  1. 1. Stereotyped B Cell Receptors in Chronic Lymphocytic Leukaemia Implications for Antigen Selection in Leukemogenesis

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Fiona Murray; Richard Rosenquist Brandell; Kostas Stamatopoulos; Gunilla Enblad; Gerard Tobin; Manlio Ferrarini; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chronic lymphocytic leukaemia; immunoglobulin genes; somatic hypermutation; stereotyped B cell receptors; antigen selection; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Clinical genetics Molecular biology; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Klinisk genetik Molekylärbiologi;

    Abstract : Biased immunoglobulin heavy variable (IGHV) gene usage and distinctive B-cell receptor (BCR) features have been reported in chronic lymphocytic leukaemia (CLL), which may reflect clonal selection by antigens during disease development. Furthermore, the IGHV gene mutation status distinguishes two clinical entities of CLL, where patients with unmutated IGHV genes have an inferior prognosis compared to those with mutated IGHV genes.

  2. 2. Array-based Characterization of Chronic Lymphocytic Leukemia - with Focus on Subsets Carrying Stereotyped B-cell Receptors

    University dissertation from Uppsala : Acta Universitatis Upsaliensis Uppsala

    Author : Millaray Marincevic; Richard Rosenquist; Andreas Rosenwald; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chronic lymphocytic leukemia; array-based characterization; stereotyped B-cell receptors; subsets; antigens; SNP array; gene expression array; methylation array; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Clinical genetics; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Klinisk genetik; Clinical Genetics; Klinisk genetik;

    Abstract : In chronic lymphocytic leukemia (CLL), the presence of multiple subsets expressing ‘stereotyped’ B-cell receptors (BCRs) has implicated antigen(s) in leukemogenesis. These stereotyped subsets display similar immunoglobulin (IG) gene usage, almost identical complementarity determining region 3’s and may share clinical features. READ MORE

    Abstract : Mantle cell lymphoma (MCL) and chronic lymphocytic leukemia (CLL) both belong to the group of mature B-cell malignancies. However, MCL is typically clinically aggressive while the clinical course of CLL varies. READ MORE

  4. 4. B cell subsets in autoimmune disease

    University dissertation from Stockholm : Karolinska Institutet, Dept of Medicine, Solna

    Author : Katrin Habir; Karolinska Institutet.; Karolinska Institutet.; [2018]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    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

  5. 5. Genomic and Molecular Aspects of Mature Human B Cells

    University dissertation from Carl-Magnus Högerkorp Department of Immunotechnology Lund University

    Author : Carl-Magnus Högerkorp; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transplantation; Human; B-cell; Germinal center; Centroblast; serology; Immunology; onkologi; cancer; Cytologi; cancerology; oncology; Microarray; Cytology; Mantel cell lymphoma; Immunologi; serologi; Centrocyte;

    Abstract : This thesis covers aspects of the mature human B cell and its different guises on its way to become a fully differentiated antibody forming plasma cell (AFC), the key player in the humoral immune system. The understanding of the complex molecular mechanisms taking place in the B cell, as it first encounters antigen, enters the germinal center (GC) reaction, giving rise to memory cells and plasma cells, is not only of importance for the curious scientist, but will also benefit the understanding of B cells in disease.
