  1. 1. Autoantibodies and the Type I Interferon System in the Etiopathogenesis of Systemic Lupus Erythematosus

    Författare :Stina Blomberg; Johan Frostegård; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Systemic lupus erythematosus; type I interferon; interferon inducer; dendritic cell; natural interferon-alpha producing cell; immune complex; SSA Ro; dsDNA; BDCA; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; Medicine; medicin;

    Sammanfattning : In sera remitted for anti-nuclear antibody (ANA) analysis, the supplement of a sensitive anti-SSA/Ro ELISA to the conventional ANA screening by immunofluorescence (IF) revealed that one fourth of the individuals with IF-ANA negative, but SSA/Ro ELISA positive sera, had systemic lupus erythematosus (SLE) or cutaneous LE. Consequently, adding a sensitive anti-SSA/Ro ELISA to the ANA screening is valuable for the serological detection of ANA negative SLE/LE patients. LÄS MER

  2. 2. RNA in model lipid membranes - interactions in bulk and at surfaces

    Författare :Agnes Michanek; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ssRNA; RNA origami; dsDNA; selfassembly phospholipids; model membranes; monolayer; QCM-D; DSC; Neutron reflectometry; hydrophobic interaction; cationic surfactants; sphingosine; phase behavior;

    Sammanfattning : The work presented in the thesis “RNA in model lipid membranes- interactions in bulk and at surfaces” aims to characterize the interaction between RNA and model membranes with different properties as well as to determine if ssRNA associate with model membranes in different ways. Several techniques have been used to characterize these systems, including quartz crystal microbalance with dissipation monitoring (QCM-D), Langmuir film balance in combination with neutron reflectometry and fluorescence microscopy as well as differential scanning calorimetry (DSC) and isothermal titration calorimetry (ITC).

  3. 3. Structural Studies of Large dsDNA Viruses using Single Particle Methods

    Författare :Hemanth Kumar Narayana Reddy; Martin Svenda; Sarah Butcher; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PR772; phage; PRD1; Bacteriophage; coliphage; Melbournevirus; Cedratvirus; lurbo; Pithovirus; CryoEM; Single particle imaging; Coherent; Diffractive; Imaging; Soft X-ray; Microscopy; Microscope; GDVN; High resolution; XFEL; aerosol; Injection; electrospray; gas dynamic virtual nozzle; CDI; CXI; FEL; Chemistry with specialization in Biophysics; Kemi med inriktning mot biofysik;

    Sammanfattning : Structural studies of large biological assemblies pose a unique problem due to their size, complexity and heterogeneity. Conventional methods like x-ray crystallography, NMR, etc. are limited in their ability to address these issues. To overcome some of these limitations, single particle methods were used. LÄS MER

  4. 4. Homing Endonucleases and Horizontal Gene Transfer in Bacteria and Bacteriophages

    Författare :David Nord; Britt-Marie Sjöberg; Steinar Johansen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dsDNA cleavage; ribonucleotide reductase; GIY-YIG motif; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Homing endonuclease genes (HEGs) are selfish genetic elements that mediate their own super-Mendelian inheritance. This is mediated by the homing endonuclease cleavage of a HEG- allele followed by recombination-repair with a HEG+ allele.The majority of the HEGs are encoded in intervening sequences (IVSs).

  5. 5. Studies on anti-dsDNA Antibodies and other potential biomarkers in Systemic Lupus Erythematosus

    Författare :Michele Compagno; Reumatologi och molekylär skelettbiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Systemic Lupus Erythematosus Anti-dsDNA antibodies Biomarkers Osteopontin S100A8 A9 LE-cells Diagnostic accuracy Longitudinal study Multicentre study;

    Sammanfattning : Systemic Lupus Erythematosus (SLE) is characterized by chronic inflammation involving many organ systems. The etiology is unknown and the pathogenesis has not been fully elucidated. Impairments of the immune system and of the mechanisms regulating cell death are commonly seen in SLE patients. LÄS MER
