  2. 16. Immunoecology of the Great Snipe (Gallinago media) : Mate Choice, MHC Variation, and Humoral Immunocompetence in a Lekking Bird

    Author : Robert Ekblom; Jacob Höglund; Mats Grahn; Scott V. Edwards; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Behaviour; Major histocompatibility complex class II B; Sexual selection; Evolution; Leks; Biologi; Biology; Biologi;

    Abstract : At the centre of the vertebrate immune system is a group of proteins called MHC (major histocompatibility complex) molecules. These function in self – non self recognition and activation of the immune defence against intruding parasites and pathogens. READ MORE

  4. 17. Bartonella Infections in Sweden: : Clinical Investigations and Molecular Epidemiology

    Author : Christian Ehrenborg; Martin Holmberg; Göran Friman; Eva Hjelm; Gunnar Sandström; Uppsala universitet; []
    Keywords : Communicable diseases; Bartonella; clinical studies; molecular epidemiology; Infektionssjukdomar;

    Abstract : Characteristically, in infections that are caused by the zoonotic pathogen Bartonella naturally infected reservoir hosts are asymptomatic, where infected incidental, non-natural, hosts develop symptomatic disease. Cat-scratch disease (CSD) is a well known example. READ MORE

  5. 18. Maturation of humoral immune responses : Studies on the effects of antigen type, apoptosis and age

    Author : Karin Lindroth; Carmen Fernández; Kenneth G.C. Smith; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; immunology; B cell; humoral immune response; Immunology; Immunologi;

    Abstract : The humoral immune response is dependent on the formation of antibodies. Antibodies are produced by terminally differentiated B cells, plasma cells. Plasma cells are generated either directly from antigen challenged B cells, memory cells or from cells that have undergone the germinal center (GC) reaction. READ MORE

  6. 19. B cell subsets in autoimmune disease

    Author : Katrin Habir; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : B lymphocytes are a type of white blood cells, belonging to the adaptive arm of the immune system and involved in creating immunological memory. B cells function in the humoral immune system by secreting antibodies which can bind pathogens to prevent them from doing further damage and to help other immune cells to target them. READ MORE

  7. 20. CD8+ T cell specificity in thymic selection and in the recognition of antigen

    Author : Johan Sandberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : T cell; specificity; MHC class 1; selection; tolerance;

    Abstract : Specificity mediated by the T cell receptor (TCR) is of fundamental importance for the ability of T cells to function, and regulate humoral immunity and effector mechanisms of the innate immune system. T cells recognize composite molecules consisting of products of the major histocompatibility complex (MHC) class I or class 11 loci, in complex with a short peptide fragment derived from endogenous or antigenic proteins.
