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

    Författare :Fiona Murray; Richard Rosenquist Brandell; Kostas Stamatopoulos; Gunilla Enblad; Gerard Tobin; Manlio Ferrarini; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chronic lymphocytic leukaemia; immunoglobulin genes; somatic hypermutation; stereotyped B cell receptors; antigen selection; Molecular biology; Molekylärbiologi;

    Sammanfattning : 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.

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

    Författare :Millaray Marincevic; Richard Rosenquist; Andreas Rosenwald; Uppsala universitet; []
    Nyckelord :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; Clinical genetics; Klinisk genetik; Clinical Genetics; Klinisk genetik;

    Sammanfattning : 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. LÄS MER

  4. 3. B cell subsets in autoimmune disease

    Författare :Katrin Habir; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

    Sammanfattning : 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. LÄS MER

  7. 5. Sex differences in immune response and sex hormone receptor expression in healthy individuals and during viral infection

    Sammanfattning : There is sex-bias in morbidity and mortality from infectious diseases. Infections kill more men than women and several studies have pointed out differences in the immune system as a reason. The sex hormones estrogen, progesterone and testosterone all shape the effect of the immune response on multiple levels. LÄS MER
