  1. 1. On Minor Salivary Gland Secretion

    Author : Lars Eliasson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; age; dental plaque pH; dentures; gender; health; IgA; medication; minor salivary glands; oral dryness; saliva; salivary secretion rate;

    Abstract : The overall aim of this series of studies has been to examine palatal, buccal and labial minor salivary gland secretions in relation to age and gender and other factors and conditions that could have effects on the saliva. Further aims were to analyze minor salivary gland secretions in relation to feelings of oral dryness and dental plaque pH. READ MORE

  2. 2. Intestinal IgA synthesis: Localization and requirements for IgA class switch recombination

    Author : Peter Bergqvist; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; IgA; Intestine; Gut associated lymphoid tissue; class switch recombination; CD40; germ free;

    Abstract : Production of IgA at mucosal surfaces is one of the most striking features of the mucosal immune system. Despite that IgA was first discovered in the 1950’s and secretory IgA described in gut secretions and breast milk in the mid 1960’s we still have limited information about the sites and exact requirements for IgA class switch recombination.

  3. 3. Studies on streptococcal M proteins. Interactions with IgA and human complement regulators

    Author : Eskil Johnsson; Institutionen för laboratoriemedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; antigenic variation; factor H; C4b-binding protein; Fc-receptor; IgA; Streptococcus pyogenes; M protein; mykologi; virologi; bakteriologi; Mikrobiologi; virology; mycology; bacteriology;

    Abstract : The human pathogenic bacterium Streptococcus pyogenes (group A Streptococcus) expresses several different virulence factors. Of these, the M protein is regarded as one of the most important, because it confers resistance to phagocytosis, allowing the bacterium to multiply in blood. READ MORE

  4. 4. Mucosal immunity in the respiratory tract : The role of IgA in protection against intracellular pathogens

    Author : Ariane Rodríguez; Carmen Fernández; Lennart Hammarström; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mucosal immunity; respiratory tract; IgA; intracellular pathogens; Immunology; Immunologi;

    Abstract : The lungs and upper airways are mucosal surfaces that are common site for infection with an enormous variety of inhaled pathogens. Therefore, induction of immune responses in the respiratory tract is crucial for protection against respiratory diseases. One of the pathogens infecting the host via the respiratory tract is Mycobacterium Tuberculosis. READ MORE

  5. 5. Studies on Potency and breadth of HIV-1, HIV-2 and SIV neutralizing antibody responses

    Author : Gülsen Özkaya Sahin; Avdelningen för medicinsk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HIV-1; HIV-2; SIV; envelope; neutralizing antibody; breadth; potency; IgG; IgA; complement; antibody-dependent complement-mediated inactivation; virus evolution; diversity; divergence;

    Abstract : Even though the relative contribution of neutralizing antibodies (Nab) to prevent progression to AIDS during HIV-1 infection is still unclear, the induction of broadly NAb directed against HIV-1 through vaccination is considered to represent an important goal for the development of HIV-1 vaccines. Factors contributing to the induction of NAb may include the strength and duration of antigenic stimulation, the preservation of CD4+ T and B cells, the conformation of the HIV-1 envelope glycoprotein complex (Env), and the evolution of Env during infection.
