阿片肽作为一类重要的神经活性物质发挥着许多生物学效应,近来已有研究证明类阿片物质有影响胰岛素释放的作用。胰岛素是由胰岛β细胞分泌的一种重要激素,它可以调节机体的血糖稳定。因此这些结果将可能为糖尿病治疗开辟新天地,但其具体作用机制目前尚不清楚。本文根据国内外研究成果及最新研究进展,主要介绍了阿片肽及其受体的生理功能,阿片受体介导的信号转导以及阿片肽对胰岛素释放的调节机制。
Opioid peptide, as a kind of neuroactive peptides, has complex biological effects. Recent studies have found that β -endorphin can promote the release of insulin from the isolated dog pancreas. Opioid receptors may exist in pancreatic islet and mediate the release of insulin regulated by opioid peptide. The result may provide a new way to the treatment of diabetes mellitus, but the mechanism is still uncertain. This paper view the mechanism that opioid peptide regulate insulin release.
