The biological activity of IL-2 is mediated by binding to a cell surface receptor complex consisting of . As a consequence, three intracellular signaling pathways are initiated, the MAP kinase pathway, the Phosphoinositide 3-kinase (PI3K) pathway, and the JAK-STAT pathway. The discovery of interleukin-2 (IL-2) changed the molecular understanding of how the immune system is controlled. Interleukin-2 receptor (IL-2R) signaling regulates tolerance and immunity. our group has previously developed several such interleukin mediated signaling pathways including il-1, il-2, il-3, il-4, il-5, il-6, il-7, il-9 and il-11 (balakrishnan et al. IL-2 signaling pathways and regulation The pleiotropic effects of IL-2 are enabled due to the fact that IL-2 signal can be transduced via 3 different signaling pathways; JAK-STAT, PI3K/Akt/mTOR and MAPK/ERK pathway. The initial set of 10 cancer signaling pathways were developed in collaboration with the Computational Biology Center at Memorial Sloan-Kettering Cancer Center and with Gary Bader's lab at the University of Toronto for the ' Cancer Cell Map '. Authors Michelle M Fung . In vitro, genome-wide transcriptomic analysis revealed alterations in calcium signaling pathways in Treg following treatment with ZA.

Here, we showed that Themis plays an important role in IL-2 and IL-15 signaling by facilitating downstream activation of the Janus kinase-signal transducer and activator of transcription (Jak-Stat) pathway and mechanistic target of rapamycin (mTOR)-mediated metabolic reprograming. In contrast to its proliferative effects, IL-2 also has potent . These kinases in turn phosphorylate IL-2R and induce tyrosine phosphorylation of STATs (signal transducers and activators of transcription) and various other downstream targets. Here, we review recent work concerning the structure, signaling, and function of the IL-2R, emphasizing the contribution of IL-2 for T cell-dependent activity in vivo. Subsequently, the IL-2/IL-2R interaction activates the intracellular Ras/Raf/MAPK, JAK/STAT, and PI3K/AKT signal pathways, and ultimately stimulates the growth, differentiation, and survival of T cells.
