Using modern molecular, cellular and bioimaging techniques to understand the molecular pathogenesis of disease, with particular interests in innate imume response during infection. I am interested in the way viruses evade host innate immune responses through interaction of viral proteins with cellular signal transduction pathways. The cell’s first response to viral infection is to produce interferon and cytokines to reduce viral replication and/or eliminate the infected cell by apoptosis. The central regulators that lead to production of cytokines and interferons are transcription factors, such as NF-kB and interferon response factors (IRFs). Viruses encode proteins that block these pathways, enabling them to survive and persist in the host cell. I am investigating virus-host protein interactions using
biological assays for cytokines, protein-protein interactions by pull down co-binding assays and mass spectrometry analysis, and bioimaging to recognize intracellular interactions and rearrangements.
This research will be useful to design new anti-viral drugs and make vaccines.
