Histones facilitate α-synuclein aggregation during neuronal apoptosis.

ABSTRACT: Ample in vitro and in vivo experimental evidence supports the hypothesis that intercellular transmission of α-synuclein (αS) is a mechanism underlying the spread of αS pathology in Parkinson's disease and related disorders. What remains unexplained is where and how initial transmissible αS aggregates form. In a previous study, we demonstrated that αS aggregates rapidly form in neurons with impaired nuclear membrane integrity due to the interaction between nuclear proaggregant factor(s) and αS and that such aggregates may serve as a source for αS seeding. In the present study, we identify histones as a potential nuclear proaggregant factor for αS aggregation in both apoptotic neurons and brains with αS pathology. We further demonstrate that histone-induced aggregates contain a range of αS o
