目的
2
探讨鬼针草总黄酮(TFB)对脂多糖(LPS)诱导小鼠神经炎症的改善作用及机制。
方法
2
将50只C57BL/6小鼠随机分为正常对照组、LPS组和TFB低、中、高剂量组,每组10只。TFB低、中、高剂量组小鼠按60、120、240 mg/kg灌胃TFB溶液,正常对照组和LPS组小鼠灌胃等体积生理盐水,每日1次,连续给药21 d。从给药第15天起,除正常对照组外,其余组小鼠连续7 d腹腔注射LPS(400 μg/kg)建立神经炎症模型。末次给药4 h后麻醉小鼠取脑组织。观察小鼠神经元形态变化,检测小鼠脑组织中一氧化氮(NO)和肿瘤坏死因子α(TNF-α)、白细胞介素1β(IL-1β)、IL-6、IL-10的含量,检测小鼠脑组织中炎症通路相关蛋白[诱导型NO合酶(iNOS)、环氧合酶2(COX-2)、髓样分化因子88(Myd88)及蛋白激酶C(PKC)]的表达。
结果
2
与正常对照组相比,LPS组小鼠脑组织的海马区神经元排列稀疏紊乱,大量神经元固缩,核缩小;脑组织中TNF-α、IL-1β、IL-6、NO含量均显著增加,IL-10含量显著降低,iNOS、COX-2、Myd88、PKC蛋白相对表达量均显著升高(
P
<0.05)。与LPS组相比,TFB低、中、高剂量组小鼠脑组织神经元病理变化明显改善,脑组织中上述指标变化均显著逆转(
P
<0.05)。
结论
2
TFB具有抑制神经炎症的作用,其作用机制可能与下调炎症通路相关蛋白iNOS、COX-2、Myd88和PKC表达,减少炎症因子释放有关。
OBJECTIVE
2
To investigate
the effect and mechanism of total flavonoids of
Bidens pilosa
L. (TFB) on lipopolysaccharide (LPS)-induced neuroinflammation in mice.
METHODS
2
Fifty C57BL/6 mice were randomly divided into normal control group, LPS group and TFB low-dose, medium-dose and high-dose groups, with 10 mice in each group. TFB low-dose, medium-dose and high-dose groups were given TFB solution intragastrically at 60, 120 and 240 mg/kg, and the normal control group and LPS group were given corresponding volume of normal saline, once a day, for consecutive 21 d. From the 15th day of administration, except for the normal control group, other groups were given LPS (400 μg/kg) intraperitoneally for 7 consecutive days to establish neuroinflammatory model. Brain tissues were taken under anesthesia 4 h after the final administration. The morphological changes of neuronal cells in mice were observed; the contents of nitric oxide (NO), tumor necrosis factor α (TNF-α), interleukin-1β (IL-1β), IL-6 and IL-10 were measured, and the expressions of inflammatory pathway-related proteins [inducible NO synthase (iNOS), cyclooxygenase-2 (COX-2), myeloid differentiation factor 88 (Myd88) and protein kinase C (PKC)] were measured in the brain tissues of mice.
RESULTS
2
Compared with the normal control group, the neuronal arrangement in the hippocampal region of the brain tissue of mice in the LPS group was sparsely disorganized, with a large number of neuronal fixations and shrunken nuclei; the contents of TNF-α, IL-1β, IL-6 and NO in the brain tissue were significantly increased, the contents of IL-10 were significantly decreased, and the relative expressions of iNOS, COX-2, Myd88 and PKC proteins were significantly increased (
P
<0.05). Compared with the LPS group, the neuronal pathological changes in the brain tissue of mice in the TFB low-dose, medium-dose and high-dose groups were significantly improved, and the changes of the above indices in the brain tissue we
re significantly reversed (
P
<0.05).
CONCLUSIONS
2
TFB has an inhibitory effect on neuroinflammation, and its mechanism of action may be related to down-regulation of the expressions of inflammatory pathway-related proteins iNOS, COX-2, Myd88 and PKC, and reduction of inflammatory factors release.
