  1. 1. The ups and downs of T cells The role of costimulatory molecules in the modulation of T cell responses

    Detta är en avhandling från Christina Olsson, Broddarp 7, 235 94 Vellinge

    Författare :Christina Olsson; Lund University.; Lunds universitet.; [2000]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunologi; transplantation; serology; CD28; costimulation; CD152; IL-2; NF-kB; AP-1; superantigen; Immunology; T cell; serologi;

    Sammanfattning : T cell activation requires the combination of antigen in the context of MHC and costimulatory molecules to induce a functional immune response. For our studies, we primarily utilized superantigens (SAg) that bind MHC class II molecules as first signal. LÄS MER

  2. 2. Studies on the function of CD4CD25 regulatory T cells: An in vitro approach

    Detta är en avhandling från Section for Immunology, Lund University

    Författare :Lukas Cederbom; Lund University.; Lunds universitet.; [2001]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; CD152; Costimulation; Dendritic cells; Regulatory T cells; CD4 CD25 ; serology; transplantation; Immunologi; serologi;

    Sammanfattning : Immunological self-tolerance is a state of the whole organism where deleterious responses are either avoided or regulated. Breaking of immunological tolerance will lead to autoimmune disease or chronic inflammatory conditions. LÄS MER

  3. 3. T cells and costimulatory factors in myasthenia gravis

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Medicine

    Författare :Maria Kakoulidou; Karolinska Institutet.; Karolinska Institutet.; [2005]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; T cells; Myasthenia gravis MG ; costimulation; autoimmune disease; genetic polymorphism; twin;

    Sammanfattning : The autoimmune disease myasthenia gravis (MG) is characterized by muscle weakness due to a loss of acetylcholine receptors (AChR) at the neuromuscular end plate. Most MG patients have pathogenic antibodies directed against the receptor. We provide further evidence that T cells are important for establishment and continuation of the disease. LÄS MER

  4. 4. Modulation of Autoimmunity by Linomide treatment or interference with costimulation

    Detta är en avhandling från Annamaria Tellander, Karl XII gatan 8a, 222 20 Lund, Sweden

    Författare :Annamaria C Tellander; Lund University.; Lunds universitet.; [2000]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oncology; Cytology; collagen-induced arthritis; CD28; CD40; antigen presenting cells; Linomide; thymocytes; cancerology; Cytologi; onkologi; cancer;

    Sammanfattning : Linomide is a potent immunomodulator that has been shown to inhibit autoimmunity in several animal models of autoimmune disease. We have approached the cellular and molecular mechanism of Linomide by investigating its effect on thymocyte development and its capacity to modulate the expression of activation markers on antigen presenting cells (APCs).

  5. 5. Inhibition of T cell responses to autoantigens and allergens by CD25+ regulatory T cells from thymus, cord and adult blood

    Detta är en avhandling från Annamaria Tellander, Karl XII gatan 8a, 222 20 Lund, Sweden

    Författare :Kajsa Wing; Göteborgs universitet.; Gothenburg University.; [2004]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tolerance; CD25 regulatory T cells; adult peripheral blood; cord blood; thymus; autoimmune disease; allergy;

    Sammanfattning : Autoimmune diseases and allergies are a growing problem in the western world today. Tolerance is primarily established by clonal deletion in the thymus. Despite this auto-reactive T cells are normally present in most individuals, which suggests that mechanisms of peripheral tolerance operate to silence potentially pathogenic T cells. LÄS MER
