IL-22 is a possible target for control of autoimmune diseases

IL-22 is a member of the IL-10 cytokine family and signals through a heterodimeric receptor composed of the common IL-10R2 subunit and the IL-22R subunit. IL-10 and IL-22 both activate the STAT3 signaling pathway (STAT is Signal Transducers and Activator of Transcription).

The IL-10 family includes IL-10, IL-19, IL-20, IL-22, IL-24, and IL-26.

The IL-22 pathway has emerged as a possible target for control of inflammation in certain autoimmune diseases. The findings of this study suggest that few if any infectious complications would be expected with the suppression of IL-22 signaling.
