Inducible global deletion of Crem reduced the severity of DSS colitis while increasing colonic macrophages, RORγt+ regulatory (pTregs) and T helper (Th17) cells. Future work will investigate the aforementioned cell types to determine the mechanism by which CREM aggravates DSS-colitis, thereby defining the immunoregulatory role of CREM in intestinal inflammation with the goal of identifying new therapeutic targets for IBD.
Schenck et al. (Tue,) studied this question.
