Description | GPI-1046 is an immunophilin ligand without antibiotic action and attenuates ethanol intake in part through the upregulation of glutamate transporter 1 (GLT1) in PFC and NAc-core. |
In vitro | GPI-1046是FK506的类似物,属于免疫复合体配体,在神经退行性疾病模型中展现出神经保护作用[1]。GPI-1046易于穿越血脑屏障,在啮齿动物模型中促进中枢神经系统(DA)多巴胺细胞再生,并与功能恢复相关[2]。此外,GPI-1046能改善HIV相关的周围神经损伤[3]。 |
In vivo | 在治疗初期48小时后开始,GPI-1046对降低乙醇摄取表现出显著的剂量依赖性效果,该效果贯穿治疗及治疗后期。同时,水摄取量也呈剂量依赖性增加。然而,GPI-1046治疗并未影响所有动物的体重或蔗糖摄取量。值得注意的是,与所有组相比,GPI-1046(20mg/kg)在伏隔核中心(NAc-core)显著提高了GLT1水平。另外,GPI-1046(10mg/kg)相较于乙醇未接触的安慰剂组,在NAc-core提高了GLT1水平。此外,两种剂量的GPI-1046均显著提升了前额皮层(PFC)中的GLT1水平,与乙醇未接触的安慰剂组相比。GPI-1046(20mg/kg)相较于仅暴露于水和食物的未接触对照组,在PFC提高了GLT1水平。这些发现表明,神经免疫印记蛋白GPI-1046通过促进PFC和NAc-core的GLT1上调,从而部分减缓乙醇摄取[1]。 |
