ASU Electronic Theses and Dissertations

This collection includes most of the ASU Theses and Dissertations from 2011 to present. ASU Theses and Dissertations are available in downloadable PDF format; however, a small percentage of items are under embargo. Information about the dissertations/theses includes degree information, committee members, an abstract, supporting data or media.

In addition to the electronic theses found in the ASU Digital Repository, ASU Theses and Dissertations can be found in the ASU Library Catalog.

Dissertations and Theses granted by Arizona State University are archived and made available through a joint effort of the ASU Graduate College and the ASU Libraries.

Alzheimer's Disease (AD) is a progressive neurodegenerative disease accounting for 50-80% of dementia cases in the country. This disease is characterized by the deposition of extracellular plaques occurring in regions of the brain important for cognitive function. A primary component of these plaques is the amyloid-beta protein. While a natively unfolded protein, amyloid-beta can misfold and aggregate generating a variety of different species including numerous different soluble oligomeric species some of which are precursors to the neurofibrillary plaques. Various of the soluble amyloid-beta oligomeric species have been shown to be toxic to cells and their presence may correlate with progression …

The pathophysiology of neurodegenerative diseases, such as Alzheimer’s disease (AD), remain difficult to ascertain in part because animal models fail to fully recapitulate the complex pathophysiology of these diseases. In vitro models of neurodegenerative diseases generated with patient derived human induced pluripotent stem cells (hiPSCs) and human embryonic stem cells (hESCs) could provide new insight into disease mechanisms. Although protocols to differentiate hiPSCs and hESCs to neurons have been established, standard practice relies on two dimensional (2D) cell culture systems, which do not accurately mimic the complexity and architecture of the in vivo brain microenvironment. I have developed protocols to …
