IL1A and ulcerative colitis: In the interventional studies, direct biomarker assessments of immune resolution were the number/proportion of regulatory T-cells (Treg) and the ratio Th17/Treg in SLE and rheumatoid arthritis; the number of T follicular helper cells (Tfh), Th1, Th2, Th17, and Th22 in atopic dermatitis, rheumatoid arthritis, and SLE; and mucosal proinflammatory gene signatures (tumor necrosis factor [TNF], interleukin 1 alpha [IL1A], regenerating family member 1 alpha [REG1A], IL8, interleukin 1 beta [IL1B], and leukocyte immunoglobulin-like receptors A [LILRA]) in ulcerative colitis.
