Bulk quantities of proteins are available. Please contact us for bulk pricing.
IL-22 is a member of the IL-10 family, which includes IL-19, IL-20, IL-24, and IL-26. This family represents a class of potent mediators of cellular inflammatory responses. IL-22 shares use of IL-10R2 in cell signaling with other members of this family. IL-22 is produced by activated DC and T cells and initiates innate immune responses against bacterial pathogens, especially in epithelial cells such as respiratory and gut epithelial cells. IL-22 along with IL-17 is rapidly produced by a subset of splenic cells and can also be produced by Th17 cells. IL-22 likely plays a role in the coordinated response of both adaptive and innate immune systems.

Abstract
Neonatal inflammatory diseases are associated with severe morbidity, but the inflammatory factors underlying them and their potential effector mechanisms are poorly defined. Here we show that necrotizing enterocolitis in neonate mice is accompanied by elevation of IL-23 and IL-22 and decreased production of pancreatic enzymes. These phenotypes are mirrored in neonate mice overexpressing IL-23 in CX3CR1+ myeloid cells or in keratinocytes. The mice fail to grow and die prematurely, displaying systemic inflammation, nutrient malabsorption and decreased expression of intestinal and pancreatic genes mediating digestion and absorption of carbohydrates, proteins, and lipids. Germ-free environment improves, and genetic ablation of IL-22 restores normal growth in mice overexpressing IL-23. Mechanistically, IL-22 acts directly at the level of pancreatic acinar cells to decrease expression of the pancreas associated transcription factor 1a (PTF1a). These results show that augmented production of IL-23 and IL-22 in early life has a negative impact on pancreatic enzyme secretion and food absorption.
