Key examples include EsxA and EsxB, CpnT\/TNT, phosphatases (SapM, PtpA, PtpB), protein kinase G (PknG), the antigen 85 (ag85) complex, acyl Carrier Protein (AcpM), lipoproteins, and heat shock proteins (Hsps). Together, these secreted factors disrupt host immune responses such as phagosome maturation, antigen presentation, cytokine production, and autophagy thereby aiding in survival of these obligate intracellular bacteria. Several secreted proteins are emerging as therapeutic targets to help meet the need for shorter, more effective, and better tolerated treatment regimens for tuberculosis.
