Antony Rosen Lab
Research in the Antony Rosen Lab investigates the mechanisms shared by the autoimmune rheumatic diseases such as lupus, myositis, rheumatoid arthritis, scleroderma and SjogrenÕs syndrome. We focus on the fate of autoantigens in target cells during various circumstances, such as viral infection, relevant immune effector pathways and exposure to ultraviolet radiation. Our recent research has sought to define the traits of autoantibodies that enable them to induce cellular or molecular dysfunction. We also work to better understand the mechanisms that form the striking connections between autoimmunity and cancer.
Kelly Metcalf Pate Lab
The Kelly Metcalf Pate Lab focuses on the role of platelets in the innate immune response to viral infection, and how modulating the response of platelets to infection alters the course of disease.
Platelets are known to participate in innate immunity through cytokine signaling and direct interactions with other cells, and the platelet has the potential to significantly influence disease outcomes. However, platelet immunology is still a relatively new discipline, and the downstream effects of platelet interactions with other immune cells have yet to be determined in the context of viral infection.
Current research in our lab aims to further characterize the platelet-monocyte interaction during acute viral infection with the goals of establishing methods of pharmacologically manipulating this association, and establishing how platelet binding to a monocyte influences the monocyte's susceptibility to lentiviral infection and the monocyte's interactions with endothelium.
Additio...nally, we are interested in the effect of physiologic stress on the platelet's future immune response to infection, and in the development and optimization of novel in vitro systems that better model in vivo conditions.
Molecular and Comparative Pathobiology
Epstein-Barr virus and Kaposi's sarcoma herpesvirus are found in association with a variety of cancers. Our laboratory studies are aimed at better defining the role(s) of the virus in the pathogenesis of these diseases and the development of strategies to prevent, diagnose or treat them. We have become particularly interested in the unfolded protein response in activation of latent viral infection. Among the notions that we are exploring is the possibility that activation of virus-encoded enzymes will allow the targeted delivery of radation. In addition, we are investigating a variety of virus-related biomarkers including viral DNA, antibody responses, and cytokine measurements that may be clinically relevant.
