Abstract

The selective disruption of certain cell types — notably neurons — in diseases involving mitochondrial dysfunction is thought to reflect the high-energy requirements of these cells, but few details are known. Recent studies have provided clues to the cellular basis of this mitochondrial requirement. Mitochondria are regionally organized within some nerve cells, with higher accumulations in the soma, the hillock, the nodes of Ranvier and the nerve terminal. In the synaptic region, mitochondria regulate calcium and ATP levels, thereby maintaining synaptic transmission and structure. Defects in mitochondrial dynamics can cause deficits in mitochondrial respiration, morphology and motility. Moreover, mutations in the mitochondrial fusion genes Mitofusin-2 and OPA1 lead to the peripheral neuropathy Charcot-Marie-Tooth type 2A and dominant optic atrophy. Perhaps it is the strict spatial and functional requirements for mitochondria in neurons that cause defects in mitochondrial fusion to manifest primarily as neurodegenerative diseases.
