    This demonstrates that the innate and adaptive immune response of the host in controlling TB infection is effective. Mycobacterial and host.
    Front Microbiol 2 : It consists of i the epithelium, a layer of airway epithelial cells AECs forming a barrier that prevents invasion; ii the lamina propria, a layer of connective tissue and immune cells, including lymphocytes and macrophages; and iii a coating of a highly complex substance known as airway surface liquid ASLwhich contains mucus, immunoglobulin A and an array of other innate immune factors on the luminal surface.

    Upon invading host cells through phagocytosis, Mtb can replicate within infected cells by arresting phagosome maturation. Tuberculosis ; 93 Suppl : S33—S It is clear from increasing experimental evidence and clinical observations that Mtb controls host innate immunity by dictating a sophisticated program that involves multiple host signaling pathways and cellular functions.

    Immunobiology ; : — We also describe evidence demonstrating that Mtb modulates the host innate immune defense functions to its own benefit. CLRs have been increasingly recognized to play an important role in modulating Mtb-mediated immune responses, and Mtb surface ligands, including ManLAM and cord factor, are important immune modulators that can be directly recognized by several CLRs.
