  1. 16. Oxidative mechanisms in London Familial Alzheimer´s disease and LPS-induced inflammation

    Författare :Katarina Reis; Tiit Land; Maria de Sousa; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurochemistry; Neurokemi; Neurochemistry and Molecular Neurobiology; neurokemi med molekylär neurobiologi;

    Sammanfattning : Alzheimer´s disease (AD) is the most common of the progressive neurodegenerative disorders and is characterized by the formation of Aβ deposits, neurofibrillary tangles and loss of neurons. Additional features of the disease are inflammation, increased oxidative stress and modified iron metabolism. LÄS MER

  3. 17. Structures, toxicity and internalization of cell-penetrating peptides

    Författare :Emelía Eiríksdóttir; Ülo Langel; Michael Gait; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CPP; cell-penetrating peptide; internalization; toxicity; structures; Neurochemistry; Neurokemi; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Sammanfattning : Cellular internalization is a highly regulated process controlled by proteins in the plasma membrane. Large and hydrophilic compounds, in particular, face difficulties conquering the plasma membrane barrier in order to gain access to intracellular environment. This puts serious constrains on the drug industry since many drugs are hydrophilic. LÄS MER

  4. 18. Chimeric gene delivery vectors : Design, synthesis, and mechanisms from transcriptomics analysis

    Författare :Moataz Dowaidar; Ülo Langel; Sandrine Sagan; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell-penetrating peptides; magnetic nanoparticles; graphene oxide; autophagy; siRNA; SCO; QSAR; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Sammanfattning : Delivery of nucleic acid is a promising approach for genetic diseases/disorders. However, gene therapy using oligonucleotides (ONs) suffers from low transfection efficacy due to negative charges, weak cellular permeability, and enzymatic degradation. LÄS MER

  5. 19. RNA binding proteins and epigenetics in SCA7

    Författare :Frida Niss; Anna-Lena Ström; Ann-Kristin Östlund-Farrants; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Sammanfattning : Polyglutamine diseases are a group of nine disorders that includes, among others SCA7. The common denominator is an expanded glutamine tract in the respective disease protein caused by unstable replication during meiosis. LÄS MER

  7. 20. The adaptor protein Fe65 and APP processing

    Författare :Niina Koistinen; Kerstin Iverfeldt; Susanne Frykman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Sammanfattning : The amyloid precursor protein (APP) protein has been in the limelight of research on Alzheimer´s disease (AD) pathogenesis because its proteolytic processing gives rise to the neurotoxic amyloid β (Aβ) peptide, the main constituent of amyloid plaques in the brains of AD patients. APP is sequentially processed by at least three different proteases termed α-, β-, and γ-secretases. LÄS MER
