The neuro-inflammation is well known to be an inflammatory response in the brain tissue. Anti-inflammatory therapy in ischemia/reperfusion (I/R) pathogenesis is a potential therapeutic strategy for post-I/R injury. Currently, we made attempt to scrutinize the neuro-protective effect of tangeretin against I/R injury in the brain of experimental rats. I/R injury is induced in the brain via transient middle cerebral artery occlusion (2 h) and reperfusion (20 h). The infarction area, brain water content and neurofunctional parameters were also estimated. Inflammatory cytokines and brain injury markers were scrutinized at the end of the study. mRNA expression of interleukin 6 (IL-6), toll-like receptor-4 (TLR-4), interleukin 1β (IL-1β), tumor necrosis factor-α (TNF-α), interferon-γ (IFNG-γ), and transforming growth factor-β1 (TGF-β1) was estimated using the qRT-PCR. Tangeretin significantly (P < 0.001) decreased brain water content, infarct volume, neurological score, brain edema, and Evans blue leakage. Tangeretin significantly (P < 0.001) down-regulated the inflammatory and pro-inflammatory cytokines and oxidative stress parameters in the serum and brain tissue of experimental rats. qRT-PCR data demonstrated that rats treated with tangeretin could significantly (P < 0.001) suppress the IL-1β, TLR-4 TNF-α, IFNG-γ, and IL-6 and boost the expression of TGF-β1 compared with I/R injury rats. The result clearly showed tangeretin neuro-protective and anti-inflammatory effect against I/R injury in rats through suppressed inflammatory reaction.

橘皮素对大鼠脑缺血再灌注损伤的神经保护和抗炎作用。

众所周知,神经炎症是脑组织中的炎症反应。缺血/再灌注 (I/R) 发病机制中的抗炎治疗是 I/R 后损伤的潜在治疗策略。目前,我们试图仔细研究橘子对实验大鼠大脑 I/R 损伤的神经保护作用。通过短暂的大脑中动脉闭塞 (2 小时) 和再灌注 (20 小时) 在大脑中诱导 I/R 损伤。还估计了梗塞面积、脑含水量和神经功能参数。研究结束时检查了炎症细胞因子和脑损伤标志物。白细胞介素6(IL-6)、toll样受体4(TLR-4)、白细胞介素1β(IL-1β)、肿瘤坏死因子-α(TNF-α)、干扰素-γ(IFNG-γ)的mRNA表达, 使用 qRT-PCR 估计转化生长因子-β1 (TGF-β1)。Tangeretin 显着 (P < 0.001) 降低脑含水量、梗死体积、神经系统评分、脑水肿和伊文思蓝渗漏。Tangeretin 显着(P < 0.001)下调实验大鼠血清和脑组织中的炎症和促炎细胞因子和氧化应激参数。qRT-PCR 数据表明,与 I/相比,用橘皮素处理的大鼠可显着(P < 0.001)抑制 IL-1β、TLR-4 TNF-α、IFNG-γ 和 IL-6,并提高 TGF-β1 的表达。 R损伤大鼠。结果清楚地表明,橘皮素通过抑制炎症反应对大鼠 I/R 损伤具有神经保护和抗炎作用。梗死体积、神经评分、脑水肿和埃文斯蓝渗漏。Tangeretin 显着(P < 0.001)下调实验大鼠血清和脑组织中的炎症和促炎细胞因子和氧化应激参数。qRT-PCR 数据表明,与 I/相比,用橘皮素处理的大鼠可显着(P < 0.001)抑制 IL-1β、TLR-4 TNF-α、IFNG-γ 和 IL-6,并提高 TGF-β1 的表达。 R损伤大鼠。结果清楚地表明,橘皮素通过抑制炎症反应对大鼠 I/R 损伤具有神经保护和抗炎作用。梗死体积、神经评分、脑水肿和埃文斯蓝渗漏。Tangeretin 显着(P < 0.001)下调实验大鼠血清和脑组织中的炎症和促炎细胞因子和氧化应激参数。qRT-PCR 数据表明,与 I/相比,用橘皮素处理的大鼠可显着(P < 0.001)抑制 IL-1β、TLR-4 TNF-α、IFNG-γ 和 IL-6,并提高 TGF-β1 的表达。 R损伤大鼠。结果清楚地表明,橘皮素通过抑制炎症反应对大鼠 I/R 损伤具有神经保护和抗炎作用。001)下调实验大鼠血清和脑组织中的炎症和促炎细胞因子和氧化应激参数。qRT-PCR 数据表明,与 I/相比,用橘皮素处理的大鼠可显着(P < 0.001)抑制 IL-1β、TLR-4 TNF-α、IFNG-γ 和 IL-6,并提高 TGF-β1 的表达。 R损伤大鼠。结果清楚地表明,橘皮素通过抑制炎症反应对大鼠 I/R 损伤具有神经保护和抗炎作用。001)下调实验大鼠血清和脑组织中的炎症和促炎细胞因子和氧化应激参数。qRT-PCR 数据表明,与 I/相比,用橘皮素处理的大鼠可显着(P < 0.001)抑制 IL-1β、TLR-4 TNF-α、IFNG-γ 和 IL-6,并提高 TGF-β1 的表达。 R损伤大鼠。结果清楚地表明,橘皮素通过抑制炎症反应对大鼠 I/R 损伤具有神经保护和抗炎作用。
