Mitofusin 2 (MFN2) is a protein of the mitochondrial outer membrane that belongs to a family of highly conserved dynamin-related GTPases. It is implicated in several intracellular pathways; however, its main role is the regulation of mitochondrial dynamics, in particular mitochondrial fusion. Mutations in MFN2 are associated with Charcot–Marie–Tooth disease type 2A (CMT2A), a neurological disorder characterized by a wide spectrum of clinical features, primarily a motor sensory neuropathy. The cellular and molecular mechanisms by which MFN2 mutations lead to neuronal degeneration are largely unknown, and there is currently no cure for patients. Here, we present the most recent in vitro and in vivo models of CMT2A and the more promising therapeuticapproaches under development. These models and therapies may represent relevant tools for the study and recovery of defective mitochondrial dynamics that seem to play a significant role in the pathogenesis of other more common neurodegenerative diseases.

Abstract
Mitofusin 2 (MFN2) is a protein of the mitochondrial outer membrane that belongs to a family of highly conserved dynamin-related GTPases. It is implicated in several intracellular pathways; however, its main role is the regulation of mitochondrial dynamics, in particular mitochondrial fusion. Mutations in MFN2 are associated with Charcot–Marie–Tooth disease type 2A (CMT2A), a neurological disorder characterized by a wide spectrum of clinical features, primarily a motor sensory neuropathy. The cellular and molecular mechanisms by which MFN2 mutations lead to neuronal degeneration are largely unknown, and there is currently no cure for patients. Here, we present the most recent in vitro and in vivo models of CMT2A and the more promising therapeuticapproaches under development. These models and therapies may represent relevant tools for the study and recovery of defective mitochondrial dynamics that seem to play a significant role in the pathogenesis of other more common neurodegenerative diseases.File | Dimensione | Formato | |
