Description
Purity>95% SDS-PAGE.IL‑36 alpha is mainly found in skin and lymphoid tissues, but also in fetal brain, trachea, stomach and intestine. It is expressed by monocytes, B and T cells. The receptor for IL‑36 alpha is a combination of IL‑1 Rrp2 (also called IL‑1 RL2 or IL‑1 R6), mainly found in epithelia and keratinocytes, and the widely expressed IL‑1 RAcP. IL‑36 alpha, beta and gamma all activate NF‑ kappa B and MAPK pathways in an IL‑1 Rrp2 dependent manner, and induce production of inflammatory cytokines and chemokines such as CXCL8/IL‑8. IL‑36 alpha and other family members are overexpressed in psoriatic skin lesions, and transgenic overexpression of IL‑36 alpha in skin keratinocytes produces epidermal hyperplasia. IL‑36 alpha is present in kidney tubule epithelia; it is highly overexpressed in tubulointerstitial lesions in mouse models of chronic glomerulonephritis, lupus nephritis and diabetic nephritis. IL‑36 alpha is induced by inflammation in adipose tissue‑resident alternately activated (M2) macrophages, and reduces adipocyte differentiation
