摘要
Immunity-related p47 guanosine triphosphatases (IRG) play a role in defense against intracellular pathogens. We found that the murine Irgm1 (LRG-47) guanosine triphosphatase induced autophagy and generated large autolysosomal organelles as a mechanism for the elimination of intracellular Mycobacterium tuberculosis. We also identified a function for a human IRG protein in the control of intracellular pathogens and report that the human Irgm1 ortholog, IRGM, plays a role in autophagy and in the reduction of intracellular bacillary load.
