Alzheimer's And Amyloid Beta: Amyloidogenicity And Tauopathy Via Dyshomeostatic Interactions Of Amyloid Beta, Jordan Tillinghast
Alzheimer's And Amyloid Beta: Amyloidogenicity And Tauopathy Via Dyshomeostatic Interactions Of Amyloid Beta, Jordan Tillinghast
Senior Honors Theses
This paper reviews functions of Amyloid-β (Aβ) in healthy individuals compared to the consequences of aberrant Aβ in Alzheimer’s disease (AD). As extraneuronal Aβ accumulation and plaque formation are characteristics of AD, it is reasonable to infer a pivotal role for Aβ in AD pathogenesis. Establishing progress of the disease as well as the mechanism of neurodegeneration from AD have proven difficult (Selkoe, 1994). This thesis provides evidence suggesting the pathogenesis of AD is due to dysfunctional neuronal processes involving Aβ’s synaptic malfunction, abnormal interaction with tau, and disruption of neuronal homeostasis. Significant evidence demonstrates that AD symptoms are partially …
The Master Synaptic Regulator: Activity Regulated Cytoskeleton Associated Protein, Arc, In Normal Aging And Diseases With Cognitive Impairment, Amber Khan
Dissertations, Theses, and Capstone Projects
Alzheimer’s disease (AD) is a progressive neurodegenerative disease with complex underlying pathogenic mechanisms. Epidemiological studies have forecasted that in the next 3 decades, the number of AD cases will rise to epidemic proportions with enormous medical, emotional and financial burdens impacting individuals affected and society. Among many risk factors for AD, advancing age is clearly essential and necessary. Revelation of molecular changes in synaptic activities leading to the prodromal, mild cognitive impairment (MCI) stage may help illuminate the course of pathogenic progression and its cause-effect relationship with various targets thereby enabling target-driven disease-modifying therapeutic agents for AD.

Green Tea Extract, Epigallocatechin Gallate, Protect Against Methamphetamine-Induced Striatal Neurotoxicity In Mice, Allen L. Pan
Dissertations, Theses, and Capstone Projects
Methamphetamine (METH) is a strong psychostimulant and its exposure can lead to serious neurological complications. METH-induced neuronal injury is the result of a complex interplay of different factors including dopamine (DA) overflow, oxidative stress and neuroinflammation. Although the mechanisms of METH-induced neurotoxicity have been extensively studied, there is still no effective therapeutic treatment. Therefore, it is essential to study potential drug candidates that can treat METH-induced neurotoxicity. Green tea extract, epigallocatechin gallate (EGCG), has emerged as a neuroprotective agent that can protect against several neurodegenerative diseases such as Alzheimer’s and Parkinson’s diseases. Recently, our lab has shown that EGCG prevents …
Investigating The Role Of Neuronal Aging In Fragile X-Associated Tremor/Ataxia Syndrome, Katlin Marie Hencak
Investigating The Role Of Neuronal Aging In Fragile X-Associated Tremor/Ataxia Syndrome, Katlin Marie Hencak
Honors Undergraduate Theses
Fragile X-associated tremor/ataxia syndrome (FXTAS) is an X-linked late-onset neurodegenerative disorder caused by a noncoding trinucleotide repeat expansion in the FMR1 gene. This gene produces fragile x mental retardation protein (FMRP), an RNA binding protein whose targets are involved in brain development and synaptic plasticity. One of the proposed mechanisms of FXTAS pathogenesis is an RNA gain-of-function in which the repeat expansion causes toxic mRNA that sequesters important proteins in the cell, interfering with their functions. Another suggested method of pathogenesis is through a mutant protein called FMRpolyG. This protein results from repeat-associated non-AUG (RAN) translation, in which the expanded …
Autologous Peripheral Nerve Grafts To The Brain For The Treatment Of Parkinson's Disease, Andrew Welleford
Autologous Peripheral Nerve Grafts To The Brain For The Treatment Of Parkinson's Disease, Andrew Welleford
Theses and Dissertations--Neuroscience
Parkinson’s disease (PD) is a disorder of the nervous system that causes problems with movement (motor symptoms) as well as other problems such as mood disorders, cognitive changes, sleep disorders, constipation, pain, and other non-motor symptoms. The severity of PD symptoms worsens over time as the disease progresses, and while there are treatments for the motor and some non-motor symptoms there is no known cure for PD. Thus there is a high demand for therapies to slow the progressive neurodegeneration observed in PD. Two clinical trials at the University of Kentucky College of Medicine (NCT02369003, NCT01833364) are currently underway that …
Role Of Sarm1 In Chronic Immune-Mediated Central Nervous System Inflammation, Kenneth E. Viar Ii
Role Of Sarm1 In Chronic Immune-Mediated Central Nervous System Inflammation, Kenneth E. Viar Ii
Theses and Dissertations
SARM1 is an injury-induced nicotinamide adenine dinucleotide nucleosidase (NADase) that was previously shown to promote axonal degeneration in response to traumatic, toxic, and excitotoxic stressors. This raises the question of whether a SARM1-dependent program of axonal degeneration is central to a common pathway contributing to disease burden in neurological disorders. The degree to and mechanism by which SARM1 inactivation decreases the pathophysiology of such disorders is of interest to establish the rationale to pursue SARM1 as a therapeutic target. In this study, we compare the course and pathology of experimental autoimmune encephalomyelitis (EAE) in Sarm1-knockout (KO) mice and wild-type …
