Abstract:

Tuberculosis (TB) caused by Mycobacterium tuberculosis has been the first cause of death for single infectious diseases since 2007. An indispensable cause of TB epidemic is that M.tuberculosis can dormant in host cells for a long time, and it has strong resistance to host defense and drug treatment. Mammalian cell entry (Mce) protein family plays a major role in M.tuberculosis invasion and intracellular survival.Among them, the mce operons (mce1-4) and the encoded Mce4 protein family are essential in the process of inducing pathogenic bacteria invasion, regulating host immunity, and ingesting and utilizing cholesterol. The authors reviews the research progress of mce4 operon and Mce4 protein family, to further comprehend the role of Mce4 proteins in the pathogenesis of M.tuberculosis and provide potential new targets for the treatment of tuberculosis.
