Among the ConA‐induced Th2‐associated cytokines, a significant reduction of IL‐33 (2‐fold) in tissue of non‐IBD patients, as well as significant reduction of IL‐4 (19‐fold), IL‐5 (12‐fold), IL‐13 (3‐fold), and IL‐33 (5.5‐fold) in tissue from IBD patients was observed (Figure S3). The gene discussed is IL4; the disease is inflammatory bowel disease.
