Abstract

Defense of the human body against damaging and pathogenic insults is a heavily regulated affair. A primary mechanism of defense at sites of insult are soluble mediators whose defensive maneuvers increase barrier integrity and promote pro-reparative and resolution processes. IL-22 is a cytokine in the IL-10 cytokine family that has garnered increased attention in recent years due to its intimate link in promoting resolution of inflammatory insults, while simultaneously being over expressed in certain fibrotic and chronic inflammatory-skewed diseases. The spatial action of IL-22 centers around the barrier sites of the body, including the skin, lungs, and gut mucosa. As such, a detailed understanding of the role of this cytokine, the producers and responders, and the diseases resulting from over- or under-expression have prominent impacts on a variety of disease outcomes. Herein we present a comprehensive review of IL-22; from historical perspectives and initial discovery, as well as more recent data that dramatically expands on the cellular sources and impact of this cytokine. We aim to showcase the duality of IL-22 and highlight addressable gaps in the field of IL-22 crosstalk and impacts at the ever-important mucosal and tissue barrier sites.
