    Macrophage polarization is crucial in tuberculosis progression, influenced by local tissue microenvironments and fibrosis severity.

  • 2

    Mixed M1/M2-polarized macrophages correlate with pathogen control, while suppressed macrophages exhibit an M0-like state with higher Mtb loads.

  • 3

    The study highlights the complexity of macrophage phenotypes and signaling pathways in lung TB lesions, essential for developing new therapies.

  • 4

    Defining macrophage dynamics in TB is vital for designing host-directed therapies to enhance immune responses against Mtb.

  • 5

    The ongoing spread of drug-resistant TB necessitates improved treatment strategies based on understanding macrophage polarization.
