Robert M. Blumenthal, Ph.D.
Distinguished University Professor
听
Dr. Blumenthal鈥檚 research explores two main questions. First, how do bacteria control and coordinate the expression of their thousands of genes, and how is that regulatory architecture conserved or changed between different bacterial species? His lab is particularly interested in Lrp, a widely-distributed protein that (in E. coli) controls hundreds of genes, including genes associated with virulence. Second, what is the full role of restriction-modification systems (RMSs) in controlling the flow of genes among different bacteria? Almost all bacteria have RMSs and, while they can cut incoming DNA, there is evidence that this can actually increase gene exchange (possibly including antibiotic resistance genes).
Viviana P. Ferreira, D.V.M., Ph.D.
Associate Professor
听
Dr. Ferreira鈥檚 research aims to understand the regulatory mechanisms by which humans protect their tissues from excessive, inadvertent or bystander complement-mediated damage. The complement system is a central part of our innate defense system, is an essential link between innate and adaptive immunity, and carries out critical housekeeping functions. Although tightly regulated, it also contributes to the origin of many inflammatory diseases. In order to contribute to understanding of the role of complement in inflammatory cardiovascular disease, current projects aim to define how negative regulator factor H and positive regulator properdin influence the interaction between human platelets and leukocytes.
Jyl Matson, Ph.D.
Associate Professor
听
Dr. Matson鈥檚 laboratory studies the mechanisms by which bacteria sense and respond to their extracellular environment. Vibrio cholerae causes epidemic cholera, a disease that continues to spread where people lack access to clean drinking water. Due to increasing antibiotic resistance in V. cholerae, there is a need for additional therapeutic agents. Current projects include 1) identification and characterization of small molecule inhibitors of a V. cholerae stress response pathway that may be developed into cholera) therapeutics; and 2) characterizing transcriptional responses of V. cholerae to various stresses to determine pathways associated with bacterial fitness and pathogenesis.
Tomoaki Ogino, Ph.D.
Associate Professor
听
Dr. Ogino's research interests lie in studies on gene expression of RNA viruses in higher eukaryotic cells. Especially, his laboratory focuses on understanding the molecular mechanisms of RNA biosynthesis in nonsegmented negative strand (NNS) RNA viruses. NNS RNA viruses include many life-threatening human pathogens, such as rabies, human parainfluenza, respiratory syncytial, measles, Nipah, and Ebola; however, at present there are no effective drugs against these viruses. His research goals are to define the enzymatic and regulatory roles of NNS RNA viral RNA polymerases in transcription and replication and to develop specific drugs against them.
Z. Kevin Pan, M.D., Ph.D.
Professor and Chairman
听
The main research interest of Dr. Pan's laboratory is to better understand the molecular basis of inflammatory diseases and further develop novel therapeutic strategies. In particular, his laboratory focuses on the following areas: inducible negative regulation of inflammatory responses; the host/pathogen interactions that lead to the development of several inflammatory diseases, including septic shock, rheumatoid arthritis, and airway inflammation.
Stanislaw Stepkowski, DVM, Ph.D., D.Sc.
Professor
听
Dr. Stepkowski's research focuses on the development of novel strategies: 1) to improve the survival of organ allografts, with emphasis on non-toxic immunosuppressive agents; 2) to induce permanent acceptance of allografts (transplantation tolerance); and 3) to increase survival of pancreatic islets. 听His laboratory seeks to better understand cytokine-induced T cell signaling through Janus tyrosine kinases (Jaks) and signal transducers and activators of transcription (Stats) pathways. 听Ongoing work aims to identify novel regulatory phosphotyrosine sites in Jak3, using knock-in mice with mutated Jak3 sites. 听The role of Stat3 and Stat 5a/b transcription factors are explored in Stat3 and Stat5 conditional knockouts.
R. Travis Taylor, Ph.D.
Associate Professor
听
Dr. Taylor鈥檚 research is focused on the vector-borne members of the Flaviviridae family, including West Nile virus, dengue virus and tick-borne encephalitis virus. Flaviviruses are significant human pathogens and we currently have limited treatment options. By evaluating interactions of virus and cellular proteins, Dr. Taylor has identified key host proteins that are important to antiviral responses. Understanding the molecular mechanism of host responses, as well as strategies employed by viruses to evade them, is crucial to future work in the lab aimed at developing new and effective flavivirus-specific therapies.听
R. Mark Wooten, Ph.D.
Professor
听
Dr. Wooten鈥檚 research focuses on the immune responses to bacterial infections, with primary focus on Borrelia burgdorferi (Lyme disease) and Burkholderia pseudomallei (melioidosis). His lab has developed intravital techniques using laser-confocal microscopy, that allow direct visualization of fluorescent B. burgdorferi within intact skin tissues of living mice, in order to study their interactions with fluorescent immune cell populations in real time. For B. pseudomallei, they are assessing how the pathogen prevents complement deposition and subsequent direct or opsonophagocytic killing by macrophages and neutrophils. The goals for both projects are to identify bacterial mechanisms that allow evasion of immune clearance, which may provide targets for preventative and/or curative therapies.
Randall G. Worth, Ph.D.
Professor
听
Dr. Worth's laboratory investigates the role of platelets in inflammation and infection. At a basic science level, they are identifying pathways involved in pathogen destruction by platelets. To do this, they have engineered a transgenic mouse strain capable of conditional platelet depletion. When mice are depleted of platelets, responses against infectious agents can be studied. Dr. Worth also heads a translational project directed at understanding the interacti-on between inflammation and thrombosis. Specifically, they study the role of platelets in such autoimmune diseases as Systemic Lupus Erythematosus. This project is revealing exciting new ways that platelets respond to IgG-complexes during disease.
Leah Wuescher, Ph.D.
Assistant Professor
听
Dr. Wuescher鈥檚 laboratory studies platelet-mediated effects on innate immune responses. Previous research has shown that platelets are necessary for effective immune function, and her lab has shown they are necessary for survival during respiratory infections. The Wuescher lab is investigating the molecular pathways involved in both platelet antiviral responses and platelet-mediated regulation of immune cell activities. With the increased risk of thrombosis in not only viremic infections, but respiratory infections, understanding of platelet-respiratory virus interaction will help establish novel treatments to decrease morbidity and mortality from these infections. Additionally, the laboratory has a project investigating the role of platelets in harnessing the immune system to improve the healing of hypovascularized tissues. Dr. Wuescher uses targeted mechanical and molecular approaches to examine how platelets can improve tendon remodeling after injury, aiming to improve the outcomes for patients with these types of injuries.
