The Role Of Apolipoprotein E In Regulating Tau Pathogenesis And Neurodegeneration In A Tauopathy Mouse Model, Yang Shi
Arts & Sciences Electronic Theses and Dissertations
APOE4 is the strongest genetic risk factor for late-onset Alzheimer's disease (AD). APOE4 increases brain amyloid-β (Aβ) pathology relative to other APOE isoforms. However, whether APOE independently influences tau pathology, the other pathological hallmark of AD and other tauopathies, or tau-mediated neurodegeneration, is not clear. By generating P301S tau transgenic mice on either a human APOE knock in (KI) or APOE knockout (KO) background, we show that the presence of human APOE, regardless of APOE isoforms, leads to various degrees of brain atrophy in 9-month old P301S mice, whereas APOE ablation strongly protects against neurodegeneration. In particular, P301S/E4 mice develop …

Cyclophilin 40 As A Novel Disaggregase, Jeremy Dustin Baker
USF Tampa Graduate Theses and Dissertations
The negative health and economic impacts of neurodegenerative diseases on Americans is astounding and accelerating with an aging population. The Alzheimer’s Association reports that 5.7 million Americans suffer from Alzheimer’s disease (AD), a number which is expected to increase to 14 million by 2050. In economic terms, AD and other neurodegenerative disorders will cost the US over $275 billion in 2018, rising to over $1 trillion annually by 2050. AD causes gross brain atrophy and is most damaging throughout the cortex and the hippocampus, regions required for higher cognitive function and memory. AD presents as tangles within neurons composed of …

Background: Down syndrome (DS) individuals, by the age of 40s, are at increased risk to develop Alzheimer-like dementia, with deposition in brain of senile plaques and neurofibrillary tangles. Our laboratory recently demonstrated the disturbance of PI3K/AKT/mTOR axis in DS brain, prior and after the development of Alzheimer Disease (AD). The aberrant modulation of the mTOR signalling in DS and AD age-related cognitive decline affects crucial neuronal pathways, including insulin signaling and autophagy, involved in pathology onset and progression. Within this context, the therapeutic use of mTOR-inhibitors may prevent/attenuate the neurodegenerative phenomena. By our work we aimed to rescue mTOR signalling …
