Abstract
Mitochondria are energy-producing organelles, and neurons are high energy consumption cells. Therefore, mitochondrial dysfunction is a critical factor in neurodegenerative processes. Mitochondrial division inhibitor-1 (Mdivi-1) is a small chemical inhibitor of mitochondrial division dynamin, which plays multiple roles in mitochondrial dynamics, mitochondrial autophagy, ATP production, the immune response, and Ca²⁺ homeostasis. Mdivi-1 inhibition of excessive mitochondrial fission exerted cytoprotective effects in neurodegenerative diseases, such as Alzheimer's disease (AD), Parkinson's disease (PD), and multiple sclerosis (MS). Mdivi-1 changed the mRNA expression of the electron transport chain (ETC) and reduced Ca²⁺ overload against neuronal injury. Elucidation of the molecular mechanism of Mdivi-1 in neurodegenerative diseases will help evaluate its therapeutic potential and promote its application in clinical studies. The present article focused on the multiple effects of Mdivi-1 on mitochondrial function and its potential therapeutic effects in neurodegenerative diseases.
