(E and F) THP-1 cells transfected with mock, Eis-WT, or Eis-ΔAT constructs were pretreated with SP600125 (SP; 20 µM) or SB203580 (SB; 5 µM) for 45 min before infection with Mtb-Δeis for 30 min (E) or 18 h (F). E, Intracellular superoxide production was analyzed by flow cytometric analysis. F, ELISA analysis for TNF-α and IL-6 levels. Data are presented as the mean±SD of three experiments. **p<0.01, ***p<0.001, vs. SC (A, C, E, and F); mock control (B and D). UI, uninfected; SC, solvent control (0.1% DMSO).
