Weiss Laboratory

Summary:

My lab studies coronavirus pathogenesis. We use murine coronavirus, mouse hepatitis virus (MHV) infection of mice as a model system for the study of: 1) acute viral encephalitis; 2) chronic demyelinating diseases such as Multiple Sclerosis and 3) virus-induced hepatitis. We have the important tools of a well-developed animal model system and two reverse genetic systems with which to manipulate the viral genome. Human coronaviruses are primarily respiratory viruses, and include the common cold viruses OC43 and 229E as well as the emerging viruses MERS and SARs that cause severe and life threatening diseases. We are beginning to study human coronavirus interactions with respiratory tract cells. Our long-term goal is to elucidate the viral and cellular determinants of coronavirus tropism and pathogenesis in the brain, the liver and the lung. Much of our current work focuses on coronavirus-encoded antagonists of type I interferon, specifically virus-encoded phosphodiesterase that antagonize the OAS-RNase L pathway. Another direction in our lab is the study of the role of inflammasome related cytokines in viral clearance as well as both acute and chronic MHV induced disease.
