CD4+ T helper cells orchestrate and regulate adaptive immune responses. From a functional perspective, they can be classified into CD4+ regulatory T cells (Treg) that show immunosuppressive activity and into CD4+ T effector cells that combat infectious pathogens. An important aspect of antimicrobial activity is the choice of the appropriate weaponry suitable to combat a particular class of pathogens. This selection is facilitated by distinct subsets of CD4+ T effector cells that produce cytokines to which the respective immune effectors are responsive. Thus, type 1 CD4+ T effector cells (Th1 cells) secrete IFN
and TNF
to recruit macrophages for combating bacterial infections [27], or IL-2 to license cytotoxic CD8+ T cells for killing virally infected cells [8]. They also stimulate B cells to produce opsonizing and neutralizing antibodies that intercept circulating pathogens. In contrast, Th2 cells secrete IL-4, IL-5 and IL-13 to recruit a different | A novel CD4+ T-effector-cell subset distinct from Th1 and Th2 |
