  1. 1. Proislet Amyloid Polypeptide (proIAPP) : Impaired Processing is an Important Factor in Early Amyloidogenesis in Type 2 Diabetes

    Författare :Johan F. Paulsson; Gunilla Westermark; Christer Betsholtz; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biosynthesis amyloid; Genetics amyloid; Metabolism amyloid; Islets of Langerhans; Proprotein convertases; Posttranslation protein processing; Medical cell biology; Medicinsk cellbiologi;

    Sammanfattning : Amyloid is defined as extracellular protein aggregates with a characteristic fibrillar ultra-structure, Congo red affinity and a unique x-ray diffraction pattern. At present, 25 different human amyloid fibril proteins have been identified, and amyloid aggregation is associated with pathological manifestations such as Alzheimer’s disease, spongiform encephalopathy and type 2 diabetes.

  3. 2. Links between plasma apoE and glucose metabolism, brain insulin signaling, and synaptic integrity : Relevance to Alzheimer’s disease pathophysiology

    Författare :Anna Edlund; Henrietta Nielsen; William Rebeck; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer’s disease; apolipoprotein E; insulin; metabolism; Amyloid precursor protein APP ; Fe65; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Sammanfattning : Human apolipoprotein E (apoE) exists as three main isoforms called apoE2, apoE3, and apoE4, of which the E4 isoform is associated with increased Alzheimer’s disease (AD) risk. Brain glucose hypometabolism, linked to synaptic dysfunction, occurs years before symptom onset in AD, especially in APOEε4-carriers. LÄS MER

  4. 3. Evaluation of amyloid precursor protein and ß-amyloid as biomarkers for Alzheimer s disease

    Författare :Annika Olsson; Göteborgs universitet; []
    Nyckelord :Alzheimer s disease; amyloid precursor protein; ß-amyloid; biomarker; cerebrospinal fluid; enzyme-linked immunosorbent assay; plasma;

    Sammanfattning : Alzheimer s disease (AD) is a neurodegenerative disorder characterised by accumulations of neurofibrillary tangles and amyloid plaques. The major components of the amyloid deposits are the ß-amyloid (Aß) peptides derived from the amyloid precursor protein (APP). LÄS MER

  5. 4. Development of MALDI Mass Spectrometry Imaging Methods for Probing Spatial Lipid Biochemistry of Amyloid Plaques in Alzheimer's Disease

    Författare :Ibrahim Kaya; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer s disease; Lipids; Amyloid plaques; Mass spectrometry imaging; MALDI; Trimodal MALDI; Static MALDI; Dual polarity MALDI-MSI on the same pixel points; Neurodegeneration; Immunopathology; Amyloid peptides; APOE; Myelin; Sulfatides; 5xFAD; tgSwe; tgArcSwe; APP;

    Sammanfattning : Alzheimer’s disease (AD) is the most prevalent cause of neurodegenerative dementia. Aggregation of amyloid β (Aβ) peptides into extracellular Aβ plaques is one of the major neuropathological features of AD. LÄS MER

  7. 5. Statin treatment and beta-Amyloid Production in Patients with Alzheimer s Disease

    Författare :Kina Höglund; Göteborgs universitet; []
    Nyckelord :Alzheimer s disease; amyloid precursor protein; beta-amyloid; cholesterol; statins; CSF;

    Sammanfattning : Alzheimer s disease (AD) is a progressive neurodegenerative disorder pathologically characterized by neurofibrillary tangles and amyloid plaques. According to the amyloid cascade hypothesis, the increased production of beta-amyloid (Abeta), derived form the amyloid precursor protein (APP), and its aggregation into plaques are key pathological events, driving neurodegeneration in AD.
