Background

IL-2 (Interleukin-2) is an interleukin, a type of cytokine signaling molecule in the immune system. It regulates white blood cells (leukocytes, often lymphocytes) that are responsible for immunity. The major sources of IL-2 are activated CD4+ T cells and activated CD8+ T cells. IL-2 mediates its effects by binding to IL-2 receptors which are expressed by lymphocytes. IL-2 signal can be transduced by 3 different signaling pathways: JAK/STAT, PI3K/Akt/mTOR and MAPK/ERK pathway. IL-2 plays a role in regulating the adaptive immune system by controlling the survival and proliferation of regulatory T-cells, which are required for the maintenance of immune tolerance. It also promotes proliferation of activated B cells and subsequently immunoglobulin production.
