title: Microbe-induced T cell apoptosis: subversion of the host defense system?
abstract: Cells of multicellular organisms are equipped with a self destruction program called apoptosis to ensure homeostasis of the organism. Contraction of the lymphocyte compartment following recovery from an infection is controlled by this mechanism. But apoptosis of lymphocytes might be an Achilles tendon accessible to microbes to subvert the immune system. Evidence is cumulating that microbes use this mechanism to destroy microbe-specific T cells. We present an overview of microbe-induced T cell apoptosis discussing the consequences for the pathogenesis of microbial infection. The conventional role of lymphocytes during infection is to impose apoptotic threat to infected cells, the subject of this review highlights the opposite, lymphocytes as targets of microbe-induced death.
