中文摘要
我们正在研究神经毒性四氢异喹啉(TIQ)衍生物的多种功能。在本研究中,我们研究了TIQ衍生物对转运蛋白如P-糖蛋白(P-gp)的影响。部分TIQ衍生物可被P-gp识别并从脑内排出。对P-gp抑制小鼠给予TIQ衍生物可促进帕金森病。TIQ衍生物处理也改变了P-gp的表达水平:P-gp表达短暂升高,然后下降。因此,P-gp功能障碍是帕金森病诱发因素的候选者。
英文摘要
We are investigating multiple functions of neurotoxic tetrahydroisoquinoline (TIQ) derivatives. In the present study, we examined the effects of TIQ derivatives on transporters such as P-glycoprotein (P-gp). Some of TIQ derivatives were recognized by P-gp and evacuated from the brain. The administration of TIQ derivatives to P-gp -inhibited mice promoted parkinsonism. Treatment of TIQ derivatives also change the expression level of P-gp : P-gp expression transiently went up, and then decreased. Thus, malfunction of P-gp is a candidate of Parkinson's disease-inducing factors.
