Background

Interleukin 22 (IL-22) is a member of the human type I interferon family, which includes IL10. IL-22 has the potential to interact with IL10 because it binds to the IL-10R2c chain with IL-22R1 in its receptor complex. Binding can be blocked by the soluble receptor, IL-22 binding protein (IL-22BP). Although known as a Th17 cytokine, IL-22 is also expressed by a wide range of immune cells, including NK T, γδ T, and NK cells. IL-22 can contribute to immune disease through the stimulation of inflammatory responses, S100s and defensins. IL-22 also promotes hepatocyte survival in the liver and epithelial cells in the lung and gut similar to IL-10.
