The inhibitory cytokine IL-35 contributes to regulatory T-cell function

This article has been updated

Abstract

Regulatory T (Treg) cells are a critical sub-population of CD4+ T cells that are essential for maintaining self tolerance and preventing autoimmunity1,2, for limiting chronic inflammatory diseases, such as asthma and inflammatory bowel disease3,4, and for regulating homeostatic lymphocyte expansion5. However, they also suppress natural immune responses to parasites6 and viruses7 as well as anti-tumour immunity induced by therapeutic vaccines8. Although the manipulation of Treg function is an important goal of immunotherapy, the molecules that mediate their suppressive activity remain largely unknown. Here we demonstrate that Epstein-Barr-virus-induced gene 3 (Ebi3, which encodes IL-27β) and interleukin-12 alpha (Il12a, which encodes IL-12α/p35) are highly expressed by mouse Foxp3+ (forkhead box P3) Treg cells but not by resting or activated effector CD4+ T (Teff) cells, and that an Ebi3–IL-12α heterodimer is constitutively secreted by Treg but not Teff cells. Both Ebi3 and Il12a messenger RNA are markedly upregulated in Treg cells co-cultured with Teff cells, thereby boosting Ebi3 and IL-12α production in trans. Treg-cell restriction of this cytokine occurs because Ebi3 is a downstream target of Foxp3, a transcription factor that is required for Treg-cell development and function. Ebi3–/– and Il12a–/– Treg cells have significantly reduced regulatory activity in vitro and fail to control homeostatic proliferation and to cure inflammatory bowel disease in vivo. Because these phenotypic characteristics are distinct from those of other IL-12 family members, this novel Ebi3–IL-12α heterodimeric cytokine has been designated interleukin-35 (IL-35). Ectopic expression of IL-35 confers regulatory activity on naive T cells, whereas recombinant IL-35 suppresses T-cell proliferation. Taken together, these data identify IL-35 as a novel inhibitory cytokine that may be specifically produced by Treg cells and is required for maximal suppressive activity.
