Effect of Mycobacterium tuberculosis (Mtb) infection on human monocytes in pulmonary tuberculosis (TB) patient. Human peripheral blood mononuclear cells (PBMCs) were isolated from healthy control (HC; n = 34) and pulmonary TB patients (TB; n = 34). (a) CD14-positive (CD14⁺) moncytes were sorted and determined by fluorescence-activated cell sorting (FACS). (b) Apoptosis positive cells in above primary moncytes was measured on FACS. All operations were performed in triplicate and * P < 0.05
