2. 1. Amyloid Fibril Formation - Dye Detection and Effects of Lipids

   Author : David Lindberg; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; atomic force microscopy; fluorescence; Alzheimer’s disease; YOYO-1; amyloid fibrils; lipids; linear dichroism; FRET; circular dichroism; kinetics; Protein aggregation; insulin; thioflavin-T;

   Abstract : Amyloid fibrils are long fibrillar homopolymers of self-assembled proteins. They can be formed by essentially any polypeptide, but are of particular interest because of their occurrence in several incurable and debilitating human diseases, e.g. Alzheimer’s disease (AD). READ MORE

4. 2. NMR studies on interactions between the amyloid β peptide and selected molecules

   Author : Anna Wahlström; Astrid Gräslund; Göran Karlsson; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Amyloid β peptide; Alzheimer s disease; Aggregation; Oligomer; Amyloid; Interaction; Nuclear Magnetic Resonance Spectroscopy; Circular Dichroism Spectroscopy; Thioflavin T; Detergent; Congo red; Affibody; Cyclodextrin dimer; Metal ion; Chemistry; Kemi; Biochemistry; Biokemi; Biophysics; biofysik;

   Abstract : 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. READ MORE

5. 3. α-Synuclein Fibril Formation and the Effects of Lipid Membranes

   Author : Ricardo Gaspar; Fysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Protein misfolding; alpha-synuclein; Parkinson s disease; microscopic rate constants; Thioflavin T; ganglioside lipids; Exosomes; protein-lipid co-aggregation; model membranes; monomer-dependent secondary nucleation;

   Abstract : Amyloid protein aggregation results in major disturbances of cellular processes in humans. The most common amyloid-related disorders are Alzheimer´s disease and Parkinson´s disease. Parkinson´s disease is charaterized by the formation of protein-rich aggregates that are deposited in neurons, termed Lewy bodies and Lewy neurites. READ MORE

6. 4. Development of the Amyloid Fibril Characterisation Toolbox - New use for old dyes

   Author : David Lindberg; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Amyloid-β; Thioflavin-T; Fluorescence spectroscopy; YOYO-1; Amyloid fibrils; Linear dichroism; Alzheimer’s disease;

   Abstract : Amyloid fibrils are self-assembled protein homopolymers that playcentral roles in the pathology of several human diseases, most notably in progressiveneurodegenerative diseases such as Alzheimer’s disease (AD). In AD, fibrils areformed by the amyloid-β (Aβ) peptide, an enzymatic cleavage product that is naturallyproduced in human brain tissue. READ MORE

7. 5. Theoretical Studies of Protein-Ligand Interactions

   Author : Kuang Guanglin; Tu Yaoquan; Bulone Vincent; David van der Spoel; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Binding free energy; molecular dynamics; molecular docking; metadynamics; nicotinic receptor; amyloid fibril; PH domain; Theoretical Chemistry and Biology; Teoretisk kemi och biologi;

   Abstract : The protein-ligand interaction is an important issue in rational drug design and protein function research. This thesis focuses on the study of protein-ligand interactions using various molecular modeling methods, which are used in combination to predict the binding modes and calculate the binding free energies of several important protein-ligand systems, as summarized below.
