Interleukin 22 (IL22) is a member of the human type I interferon family, which includes IL10. IL22 has the potential to interact with IL10 because it binds to the IL-10R2c chain with IL22R1 in its receptor complex. Binding can be blocked by the soluble receptor, IL22 binding protein (IL22BP). Although known as a Th17 cytokine, IL22 is also expressed by a wide range of immune cells, including NK T, γδ T, and NK cells. IL22 can contribute to immune disease through the stimulation of inflammatory responses, S100s and defensins. IL22 also promotes hepatocyte survival in the liver and epithelial cells in the lung and gut similar to IL10.
