Fig. 1From: Saxifragifolin D attenuates phagosome maturation arrest in Mycobacterium tuberculosis-infected macrophages via an AMPK and VPS34-dependent pathwayMTT assays for cell viability. THP-1-derived macrophages or A549 cells propagated in RPMI 1640 culture medium were used as negative controls. Cells were exposed to different concentrations of SD. Data are represented as the mean ± SD; n = 4, *P < 0.05 versus THP-1controls; **P < 0.05 versus A549 controlsBack to article page
