β-Sitosterol Alleviates Inflammatory Response via Inhibiting the Activation of ERK/p38 and NF-κB Pathways in LPS-Exposed BV2 Cells

Figure 3

The effect of BS on the protein expression of proinflammatory mediators in BV2 cells. The cells were pretreated with BS for 2 h prior to the stimulation of LPS (100 ng/mL). After 24 h, the cells and the supernatant were collected, then the protein levels of proinflammatory mediators were tested by ELISA (IL-6 (a) and TNF-α (b)) and western blot (iNOS and COX-2)(c–e). The results were presented as (). ^## versus the control group. and versus the LPS-stimulated group.
