IL-22: Proteins and Enzymes

IL-22 (Interleukin-22) is a cytokine that induces the production of reactive oxygen species, IL-6, IL-10, and TNF-alpha as well as neutrophil infiltration during inflammation. It also supports the integrity of epithelial barriers and induces epithelial cell proliferation during wound healing. IL-22 signals through a receptor complex consisting of IL-22 R and IL-10 R beta. IL-10 R beta is a shared component of the receptor complexes for IL-10, IL-26, IL-28, and IL-29. IL-22 additionally binds to IL-22BP which blocks the interaction of IL-22 with IL-22 R.
