  1. 1. Capturing transient peptide assemblies associated with Alzheimer's disease : Native mass spectrometry studies of amyloid-β oligomerization

    Author : Nicklas Österlund; Astrid Gräslund; Leopold L. Ilag; Mikael Oliveberg; Sheena E. Radford; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Protein aggregation; amyloid-β; neurodegeneration; Alzheimer’s disease; chaperones; DnaJ; biomembranes; native mass spectrometry; Biophysics; biofysik;

    Abstract : Correct folding of proteins is essential for maintaining a functional living cell. Misfolding and aggregation of proteins, where non-native intermolecular interactions form large and highly ordered amyloid aggregates with low free energy, is hence associated with multiple diseases.

  2. 2. Spectroscopic studies of dynorphin neuropeptides and the amyloid beta-peptide : The consequences of biomembrane interactions

    Author : Loïc Hugonin; Astrid Gräslund; Bernard Lebleu; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biophysics; Biofysik; Biophysics; biofysik;

    Abstract : Dynorphin A, dynorphin B and big dynorphin are endogenous opioid neuropeptides. They play an important role in a wide variety of physiological functions such as regulation of pain processing and memory acquisition. Such actions are generally mediated through the κ-receptors.

  3. 3. Imaging of lipids and proteins in Alzheimer's disease using Time-of-Flight Secondary Ion Mass Spectrometry

    Author : Louise M Carlred; Chalmers tekniska högskola; []

    Abstract : Alzheimer’s disease (AD) is a neurodegenerative disease characterized by the formation of senile plaques. These plaques, which consist of aggregations of a peptide called amyloid-β, are deposited in-between the nerve cells in the brain, where they disrupt the signaling processes. READ MORE

  4. 4. Amyloid-β and lysozyme proteotoxicity in Drosophila : Beneficial effects of lysozyme and serum amyloid P component in models of Alzheimer’s disease and lysozyme amyloidosis

    Author : Liza Bergkvist; Ann-Christin Brorsson; Katarina Kågedal; Jan Johansson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : In the work presented this thesis, two different conditions that are classified as protein misfolding diseases: Alzheimer's disease and lysozyme amyloidosis and proteins that could have a beneficial effect in these diseases, have been studied using Drosophila melanogaster, commonly known as the fruit fly. The fruit fly has been used for over 100 years to study and better understand fundamental biological processes. READ MORE

  5. 5. Amyloid Proteins in Neurodegenerative Disease – Role of Extrinsic Modifiers

    Author : Nima Sasanian; Chalmers tekniska högskola; []

    Abstract : ABSTRACT Self-assembly of disease-associated proteins into fibrillar homopolymers, so-called “amyloid fibrils” is a pathological hallmark of several debilitating human disorders, including Alzheimer’s disease (AD) and Parkinson’s disease (PD). AD and PD are associated with the formation of amyloid fibrils from the proteins amyloid-β (Aβ) and α-syn (α-syn), in the extracellular and intracellular space, respectively. READ MORE
