  2. 2. Activation, adhesion and motility of B lymphocytes in health and disease

    Author : Natalija Gerasimcik; Eva Severinson; Victor Tybulewicz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; B cells; activation; motility; IL-4; EBV; Dock10; Cdc42; Rac1 and Rac2; immunologi; Immunology;

    Abstract : B cells can be activated by T cell-dependent stimuli, such as CD40 ligation and cytokines, which induce extensive proliferation, class switch recombination and somatic hypermutation.Epstein-Barr virus (EBV) can also induce B cell activation by mimicking T cell help through its main oncoprotein, latent membrane protein 1 (LMP-1).

  3. 3. Regulatory properties of dendritic cells and B cells in adaptive immunity

    Author : Bengt Johansson Lindbom; Adaptivt immunförsvar; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; serology; transplantation; Immunologi; serologi; Immunology; Cellular differentiation; Cytokines; Dendritic cells; B lymphocytes; T lymphocytes;

    Abstract : This thesis is based upon four original papers in which human dendritic cells (DCs) and B cells have been analyzed in terms of how they influence the character of adaptive immune responses. DCs isolated from human tonsils were found to possess a capacity to directly regulate proliferation, isotype switching, and antibody production in B cells. READ MORE

  4. 4. Gene regulation by Early B-cell Factor (EBF)

    Author : Peter Åkerblad; Immunologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; serology; Immunology; B-lymphocytes; Differentiation; Transcription; EBF; Gene regulation; transplantation; Immunologi; serologi;

    Abstract : In this study we aimed at defining genes that are controlled by Early B-cell Factor (EBF), that could explain the severe block in B-cell development observed in EBF-/- mice. The fact that EBF appears to be important for the transcriptional control of genes encoding proteins in the pre-B and B-cell receptor complex implied to us that EBF could be a common regulator of other components in the pre-B and B-cell receptor.

  5. 5. Function and Regulation of B-cell Subsets in Experimental Autoimmune Arthritis

    Author : Anna-Karin E. Palm; Sandra Kleinau; Susanna Cardell; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; B cells; marginal zone; autoimmune arthritis; spleen; lymph node; antigen presentation; Fc gamma receptor IIb; complement receptors 1 and 2; mast cells; Biologi med inriktning mot molekylär immunologi; Biology with specialization in Molecular Immunology;

    Abstract : B lymphocytes play a significant role in autoimmune arthritis, with their function stretching beyond autoantibody production to cytokine secretion and presentation of autoantigen. However, the involvement and activation of different B-cell subset in the autoimmune response is not fully clear. READ MORE
