  1. 1. The Folding Energy Landscape of MerP

    Author : Ann-Christin Brorsson; Bengt-Harald Jonsson; Daniel Otzen; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; protein folding and stability; hydrogen exchange; intermediate; partial unfolding; Biokemi; Biochemistry; Biokemi; Biochemistry; biokemi;

    Abstract : This thesis is based on studies, described in four papers, in which the folding energy landscape of MerP was investigated by various techniques. MerP is a water-soluble 72 amino acid protein with a secondary structure consisting of four anti-parallel β-strands and two α-helices on one side of the sheet in the order β1α1β2β3α2β4. READ MORE

  2. 2. 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

  3. 3. Understanding the dual nature of lysozyme: part villain – part hero : A Drosophila melanogaster model of lysozyme amyloidosis

    Author : Linda Helmfors; Ann-Christin Brorsson; Bengt-Harald (Nalle) Jonsson; R. Luke Wiseman; Linköpings universitet; []
    Keywords : ;

    Abstract : Amyloid proteins are a distinct class of proteins that can misfold into β-sheet rich structures that later mature to form the characteristic species known as amyloid fibrils, and accumulate in tissues in the human body. The misfolding event is often caused by mutations (or outer factors such as changes in pH) that destabilize the native protein structure. READ MORE

  4. 4. The influence of lysozyme and oligothiophenes on amyloid-β toxicity in models of Alzheimer’s disease

    Author : Linnea Sandin; Katarina Kågedal; Ann-Christin Brorsson; Camilla Janefjord Warnqvist; Hanna Appelqvist; Susanne Frykman; Linköpings universitet; []

    Abstract : Alzheimer’s disease (AD) is a neurodegenerative disease and the most common cause of dementia worldwide. Apart from dominantly inherited mutations, age is the major risk factor and as life expectancy increases the prevalence for AD escalates dramatically. READ MORE
