Endocytic Vesicle Rupture In The Pathogenesis And Propagation Of Neurodegenerative Proteinopathies, William P. Flavin

Dissertations

Numerous pathological amyloid proteins spread from cell-to-cell during neurodegenerative disease, facilitating the propagation of cellular pathology and disease progression. Understanding the mechanism by which disease-associated amyloid protein assemblies enter target cells and induce cellular dysfunction is therefore key to understanding the progressive nature of such neurodegenerative proteinopathies. In this study, we utilized an imaging-based assay to monitor the ability of disease-associated amyloid assemblies to induce the rupture of intracellular vesicles following endocytosis, as well as to elucidate the cellular consequences of this damaging mechanism of invasion. We observed that the ability to induce vesicle rupture is a conserved feature of …
