WebOne IRG in particular, Irgm1, is essential for macrophage host defense against phagosomal pathogens, including Mycobacterium tuberculosis (Mtb). Here we show that Irgm1 targets the mycobacterial phagosome through lipid-mediated interactions with phosphatidylinositol-3,4-bisphosphate (PtdIns(3,4)P 2) and PtdIns(3,4,5)P 3. An isolated Irgm1 ... WebMar 15, 2024 · These proteins modify the ability of Irgm1 to enhance immunity to Mtb phagosomes via its interaction with SNARE effectors (Tiwari et al., 2009). Despite these observations, few studies have sought to examine the role of AMPK in the modulation of SNARE as part of the autophagic flux observed during mycobacterial infection.
