Barrett, The Honors College Thesis/Creative Project Collection
Barrett, The Honors College at Arizona State University proudly showcases the work of undergraduate honors students by sharing this collection exclusively with the ASU community.
Barrett accepts high performing, academically engaged undergraduate students and works with them in collaboration with all of the other academic units at Arizona State University. All Barrett students complete a thesis or creative project which is an opportunity to explore an intellectual interest and produce an original piece of scholarly research. The thesis or creative project is supervised and defended in front of a faculty committee. Students are able to engage with professors who are nationally recognized in their fields and committed to working with honors students. Completing a Barrett thesis or creative project is an opportunity for undergraduate honors students to contribute to the ASU academic community in a meaningful way.

Fluorescence microscopy of TSPO transfected HEK cell cultures labeled with Carboxy-H2DCFDA and treated with Beta Amyloid (Aβ) and α-synuclein (α-syn) resulted in DAPI fluorescing Human Embryonic Kidney (HEK) nuclei in blue and Green Fluorescent Protein (GFP) fluorescing reactive oxygen species (ROS) or oxidative stress in cell cytoplasm in green. Preliminary study suggests TSPO transfected cells may be used to test oxidative stress with disease pathological elements (Aβ and α-synuclein). In IHC, TSPO immunoreactivity was observed in IBA1 and LN3 marked microglia with varying degrees of expression. Beaded structures were also observed with TSPO immunoreactivities, possibly representing microglia processes. TSPO immunoreactivity was observed in and surrounding amyloid plaques and p-tau immunoreactive neurites. This demonstrates that TSPO is predominantly expressed in microglia and are closely associated with Alzheimer’s disease pathological elements, suggesting involvement of TSPO-expressing microglia in neurodegenerative processes.
Alzheimer’s disease (AD) is a devastating disorder that affects the lives of both patients and their loved ones. While it is believed that AD is due to a buildup of amyloid plaques in the brain that eventually lead to the formation of neurofibrillary tangles (NFTs) and result in neurodegeneration, there are many theories that attempt to define the causes of AD. This paper investigates the amyloid and tau theories in more detail, including how these proteins can spread in the brain. It will also take a look into other potential theories that could contribute to AD symptoms such as vascular issues or neuroinflammation. Frontotemporal dementia (FTD) is another form of dementia, albeit much rarer than AD, that is typically characterized by symptoms that follow the opposite progression of AD: behavior and judgement are affected before memory. In addition, FTD is closely related to amyotrophic lateral sclerosis (ALS), a movement disorder that is caused by a loss of motor neurons that results in loss of muscle control. This paper will also examine how FTD and ALS are related, as well as theories behind the potential causes of these disorders. Finally, this paper will examine a patient who exhibits signs and symptoms of both disorders to attempt to determine the potential diagnosis.
