Of note, both IL-5 and IL-6 have been shown to play a pathogenic role in SAMP ileitis, as demonstrated by the amelioration of intestinal disease following either anti-IL-5 or anti-IL-6 treatment [50, 51], whereas IL-17 has been extensively characterized as a key cytokine in many immune-mediated diseases, including IBD [52–54]. The gene discussed is IL6; the disease is intestinal disorder.
