Background: IL-22BP
Interleukin 22 binding protein (IL-22BP), also known as CRF2-10, CRF2-X, and IL-22 RA2, is a 35-45 kDa secreted glycoprotein in the type II cytokine receptor family (CRF). IL-22 signals through a receptor complex consisting of IL-22 R and IL-10 R beta. IL-10 R beta is also a component of the receptor complexes for IL-10, IL-26, IL-28, and IL-29 (1, 2). IL-22BP blocks the interaction of IL-22 with IL-22 R, preventing IL-22 induced production of reactive oxygen species, IL-6, IL-10, and TNF-a (3-8). In vivo, it regulates the proinflammatory effects of IL-22 ( e.g. neutrophil infiltration) but not of IL-10 (7). Mouse IL-22BP can neutralize the bioactivity of both mouse and human IL-22 (6). IL-22BP is produced by dendritic cells (DE), epithelial cells, activated B cells, and activated monocytes (3, 6, 9, 10). It is constitutively expressed by DC but is down-regulated during local inflammation and in response to tissue damage (11-13). IL-22BP is critical for limiting IL-22 induced epithelial cell proliferation during wound healing, and its deficiency can enable uncontrolled proliferation and enhance tumor development (12). Mature mouse IL-22BP consists of two tandem Fibronectin type-III domains and shares 85% and 68% amino acid sequence identity with rat IL-22BP and the short isoform of human IL-22BP, respectively (6, 14).
