概要
OBJECTIVE
To study the inhibitory effect of Luteolin on LPS-induced BV-2 cell.
METHODS
BV-2 cells were treated with LPS (0.1 microg/mL) for inflammation model; MTT assay was used to detect the viability of BV-2 cells; Nitric oxide (NO) was detected by the method of nitric acid reductase assay; Induce type II nitric oxide synthase (iNOS) enzyme activity was determined by type of nitric oxide synthase assay;TLR4 protein expression was examined by the Western Blot analysis.
RESULTS
Luteolin significantly decreased the NO production and TLR4 protein expression as well as iNOS activity in LPS-activated microglial cell.
CONCLUSIONS
LPS induced activation of microglia lead to inflammatory response and its mechanism may be related to inhibiting TLR4 signaling pathway.
