1. 16. Co-assembly of proteins and lipids : From lipodiscs to amyloid aggregates

   Författare :Rebecca Frankel Willén; NanoLund: Centre for Nanoscience; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; amyloid; Aβ42; apolipoprotein A-1; aggregation; high-density lipoprotein; DNAJB6; Alzheimer s disease; protein-lipid interactions;

   Sammanfattning : Assemblies of different molecules is a prevalent phenomenon in nature, and crucial in biological life. Most of the biological assemblies are co-assembledcomposites, made up from several different components, either of thesame biomolecular type or a combination of different ones. LÄS MER

3. 17. Fluorescent Probes and Protein Misfolding: Methods and Applications

   Författare :Irem Nasir; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protein misfolding; fluorophores; filter-trap; site-specific fluorophore labeling; amyloid-beta; microscopic rate constants; solvatochromic probes; alpha-synuclein; lipid vesicles; nanoparticles; protein adsorption;

   Sammanfattning : Protein misfolding is a frequently occurring event in living cells and without the quality control, the consequences are disasterous. In this thesis, we studied protein misfolding in vitro by employing a variety of fluorophores, to either detect the highly ordered aggregates of intrinsically disordered proteins/peptides or slight misfolding of a natively folded protein.

4. 18. Hierarchical Assembly Investigations and Multiscale Characterization of Protein-based Materials : Insights from Whey Protein Nanofibrils and Recombinant Spider Silk Microspheres

   Författare :Eirini Ornithopoulou; My Hedhammar; Thomas Crouzier; Christina Divne; Tim Melander Bowden; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hierarchical Assembly; Protein-based materials; Whey Protein Nanofibrils; β-Lactoglobulin; Recombinant Spider Silk; Microspheres; Biomedical Applications; Surface Biofunctionalization; Hierarkisk montering; Proteinbaserade material; Vassleprotein nanofibriller; β-Laktoglobulin; Rekombinant spindelsilke Mikrosfärer; Biomedicinska tillämpningar; Ytbiokonjugering; Biotechnology; Bioteknologi;

   Sammanfattning : Protein-based materials, with their unique properties of combining high strength, while maintaining elasticity, and their inherent biocompatibility, hold immense potential for various applications. In order to harness these properties, we need to understand and control how protein building blocks come together to form hierarchically structured materials. LÄS MER

5. 19. Role of pro-inflammatory S100A9 protein in amyloid-neuroinflammatory cascade in Alzheimer’s disease and traumatic brain injury

   Författare :Chao Wang; Ludmilla Morozova-Roche; Jonathan Gilthorpe; Øyvind Halskau; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; S100A9; Aβ; Alzheimer s disease; Traumatic brain injury; Amyloid; Neuroinflammatory; medicinsk biokemi; Medical Biochemistry;

   Sammanfattning : Background Traumatic brain injury (TBI) is a complex disease with a spectrum of symptoms and disabilities. Over the past decade TBI has become the focus of research due to growing epidemiological and clinical evidences that TBI incidences are strong risk factors for Alzheimer’s disease (AD). LÄS MER

7. 20. The Molecular Chaperone DNAJB6 - A Suppressor of Disease Related Amyloid Fibril Formation

   Författare :Cecilia Månsson; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DNAJ; HSP40; molecular chaperones; amyloid fibrils; Alzheimer’s disease; Huntington’s Disease; crosslinking mass spectrometry; chemical kinetics; aggregation; fibril formation;

   Sammanfattning : Several neurodegenerative diseases are caused by peptides or proteins forming amyloid fibrils such as the Aβ peptide involved in Alzheimer’s disease and the huntingtin exon-1 with a prolonged polyglutamine (polyQ) stretch involved in Huntington’s disease. The ability to form amyloid fibrils is an intrinsic feature in all proteins. LÄS MER
