Proportion of secreted TNF-α-producing cells in Mtb-HAg and recombinant protein-stimulated peripheral blood γδ T cells and αβ T cells. A Flow cytometric analysis of TNF-α production by specifically expanded γδ T cells. B Statistical analysis of TNF-α production by specifically expanded γδ T cells (***P < 0.001, **P < 0.01). C Flow cytometric analysis of TNF-α production by specifically expanded αβ T cells. D Statistical analysis of TNF-α production by specifically expanded αβ T cells (***P < 0.001, **P < 0.01)
