Lineage+ IL-7R+ shown as a positive control for CTLA-4 staining on bulk T cells. d Dot plot showing the CTLA-4 gMFI in different ILC subsets (ILC1, NCR+ ILC3 and NCR- ILC3) in patients with IBD (n = 5) compared with healthy controls (n = 5) * P = 0.0423 ** P = 0.0036 2-way ANOVA with Šídák’s multiple comparisons Test.
