Of note, the Th2‐related cytokines IL‐4, IL‐5, IL‐13, and IL‐33 were upregulated by ConA in tissue from both non‐IBD and IBD patients, with absolute levels of IL‐5, IL‐13, and IL‐33 being higher in tissue from IBD patients compared with non‐IBD patients. The gene discussed is IL33; the disease is inflammatory bowel disease.
