Overview

About the Interleukin-2 signaling pathway

Interleukin-2 (IL-2) is a cytokine that is produced by T cells in response to antigen stimulation. Originally, IL-2 was discovered because of its potent growth factor activity on activated T cells in vitro and was therefore named 'T cell growth factor' (TCGF). However, the generation of IL-2- and IL-2 receptor-deficient mice revealed that IL-2 also plays a regulatory role in the immune system by suppressing autoimmune responses. Two main mechanisms have been identified that explain this suppressive function: (1) IL-2 sensitizes activated T cells for activation-induced cell death (AICD) and (2) IL-2 is critical for the survival and function of regulatory T cells (Tregs), which possess potent immunosuppressive properties.
