    Sammanfattning : Alzheimer’s disease is an incurable neurodegenerative disorder linked to the amyloid β (Aβ) peptide, a 38-43 residue peptide. The detailed molecular disease mechanism(s) is (are) unknown, but oligomeric Aβ structures are proposed to be involved. LÄS MER

  2. 2. On the molecular mechanisms of the amyloid β-peptide aggregation

    Författare :Kalyani Sanagavarapu; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein aggregation; amyloid β-peptide; aggregation kinetics; aggregation mechanism N-terminus; mutations; variants; sequence determinants; ; cross-seeding;

    Sammanfattning : The pathogenesis of Alzheimer’s disease is widely believed to be due to production and deposition of the amyloid β-peptide. Several variants of the Aβ peptide are known to exist in in vivo. Variations include mutations or additional functional groups attached to residue side chains and may affect the aggregation process.

  3. 3. Understanding secondary nucleation of the amyloid β peptide

    Författare :Dev Thacker; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alzheimer s disease AD ; A beta 1-42; Amyloid aggregation; secondary nucleation;

    Sammanfattning : Alzheimer’s Disease (AD) is a devastating neurodegenerative disease associated with massive neuronal cell death during its pathology. The involvement of the amyloid β 42 (Aβ42) peptideand its role in neurotoxicity is now well established. LÄS MER

  5. 5. Amyloid β peptide: from monomer solubility to fibril structure

    Författare :Veronica Lattanzi; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alzheimer´s disease; Aβ solubility; small angle scattering; number of filaments; Aβ40; Aβ42 and Aβ42 S26Q ; fibril structure;

    Sammanfattning : Alzheimer´s disease (AD) is the most common human neuro-degenerative disease characterized by the formation of cerebral plaques. Several are the amyloid-beta (Aβ) variants found in the brain of healthy individuals. LÄS MER
