Research Summary

Research in the Levy laboratory is directed at understanding the interaction of viruses and the immune system in microbial pathogenesis. It focuses on HIV infection with the goal of designing novel antiviral therapies and an effective AIDS vaccine for which both innate and adaptive responses are needed. Biologic, serologic, and molecular characterization of several HIV-1 and HIV-2 strains has revealed their extensive heterogeneity and how viruses can evolve differently in the same individual in the immune system, bowel, and the brain. A major emphasis in the laboratory has been on anti-HIV innate immune responses. The research group is evaluating the role of plasmacytoid dendritic cells (PDC), the main producers of type 1 interferons. Studies are directed at understanding how HIV-infected cells induce interferon production from PDC and what cell surface molecules, including toll-like receptors (TLR), are involved in this process. An important potent innate response we have discovered is the ability of CD8+ lymphocytes to suppress HIV replication without killing the cells. This novel CD8+ cell noncytotoxic antiviral response (CNAR) is mediated by an as yet unidentified, natural CD8+ cell antiviral factor (CAF) that blocks HIV transcription. In summary, the Levy laboratory has been conducting studies to identify CAF through RNA Seq procedures, to determine the best strategy for an AIDS vaccine and to use genetically modified stem cell approaches towards a potential HIV cure.
