  1. 11. Misfolded superoxide dismutase-1 in sporadic and familial Amyotrophic Lateral Sclerosis

    Författare :Karin Forsberg; Thomas Brännström; Irina Alafuzoff; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ALS; SOD-1 motor neuron; protein misfolding; intranuclear; antibodies; CNS; brain; patologi; Pathology;

    Sammanfattning : Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative syndrome of unknown etiology that most commonly affects people in middle and high age. The hallmark of ALS is a progressive and simultaneous loss of upper and lower motor neurons in the central nervous system that leads to a progressive muscle atrophy, paralysis and death usually by respiratory failure.

  2. 12. α-Synuclein Fibril Formation and the Effects of Lipid Membranes

    Författare :Ricardo Gaspar; Fysikalisk kemi; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 13. Secondary Nucleation in Amyloid Formation

    Författare :Mattias Törnquist; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alzheimer s disease; amyloid; Ab42; aggregation mechanism; aggregation kinetics; secondary nucleation; Protein misfolding;

    Sammanfattning : Research into Alzheimer's disease is still hampered by a lack of fundamental understanding of the underlying mechanisms. While the aggregation of the amyloid β peptide (Aβ) into amyloid fibrils is highly implicated as a key factor in the disease, the molecular nature of its involvement has proven complex and elusive.

  5. 15. Susceptibility genes in conformational diseases

    Författare :Malin von Otter; Göteborgs universitet; []
    Nyckelord :Conformational disease; Alzheimer’s disease; Parkinson’s disease; Cataract Protein aggregation; Cellular transport; Oxidative stress; Susceptibility; genes; SNP; Haplotype;

    Sammanfattning : Conformational diseases are characterized by protein misfolding and aggregation in the affected tissue. The aim of this thesis was to find genetic support for mechanisms in common for three prevalent ... LÄS MER
