  1. 1. T-cell responses to Helicobacter pylori in humans and a possible role of regulatory T cells

    Författare :Anna Lundgren; Göteborgs universitet.; Gothenburg University.; [2004]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Helicobacter pylori; mucosal immunology; stomach; duodenum; asymptomatic; duodenal ulcer; gastric adenocarcinoma; T cells; regulatory T cells; dendritic cells; T-cell recruitment;

    Sammanfattning : Helicobacter pylori colonize the stomach and areas of gastric metaplasia in the duodenum. The bacteria induce both local and systemic immune responses, but despite this, the infection normally persists for life and causes chronic gastritis in all infected subjects and peptic ulcers or gastric cancer in 10-20% of infected individuals.

  2. 2. T Regulatory Cells – Friends or Foes?

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Camilla Lindqvist; Uppsala universitet.; [2010]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Treg; T regulatory cell; FoxP3; CD25; CLL; B-cell lymphoma; MEDICINE Microbiology; immunology; infectious diseases Immunology Clinical immunology; MEDICIN Mikrobiologi; immunologi; infektionssjukdomar Immunologi Klinisk immunologi; Klinisk immunologi; Clinical Immunology;

    Sammanfattning : T regulatory cells (Tregs) have been extensively studied in patients with cancer or autoimmunity. These cells hamper the immune system’s ability to clear tumor cells in cancer patients. In autoimmune diseases, on the other hand, they are not able to restrain autoreactive immune responses.

  3. 3. Regulatory Immune Responses and Repair Mechanisms in Atherosclerosis

    Detta är en avhandling från Experimental Cardiovascular Research Unit, Lund University

    Författare :Sara Rattik; Lunds universitet.; Lund University.; [2015]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular disease; Atherosclerosis; T helper 2 cells; ApoB100; Regulatory B cells; Regulatory T cells; Smooth muscle cells; IL-22.;

    Sammanfattning : Atherosclerosis is a chronic inflammatory disease characterized by the formation of lipid rich plaques in the arterial wall. Rupture of a plaque results in clinical manifestations such myocardial infarction or stroke. LÄS MER

  4. 4. 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; Lunds universitet.; Lund University.; [2001]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CD152; Immunology; 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

  5. 5. The immortalization process of T cells with focus on the regulation of telomere length and telomerase activity

    Detta är en avhandling från Umeå : Umeå university

    Författare :Sofie Degerman; Umeå universitet.; [2010]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; immortalization; senescence; T cells; Nijmegen breakage syndrome; telomere; telomerase; hTERT; generic aberrations; methylation; MEDICINE; MEDICIN; patologi; Pathology;

    Sammanfattning : Cellular immortalization is a major hallmark of cancer and is a multi-step process that requires numerous cell-type specific changes, including inactivation of control mechanisms and stabilization of telomere length. The telomeres at the chromosome ends are essential for genomic stability, and limit the growth potential of most cells. LÄS MER
