Current Research

My laboratory is interested in studying both the basic and clinical biology of plasmactyoid dendritic cells (PDC), also known as the "natural interferon-alpha producing cells". These cells are the primary cells in the body that produce IFN in response to viral stimulation, imidizaquinilones and CpG. The PDC are important not only in the innate immune response, but also link the innate and adaptive responses by stimulating T cell resonses. We are studying basic aspects about the PDC including their phenotype, tissue distribution, mechanisms of activation (e.g. toll-like receptors, C-type lectins, IRF signaling pathways), and interaction with other cell types as well as their role and regulation in infectious diseases including HIV. In addition, recent studies have shown that PDC migrate into certain cancer tissues, and we are interested in studying the role and regulation of these cells in that setting.
