The Mycobacterium marinum ESX-1 system mediates phagosomal permeabilization and type I interferon production via separable mechanisms
Following mycobacterial entry into macrophages the ESX-1 type VII secretion system promotes phagosomal permeabilization and type I IFN production, key features of tuberculosis pathogenesis. The current model states that the secreted substrate ESAT-6 is required for membrane permeabilization and that a subsequent passive leakage of extracellular bacterial DNA into the host cell cytosol is sensed by
