Interestingly, in line with our previous report,34 we identified a SELL-expressing ILC subcluster 4 (Figures 4B and 4F), with low expression of NCR2, HLA-DR, and RORC transcripts (Figures 4B, 4D, and S4F), likely representing naive-like ILCs enriched in adult IBD. This evidence concerns the gene CCL27 and inflammatory bowel disease.
