BMDMs were pretreated with 2DG (10 mM) for 1 h followed by challenge with S. aureus (SA) for indicated time-points. Cells were harvested and subjected to Western blotting for pERK, ERK and HSP90 proteins (A). BMDMs were pretreated with either 2DG (10 mM) or ERK inhibitor U0126 (10 μM) for 1 h, followed by a challenge with SA for 8 h. Cells were harvested and subjected to Western blotting for pERK, ERK and HSP90 proteins (B). The conditioned media from 2DG and U0126 pretreated cells in the presence and absence of SA were subjected to ELISA (C). Data represent mean ± SD from three independent experiments. A one-way ANOVA with Tukey post hoc test was used to determine statistical significance. **p<0.01, ***p<0.001, ns: not significant.
