cancer that is often misdiagnosed as an infection.
Mike Hamerlik, CEO of WPS Health Insurance joined one of the patient family representatives to explain how new health insurance laws will impact rare disease patients. This panel was particularly informative to the families who have traditionally had few options when it comes to health insurance.
To conclude the seminar, the group completed a rare disease quiz prepared by the newly minted RareND club, which reminded the audience how much still needs to be done to raise awareness for rare diseases. They also sang a new version of the Notre Dame fight song to rally the fight against rare diseases.

CRND Releases new video on "Malaria Research"
CRND Launches a New Computational Core
The Center for Rare and Neglected Diseases announced the launching of the computer aided molecular design (CAMD) core facility. The CAMD core will be a state-of-the-art facility for computational chemistry. The core is based on a pilot project that was initiated to assist drug discovery and development in CRND. However, many groups in a variety of research areas ranging from chemistry, biochemistry, molecular, cell and environmental biology and computer sciences, both at Notre Dame and other universities also have needs for computer assisted molecular design, often in critical, and early stages of a project. Hence, the CAMD core will be a valuable resource for all to use computational approaches to study the complex interactions of small molecules in medicinal, industrial or environmental applications.
In spring 2011, the CRND launched two pilot projects to assist drug and insecticide discovery and development. The first arose as a need for computational analysis of the results from a screen of chemical libraries from Eli Lilly & Co to discover and develop new drugs against the malaria parasite. This project is in partnership with the Medicines for Malaria Venture (MMV), a virtual pharma agency based in Switzerland, supported by the Bill and Melinda Gates Foundation and multiple governments. The second project was the study of receptors known as G-protein coupled receptors (GPCRs) as insecticide targets. This work is supported by the Army to develop a new family of insecticides. It has fostered collaborations with the University of Michigan and Stanford University including the Nobel Laureate Dr. Brian Kobilka. GPCRs are crucial proteins in human health, targeted by approximately 40% of all drugs currently on the market. GPCRs have the potential to provide the same promise as targets for insecticides.
Dr. Guillermina Estiu, a research assistant professor (Chem & Biochem) will be the managing director of the CAMD core. Dr. Estiu has already been an active member of the CRND pilot projects, and she will utilize her experience of over 20 years in computational chemistry to manage the CAMD core operations.
Dr. Olaf Wiest (Chemistry and Biochemistry) and Dr. Jesus Izaguirre (Computer Science) will oversee the operations of the CAMD core facility. Both Dr. Wiest and Dr. Izaguirre were key to nucleating the pilot project within CRND. The success of the pilots as well as requests for assistance for other projects laid the groundwork for developing the core. Its launch was made possible by the support of the CRND Steering Committee and the Office of the Vice President of Research, Dr. Bob Bernhard.
Pilot funds are available for investigators who have not used computer assisted molecular design, but feel it will assist with their research. Professors Wiest, Izaguirre and Estiu will review and prioritize project requests. They can also assist with proposal writing/project development and will be available for consultation on a range of CAMD methodology.
World Rare Disease Day 2013
On Saturday February 23rd, CRND organized a daylong event to commemorate World Rare Disease Day. The event brought together Notre Dame researchers and students with physicians, patients and their families to discuss the everyday challenges and the most recent breakthroughs in managing rare diseases. The event, which is open to the public, was designed to give a voice to all the different groups involved with panels that interact with the audience. We heard from researchers and students about the new developments in drug design. We heard from patient families about the challenges of having a member with a rare disease and possible ways to address these challenges. Additionally, Dr. Carrie Quinn, MD, along with ND students, touched on some ethical questions that face physicians and patients in managing rare diseases. The event was successful in bringing together diverse groups who share the common goals of raising awareness and finding cures for rare diseases.

The New SPRING 2013 Issue of Signal - CRND 's Newsletter
The Clinical-Translational Seminar Series -Dr. Padmini Salgame
(Above, from the left) November 30, 2012. Drs. Padmini Salgame. Patricia Champion, and Shahir Rizk enjoy a moment on the quad following Dr. Salgame's seminar at Geddes Hall.
On her recent visit to the University of Notre Dame's Center for Rare and Neglected Diseases, Professor Padmini Salgame addressed students and faculty on the topic of "Intrinsic and Extrinsic Factors Regulating Host Anti-tuberculosis Defense." Dr. Salgame's seminar focused on two central stories. The first part of her lecture disclosed her lab's examination of both innate and acquired immune responses to Mycobacterium tuberculosis (MTB) and the role of T-regulatory cells. Salgame highlighted some of what is and is not known about the functioning of the tuberculosis granuloma, memory T-cells, and biosignatures associated with individual adaptive immune responses and the susceptibility to infection.
The second part of Salgame's talk looked at research on co-infections of MTB and helminthic parasites. Salgame described her investigation into the pathogenesis of both diseases in co-infection, particularly how the effects of the immune responses related to one infection effects the progression of infection in the other disease. For example, helminthic infection raises Th2 cell responses. and those in turn, have the effect of down regulating the Th1 responses that are so critical in resisting MTB infections. The timing of infections is crucial to determining the interplay between the body's immune responses to the two diseases. TB has a high prevalence in many regions where helminthic diseases are endemic, and it is critical to discover how these co-infections modulate the course and outcome of MTB infections. Salgame's current examinations of helminth infections and the actions of immune responses in impeding MTB progression, together with her work in innate and acquired immunity, are providing significant insights that will aid in the the development of vaccines and treatments for TB.
Following her seminar, the gracious Director of Graduate Medical Research for the University of Medicine and Dentistry of New Jersey warmly welcomed graduate students in Drs. Champion and Lee's class for lunch and a relaxed discussion on a variety of topics (see photo below of the students with Dr. Salgame).

The Clinical-Translational Seminar Series -Dr. Vernon Carruthers
(Above) Dr. Carruthers addressing the CRND CTSS audience. (Photo: C Stackowicz, 2012)
November 16, 2012. CRND's Director, Kasturi Haldar introduced Dr. Vernon Carruthers as "someone who knows more about the biology of cells and parasitic invasion than anyone I can think of." High praise considering that Drs. Carruthers and Haldar both share decades long careers investigating the mechanisms of parasitical infections. Carruthers and Haldar also enjoy alumnus status from The Rockefellar University, where they completed their postdoctoral work in Dr. George A.M. Cross's Laboratory of Molecular Parasitology. Carruthers was there in the early 1990's and Haldar completed in the late 1980s. Since then, each has pursued the study of the pathogenesis of a disease caused by a parasite. Carruther's identifies his protozoan parasite Toxoplasma gondii as "a cousin of the malaria parasite", which has been the focus of Haldar's investigations for many years. Both parasites are responsible for billions of infections annually, although Toxoplasma gondii creates a serious disease condition in only tiny percent of the 2 billion people who contract the infection. Generally, adults with healthy immune status manage to keep the parasite in an encysted state in the body and most of the people who become seriously ill from Toxoplasma gondii are infants or people who are immunocompromised due to another condition (e.g., HIV, organ transplant recipients, or chemotherapy patients).
Dr. Carruthers is currently a Professor in the Department of Microbiology and Immunology at the University of Michigan Medical School where his lab is focused on the study of Toxoplasma gondii as a "model" pathogen. A model pathogen is an organism that is extensively researched with the hope that discoveries about its biological functioning may also be extrapolated to understand the workings of similar organisms. According to Carruthers, the Toxoplasma gondii model works as a model for intracellular paracitism "because of its genetic and biochemical tractability, well defined cellular structure, and the availability of excellent rodent models of disease" (Carruthers Lab page).
Carruther's seminar was entitled, "Infection strategies of the highly successful neurotrophic parasite Toxoplasma gondii."
The Clinical-Translational Seminar Series -Dr. Timothy Grese
(Above, ND graduate student Stefan Freed and Dr. Timothy Grese)
November 2, 2012. Dr. Timothy Grese, Chief Scientific Officer for Lead Generation and External Innovation Discovery in Chemistry Research and Technology at Eli Lilly and Company, was welcomed to the CRND's Clinical Translational Seminar Series where he presented, "Open Innovation Drug Discovery (OIDD): A New Platform for Academic-Industrial Collaboration." The platform for collaboration discussed by Dr. Grese addressed a problem that is all too familiar to investigators in rare and neglected diseases research; the lack of financial incentives for the drug industry to invest in finding therapeutics for small or poor populations and the lack of resources available to non-profit universities to advance major projects in drug development. The new model for collaboration described by Grese can allow universities to use Lilly resources for their academic research into areas such as drug design, data analysis, and assay development.
The Clinical-Translational Seminar Series -Dr. George Dimopoulos
"Basically, no one had published on the circadian biology of the mosquito for a very long time. Finally, Dr. Dimopolous published his paper on photic inhibition of blood-feeding in Anapheles gambiae. This paper was crucial to my own research. Dr. Dimopoulos' work and generous advice to me over the years was really valuable to my project and eventual publication with Dr. Duffield."
-- Sam Rund, Ph.D. Cand. in Biology at Notre Dame
(Above: George Dimopoulos and Samuel Rund . Photo: C. Stackowicz, 2012)
October 26, 2012. Dr. George Dimopoulos presented his cutting-edge seminar for CRND to a delighted gathering of faculty and students whose research is focused in infectious diseases and global health. Dr. Dimopoulos's discoveries in vector control at Johns Hopkins Malaria Research Institute are very exciting because of their potential to use the mosquito's own immune system and gut microflora as means of attenuating its transmission of deadly diseases, namely malaria and dengue fever.
Dr. Dimopoulos began with maps. The first illustrated the gradual contraction of malaria endemic areas around the world. Dimopoulos pointed out the key role targeting the vector had played in elimination over 100 years. In the second illustration, Dimopoulos described the emerging growth pattern of dengue fever. According to Dimopoulos, his group works on understanding the processes of infection and immune response to both diseases, in projects that are distinct, but synergistically related. The synergy arises in the broadening of the overall knowledge about the biological processes comprising the mosquito's defense against pathogens, the understanding its genetic structures, and the development of specialized tools that serve a variety of purposes.
Dimopoulos' lab has made significant progress utilizing advanced gene expression analysis methods and technology to analyze the mosquito's functional genomics and characterize pathways, which regulate immune response and resistance to infection. In fact, the Dimopoulos group's project page reports "the first full genome microarrays for Anopheles gambiae, Aedes aegypti, Culex pipiens and Plasmodium berghei" were developed by his lab.
Dimopoulos' discussion of the role of mosquito's own innate immune system, which has evolved to protect it from the malaria parasites it ingests while feeding, summarized a number of experiments leading to the characterization of the "Imd pathway." This pathway plays a crucial role in mediating the mosquito's biological ability to fight off infection. The Dimopoulos Lab's success in describing the progressive immunological responses of the mosquito at the level specific genetic transcriptions is a powerful advance towards gene-based interventions. These interventions will eventually assist the mosquito in resisting infection and consequently reduce it's transmission of the disease to humans. Dimopoulos is careful to underline that the current approach his research aims at is a kind of genetic jumpstart of an existing immune response against the infection based on the mosquito's innate characteristics. The idea, according to Dimopoulos, is to "make the gene turn on earlier" in the infection response and to "not introduce something new."
A key finding of the Dimopoulos group is that specific microflora in the mosquito's gut are critical to its defense against parasitic invasion and the production of sporozoites. It is these sporozoites that infect the salivary glands of the insect and eventually find their way into new hosts when the mosquito feeds.
Visit the Dimopoulos groups project page to read about their advances in vector control research, many of which were described by Dr. Dimopoulos in his brilliantly accessible presentation. Indeed, a number of international students and researchers commented with pleasure on how easy it was to follow Dimopoulos's comprehensive and detailed exposition. In the words of Leonardo DaVinci: “Simplicity is the ultimate sophistication.”
George Dimopoulos, Ph.D., M.B.A. is a Professor in the Department of Molecular Microbiology and Immunology at Johns Hopkins University. He is also the Director of the Parasitology Core Facility and Deputy Director of the Malaria Research Institute, which are part of Hopkins' Bloomberg School of Public Health.

On October 12, 2012, Dr. Dara Frank visited the CRND and delivered a fascinating lecture on her lab's penetration of the opportunistic strategies of a pathogen, which is responsible for significant morbidity and mortality in humans and animals. Dr. Frank's seminar, "Molecular and Cellular Analyses of the Pseudomonas aeruginosa Cytotoxin, ExoU" further illuminated the work she described a 2011 paper outlining her team's discovery of the role of Ubiquitin in the toxic effects of P. aeruginosa (Anderson et al., Molecular Microbiology 82(6) 1454-1467). Graduate students of Drs. Patricia Champion and Shaun Lee had read Frank's paper in preparation for the study's principal investigator's visit. Dr. Frank is a Professor of Microbiology and Molecular Genetics at the Medical College of Wisconsin and the Director, Center for Infectious Disease Research.
Dr. Frank's research is focused on the interaction between hosts and bacterial factors involved in infections with Pseudomonas aeruginosa and Francisella tularensis. She explores the genetic regulation of exotoxin synthesis, examining the relationship between the expression of toxins (e.g., toxins injected into eukaryotic cells that compromise the innate immunity in hosts), the pathogenesis of the bacterium, and host responses.
In her seminar, Dr. Frank described the process by which the common bacterium, P. aeruginosa, carries the effector protein, ExoU, in an inactivated state where it cannot harm the bacterium. Once the bacterium infects a host cell, however, a protein in the host, Ubiquitin, activates ExoU and allows it to degrade the membrane of the host's eukaryotic cells. Commenting on Dr. Frank's seminar, Dr. Shahir Rizk praised her "very elegant experiment" for demonstrating that the host protein is indeed required for the toxic effect of this dangerous bacterial protein to take effect.
Pseudomonas aeruginosa is an opportunistic pathogen found in skin flora, as well as soil, water, and a variety of human environments. In humans and animals with compromised immunity, the bacterium may gain entry and colonize body organs with potentially fatal consequences. In medical facilities, the bacterium may be found in medical equipment or implements and have disastrous results, particularly in the case of biofilms of P. aeruginosa, which are particularly resistant to treatment with antibiotics.
Dr. Frank's lab played a leading role in the discovery and characterization of the "P. aeruginosa type III system," which mediates the delivery of toxins. Her lab continues to explore enzyme inhibitors, antibody reagents, and vaccines, which may potentially neutralize these damaging toxins.

|(Above) Dr. Carole Long, Chief of the NiAID/NIH Laboratory of Malaria and Vector Research's Malaria Immunology Section and Director of the PATH Malaria Vaccine Initiative Growth Inhibition Assay-Reference Center. (Photo: C Stackowicz, 2012)|
October 5, 2012. Dr. Long's seminar to CRND faculty and students entitled, "Progress toward development of a malaria vaccine" provided a comprehensive overview of the current status of vaccine development for various stages of malaria infection. Her presentation reviewed considerations for evaluating new vaccine targets and engaged the audience in an intriguing reflection on what is already known about the acquisition of immunity in endemic areas.
Dr. Long applauded the recent progress in vaccine development due to an expansion of funding and new technologies that have accelerated research. Dr. Long cited the significant advance represented in 2011 with the publication of "First results of phase 3 trial of RTS,S/AS01 malaria vaccine in African children" by Agnandji et al. (NEJM 365(20); 1863). This publication by a group from the Albert Schweitzer Hospital in Lambarene, Gabon, reports on an ongoing phase 3 study of over 15,000 children in seven African countries with respect to the malaria vaccine RTS,S/AS01. Dr. Long is the director of the PATH Malaria Vaccine Initiative, which together with GlaxoSmithKline Biologicals, is funding this research. Agnandji et al. conclude in their NEJM article: "The RTS,S/AS01 vaccine provided protection against both clinical and severe malaria in African children."
Following her presentation, Dr. Long joined ND graduate students for lunch and a lively informal discussion of her research and the extraordinary scope and achievement of the PATH Malaria Vaccine initiative.

September 21, 2012 - Dr. Jose Bufill's contribution to the CRND Clinical-Translational Semininar Series, "Preliminary observations using N-acetylcysteine for refractory TTP: An opportunity for new management strategies?" engaged both students and faculty in an exciting translational discovery underway in their own community. Dr. Bufill has been treating a patient in South Bend with refractory, relapsing thrombotic thrombocytopenic purpura (TTP), a rare disorder of the blood-coagulation system. Using N-acetylcysteine (NAC), Dr. Bufill has observed noteworthy temporary therapeutic benefits without significant side effects.
Dr. Bufill's presentation described the pathophysiology of TTP, a serious and life-threatening disorder caused by dysfunction of the normal metabolism of the Von Willibrand factor (VWF). According to the National Heart, Lung, and Blood Institute: "In TTP, blood clots form in small blood vessels throughout the body. The clots can limit or block the flow of oxygen-rich blood to the body's organs, such as the brain, kidneys, and heart. As a result, serious health problems can develop." (To read more from the NHLBI website).
TTP may be either a congenital or inherited condition and is prone to relapse since the standard therapy of plasma exchange does not remedy the underlying cause. Recently, N-acetylcysteine (NAC) has shown promise in animal models. Dr. Bufill discussed further laboratory and clinical studies projected for NAC related compounds and their potential benefits for patients with this rare disorder.
Dr. Patricia Champion Publishes in Molecular and Cellular Proteomics
September 2012 - Dr. Shahir Rizk, CRND's Director of External Programs, recently spoke to UND's Dr. Patricia Champion about her new publication in Molecular & Cellular Proteomics. Dr. Rizk describes the core finding, "identifying key features of tuberculosis infection and the development of a new method for identifying important factors that tuberculosis bacteria use to infect human cells" in the upcoming CRND newsletter, The Signal. Seed funding was provided by a CRND proteomics grant. See the abstract for Champion's innovative study below. (Left, Dr. Patricia Champion)

About The Inaugural CTSS Seminar
This fall, the CTSS seminar series was kicked off with an exciting presentation by Dr. Partick Duffy, discussing the recent progress in the fight against malaria. Dr. Duffy is a clinical researcher, whose work at the National Institutes of Health has taken him all around the world to malaria endemic areas where help is most needed. Often, such areas experience high levels of poverty and political turmoil. Most recently, Dr. Duffy found himself in the midst of a coup d’etat in Mali while training a group of students.
Dr. Duffy’s talk gave a taste of what’s to come. Several speakers are lined up throughout the semester with topics ranging from the study of infections by parasites, bacteria and viruses, to the characterization of the immune response to those infections, as well as the work carried out in developing novel therapeutic agents.

About The Center for Rare and Neglected Diseases
Science for Society
Around the globe, people are suffering and dying from diseases that have generally been ignored by major pharmaceutical companies because the potential financial rewards for developing new drugs and vaccines to treat them are insignificant. These are the rare and neglected diseases of the world. There are thousands of rare diseases, typically defined as those, which afflict less than 200,000. Among them are cystic fibrosis, thalassemia, Niemann-Pick C disease, and several of the rare forms of cancer. Neglected diseases, by contrast, can affect billions, but like their rare counterparts, have been ignored by researchers. This is especially prevalent in the developing world and in pockets of grinding poverty in developed nations, where the populations suffering from illnesses such as tuberculosis, malaria, and lymphatic filariasis do not have the money to buy drugs and vaccines, giving pharmaceutical companies little incentive to develop treatments that cost far more than could ever be recouped through reasonable prescription prices. The result is a gaping hole in healthcare—one which Notre Dame is uniquely positioned to fill.
Rare Diseases: those which afflict less than 200,000. Examples are cystic fibrosis, thalassemia, Niemann-Pick Type C Disease, adrenolekodistrophy and several forms of cancer.
Neglected Diseases: diseases of poverty, lymphatic filariasis disease pathologies of TB and Malaria.
