Abstract
Increasing evidence highlights a tight interplay between lipid metabolism and mitochondrial homeostasis in neurons, with disruptions in either pathway amplifying cellular vulnerability. PTEN-induced kinase 1 (PINK1), a familial Parkinson's disease (PD)-related gene and a key regulator of mitochondrial quality control and homeostasis, emerges at the intersections of lipid metabolic pathways, influencing membrane composition, fatty acid utilization, and neuronal energy balance. Within this review, we discuss the role of mitochondria as hubs for lipid metabolism, the mechanisms and functional consequences of neuronal lipid handling, and the complex bidirectional relationship between lipid dysregulation and PD pathology. Special focus is given to lipid-mitochondria crosstalk and how PINK1 orchestrates this interface to maintain neuronal homeostasis. Finally, we consider therapeutic perspectives that target lipid and mitochondrial pathways, highlighting strategies to restore cellular function and PD pathology.
