Virology, immunology, and evolution; understanding the co-evolution of pathogens and human immune responses and the impact on disease development and progression
My primary research interests are to understand the determinants of virus-specific T cell responses to persistent viral infections with neurological manifestations, the co-evolution of the pathogen and the human immune response and how a better understanding of these interactions might lead to better treatment of these infections.
The main focus has been on human immunodeficiency virus type 1 (HIV-1) because the rapid evolution of this virus allows real-time evaluation of the interplay between the virus and the infected human host, but my group also works on hepatitis C virus (HCV) and human polyomavirus JC (JCV).
Neurological disturbances are frequent in patients with HIV-1 or AIDS. They occur in 30-50% of HIV-infected individuals and can present as the initial symptom, throughout the disease or in advanced AIDS.
HIV-1 might affect the nervous system directly or may act indirectly by weakening the immune system so that tumors of the nervous system or other infections develop. One example is the reactivation of JCV, which cases Progressive Multifocal Leukoencephalopathy (PML) in about 5% of untreated AIDS patients and an immune reconstitution inflammatory syndrome (IRIS) in HIV-infected patients receiving antiretroviral therapy. Because a JCV-specific T-cell response is associated with PML survival, it is necessary to understand better the determinants of these responses and how they might be reinforced.
