  2. 6. Serological and molecular methods for surveillance of influenza A virus

    Author : Sofie Wallerström; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : 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.

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

    Author : Stefan Gaunitz; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : 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. 8. Influenza A virus in wild birds

    Author : Anders Wallensten; Björn Olsen; Lennart Svensson; Åke Lundkvist; Mikael Berg; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Influenza A virus; Wild Birds; Ducks; Prevalence; Ecology; Virology; Virologi;

    Abstract : Influenza virus is a RNA virus that exists as different types and subtypes. Influenza A virus strains are known to cause disease in several bird and mammalian species. Wild birds are believed to constitute the natural reservoir for influenza A virus. READ MORE

  6. 9. Influenza Neuraminidase : Novel mechanisms of influenza NA that enable adaptation and promote diversification

    Author : Hao Wang; Robert Daniels; Colin Russell; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Influenza; IAV; neuraminidase; transmembrane domain; the central Ca2 binding site; heterotetrameric formation; viral incorporation; evolution; adaptation; diversification; Biochemistry; biokemi;

    Abstract : Influenza A viruses (IAVs) are one of the most common human respiratory pathogens and are largely responsible for the seasonal influenza epidemics that cause mild to severe disease. The two IAV glycoproteins, hemagglutinin (HA or H) and neuraminidase (NA or N), serve as the major surface antigens and also are the main determinants of infectivity, pathogenicity and transmissibility.

  7. 10. The large sialoglycoprotein of human lymphocytes

    Author : Bernt Axelsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : L-LSGP is an abundant cell surface glycoprotein (a.m.w. intact 115—125 kdalton, desialylated 140—160 kdalton) restricted to lymphocytes in the hemopoietic system. READ MORE
