PTPRC and inflammatory bowel disease: Proinflammatory ILC1, on the other hand, were higher in IBD patients than in HCs (9.07 vs. 1.24% of total ILC; 0.28 vs. 5.5 × 10−3 % of total CD45, both p < 0.001) and the same was found for precursor NCR− ILC3 (25.20 vs. 4.76% of total ILCs, p = 0.002; 0.06 vs. 0.02% of total CD45, p = 0.006; Figures 1C–F).
