Regulatory T (Treg) cells maintain the balance between immune protection and pathology. Research has now found that intestinal Treg cells produce IL-27 to restrain TH17 cell-mediated immune responses, effectively restricting autoimmune inflammation and limiting T cell responses to certain gut pathogens.
