The Influence Of Age, Gender, And Thiol Repletion In An In Vivo Model Of Lewy Body Disorders, Daniel Mason
The Influence Of Age, Gender, And Thiol Repletion In An In Vivo Model Of Lewy Body Disorders, Daniel Mason
Electronic Theses and Dissertations
Lewy body disorders are a family of neurological brain disorders associated with olfactory, motor, and cognitive deficits and are collectively defined as α-synucleinopathies, as they are characterized by hallmark “Lewy bodies” composed of aggregated, fibrillar α-synuclein. It is not certain but often posited that fibrillar α-synuclein seeds the progressive, self-propagating spread of Lewy pathology through neuroanatomical circuitry. Furthermore, the site of disease induction is still debated. In Aim I, we developed a novel protocol for generating reproducible and robust α-synucleinopathy in the limbic temporal lobe following infusions of preformed α-synuclein iv fibrils into the mouse olfactory bulb, which is frequently …
Structure And Thermodynamics Of Polyglutamine Peptides And Amyloid Fibrils Via Metadynamics And Molecular Dynamics Simulations, Riley Workman
Structure And Thermodynamics Of Polyglutamine Peptides And Amyloid Fibrils Via Metadynamics And Molecular Dynamics Simulations, Riley Workman
Electronic Theses and Dissertations
Aggregation of polyglutamine (polyQ)-rich polypeptides in neurons is a marker for nine neurodegenerative diseases. The molecular process responsible for the formation of polyQ fibrils is not well understood and represents a growing area of study. To enable development of treatments that could interfere with aggregation of polyQ peptides, it is crucial to understand the molecular mechanisms by which polyQ peptides aggregate into fibrils. Many experimental techniques have been employed to probe polyQ aggregation, however, observations from these studies have not lead to a unified understanding of the properties of these systems, instead yielding competing, fragmented theories of polyQ aggregation. This …
