一、胰岛素样生长因子 1(insulin- L ike growth factor- 1,IGF- 1)及其受体在中枢神经系统 (CNS)中的分布IGF- 1是一种含 70个氨基酸的多肽 ,分子量 11KD。它在脑组织有广泛的分布 ,且不同区域的含量不尽相同。Yam -aguchi等 [1 ]用放免法测得成年 SD大鼠 8个脑区组织内IGF- 1
First, the distribution of insulin-like growth factor-1 (IGF-1) and its receptors in the central nervous system (CNS) IGF-1 is a 70 amino acid polypeptide with a molecular weight of 11KD . It has a wide range of brain tissue distribution, and the content of different regions vary. Yam -aguchi et al [1] measured by radioimmunoassay 8 adult SD rat brain tissue IGF- 1
