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 (DC), 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 human IL-22BP contains two Fibronectin type-III domains (4, 6). Alternative splicing generates additional isoforms that contain a 32 amino acid (aa) insertion in the first Fn-III domain and may also be truncated within the second Fn-III domain (3, 4, 14). Human IL-22BP without the 32 aa insertion shares 68% and 73% amino acid (aa) sequence identity with mouse and rat IL-22BP, respectively.
