The function of CD36⁺CD8⁺ T cells are impaired. A-C. Representative flow cytometry plots for GZMB, IFN-γ and TGF-β in CD36-positive and CD36-negative CD8⁺ T cells with quantification below of 28 patients (D-F). G-I. Correlation assessed by Pearson’s correlation analysis and linear regression analysis between proportion of CD36⁺CD8⁺ T cells and the frequencies of three effector markers in NSCLC patients based on the results of flow cytometry. *p < 0.05; ***p < 0.001; ****p < 0.0001 by paired t test
