Abstract
Tristetraprolin (TTP, encoded by Zfp36) is an RNA-binding protein that plays a major role in the control of inflammation. Zfp36−/− mice spontaneously develop a complex multiorgan inflammatory syndrome but no overt intestinal inflammation, suggesting the involvement of local regulatory mechanisms. In this study, we observed local expansion of IL-22-producing type 3 innate lymphoid cells (ILC3s) in the lamina propria of Zfp36−/− mice. Our findings demonstrate that this expansion was primarily influenced by cell-extrinsic cues. In the absence of IL-22, we observed delayed onset of arthritis in Zfp36−/− mice but no clear evidence of exacerbated intestinal inflammation under steady-state conditions. However, we show that Zfp36−/− mice were paradoxically protected from dextran sulfate sodium (DSS)-induced colitis and suggest that increased IL-22 production by ILC3 might contribute to this observation. Taken together, these data highlight the complex interplay between systemic inflammation and gut mucosal immune homeostasis.
期刊介绍:
The European Journal of Immunology (EJI) is an official journal of EFIS. Established in 1971, EJI continues to serve the needs of the global immunology community covering basic, translational and clinical research, ranging from adaptive and innate immunity through to vaccines and immunotherapy, cancer, autoimmunity, allergy and more. Mechanistic insights and thought-provoking immunological findings are of interest, as are studies using the latest omics technologies. We offer fast track review for competitive situations, including recently scooped papers, format free submission, transparent and fair peer review and more as detailed in our policies.
