Interleukin 2 (IL-2) is a potent cytokine that can lead to cellular activation and proliferation. IL-2 Receptors are found on activated B-Cells, LPS treated Monocytes, and many T cells. The receptor is formed from three chains alpha (CD25), beta (CD122), and gamma (CD132). Primary signaling is through the JAK/Stat pathway and MAPKs.
