The expressions of PD-L1 and PD-1 on NK cells (marked with CD3−CD56+) in T2D patients and healthy donors. (a) Typical flow cytometry analysis of the PD-L1 expression on NK cells (left) and the statistical graph (right) are shown for the T2D patients (n = 23, 13.37 ± 1.19%) and healthy donors (n = 20, 14.04 ± 1.13%). (b) Typical flow cytometry analysis of the PD-1 expression on NK cells (left) and the statistical graph (right) are shown for the T2D patients (n = 23, 15.89 ± 0.77%) and healthy donors (n = 20, 19.68 ± 0.83%). (c) Correlation analysis of the PD-1 expression on NK cells and age, fasting plasma glucose (FPG), glycated hemoglobin (HbA1C), body mass index (BMI), insulin, and diabetes duration. ∗ P < 0.05 and ∗∗ P < 0.01.
