NCI: Interleukin 4 (IL-4) is a cytokine that can lead to development of Th2 cells. The 140 kD IL-4 Receptor (CD124) is found on many cell types, even those of non-hematopoietic origin. The receptor is formed from two chains: IL-4R-alpha and the IL-2R gamma chain (CD132). Primary signaling is through the JAK/Stat6 pathway and MAPKs.
