Research Interests:

T cell response to infection

Our laboratory examines the immune response to infection with the long-term goal of more rational vaccine design. Since available vaccines can efficiently prime antibody-mediated immunity, we primarily focus on examining the biology of how pathogen-specific CD4 and CD8 T cells are primed, activated, and differentiate from effector into memory cells. For these studies, we use Listeria monocytogenes infection in the mouse as an experimental model, and combine making modifications in either the pathogen and/or the host to examine the biological parameters necessary for generating protective T cell immnity. Current ongoing work focuses on (1) defining the innate cytokine mileau that results in activation and differentiation of antigen-specific CD4 and CD8 T cells, (2) testing the ability of recombinant Listeria for use as vaccine vectors after expression heterologous antigens from other pathogens into attenuated Listeria strains, and (3) exploring potential differences priming T cell mediated immunity in neonates compared with adults.
