After infection, activated macrophages secrete cytokines and chemokines that activate macrophages, T cells, neutrophils, or NK cells. T cells and NK cells produce IFN-γ that acts with other cytokines to activate macrophages to produce NO, which contributes to clearance of MTb. See text for more detail.
