PD-1 blocking antibodies can increase sensitivity to QFT-GIT in silicosis. a Analyzed the optimal working concentration (0 μg/ml, 5 μg/ml, 10 μg/ml and 20 μg/ml,) of PD-1 blocking antibody; b analysis of the PD-1 blocking antibody effect on lymphocytes in silicosis. Black: lymphocytes stimulated with PBS, Green: lymphocytes stimulated with tuberculosis antigens library (ESAT-6, CFP-10, TB 7.7), Red: lymphocytes stimulated with PHA; *p < 0.05; **p < 0.01; ***p < 0.001
