This review summarizes the progression of bdEV isolation methodologies, from bulk physicochemical approaches to immunoaffinity-based, combinatorial, and single-vesicle-resolved strategies, with an emphasis on marker specificity. Using L1CAM as a representative example, we highlight how peripheral expression, extensive proteolytic cleavage, and dominance of soluble forms undermine its utility as a definitive neuronal EV marker.

Overall, current evidence indicates that no single marker can reliably define bdEV populations and that marker performance is strongly context dependent.

Such pathological changes lead to disruption of neuronal homeostasis and contribute to neuronal degeneration. During normal conditions, α-synuclein clearance is controlled by different types of lysosomal degradation, namely, macro autophagy, chaperone-mediated autophagy (CMA), micro autophagy, and the ubiquitin-proteasome system. Malfunction of these systems results in increased α-synuclein secretion due to exosome-dependent, direct, and damage-induced mechanisms, which, in turn, promotes enhanced intercellular propagation, inflammation, mitochondrial dysfunction, blood-brain barrier leakage, and neuronal cell death. Although several approaches targeting α-synuclein clearance have shown biological activity in preclinical or early clinical studies, consistent disease-modifying efficacy has not yet been established, owing to challenges including target specificity, blood brain barrier penetration, biological heterogeneity, and the limited sensitivity of clinical endpoints. Recent research indicates that successful treatment is more related to restoring the balance of these two processes than to manipulating one of them.In this review, it is proposed that a systems-level approach can be taken where PD is understood as a disease characterized by the imbalance in proteostasis. Potential treatment modalities include small molecules targeting lysosome function (ambroxol, rapamycin, TFEB activators), CMA enhancers, gene therapy, and antibodies against extracellular α-synuclein.
