Human IL-36 gamma Recombinant Protein

Interleukin 36, or IL-36, is a group of cytokines in the IL-1 family with pro-inflammatory effects. There are four members of the IL-36 family which bind to the IL-36 receptor (IL1RL2/IL-1Rrp2/IL-36 receptor dimer) with varying affinities. IL36A, IL36B, and IL36G are IL-36 receptor agonists. IL36RA is an IL-36 receptor antagonist, inhibiting IL-36R signaling. The agonists are known to activate NF-κB and mitogen-activated protein kinases to induce various proinflammatory mediators. Binding of the IL-36R agonists to IL-1Rp2 recruits IL-1RAcP, activating the signaling pathway. IL-36Ra binds to IL-36R, preventing the recruitment of IL-1RAcP. IL-36 has been found to activate T cell proliferation and release of IL-2. Due to their predominant expression in epithelial tissues, IL-36 cytokines are believed to play a significant role in the pathogenesis of skin diseases, especially that of psoriasis. IL-36 has also been linked to psoriatic arthritis, systemic lupus erythematosus, inflammatory bowel disease, ulcerative colitis, Crohn's disease, and Sjoegren's syndrome. IL-36 is expressed by many cells types, most predominately keratinocytes, respiratory epithelium, various nervous tissue, and monocytes.
