最近对胰岛素作用机理的研究指出,胰岛素与它的靶细胞受体结合后,激活细胞膜上的蛋白水解酶,或磷脂酶C而导致膜上某种糖蛋白或磷脂水解,产生多肽样或磷脂样的化学介体。它们能在无细胞系统中模拟胰岛素的各种作用,如,调节胰岛素敏感的酶的活性,以及在完整细胞中模拟胰岛素的一些生物功能,包括调节cAMP水平、腺苷酸环化酶活性、抗 Recent studies on the mechanism of action of insulin indicate that the binding of insulin to its target cell receptor activates the proteolytic enzyme, or phospholipase C, on the cell membrane, resulting in the hydrolysis of certain glycoproteins or phospholipids on the membrane, producing polypeptide-like or phospholipid-like Chemical mediator. They mimic the various effects of insulin in cell-free systems, such as regulating insulin-sensitive enzyme activity and mimicking some of the biological functions of insulin in intact cells, including regulation of cAMP levels, adenylyl cyclase activity, resistance
