The Peters lab is focused on the immuno-biology of chronic infectious diseases, with a special emphasis on vector transmitted and neglected tropical diseases. The lab employs cutting edge multicolor flow cytometry and two-photon microscopy to unravel the intricacies of host-pathogen interactions in the skin and internal organs employing the Leishmania model of parasitic disease. Our research investigates the earliest events in the host response, including inflammatory cell interactions with vector inoculated parasites, and the regulation and expression of immunity to reinfection, including an exploration of the concept of immune memory during chronic infections.
