2G-CSF通过上调mTOR/p70S6K信号通路抑制新生大鼠HIBD后神经细胞凋亡显示文摘目的 探讨粒细胞集落刺激因子(G-CSF)对新生大鼠缺氧缺血性脑损伤(HIBD)后神经细胞凋亡的影响及哺乳动物雷帕霉素靶蛋白(mTOR)/p70S6K信号通路在其中发挥的作用. 方法 90只7d龄新生SD大鼠按随机数字表法分为假手术组、模型组、G-CSF组、雷帕霉素组及对照组,每组18只.后4组采用改良Rice-Vannucci法制备成HIBD模型,其中雷帕霉素组、对照组于HIBD前1h分别腹腔注射雷帕霉素250μg/kg或等体积乙醇;G-CSF组、雷帕霉素组及对照组于HIBD后1h腹腔注射G-CSF 50 μg/kg,假手术组、模型组予等体积生理盐水腹腔注射.HIBD后48h,采用2,3,5-三苯基氯化四氮唑(TTC)染色检测脑梗死面积并计算梗死面积比,Nissl染色评估海马CA1区及皮质神经细胞情况,TUNEL法检测海马CA1区及皮质神经细胞凋亡情况,Westernblotting检测脑组织中抗凋亡因子B淋巴细胞瘤-2基因(Bcl-2)及促凋亡因子Caspase-3活化片段(CC3)、Bcl-2相关X蛋白(Bax),mTOR、磷酸化(p)-mTOR及其下游p70S6K、p-p70S6K蛋白的表达. 结果 与模型组相比,G-CSF组和对照组梗死面积比明显减少,海马CA1区及皮质Nissl染色阳性细胞数明显增多、神经细胞凋亡指数明显降低,脑组织中CC3、Bax蛋白表达水平明显降低,Bcl-2蛋白表达水平明显升高,p-mTOR/mTOR、p-p70S6K/p70S6K比值明显升高,差异均有统计学意义(P<0.05).与G-CSF组和对照组相比,雷帕霉素组梗死面积比明显增加,海马CA1区及皮质Nissl染色阳性细胞数明显减少、神经细胞凋亡指数明显增加,脑组织中CC3、Bax蛋白表达水平明显升高,Bcl-2蛋白表达水平明显降低,p-mTOR/mTOR、p-p70S6K/p70S6K比值明显降低,差异均有统计学意义(P<0.05). 结论 G-CSF可能通过上调mTOR/p70S6K信号通路抑制HIBD后神经细胞凋亡.陈璐 舒斯云 吴政彦 马林 杜江 Dumbuya John Sieh 罗薇 李菲 王斌 2018中华神经医学杂志2018,17,5:6
3粒细胞集落刺激因子通过mTOR/p70S6K途径调节新生大鼠缺氧缺血性脑损伤后炎症反应显示文摘目的观察粒细胞集落刺激因子(G-CSF)对新生大鼠缺氧缺血性脑损伤(HIBD)后炎症反应的影响及哺乳动物雷帕霉素靶蛋白/p70核糖体S6蛋白激酶(mTOR/p70S6K)信号通路在其中发挥的作用。方法7日龄新生SD大鼠90只按随机数字表法随机分为假手术组、缺氧缺血(HI)模型组、G-CSF组、雷帕霉素组及对照组,改良Rice法建立新生大鼠HIBD模型。HI前1 h,雷帕霉素组腹腔注射雷帕霉素250 μg/kg,对照组予等体积乙醇腹腔注射。HI 1 h后,G-CSF组、雷帕霉素组及对照组腹腔注射G-CSF 50 μg/kg,HI模型组及假手术组予等体积9 g/L盐水腹腔注射。HI 48 h后,Western blot检测脑组织中肿瘤坏死因子-α(TNF-α)、白细胞介素(IL)-1β、IL-10及mTOR/p70S6K信号通路蛋白水平,尼氏染色评估海马CA1区及皮质神经元损伤情况,2,3,5-氯化三苯基四氮唑染色检测脑梗死面积。结果与HI模型组比较,G-CSF组及对照组脑梗死面积减少[(12.87±1.54)%、(11.90±1.31)%比(24.21±3.28)%],尼氏染色阳性神经元计数增多[海马CA1区:(61.00±4.90)个/视野、(61.67±6.40)个/视野比(42.67±4.46)个/视野;皮质:(92.67±6.68)个/视野、(90.17±4.45)个/视野比(70.83±6.97)个/视野],TNF-α及IL-1β水平降低(TNF-α:0.67±0.07、0.55±0.05比0.86±0.05;IL-1β:0.65±0.06、0.52±0.10比0.86±0.06),IL-10、p-mTOR/mTOR及p-p70S6K/p70S6K水平升高(IL-10:0.68±0.04、0.62±0.05比0.34±0.02;p-mTOR/mTOR:0.53±0.02、0.51±0.01比0.26±0.01;p-p70S6K/p70S6K:0.89±0.03、0.90±0.03比0.55±0.02),差异均有统计学意义(均P〈0.05)。与G-CSF组及对照组比较,雷帕霉素组脑梗死面积增加[(25.70±1.50)%],尼氏染色阳性神经元计数减少[海马CA1区:(40.67±3.50)个/视野;皮质:(68.33±8.17)个/视野],TNF-α及IL-1β水平升高(分别为0.97±0.06、0.98±0.10),IL-10、p-mTOR/mTOR及p-p70S6K/p70S6K水平降低(分别为0.21±0.02、0.30±0.01、0.55±0.01),差异均有统计学意义(均P〈0.05)。结论G-CSF可能通过上调mTOR/p70S6K信号通路抑制HIBD后的炎症反应。Dumbuya John Sieh 舒斯云 吴政彦 马林 杜江 陈璐 罗薇 李菲 王斌 2018中华实用儿科临床杂志2018,33,14:3
