Research Interests
Research in my laboratory focuses on two distinct research programs. The goals of the first program are to gain insights into prion disease pathogenesis, to develop novel assays to diagnosis prion diseases prior to the onset of clinical symptoms, and to develop an effective treatment for prion diseases. Prion diseases are fatal neurodegenerative diseases with no known cure. Increased understanding of the molecular events that lead to neurodegeneration in these diseases is needed for early diagnosis and the development of new drug therapies. We have identified hundreds of alterations in gene and protein expression that occur during the early stages of prion disease. Early changes in gene/protein expression may be important molecular events underlying prion disease pathogenesis, and these disease induced changes may serve as surrogate markers of disease and be useful for disease diagnosis as well as targets for drug therapy.  The goals of the second research program are to gain insights into human immunodeficiency virus (HIV) and simian immunodeficiency virus (SIV) pathogenesis and to help develop an effective HIV vaccine and novel therapies to treat HIV.  The HIV/SIV program is motivated by the fact that over 40 million people worldwide are infected with HIV. A pressing biomedical priority is the development of an effective HIV vaccine. Several lines of evidence have indicated that the development of an effective HIV vaccine will require the induction of a strong localized virus specific cytotoxic T lymphocyte (CTL) response.  We are using MHC-class I tetramers to stain and evaluate the localization, abundance, and phenotype of SIV and HIV specific CTLs in tissues to identify correlates of successful vaccination and to identify and characterize reservoirs where HIV/SIV accumulate and virus-specific CTL are excluded.
