Our laboratory is studying the molecular mechanisms of innate immune recognition by identification and analysis of receptors involved in innate immune recognition and activated signaling pathways. We are particularly interested in the recently identified family of Toll-like receptors, which play a critical role in the mounting of innate immune responses. We wish to understand the mechanisms by which TLRs recognize different pathogen associate molecular patterns (PAMPs), as well as the regulatory mechanisms of TLR signal pathways that lead to NF- k B activation. We are also interested in studying the important links between chronic infection, inflammation and cancer by utilizing biochemical as well as whole animal approaches.
