Listeria Monocytogenes

Listeria monocytogenes

Our interest in Listeria began with the initial demonstration of antigen processing and presentation to T cells. These studies were followed by examination of many early events in microbial infection including the role of inflammatory cytokines (IL-1, IL-6, IL-10, IL-12, TNF, and IFN-g), reactive oxygen/nitrogen species, and listeriosis in lymphocyte deficient strains of mice (SCID). Below are included three key papers on antigen processing using L. monocytogenes plus reviews covering the subsequent investigations.
