PG - 386-398 AB - Dendritic cells (DCs) and macrophages (Mvarphis) are professional antigen-presenting cells (APCs) that can efficiently phagocytose Mycobacterium tuberculosis (Mtb), the etiological agent of tuberculosis (TB). It is quite interesting to mention here that DCs and Mvarphis use distinct strategies to combat and eliminate Mtb. Similarly, Mtb employs different mechanisms to counteract the action of DCs and Mvarphis. Mvarphis are evolved with specialized, innate, defensive machinery to restrict growth of Mtb at the initial phase of infection. However, DCs are more endowed toward initiating adaptive immunity by activating naive T cells. During encounter with Mtb, DCs and Mvarphis deliver discrete functions via triggering through different pattern recognition receptors (PRRs) expressed by these APCs. Mtb-infected DCs and Mvarphis show differential expression of genes encoding cytokines, chemokines, costimulatory molecules, and adhesion molecules. Interestingly, Mtb impairs the immune defensive machinery by exploiting various PRRs. Remarkably, selective signaling through PRRs by Mtb abrogates the bactericidal activity of Mvarphis, but subverts differentiation of monocytes to DCs. In this article, we highlight the role of PRRs in inducing distinct immune response by DCs and Mvarphis against Mtb. Concurrently, we also discuss smart strategies exploited by Mtb to impair the function of host DCs and Mvarphis.
