Abstract:
Aim To investigate the anti-inflammatory effect of salidroside on lipopolysaccharide (LPS)-induced BV2 microglia and its mechanism. Methods The model of LPS-induced injury in BV2 microglia was established. The expression of cytokines IL-6, IL-1β and TNF-α mRNA was detected by qPCR, and the expression of Akt, p-Akt, nuclear protein NF-κB p50 protein was dectected by Western blot with different concentrations of salidroside treatment. The model was sequentially treated with PI3K inhibitor LY294002 for 30 min, and after the treatment of salidroside, the expressions of Akt, p-Akt, nuclear protein NF-κB p50, IL-6, IL-1β, TNF-α and other indicators were dectected by Western blot. Results Compared with model, salidroside reduced the expression of IL-6, IL-1β and TNF-α mRNA in BV2 microglia, improved the expression of p-Akt protein, and reduced the nuclear protein NF-κB p50. After the treatment of LY294002, salidroside had no obvious effect on the expression of p-Akt, nuclear protein NF-κB p50, IL-6, IL-1β. Conclusions Salidroside can inhibit LPS-induced BV2 microglia inflammatory reaction by activating PI3K/Akt signaling pathway, promoting Akt phosphorylation, inhibiting NF-κB p50 nuclear transcription, and inhibiting cytokines.
