主 题:Parkinson's disease neurogenesis neurodegeneration mitochondria non-human primates
摘 要:In vitro studies have established the prevalent theory that the mitochondrial kinase PINK1 protects neurodegeneration by removing damaged mitochondria in Parkinson s disease(PD).However,difficulty in detecting endogenous PINK1 protein in rodent brains and cell lines has prevented the rigorous investigation of the in vivo role of *** we report that PINK1 kinase form is selectively expressed in the human and monkey ***/Cas9-mediated deficiency of PINK1 causes similar neurodegeneration in the brains of fetal and adult monkeys as well as cultured monkey neurons without affecting mitochondrial protein expression and ***,PINK1 mutations in the primate brain and human cells reduce protein phosphorylation that is important for neuronal function and *** findings suggest that PINK1 kinase activity rather than its mitochondrial function is essential for the neuronal survival in the primate brains and that its kinase dysfunction could be involved in the pathogenesis of PD.
