IL-2 is a multifunctional cytokine with pleiotropic effects on several cells of the immune system. IL-2 acts on additional cell types, such as B cells, NK cells, monocytes and macrophages. Furthermore, co-localization of the nuclear factor of activated T cells (NFAT) and forkhead box P3 (FOXP3) was significantly reduced in Treg upon ZA-treatment. These enzymes are activated by IL-2 binding to the external domains of the IL-2R. Interleukin-2 (IL-2) is an O-glycosylated four alpha-helix bundle cytokine that is primarily produced by activated T cells, dendritic cells, and B cells. Indeed, IL-2 potentiated ERK activation and subsequent BACH2 and IRF8 downregulation, sustaining BLIMP1 expression, the master regulator for PC differentiation. Here, we provide evidence for the existence of a third, rapamycin-sensitive pathway, which- results in the induction of another proto-oncogene, bcl-2. 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. The downstream signaling pathways activated by IL-2 also involves mitogen-activated protein kinase and phosphoinositide 3-kinase signaling modules, leading to both mitogenic and anti-apoptotic signals. 6A). Several signaling pathways were analyzed in WT and IL-38 / mice (Fig. 2019 Feb;37 (1):9-16. doi: 10.1007/s10637-018-0606-9. }, author={Ruslan Medzhitov and Paula Preston-Hurlburt and Elizabeth B Kopp and Andrew Stadlen and C Chen and S S Ghosh and C A Janeway . 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.

After IL-2 binding to its receptor, cytoplasmatic domains of CD122 and CD132 heterodimerize. However, IL-6 can also activate trans-signaling in cells that express gp130, but lack expression of IL-6 R alpha. Recognition and binding of the foreign antigens by the TCRs stimulate both the secretion of IL-2 and the expression of IL-2R on the T cell surface. These kinases in turn phosphorylate IL-2R and induce tyrosine phosphorylation of STATs (signal transducers and activators of transcription) and various other downstream targets. In CD4 + Treg cells, the IL-2 signaling pathway stabilizes the FoxP3 expression mediated by signal transducers and activators of transcription 5 (STAT5), thus inhibiting the function of CD4 + Tregs [1], [14], [35].
TRAF6 is the earliest reported mediators in the 1L-17RA signaling pathway. Finally, IL-2STAT5 signaling is among pathways tuned down by miR-71, via downregulation of several genes, which is another key element of the transcriptional network for Th2 cell differentiation. The downstream signaling pathways activated by IL-2 also involves mitogen-activated protein kinase and phosphoinositide 3-kinase signaling modules, leading to both .

As classic IL-6 signaling relies on the expression of membrane-bound IL-6 R alpha, it is primarily limited to hepatocytes, macrophages, neutrophils, and resting lymphocytes. 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 '.
