Anti-inflammatory cytokines TGF-β1, IL-4, and IL-10 in primary mouse astrocyte cell cultures stimulated for 4 hr with LPS 6.25 ng/ml and/or 12 mM sodium acetate, with 12 mM NaCl as control. Panel A shows representative images of the Western blots. Panels B, D and F show the optical densities of the anti-inflammatory cytokines TGF-β1, IL-4, and IL-10, respectively, normalized to the loading control α-tubulin (n = 6). Panels C, E and G show the changes in the mRNA levels of the anti-inflammatory cytokines TGF-β1, IL-4, and IL-10, quantified by qrt-PCR and normalized to β-actin (n = 6). All values represent the mean fold change relative to control ± SD. Statistical significance (a = compared to NaCl, and b = compared to LPS) was set at p ≤ 0.05, as determined by One Way ANOVA followed by Tukey’s post-hoc test.
