Listeria monocytogenes (L. monocytogenes) is a promising candidate vaccine vector that naturally infects antigen-presenting cells, and targets antigen delivery to both the class I MHC pathway of endogenous antigen presentation and the class II pathway of exogenous antigen presentation. At the same time, L. monocytogenes stimulates the innate immune response to produce cytokines that enhance antigen-presenting function and induce a Th1-type cytokine profile associated with cell-mediated immune responses. Immune responses with these features are considered to be particularly important for clearance of viruses, tumors, and intracellular infections. In this review, we describe the development of methods to transform L. monocytogenes to express and secrete foreign antigens and the studies that have demonstrated that genetically engineered L. monocytogenes mutants are highly effective vectors for the induction of potent immune responses against viral antigens and tumor cells. In addition, we discuss the strengths and weaknesses of L. monocytogenes as a vaccine vector.
