The percentage of TNFa-positive hMDMs was not different between active TB patients and LTBI cases after ESAT-6 1 μg/ml (24.6 ± 16.2% vs. 18.2 ± 10.7%, P = 0.404), ESAT-6 5 μg/ml (30.3 ± 11.8% vs. 32.9 ± 12.6%, P = 0.805), and LPS 1 μg/ml (40.2 ± 22.7% vs. 42.9 ± 23.3%, P = 0.644) stimulations. This evidence concerns the gene TNF and tuberculosis.
