Expression of PD1 and CTLA-4 on ILC populations. Expression of PD1 (a left graph) and CTLA-4 (a right graph) on ILC groups in peripheral blood of patients with malignant breast tumour (n = 14–16), benign breast tumour tissue (n = 4) and malignant breast tumour tissue (n = 14–16) determined by flow cytometry. Expression of PD1 (b left graph) and CTLA-4 (b right graph) on ILC groups in peripheral blood of patients with malignant GI tumour (n = 8–12), para-lesional tumour tissue (n = 8–12) and malignant GI tumour tissue (n = 8–12)
