In the current study we determined the role of IL-21 receptor signaling in Mycobacterium tuberculosis (Mtb) infection, using IL-21 receptor knockout (IL-21R KO) mice. Fifty percent of Mtb H37Rv infected IL-21R KO mice died in six months compared to no deaths in infected wild type (WT) mice. Mtb infected IL-21R KO mice had enhanced bacterial burden and reduced infiltration of antigen specific T-cells in lungs compared to Mtb infected WT mice. Antigen specific T-cells from the lungs of Mtb infected IL-21R KO mice had increased expression of T-cell inhibitory receptors, reduced expression of chemokine receptors, proliferated less and produced less IFN- γ, compared to antigen specific T cells from the lungs of Mtb infected WT mice. T cells from Mtb infected IL-21R KO mice were unable to induce optimal macrophage responses to Mtb. This may be due to a decrease in the antigen specific T cell population. We also found that IL-21R signaling is associated with reduced expression of a transcriptional factor Eomesodermin (Eomes) and enhanced functional capacity of antigen specific T-cells of Mtb infected mice. The sum of our findings suggests that IL-21 receptor signaling is essential for the optimal control of Mtb infection.
