  1. 1. Avian antibodies applied in particle enhanced turbidimetric immunoassay : Developement of serum/plasma calprotectin immunoassay and its clinical performance as a marker for bacterial infections

    Författare :Tom Nilsen; Anders Larsson; Bjørn Steen Skålhegg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sepsis; avian antibodies; calprotectin antigen; particle enhanced turbidimetric immunoassay.; Clinical Chemistry; Klinisk kemi;

    Sammanfattning : Calprotectin is a cytosolic protein in the granulocytes, consisting of S100A8 and S100A9. On the site of inflammation, the neutrophils release the cytosol as an inflammatory response. The circulating calprotectin concentration increases and can therefore be used as marker for neutrophil activation and inflammation. LÄS MER

  3. 2. Avian IgY antibody : In vitro and in vivo

    Författare :David Carlander; Lennart Hammarström; Uppsala universitet; []
    Nyckelord :Medical sciences; Antigen production; chicken; cystic fibrosis; egg; ELISA; IgY; immunotherapy; Pseudomonas aeruginosa; yolk; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Chemistry; klinisk kemi;

    Sammanfattning : Immunoglobulin Y (IgY) is the major antibody found in eggs from chicken (Gallus domesticus). IgY can be used as an alternative to mammalian antibodies normally used in research, and its use in immunotherapy has recently been proposed. LÄS MER

  4. 3. Studies on O-glycosylation of mucin-type proteins and their binding to antibodies, bacterial toxins and viral receptors

    Författare :Stefan Gaunitz; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Carbohydrates are ubiquitous on the surface of all cells in mammals where they are involved in interactions with the surroundings (extracellular matrix), other cells (including self and non-self) and microbes (bacteria and virus). Carbohydrate-protein interactions in nature are often mediated via multivalent binding where the combined strength of multiple receptor- ligand interactions results in a binding that is highly specific and strong.

  5. 4. Serological and molecular methods for surveillance of influenza A virus

    Författare :Sofie Wallerström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The natural reservoir for influenza A viruses is birds, and numerous outbreaks of highly pathogenic avian influenza viruses have been documented. There is a risk of novel subtypes originating from birds infecting humans, and the question of migratory birds as long-distance vectors for highly pathogenic avian influenza viruses has also been raised.

  7. 5. Costs and benefits of immune system activation on physiology, behavior and offspring phenotype from an immunoecological perspective

    Författare :Sandra Sköld Chiriac; Evolutionär ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; immunoecology; acute-phase response; sickness behaviors; energy expenditure; fever; hypothermia; life history; maternal effects; terminal investment; costs of immune responses; Taeniopygia guttata; Parus major; Cyanistes caeruleus;

    Sammanfattning : Pathogen challenges and host immune defenses can have substantial impact on life history patterns of animals. Biotic and abiotic factors may affect immunity in wild animals, influencing e.g., population dynamics and sexual selection. LÄS MER
