Abstract

After an introduction on the entry and lifestyle ofListeria monocytogeneswithin mammalian eucaryotic cells, this chapter gives a brief overview of murine experimental listeriosis. Among the main characteristics of this murine model of infectious/pathogenic processes initiated by a facultative intracellular bacteria, we point out two main recent advances. One relates toListeria monocytogenes-induced production of cytokines as local, and transient signals able to direct the immune responses along a type 1 pathway of CD4/CD8 T cell differentiation. The other relates (a) to the recognition ofL. monocytogenes-reactive CD8+T lymphocytes as effectors able, once recruited within infected loci, to critically contribute to the complete clearance of the bacteria, and (b) to the recently recognized specificity of some of these CD8 lymphocytes in BALB/c mice. In this paper, we also briefly review (a) the readout assays presently used to monitor the outcome of the infectious/pathogenic processes and the related development and expression of immune responses induced by intravenous inoculation of wild-type virulent or attenuatedL. monocytogenes, (b) why all this information allows us to consider the use ofL. monocytogenesof attenuated virulence as relevant live recombinant vectors in order to deliver heterologous proteins to the class I processing and presentation pathway, and to induce CD8 T cells along the type 1 pathway.
