摘要
近年来的研究显示,胰岛素样生长因子-1(IGF-1)与学习记忆密切相关;运动可以使海马内的IGF-1水平升高;IGF-1可能介导运动促进学习记忆的过程,其机制之一可能是IGF-1和脑源性神经营养因子(BDNF)信号通路对Ca2+/钙调蛋白依赖性蛋白激酶Ⅱ(CAMKⅡ)、丝裂原活化蛋白激酶Ⅱ(MAPKⅡ)和突触素-1起调节作用,它们共同调节突触的可塑性,进而提高学习记忆能力。
Recent study demonstrated that insulin-like growth factor 1 (IGF- 1) could have benefits to improve the learning memory. Exercise can increase IGF-1 level in hippocampus. IGF-1 may mediate exercise inducing learning memory; one of the possible mechanism is that the IGF-1 and brain derived neurotrophic factor (BDNF) has a common regulatory capacity over calcium/calmodulin-dependent protein kinase Ⅱ (CAMK Ⅱ ), mitogen activated protein kinase Ⅱ (MAPK Ⅱ ) and synapsin-1 ,and the convergence of multiple signaling pathways mediate synaptic plasticity and improve learning memory.
