  1. 6. Cellular responses to amyloid-beta protofibrils : Focus on astrocytes, extracellular vesicles and antibody treatment

    Författare :Elisabeth Nikitidou; Anna Erlandsson; Martin Ingelsson; Gunnar K. Gouras; Uppsala universitet; []
    Nyckelord :Alzheimer’s disease; Amyloid-beta; Protofibrils; Astrocytes; Extracellular vesicles; Antibody; Neurons; Degradation; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Knowledge about the cellular mechanisms behind the initiation and propagation of Alzheimer’s disease (AD) is limited. Decades of research have focused on neuronal abnormalities in AD, but recently more attention has been given to the glial cells. LÄS MER

  3. 7. Islet amyloid polypeptide (IAPP) in Type 2 diabetes and Alzheimer disease

    Författare :Marie Oskarsson; Gunilla Westermark; Mikael Oliveberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amyloid; IAPP; Abeta; type 2 diabetes; Alzheimer disease; BRICHOS; heparan sulfate; islet amyloid; amyloid plaques; seeding; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : The misfolding and aggregation of the beta cell hormone islet amyloid polypeptide (IAPP) into amyloid fibrils is the main pathological finding in islets of Langerhans in type 2 diabetes. Pathological assemblies of IAPP are cytotoxic and believed to contribute to the loss of insulin-producing beta cells. LÄS MER

  4. 8. Amyloid Beta – Biotherapy Target and Biotechnological Tool

    Författare :Sebastian W. Meister; Stefan Ståhl; John Löfblom; Maarten Merkx; KTH; []

    Sammanfattning : Alzheimer’s disease is a progressive neurodegenerative disease characterized primarily by memory impairment and cognitive decline. As of 2020, an estimated 50 million people suffer from Alzheimer’s disease or related dementia and no disease-modifying treatment options are yet approved for clinical practice. LÄS MER

  5. 9. Islet Amyloid Polypeptide: Interaction with Amyloid Beta, Alpha-Synuclein and BRICHOS

    Författare :Ye Wang; Gunilla Westermark; Ludmilla Morozova-Roche; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amyloid; IAPP; Abeta; alpha-synuclein; Bri2 BRICHOS; luminescent conjugated oligothiophenes; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning :  Amyloid, the congophilic deposits of misfolded protein, are pathological hallmarks of many common diseases, among others, Alzheimer’s disease (AD), Parkinson’s disease (PD), and type 2 diabetes (T2D). Amyloid beta (Aβ) forms senile plaques in AD, alpha-synuclein (aSyn) forms Lewy bodies and Lewy neurites in PD, islet amyloid polypeptide (IAPP) forms islet amyloid in T2D. LÄS MER

  7. 10. Kinetic stabilization of transthyretin and its role as an inhibitor of Aβ amyloid formation

    Författare :Lina Nilsson; Anders Olofsson; Elisabeth Sauer-Eriksson; Gunilla Westermark; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Amyloid; transthyretin; amyloid beta; kinetic stabilizer; biokemi; Biochemistry;

    Sammanfattning : Amyloid formation occurs when normally soluble proteins and peptides misfold and aggregate into intractable threadlike structures called fibrils. There are currently more than 30 proteins associated with this aberrant structure, including the Aβ peptide in Alzheimer’s disease (AD) and transthyretin (TTR) in TTR amyloidosis. LÄS MER
