  • Robert Siliciano Laboratory

    Research in the Robert Siliciano Laboratory focuses on HIV and antiretroviral therapy (ART). ART consists of combinations of three drugs that inhibit specific steps in the virus life cycle. Though linked to reduced morbidity and mortality rates, ART is not curative. Through our research related to latently infected cells, we've shown that eradicating HIV-1 infection with ART alone is impossible due to the latent reservoir for HIV-1 in resting CD4+ T cells.

    Our laboratory characterized the different forms of HIV-1 that persist in patients on ART. Currently, we are searching for and evaluating drugs that target the latent reservoir. We are also developing assays that can be used to monitor the elimination of this reservoir. We are also interested in the basic pharmacodynamic principles that explain how antiretroviral drugs work. We have recently discovered why certain classes of antiretroviral drugs are so effective at inhibiting viral replication. We are using this discovery along w...ith experimental and computational approaches to develop improved therapies for HIV-1 infection and to understand and prevent drug resistance. Finally, we are studying the immunology of HIV-1 infection, and in particular, the ability of some patients to control the infection without ART. view more

  • Schneck Lab

    Effective immune responses are critical for control of a variety of infectious disease including bacterial, viral and protozoan infections as well as in protection from development of tumors. Central to the development of an effective immune response is the T lymphocyte which, as part of the adaptive immune system, is central in achieving sterilization and long lasting immunity. While the normal immune responses is tightly regulated there are also notable defects leading to pathologic diseases. Inactivity of tumor antigen-specific T cells, either by suppression or passive ignorance allows tumors to grow and eventually actively suppress the immune response. Conversely, hyperactivation of antigen-specific T cells to self antigens is the underlying basis for many autoimmune diseases including: multiple sclerosis; arthritis; and diabetes. Secondary to their central role in a wide variety of physiologic and pathophysiologic responses my lab takes a broad-based approach to studying T cell re...sponses. view more

  • Sean Leng Lab

    The Sean Leng Lab studies the biology of healthy aging. Specific projects focus on chronic inflammation in late-life decline; immunosenescence and its relationship to the basic biological and physiological changes related to aging and frailty in the human immune system; and T-cell repertoire analysis.

  • Soloski Lab

    The Soloski Lab works to understand how infection can lead to the development of chronic immune-mediated diseases. Our lab studies the role of cellular immune response in controlling infection with gram-negative bacterial pathogens, such as Salmonella typhimurium. Our work has recently focused on the role of the intestinal mucosal immune compartment in controlling oral infection. This effort has identified a new unrecognized subset of T cells residing within the epithelial barrier that expands following infection. Current efforts concentrate on understanding the recognition properties and effector function of this T cell subset and determining if an analogous population exists in the human mucosa. We also strive to understand the human host immune response to infection with Borrelia burgdorfer, the causative agent of Lyme disease.

  • The Hamad Lab

    Our research interest is crystalized into three main areas:
    1. Type-1 diabetes - Our focus is on understanding how the Fas death pathway regulates the disease and how extracted information can be used to protect high risk individuals and those with new-onset disease.
    2. Type 2 diabetes and Obesity - Our lab is studying the role of heparan sulfate proteoglycans (HSPG) in regulating body fat and glucose clearance.
    3. Double negative ??T cells - Our studies suggest a critical role for these cells in protecting kidneys from Ischemia reperfusion injury (IRI). Our current focus is understanding their origin and physiological functions.

    Research Areas: type 1 diabetes, type 2 diabetes, obesity, Double negative alpha/beta T cells, T cells
