1. 1. The amyloid-β precursor protein (APP) and its adaptor protein Fe65 : Two key players in Alzheimer’s disease

   Författare :Preeti Menon; Anna-Lena Ström; Thorsten Müller; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer s disease; APP; Fe65; Meprinβ; α-secretase; APP processing; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

   Sammanfattning : Alzheimer’s disease (AD) is a neurodegenerative disease characterized by the abnormal accumulation and aggregation of amyloid beta (Aβ) peptides within the brain. Generation of Aβ occur when the amyloid-beta precursor protein (APP) is proteolytically processed by β- and then γ-secretase in the amyloidogenic pathway. LÄS MER

3. 2. α-Secretase processing of the Alzheimer amyloid-β precursor protein and its homolog APLP2

   Författare :Kristin Jacobsen; Kerstin Iverfeldt; Olav Andersen; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; APP; APLP2; ADAM10; TACE; Alzheimer s Disease; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

   Sammanfattning : The amyloid-β precursor protein (APP) has been widely studied due to its role in Alzheimer´s disease (AD). When APP is sequentially cleaved by β- and γ-secretase, amyloid-β (Aβ) is formed. Aβ is prone to aggregate and is toxic to neurons. LÄS MER

4. 3. Processing of the APP family by the α-secretases ADAM10 and TACE

   Författare :Kristin Jacobsen; Kerstin Iverfeldt; Lars Nilsson; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurochemistry; Neurokemi; Neurochemistry and Molecular Neurobiology; neurokemi med molekylär neurobiologi;

   Sammanfattning : Alzheimer’s disease (AD) is a progressive neurodegenerative disease, which is characterized by formation of amyloid plaques in the brain. The major constituent of these plaques is the hydrophobic peptide Aβ. Aβ accumulation is considered to be the main cause of the pathology seen in AD brains. LÄS MER

5. 4. Pathogenic Mechanisms of the Arctic Alzheimer Mutation

   Författare :Charlotte Sahlin; Lars Lannfelt; Lars Nilsson; Christian Haass; Uppsala universitet; []
   Nyckelord :Neurosciences; Alzheimer s disease; Arctic mutation; Amyloid precursor protein; Amyloid-β; APP processing; Aβ oligomers; Docosahexaenoic acid; Neurovetenskap;

   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

7. 5. Proteolytic processing of the Alzheimer APP protein family during neuronal differentiation

   Författare :Sofia Holback; Kerstin Iverfeldt; Nigel Hooper; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; APP; APLP1; APLP2; differentiation; processing; retinoic acid; secretase; Neurochemistry; Neurokemi; Neurochemistry and Molecular Neurobiology; neurokemi med molekylär neurobiologi;

   Sammanfattning : Increased amyloid-β (Aβ) load in the brain, neurite degeneration, neuronal loss, and decreased levels of several neurotrophins are among the characteristics of Alzheimer’s disease (AD). Generation of Aβ occurs when the amyloid precursor protein (APP) is proteolytically processed by β- and γ-secretases in the amyloidogenic pathway. LÄS MER
