摘要：

探讨小续命汤提取物(Xiao-Xu-Ming decoction extract, XXM)对脂多糖(lipopolysaccaride, LPS)诱导的体内外神经炎症的影响。体外实验应用200 ng/mL LPS处理BV2小胶质细胞24小时以诱导炎症反应。体内实验应用5 mg/kg LPS诱导小鼠炎症反应。Griess试剂测定NO含量; ELISA法测定IL-1β、IL-6、TNF-α和MCP-1的含量; WB检测Iba-1、TLR4和MyD88蛋白的表达; RT-PCR测定TLR4和MyD88的mRNA水平。结果发现, 在体外细胞上, XXM显著降低LPS诱导的BV2细胞上清液中NO、IL-1β、IL-6和TNF-α的水平增高, 抑制LPS诱导的BV2细胞中炎症蛋白TLR4和MyD88的表达。在小鼠脑皮层组织中, XXM显著抑制LPS诱导的小胶质细胞活化, 降低LPS诱导的炎症因子和趋化因子IL-1β、IL-6、TNF-α和MCP-1的水平增高, 抑制LPS诱导的TLR4和MyD88蛋白的表达。结果表明, XXM可下调TLR4/MYD88信号通路来减轻LPS诱导的神经炎症反应。

Abstract:

In the present study, we aimed to investigate the effects of Xiao-Xu-Ming decoction extract (XXM) on lipopolysaccaride (LPS)-induced neuroinflammation invitro and invivo. Invitro, the microglia BV2 cells were treated with 200 ng/mL LPS for 24 h to induce inflammatory responses. Invivo, mice were treated with 5 mg/kg LPS to induce inflammatory responses. The NO level was determined by Griess Reagents. The levels of IL-1β, IL-6, TNF-α and MCP-1 were determined by ELISA. The expressions of Iba-1, TLR4 and MyD88 at the protein levels were determined by Western blotting analysis. The mRNA levels of TLR4 and MyD88 were determined by real-time PCR. Invitro, XXMsignificantly reduced the levels of various pro-inflammatory factors, including NO, IL-1β, IL-6 and TNF-α, induced by LPS in the supernatant of BV2 cells and suppressedexpressions of inflammatory proteins TLR4 and MyD88 induced by LPS in BV2 cells. Invivo, XXM significantly inhibited microglia activation, attenuated LPS-induced inflammatory factors and chemokine production, such as IL-1β, IL-6, TNF-α and MCP-1, andinhibited the expressions of inflammatory proteins including TLR4 and MyD88, in the cortex of LPS-induced mice. Our findings suggested that XXM could attenuate LPS-induced neuroinflammation via down-regulating TLR4/MyD88 signaling pathway.
