We detected a skewed ILC composition in endoscopically inflamed IBD versus non-IBD and non-inflamed IBD colon, as illustrated by increased frequencies of NKp44− ILCs and ILC1s, while NKp44+ ILC3 frequencies were reduced (Figure 1B), similar to our previous findings in adult IBD.13 The gene discussed is CCL27; the disease is inflammatory bowel disease.
