摘要

生长激素通过刺激生长激素受体(GHR)释放胰岛素样生长因子-1 (IGF-1)介导其大部分作用,特别是在肝脏中。生长激素和IGF-1都能穿过血脑屏障(BBB),影响大脑中这些激素的特定目标。中枢神经系统中GH和IGF-1受体的发现及其在大脑区域的分布与生长营养轴(GH/IGF-1轴)激活引起的行为效应的功能解剖相关,为这两种激素有益作用的机制提供了新的视角。

Editorial - Current Knowledge on Growth Hormone and Insulin-Like GrowthFactors and their Role in the Central Nervous System
GH mediates most of its effects by releasing insulin-like growth factor-1 (IGF-1) through stimulation of GH receptors (GHR), in particular in the liver. Both GH and IGF-1 are shown to cross the blood-brain barrier (BBB) and affect specific targets for these hormones in the brain. The discovery of GH and IGF-1 receptors in the CNS and their distribution in brain areas associated with the functional anatomy of behavioral effects induced by activation of the somatotrophic axis (GH/IGF-1 axis) has brought up new aspects on the mechanisms underlying beneficial effects seen for the two hormones.
