  1. 1. Characterisation of CD8 T cells in mucosa associated lymphoid tissue : implications for immune control of HIV-1 infection

    Författare :Máire Quigley; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :CD8 T cells; Human Immunodeficiency Virus-1; Mucosa Associated Lymphoid Tissue; perforin; cytotoxicity; gastrointestinal mucosa; tonsil; CD7 expression; Simian Immunodeficiency Virus.;

    Sammanfattning : The role of CD8 T cells has been implicated in the partial immune control of HIV-1 infection. Ultimately these cells fail to control the infection and immune deficiency ensues in the absence of antiretroviral therapy. LÄS MER

  3. 2. 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

  4. 3. 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

  5. 4. Long-wave ultraviolet radiation (UVA1) and visible light : therapeutic and adverse effects in human skin

    Författare :Desiree Wiegleb Edström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Ultraviolet-A; visible light; p53; p21WAF-1; bcl-2; CD34; port-wine stains; mycosis fungoides; dye laser; photodynamic therapy.;

    Sammanfattning : We studied the effects of repetitive low-dose UVA1 radiation and visible light in normal sunshielded skin, using immunohistochemical staining for p53, p21WAF-1, bcl-2, Ki67 and cyclin A. An increased expression of Ki67 after UVA1 and visible light were observed as a sign of increased proliferation. LÄS MER
