Ruiz-Ortega 1,3*†, Anna Wil kaniec 1†, Josué Juárez2 and Agata Adamczyk 1*  \nAbstract  \nParkinson’s disease (PD) is defined by the progressive loss of dopaminergic neurons and the accumulation of misfolded α-synuclein (α-syn), yet the molecular determinants of selective neuronal vulnerability remain unresolved. Increasing evidence implicates mitochondria—and particularly their membranes—as critical platforms where α-syn is toxic. This review highlights how α-syn engages mitochondrial membranes through two interconnected processes: classical aggregation and liquid‒liquid phase separation. Both pathways disrupt membrane architecture, compromise respiratory chain function, and impair mitophagy. A pivotal mediator of these events is cardiolipin (CL), a mitochondria-specific phospholipid essential for cristae organization and quality control pathways. Despite extensive progress, the precise mechanistic contributions of CL to α-syn aggregation, phase transitions, and neuronal degeneration remain poorly defined. Clarifying this interplay is crucial, as CL not only binds α-syn with high affinity but also determines whether it remains in a functional state or progresses toward toxic assemblies. By integrating recent advances, we propose a unifying perspective on CL as a molecular switch at the crossroads of mitochondrial biology, protein aggregation, and phase behavior. Beyond mechanistic insight, this view underscores the potential of CL as a target for the development of mitochondria-directed therapies in PD.  \nKeywords Parkinson’s disease, Alpha-synuclein, Mitochondrial dysfunction, Cardiolipin, Liquid‒liquid phase separation  \n†Eva D.

Each disorder arises from the misfolding and aggregation of distinct proteins within the central nervous system (CNS), resulting in distinctive molecular signatures and neuropathological features that enable their classification [39, 82, 223, 282]. Among these conditions, PD stands out as the second most common neurodegenerative disorder worldwide [51, 125, 211], and a major health challenge in aging populations [150], with  \n© The Author(s) 2025.
