摘要
胰高血糖素样肽1 (glucagon-like peptide 1, GLP-1)是一种在回肠肠内分泌l细胞和脑孤束核(NTS)神经元中产生的具有多种代谢作用的激素。GLP-1R在认知功能中的核心作用是众所周知的。相反,已经证明运动对大脑功能有积极的影响。因此,我们决定阐明GLP-1是否在记忆和学习中起作用。实验选用32只大鼠,分为4组。麻醉大鼠后,检测右侧脑室,并将导管插入脑室。各组按10微克exendin-3或无菌生理盐水,每日1次经ICV注射,连续7天。运动组大鼠每天运动1小时(每分钟17米),连续7天。采用标准莫里斯水迷宫(Morris water maze, MWM)水箱评价大鼠的记忆和学习能力。结果显示,TE-exendin组与TE-SAL组在潜伏期和区域内时间参数上均有统计学差异。综上所述,GLP-1R在运动组中改善了记忆和学习,而在久坐组中没有改善,我们可以假设运动可以通过这一途径影响记忆和学习。
Exercise Improves Spatial Learning and Memory Performance through the Central GLP-1 Receptors.
The glucagon-like peptide 1 (GLP-1) is a hormone which is produced in the enteroendocrine L-cells in the ileum and the neurons of nucleus tractus solitarius (NTS) in the brain which has numerous metabolic effects. The central GLP-1R's role in cognitive functioning is well known. On the contrary, it has been shown that exercise has positive effects on brain function. So, we decided to elucidate whether the central GLP-1 has a role in memory and learning. Thirty-two rats were used in this experiment in 4 groups. After anesthetizing the rats, the right lateral ventricle was detected, and a cannula was directed to the ventricle. Ten micrograms of exendin-3 or sterile saline, according to the group, was injected via ICV once daily for seven days. The rats in the exercise group considered an exercise period of one hour each day (17 meters per minute) for seven consecutive days. To evaluate the performance of memory and learning, a standard Morris water maze (MWM) tank was utilized. According to the results, the TE-exendin group showed a statistically significant difference from the TE-SAL group in both parameters of latency and time in the zone. In summary, memory and learning were improved by GLP-1R in the exercise group, but not in the sedentary group, which we can hypothesize that exercise can affect memory and learning through this pathway.
