    Sammanfattning : Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative syndrome characterized by progressive degeneration of motor neurons that result in muscle wasting. The symptoms advance gradually to paralysis and eventually death. Most patients suffer from sporadic ALS (sALS) but 10% report a familial predisposition. LÄS MER

  3. 2. Protein Misfolding in Human Diseases

    Författare :Karin Almstedt; Per Hammarström; Daniel Otzen; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Misfolding; carbonic anhydrase; prion protein; protein stability; Biochemistry; Biokemi;

    Sammanfattning : There are several diseases well known that are due to aberrant protein folding. These types of diseases can be divided into three main categories:Loss-of-function diseasesGain-of-toxic-function diseasesInfectious misfolding diseases Most loss-of-function diseases are caused by aberrant folding of important proteins.

  4. 3. Prion-infection and Cellular Signaling : Influence of scrapie-infection on lipid raft-associated proteins

    Författare :Hanna Gyllberg; Katarina Bedecs; Albert Taraboulos; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : Prion diseases are a group of fatal neurodegenerative diseases affecting almost all mammals including humans. The diseases are caused by formation of the misfolded isoform of the cellular prion protein (PrPC) to the disease causing PrPSc. LÄS MER

  5. 4. Novel endogenous mechanisms of complement regulation - A delicate balance

    Författare :Andreas Holmér; Malmö Klinisk kemi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; short leucine rich glycoprotein; factor H; C1q; age-related macular degeneration; C4b-binding protein; prion disease; prion protein; Complement regulation; C-reactive protein;

    Sammanfattning : In this thesis, the biochemical mechanisms for complement activation by endogenous proteins are explored. The short leucine-rich repeat proteins (SLRPs) help organise extracellular matrices. We found that several SLRPs bind C1q and of these, fibromodulin and osteoadherin trigger complement. LÄS MER
