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.
