摘要
Dynamic change of mitochondrial morphology and distribution along neuronal branches are essential for neural circuitry formation and synaptic efficacy.However,the underlying mechanism remains elusive.We show here that Pink1 knockout(KO)mice display defective dendritic spine maturation,reduced axonal synaptic vesicles,abnormal synaptic connection,and attenuated long-term synaptic potentiation(LTP).Drp1 activation via ^(S616) phosphorylation rescues deficits of spine maturation in Pink1 KO neurons.
