Interleukin 27 is a potential rescue therapy for acute severe colitis via interleukin-10 dependent T cell independent attenuation of colonic mucosal innate immune responses

摘要

BackgroundIBD patients with acute severe colitis face systemic anti-TNF biologic rescue therapy or colectomy, if treatment with intravenous steroids fail. Interleukin (IL)-27 is a cytokine with an immunosuppressive role in adaptive immune responses. However, the IL-27 receptor complex is also expressed on innate immune cells, and there is evidence that IL-27 can impact the function of innate cell subsets, although this particular functionality in vivo is not understood. Our aim was to define the efficacy of IL-27 in acute severe colitis and characterize novel IL-27 driven mechanisms of immunosuppression in the colonic mucosa.
