BioMy research interest is to understand how human dendritic cell (DC) subsets control immunity and tolerance. Particularly, I am very interested in dissecting how this major immunological axis (i.e., the DC network) contributes to control disease development. I am also interested in developing strategies to harness this immunological axis for the rational design of treatments.

Current Research and Scholarly InterestsMy laboratory studies the strategies pathogens utilize to colonize and subvert the epithelial barrier. We have focused on the epithelial junctions as a target for bacterial pathogens, since the cell-cell junctions serve as both a barrier to infection and also a major control site for epithelial function. In particular, we are interested in how the gastric pathogen Helicobater pylori may cause cancer by interfering with cell signaling at the epithelial junctions. We are also studying how various bacteria cross and invade the epithelium. For example, we recently found that Listeria monocytogenes targets a specialized subset of cell-cell junctions at the tip of the intestinal villi to find its receptor for invasion. We are interested in determining whether this mode of gastrointestinal invasion of the epithelium is also used by other gastrointestinal pathogens.

Current Research and Scholarly InterestsOur laboratory investigates the pathogenesis of varicella zoster virus (VZV) infection, focusing on the functional roles of particular viral gene products in pathogenesis and virus-cell interactions in differentiated human cells in humans and in Scid-hu mouse models of VZV cell tropisms in vivo, and the immunobiology of VZV infections.
