Toxin secretion and trafficking by Mycobacterium tuberculosis
The tuberculosis necrotizing toxin (TNT) is the major cytotoxicity factor of M. tuberculosis (Mtb). Mtb possesses five type VII secretion systems (ESX). Pajuelo et al. show that the ESX-4 system is required for TNT secretion and that ESX-2 and ESX-4 systems work in concert with ESX-1 to permeabilize...

| Sumario: | The tuberculosis necrotizing toxin (TNT) is the major cytotoxicity factor of M. tuberculosis (Mtb). Mtb possesses five type VII secretion systems (ESX). Pajuelo et al. show that the ESX-4 system is required for TNT secretion and that ESX-2 and ESX-4 systems work in concert with ESX-1 to permeabilize the phagosomal membrane and enable trafficking of TNT into the cytoplasm of macrophages infected with Mtb. |
