CCK-8S对野生型小鼠和AD模型小鼠的突触发育的影响及作用机制
发布时间:2022-01-14 20:16
目的:1研究野生型小鼠和阿尔茨海默氏症(Alzheimer’s Disease, AD)模型小鼠的体外培养海马神经元的突触发育过程中,硫化八肽缩胆囊素(sulfated cholecystokinin octapeptide,CCK-8S)对神经元树突丝、树突棘发育的影响。2研究CCK-8S是否通过CCKⅡ型受体(Cholecystokinin-2type receptors, CCK-2R)介导的途径影响神经元突触发育。3探寻CCK-8S在海马神经元发育过程中的作用和作用机制,为阿尔茨海默病的发病机理研究提供新实验依据。方法:新生第一天AD模型(APP/PS1转基因)小鼠和野生型小鼠经PCR鉴定后,分别对其进行海马取材,体外培养神经元。从体外培养第2天(DIV1)开始,用药物进行处理,分为四组:空白对照组、CCK-8S(0.2μM)处理组、CI988(0.1μM)、CCK-8S(0.2μM)&CI988(0.1μM)共处理组,一直培养到第21天(DIV21)。选取三个时间点进行观察研究,分别为DIV7、DIV14、DIV21,每次观察前,提前24h用绿色荧光蛋白启动子腺病毒(...

AD模型小鼠与野生型小鼠的PCR鉴定
在DIV7,AD模型小鼠神经元的树突丝、树突棘密度与野生型小鼠相比较显著减少,CCK-8S处理引起神经元树突丝、树突棘密度增加,CI988阻断CCK-8S增加树突丝、树突棘密度的作用(A-F)为野生型小鼠(A-C)和AD模型小鼠(D-E)DIV7的海马神经元成像,(A,D)为对照组,(B,E)为CCK-8S(0.2μM)处理组,(C,F)为CCK-8S(0.2μM)&CI988(0.1μM)共处理组
在DIV21,AD模型小鼠神经元的树突丝、树突棘密度与野生型小鼠相比较显著减少,CCK-8S处理引起树突丝、树突棘密度增加,CI988阻断CCK-8S增加树突丝、树突棘密度的作用(A-F)为野生型小鼠海马神经元(A-C)和AD模型小鼠海马神经元(D-F),在DIV21的细胞成像,标尺=20μm和5μm
