  1. 1. Extrathymic T cell receptor gene rearrangement in human alimentary tract

    Författare :Anna Bas; Marie-Louise Hammarström; Sten Hammarström; Adrian Hayday; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; T cell maturation; recombination activating gene; preTα; human intestinal mucosa; intraepithelial lymphocytes; lamina propria lymphocytes; nasopharyngeal tonsil; Immunologi; Immunology; Immunologi; immunologi; Immunology;

    Sammanfattning : T lymphocytes regulate the initiation, duration, and magnitude of adaptive immune responses and function as effector cells in cell mediated immunity. To become immunologically competent they must generate functional antigen receptors. This process takes place in the thymus and requires somatic recombination of T cell receptor (TCR) genes. LÄS MER

  3. 2. Functional collaboration between HLH transcription factors in B cell development

    Författare :Ramiro Gisler; Stamcellscentrum (SCC); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; E47; Early B cell Factor EBF ; Clinical genetics; Klinisk genetik; HLH proteins; transcription factors; gene expression; B cell development; transcription regulation;

    Sammanfattning : The cells in B cell development can be divided into several subgroups or fractions, e.g. early-pro-B-, pro-B, large-pre-B-, small-pre-B-, immature and mature B cells, where the stages reflect the maturity degree of the cells. LÄS MER

  4. 3. Regulation of B cell development by antigen receptors

    Författare :Jannek Hauser; Thomas Grundström; Yuan Zhuang; Umeå universitet; []
    Nyckelord :calcium; calmodulin; e-proteins; E2A; B cell development; antigen receptor signaling; surrogate light chains; RAG; allelic exclusion; V D J recombination; AID; negative feedback regulation; plasma cell differentiation;

    Sammanfattning : The developmental processes of lymphopoiesis generate mature B lymphocytes from hematopoietic stem cells through increasingly restricted intermediates. Networks of transcription factors regulate these cell fate choices and are composed of both ubiquitously expressed and B lineage-specific factors. LÄS MER

  5. 4. Innate and adaptive immunity in childhood celiac disease

    Författare :Göte Forsberg; Marie-Louise Hammarström; Riccardo Troncone; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; immunologi; Immunology;

    Sammanfattning : Celiac disease (CD) is an inflammatory small-bowel enteropathy caused by a permanent intolerance to wheat gluten and related proteins in rye and barley. Even though the disease originate from the small intestine the clinical symptoms varies in affected individuals and are often different in small children compared to adolescents and adults. LÄS MER

  7. 5. Studies on early cellular responses during Epstein-Barr virus infection

    Författare :Xinsong Chen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The human gamma-herpesvirus Epstein-Barr virus (EBV) has been implicated in the pathogenesis of a broad spectrum of lymphoid and epithelial cell malignancies. A characteristic property of the virus is the capacity to establish a non-productive growthpromoting infection in B-lymphocytes. LÄS MER
