  1. 6. Self-assembly of amyloid-β peptides in the presence of metal ions and interacting molecules – a detour of amyloid building blocks

    Författare :Cecilia Mörman; Astrid Gräslund; Daniel Otzen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biophysics; Alzheimer’s disease; protein aggregation; amyloid formation; amyloid-β peptide; aggregation kinetics; interactions; metal ions; designed peptide constructs; Tau protein; NMR; circular dichroism; fluorescence spectroscopy; Biophysics; biofysik;

    Sammanfattning : Misfolding of proteins into amyloid structures is implicated as a pathological feature in several neurodegenerative diseases and the molecular causes are still unclear. One typical characteristic of Alzheimer’s disease is self-assembly and accumulation of soluble amyloid-β (Aβ) peptides into insoluble fibrils and plaques. LÄS MER

  3. 7. Processing of the amyloid precursor protein and its paralogues amyloid precursor-like proteins 1 and 2

    Författare :Linda Adlerz; Kerstin Iverfeldt; Richard Cowburn; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; APP; APLP1; APLP2; Alzheimer s disease; Amyloid β-peptide; Processing; RA; BDNF; IGF-1; curcumin; PI3-K; MAPK; cdk5; Neurochemistry; Neurokemi; Neurochemistry and Molecular Neurobiology; neurokemi med molekylär neurobiologi;

    Sammanfattning : Alzheimer’s disease (AD) is a neurodegenerative disorder which is histopathologically characterised by amyloid plaques and neurofibrillary tangles. Amyloid plaques consist of the amyloid β-peptide (Aβ) that can form aggregates in the brain. Aβ is generated from the amyloid precursor protein (APP) through proteolytic cleavage. LÄS MER

  4. 8. Secondary Nucleation in Amyloid Formation

    Författare :Mattias Törnquist; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alzheimer s disease; amyloid; Ab42; aggregation mechanism; aggregation kinetics; secondary nucleation; Protein misfolding;

    Sammanfattning : Research into Alzheimer's disease is still hampered by a lack of fundamental understanding of the underlying mechanisms. While the aggregation of the amyloid β peptide (Aβ) into amyloid fibrils is highly implicated as a key factor in the disease, the molecular nature of its involvement has proven complex and elusive.

  5. 9. Pathogenesis of Alzheimer's disease : focus on amyloid β-peptide, homocysteine and metals

    Författare :Dorota Religa; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Alzheimer's disease (AD) is a complex dementia disorder. It is characterized by the neuronal and synaptic loss, presence of neurofibrillary tangles and senile plaques, composed of amyloid β-peptide (Aβ) in the brain. LÄS MER

  7. 10. Alzheimer disease : a super-resolved picture of the amyloid β-peptide producing machinery

    Författare :Yang Yu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Alzheimer disease (AD) is the most common neurodegenerative disease, influencing 40 million patients in the world. Pathologically, AD is hallmarked by intracellular tau tangles and extracellular Amyloid-β peptide (Aβ) plaques. Aβ is generated from the amyloid precursor protein (APP) and its C-terminal fragment (APP-CTF). LÄS MER
