ABSTRACT=Neurodegenerative diseases are a category of neurological conditions with high prevalence that pose major treatment challenges. Common pathologies involve protein accumulation and mitochondrial damage. Mitophagy maintains cellular homeostasis by removing defective mitochondria, which are associated with the pathogenesis of neurodegenerative diseases. Although the ubiquitin-dependent mitophagy mediated by the PINK1–Parkin pathway has been extensively studied, growing evidence indicates that receptor-mediated mitophagy plays a crucial compensatory role in neurons, particularly when the PINK1–Parkin pathway is impaired. This review focuses on the emerging field of receptor-mediated mitophagy, systematically elaborating its role as a key homeostatic mechanism operating independently of the canonical PINK1/Parkin pathway. It provides a focused analysis of the specific functions and activation mechanisms of key receptors—including BNIP3, NIX, FUNDC1, and AMBRA1—in models of Alzheimer’s disease, Parkinson’s disease, and amyotrophic lateral sclerosis. Furthermore, this review explores the clinical potential of targeting these specific receptors for precise intervention, aiming to provide a new theoretical foundation and direction for developing therapeutic strategies against neurodegenerative diseases.
