Figure Lengend Snippet: The influence of tested extracts (50 μg/mL) and rosavin (0.1–5 μM) on TNF-α secretion by LPS-stimulated microglia BV2. Data from three separate experiments assayed in duplicate are expressed as mean ± SEM. Dexamethasone (DEX, 20 μM) was used as a positive control. Absorbance values for all samples were expressed as percentages relative to the LPS-stimulated control (KST), which was set at 100%. Statistical significance: * p < 0.05, ** p < 0.01, *** p < 0.001 vs. stimulated control (KST), # statistically significant ( p < 0.001) vs. non-stimulated control (KNST).
