多种动物脑内有高水平的胰岛素,而且神经元和胶质细胞上均存在胰岛素受体和胰岛素第二信使系统。
Insulin can be found at high level in the brain of some animals. Insulin receptors and insulin second messengers systems are present in neurons and glial cells.
Sometimes second messengers collect signals from a variety of different receptor systems, translate them into one kind of internal change, and the cell then just has to know about that one thing changing.
第二信使分子能够收集,来自不同受体系统的信号,将它们转化为同一种细胞内在的变化,这样细胞就只需对一种变化作出反应
