Research Abstract:

We study issues at the interface between virology and immunology, working from the hypothesis that viruses manipulate the immune response using immunoevasive gene products as the immune response attempts to eradicate the virus. The resulting delicate balance determines the fate of both virus and host, and contributes to both acute and chronic disease. To understand the basis of human diseases of unknown etiology we have an active pathogen discovery program that has identified a number of novel viruses.

Three concepts drive our approach: (1) the simultaneous analysis of immune and viral mechanisms allows novel insights; (2) genetic tests in vivo are necessary to establish mechanisms; and (3) chronic virus infection has profound effects on the physiology of the host. Our experimental models involve infection of mice with a variety of DNA and RNA viruses including murine gammaherpesvirus 68 (ãHV68, MHV-68) and a virus identified through our pathogen discovery efforts: murine norovirus (MNV). Infection of mice with such viruses provides manipulable models for studying the role of viral and host genes in important disease processes.

Current projects include the: (1) cellular and molecular basis of herpesvirus latency and tumorigenesis; (2) mechanisms of interferon-ã (IFNã) and IFNáâ in control of actue and chronic infection; (3) role of autophagy in IFNã function and immunity; (4) role of viruses and autophagy proteins in intestinal immunity and barrier function in Crohn’s disease; (5) norovirus immunology, genetics, structure, and pathogenesis; and (6) pathogen discovery.
