线粒体是细胞ATP生成器。它们是经历裂变和融合的动态结构。虽然对线粒体裂变机制了解很多,但启动裂变的机制以及裂变对神经生理学的意义在很大程度上尚不清楚。伽马振荡是同步的神经活动,对突触施加巨大的能量挑战。伽马振荡的细胞机制尚未被定义。在这里,我们表明,dysbindin-1是精神分裂症患者大脑中减少的一种蛋白质,它通过促进Drp 1寡聚化而为神经活动诱导的裂变所需。这个过程是从事伽马频率活动,反过来,支持伽马振荡。在dysbindin-1缺失小鼠中,γ振荡和新物体识别受损。这些缺陷可以通过增加线粒体分裂来改善。这些发现确定了活动诱导的线粒体裂变的分子机制,线粒体裂变在伽马振荡中的作用,以及线粒体裂变作为改善认知功能的潜在目标。
Mitochondria are cellular ATP generators. They are dynamic structures undergoing fission and fusion. While much is known about the mitochondrial fission machinery, the mechanism of initiating fission and the significance of fission to neurophysiology are largely unclear. Gamma oscillations are synchronized neural activities that impose a great energy challenge to synapses. The cellular mechanism of fueling gamma oscillations has yet to be defined. Here, we show that dysbindin-1, a protein decreased in the brain of individuals with schizophrenia, is required for neural activity-induced fission by promoting Drp1 oligomerization. This process is engaged by gamma-frequency activities and in turn, supports gamma oscillations. Gamma oscillations and novel object recognition are impaired in dysbindin-1 null mice. These defects can be ameliorated by increasing mitochondrial fission. These findings identify a molecular mechanism for activity-induced mitochondrial fission, a role of mitochondrial fission in gamma oscillations, and mitochondrial fission as a potential target for improving cognitive functions.
