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

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Anna Bas; Marie-Louise Hammarström; Sten Hammarström; Adrian Hayday; [2003]
    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; MEDICINE Microbiology; immunology; infectious diseases Immunology; MEDICIN Mikrobiologi; immunologi; infektionssjukdomar 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

  2. 2. Defence capabilities of human intestinal epithelial cells

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Anna Fahlgren; Sten Hammarström; Marie-Louise Hammarström; Gudmundur Gudmundsson; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; intestine; mucosa; epithelium; antimicrobial; defensins; glycocalyx; ulcerative colitis; Crohn´s disease; celiac disease; Immunologi; MEDICINE Microbiology; immunology; infectious diseases Immunology; MEDICIN Mikrobiologi; immunologi; infektionssjukdomar Immunologi; immunologi; Immunology;

    Sammanfattning : The epithelial cells lining the intestinal mucosa separate the underlying tissue from components of the intestinal lumen. Innate immunity mediated by intestinal epithelial cells (IECs) provides rapid protective functions against microorganisms. Innate immunity also participates in orchestrating adaptive immunity.

  3. 3. Expansion of circulatory Vγ9Vδ2 T cells in tularemia and Pontiac fever, two intracellular bacterial diseases with widely different clinical expression

    Detta är en avhandling från Umeå : Klinisk mikrobiologi

    Författare :Michal Kroca; Dieter Kabelitz; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; Francisella tularensis; Gamma-delta T cell; Legionella; Legionellosis; Lymphocyte; T cell Tularemia; Immunologi; MEDICINE Microbiology; immunology; infectious diseases Immunology; MEDICIN Mikrobiologi; immunologi; infektionssjukdomar Immunologi; immunologi; Immunology;

    Sammanfattning : Although well established that human Vγ9Vδ2 T cells may expand in circulation during intracellular bacterial infections, most underlying studies included only a few cases and only some diseases had been studied so far. In tularemia, a severe invasive disease, only one patient had been described. LÄS MER

  4. 4. Thrombospondin 1, an autocrine regulator in T cell adhesion and migration

    Detta är en avhandling från Umeå : Klinisk mikrobiologi

    Författare :ShuShun Li; Karl-Gösta Sundqvist; Jan Holgersson; Claes Dahlgren; [2005]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; T cell; adhesion; migration; thrombospondin; Immunologi; MEDICINE Microbiology; immunology; infectious diseases Immunology; MEDICIN Mikrobiologi; immunologi; infektionssjukdomar Immunologi; immunologi; Immunology;

    Sammanfattning : Lymphocytes, the principal cells of the immune system, perform the immune function throughout the body by their unique capacity to circulate in blood stream and lymphatic vessels and migrate in lymphoid and non-lymphoid tissues. The mechanisms regulating lymphocyte adhesion and migration, interactions with cells and components within the extracellular matrix are not fully understood. LÄS MER

  5. 5. Neurofilament light as a marker for neurodegenerative diseases

    Detta är en avhandling från Umeå : Klinisk mikrobiologi

    Författare :Niklas Norgren; Torgny Stigbrand; Roland Carlsson; [2004]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; Neurofilament protein; ELISA; Cerebrospinal fluid; Neurodegenerative diseases; Immunologi; MEDICINE Microbiology; immunology; infectious diseases Immunology; MEDICIN Mikrobiologi; immunologi; infektionssjukdomar Immunologi; immunologi; Immunology;

    Sammanfattning : Neurofilaments are the main cytoskeletal constituents in neuronal cells. They are belived to be important for maintaining the structural integrity and calibre of axons and dendrites thereby influencing the conduction velocity of nerve impulses. LÄS MER
