Here we report a novel regulatory mechanism for autophagy-mediated degradation of Mycobacterium tuberculosis (Mtb) and specific strategy exploited by the virulent Mtb to evade it. We show while both avirulent (H37Ra) and virulent (H37Rv) mycobacteria could readily localize to autophagosomes, their maturation into autolysosomes (flux) was significantly(More)
Intercellular adhesion molecules (ICAMs) belong to the immunoglobulin superfamily and participate in diverse cellular processes including host-pathogen interactions. ICAM-1 is expressed on various cell types including macrophages, whereas ICAM-4 is restricted to red blood cells. Here we report the identification of an 11-kDa synthetic protein, M5, that(More)
The role of Golgi apparatus during phagocytic uptake by macrophages has been ruled out in the past. Notably, all such reports were limited to Fcγ receptor-mediated phagocytosis. Here, we unravel a highly devolved mechanism for recruitment of Golgi-derived secretory vesicles during phagosome biogenesis, which was important for uptake of most cargos, except(More)
