Cytolysis, interferon gamma and tumor necrosis factor (TNF) alpha secretion are major effector mechanisms of memory CD8+ T cells that are believed to be required for immunological protection in vivo. By using mutants of the intracellular bacterium Listeria monocytogenes, we found that none of these effector activities is sufficient to protect against… (More)
Memory CD8(+) T lymphocytes are critical effector cells of the adaptive immune system mediating long-lived pathogen-specific protective immunity. Three signals - antigen, costimulation and inflammation - orchestrate optimal CD8(+) T-cell priming and differentiation into effector and memory cells and shape T-cell functional fate and ability to protect… (More)
Induction of efficient adaptive T cell-mediated immunity against the intracellular bacterium Listeria monocytogenes requires its successful invasion of host cell cytosol. However, it is not clear whether its cytosolic escape and growth are sufficient to induce T cell-mediated clearance and protection upon secondary infection. To investigate this issue, we… (More)
The SecA2 auxiliary secretion system of Gram-positive bacteria promotes the export of virulence proteins essential for colonization of the host in the case of both Mycobacterium tuberculosis and Listeria monocytogenes, two intracellular bacteria causing diseases in humans. We and others have demonstrated that this secretion system is also linked to the… (More)
The biological insecticide Thuricide is produced from B. thuringiensis, Berliner, var. kurstaki (serotype 3a, 3b), a bacterial strain which does not synthesize exotoxin. Thus, our product is devoid of any C-mitotic or mutagenic potentiality such as is to be found in exotoxin.
