  1. 1. Analysis of Immunoglobulin Genes and Telomeres in B cell Lymphomas and Leukemias

    Författare :Sarah Walsh; Richard Rosenquist; Christer Sundström; Anna Laurell; Andreas Rosenwald; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; B cell lymphoma leukemia; mantle cell lymphoma; hairy cell leukemia; lymphoplasmacytic lymphoma; immunoglobulin genes; antigen selection; telomeres; cellular origin; somatic hypermutation; Genetik; Clinical genetics; Klinisk genetik;

    Sammanfattning : B cell lymphomas and leukemias are heterogeneous tumors with different cellular origins. Analysis of immunoglobulin (Ig) genes enables insight into the B cell progenitor, as Ig somatic hypermutation correlates with antigen-related B cell transit through the germinal center (GC). LÄS MER

  2. 2. The immunoglobulin genes in an Actinopterygian fish, the Siberian sturgeon (Acipenser baeri)

    Författare :Mats Lundqvist; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Immunoglobulin genes; gene organization; transmembrane TM ; comparative immunology; Siberian sturgeon Acipenser baerii ; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; Molecular Immunology; molekylär immunologi;

    Sammanfattning : Characterization of the immunoglobulin (Ig) light (L) and heavy (H) chain genes from the Siberiansturgeon, Acipenser baeri, revealed an Ig structure simhar to the IgM elass of mammals. The serumforms of the sturgeon Ig are tetrameric and dimeric. LÄS MER

  3. 3. The evolutionary study of the immunoglobulin heavy chain genes of a bony fish, rainbow trout (Oncorhynchus mykiss)

  4. 4. Immunoglobulin Gene Analysis in Different B cell Lymphomas : With Focus on Cellular Origin and Antigen Selection

    Författare :Mia Thorsélius; Richard Rosenquist Brandell; Christer Sundström; Anders Rosén; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; B cell lymphoma; Immunoglobulin; V gene; somatic hypermutation; antigen selection; quantitative PCR; Genetik; Clinical genetics; Klinisk genetik;

    Sammanfattning : B cell lymphoma (BCL) comprises a biologically and clinically heterogeneous group of tumors deriving from different stages of B cell development. The immunoglobulin (Ig) variable heavy chain (VH) gene rearrangement is unique for each BCL and can be used to reveal cellular origin, to study signs of antigen selection and to quantify tumor cell load.

  5. 5. 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 :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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.
