1. Pathogenic Mechanisms of the Arctic Alzheimer Mutation
Sammanfattning : Alzheimer’s disease (AD) is a progressive neurodegenerative disorder, neuropathologically characterized by neurofibrillay tangles and deposition of amyloid-β (Aβ) peptides. Several mutations in the gene for amyloid precursor protein (APP) cause familial AD and affect APP processing leading to increased levels of Aβ42. LÄS MER
2. Molecular investigation of the Arctic (APP E693G) Alzheimer mutation
Sammanfattning : .... LÄS MER
3. Modeling Amyloid-β Pathology in Alzheimer’s Disease Using the Arctic Mutation
Sammanfattning : The Arctic mutation in the Amyloid-β (Aβ) domain of the Amyloid-β precursor protein (APP) causes Alzheimer’s disease (AD) and confers unique biochemical characteristics to Aβ peptides. The aims of this thesis were to evaluate a transgenic model with the Arctic mutation, and to use it to gain new insights into the mechanisms of early (pre-plaque) and late-stage Aβ pathogenesis in AD.

4. Distribution and pathophysiological role of amyloid precursor protein and presenilin 1 : characterization in rats and in vitro studies on the pathogenic arctic mutation
Sammanfattning : Alzheimer's disease is the most common form of dementia that presents a growing dilemma worldwide. Alzheimer's disease is neuropathologically characterized by cerebral atrophy accompanied by deposition of senile plaques and neurofibrillary tangles. LÄS MER
5. Characterization of the novel “Uppsala mutation” causing a familial form of early onset Alzheimer’s disease
Sammanfattning : The Alzheimer’s disease (AD) brain displays extracellular plaques of amyloid-β (Aβ), neurofibrillary tangles of tau and neuronal loss. The 40-42 amino acid Aβ peptide is formed from the amyloid precursor protein (APP) by β-secretase and γ-secretase, while α-secretase prevents Aβ generation. LÄS MER
