关于运动、认知和载脂蛋白 E (APOE) 基因型的人体研究表明,ε4 携带者可能受益于定期的体力活动。我们检查了 10-12 个月大的 APOE ε3 和 APOE ε4 转基因小鼠的自主跑轮、记忆力和海马可塑性。久坐的 ε4 小鼠在径向臂水迷宫(RAWM)中表现出认知缺陷,这是一项依赖于海马体的任务。 ε4 小鼠进行六周的轮跑后,RAWM 改善至 ε3 小鼠的水平。 ε3 和 ε4 小鼠的海马脑源性神经营养因子 (BDNF) 水平相似,并且运动后 ε3 和 ε4 小鼠的海马脑源性神经营养因子 (BDNF) 水平相似地增加。在久坐的 ε4 小鼠中,酪氨酸激酶 B (Trk B) 受体减少了 50%。运动使 ε4 小鼠的 Trk B 恢复到 ε3 小鼠的水平,而在 ε4 小鼠中,运动显着增加了突触素(突触功能的标志物)。我们的结果支持这样的假设:运动可以改善认知功能,尤其是 ε4 携带者。
Human studies on exercise, cognition, and apolipoprotein E (APOE) genotype show that ε4 carriers may benefit from regular physical activity. We examined voluntary wheel-running, memory, and hippocampal plasticity in APOE ε3 and APOE ε4 transgenic mice at 10–12 months of age. Sedentary ε4 mice exhibited deficits in cognition on the radial-arm water maze (RAWM), a task dependent on the hippocampus. Six weeks of wheel-running in ε4 mice resulted in improvements on the RAWM to the level of ε3 mice. Hippocampal brain-derived neurotrophic factor (BDNF) levels were similar in ε3 and ε4 mice, and after exercise BDNF was similarly increased in both ε3 and ε4 mice. In sedentary ε4 mice, tyrosine kinase B (Trk B) receptors were reduced by 50%. Exercise restored Trk B in ε4 mice to the level of ε3 mice, and in ε4 mice, exercise dramatically increased synaptophysin, a marker of synaptic function. Our results support the hypothesis that exercise can improve cognitive function, particularly in ε4 carriers.
