摘要

Mitochondria are essential for neuronal energy production, cellular homeostasis, and overall neuronal function. Due to their high metabolic demands and limited regenerative capacity, neurons are particularly vulnerable to mitochondrial dysfunction, which leads to ATP depletion, excessive reactive oxygen species (ROS) production, and calcium imbalance—ultimately causing oxidative stress, metabolic disruption, and neuronal death. Mitophagy is a selective process that removes damaged mitochondria through the autophagy-lysosome pathway. As a key mechanism of mitochondrial quality control, mitophagy preserves energy production, limits oxidative damage, and maintains mitochondrial network integrity. This process is regulated by pathways such as PINK1-Parkin and receptor-mediated mechanisms involving BNIP3 and FUNDC1, all of which help sustain cellular health by preventing mitochondrial dysfunction. Impaired mitophagy is a common feature of several neurodegenerative diseases, including Alzheimer’s, Parkinson’s, amyotrophic lateral sclerosis (ALS), and Huntington’s disease, exacerbating mitochondrial damage and neuronal stress. Emerging therapeutic strategies that target mitophagy—ranging from pharmacological agents and gene therapies to dietary interventions—show promise in restoring mitochondrial quality and protecting neurons from degeneration. Nevertheless, challenges remain in translating these findings into effective clinical treatments. Mitophagy represents a critical mechanism for preserving neuronal integrity and offers a compelling target for innovative therapies against neurodegenerative disorders.
