  1. 26. Exploring Monoclonal Antibody Action Against the Group A Streptococcal M Protein

    Författare :Sebastian Wrighton; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; group A streptococcus; Streptococcus pyogenes; fibronectin; phagocytosis; innate immunity; antibodies; adaptive immunity;

    Sammanfattning : Group A Streptococcus (GAS) is a significant human pathogen that has developed multipleimmune evasion mechanisms to counter the host immune response. One of these mechanisms involvesthe production of the M protein, which, amongst other things, acts as an anti-phagocytic factor and canbind host proteins. LÄS MER

  3. 27. Therapeutic potential of extracellular vesicles

    Författare :Oscar Wiklander; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Extracellular vesicles (EVs) are nanometer-sized, lipid membrane enclosed, vesicles that are secreted by most, if not all, cells and contain macromolecular material of the source cell including lipids, proteins and various nucleic acid species. Over the last two decades, EVs have been recognized as important mediators of cell-to-cell communication that influence both physiological and pathological conditions. LÄS MER

  4. 28. Effects of invasin and YopH of Yersinia pseudotuberculosis on host cell signaling

    Författare :Anna Gustavsson; Maria Fällman; Arnoud Sonnenberg; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; β1-integrin; Yersinia pseudotuberculosis; Invasin; YopH; Cell-Matrix Adhesion; Filopodia; Cell Spreading; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Integrins are a large family of membrane-spanning heterodimeric (αβ) receptors that bind to ligands on other cells or to extracellular matrix (ECM) proteins. These receptors mediate bidirectional signaling over the cell membrane to induce signaling cascades mediating functions as cell adhesion, spreading and migration. LÄS MER

  5. 29. Immunotoxicology in Marine Invertebrates - Effects of Manganese on Immune Response

    Författare :Carolina A. M. Oweson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Invertebrates; Immune system; Haemocytes; Manganese Mn ; Immunotoxicology; Crustacea; Mollusca; Echinodermata;

    Sammanfattning : Manganese, Mn, is an abundant element in nature, particularly in soft bottom sediments of the oceans and in bedrock. The metal is predominantly bound to the sediment in the colloid state, MnO2. LÄS MER
