WebAs their name suggests, T helper (Th) cells provide helper functions to other cells of the immune system—especially the antigen-presenting cells (APCs) such as macrophages, dendritic cells, and B cells—and are important for their activation and maturation. WebHelper T-cells aid other cells in the immune response. When they sense an infection, they release cytokines, molecules that send messages to other immune cells. These cytokines help activate cytotoxic T-cells to fight the infection. Anatomy Where are cytotoxic T -cells located? T-cells begin to form first in your bone marrow.
WebWhen developing T helper cells are treated with the pleiotropic cytokine IL-21, the IL-12/STAT4 signaling is diminished; thereby attenuating Th1 cell differentiation (Wurster et al., 2002). IL-21 inhibits IFN-γ production by developing Th1 cells in mice via eomesodermin repression (Suto et al., 2006).
