Differed IL-1 Beta Response between Active TB and LTBI Cases by Ex Vivo Stimulation of Human Monocyte-Derived Macrophage with TB-Specific Antigen
Figure 5
Interleukin-1 beta (IL-1b) and tumor necrosis factor-alpha (TNFa) response of human monocyte-derived macrophages in active tuberculosis (TB) patients and latent TB infection (LTBI) cases after TB-specific antigen stimulation for 6 and 24 hours by flow cytometry. E1: early secretory antigenic target-6KD (ESAT-6) 1 μg/ml; E5: ESAT-6 5 μg/ml; LPS: lipopolysaccharide 1 μg/ml.
