Exploiting cell death pathways by an E. coli cytotoxin: autophagy as a double-edged sword for the host.

abstract：:Autophagy has recently been implicated in the host defense against the intracellular protozoan pathogen, Toxoplasma gondii, a major opportunistic pathogen of the central nervous system in immunosuppressed individuals. In both IFN gamma-activated macrophages and astrocytes, the p47 GTPases traffic to the T. gondii para...
