Phenolic Glycolipid Facilitates Mycobacterial Escape from Microbicidal Tissue-Resident Macrophages

Cambier et al. find that activation of the STING pathway in lung-resident microbicidal macrophages by the mycobacterial surface lipid PGL enables bacterial escape by inducing the recruitment of mycobacterium-permissive monocytes via the CCL2-CCR2 chemokine axis. Their findings reveal a relocation strategy that enables mycobacterial dissemination, and argue for the potential of interventions targeting PGL in the prevention of tuberculosis.
