  1. 1. Approaches to analyses of cytotoxic cells. And studies of their role in H. pylori infection

    Författare :Josef Azem; Göteborgs universitet; []
    Nyckelord :Helicobacter pylori; mucosal immunology; stomach; duodenum; asymptomatic; duodenal ulcer; gastric adenocarcinoma; NK cells; T cells; B cells; dendritic cells; cytotoxic;

    Sammanfattning : Helicobacter pylori infection causes chronic gastritis that may progress to peptic ulcers or gastric adenocarcinoma and thereby cause major world-wide health problems. Previous studies have shown that CD4+ T cells and the production of the cytokine IFN- × are important components of the immune response to H. pylori in humans. LÄS MER

  3. 2. Tissue transglutaminase autoantibodies in childhood celiac disease

    Författare :Daniel Agardh; Pediatrisk endokrinologi; []

    Sammanfattning : Celiac disease is a prevalent small bowel disease in children caused by permanent intolerance against gliadin, which is the alcohol-soluble fraction of the cereal protein gluten in wheat, rye and barley. Celiac disease is characterized by an inflammatory infiltrate of CD4+ T lymphocytes in the intestinal mucosa leading to damage of villous structure and loss of absorptive surface. LÄS MER

  4. 3. Lung-resident, M2e-specific CD4 T cells critically protect during influenza infection

    Författare :Ajibola Omokanye; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; influenza; vaccine; universal; heterosubtypic; M2e; CD4; Th17; ThCTL; tissue-resident; cytotoxic; single-cell RNA-seq;

    Sammanfattning : Memory CD4+ T cells are a critical component of the adaptive immune response to fight infection. However, current vaccines against influenza only focus on the other arm of adaptive immunity—triggering B cells to produce antibodies. LÄS MER

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

    Författare :Lukas Cederbom; Immunologi; []
    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

  7. 5. Trafficking of Human Dendritic Cells and B cells in Helicobacter pylori-induced Gastritis

    Författare :Malin Hansson; Göteborgs universitet; []
    Nyckelord :Helicobacter pylori; migration; homing; dendritic cells; B cells; gastric mucosa;

    Sammanfattning : Infection with the bacterium Helicobacter pylori is widespread throughout the world, and is associated with development of gastric and duodenal ulcer disease as well as gastric adenocarcinoma and mucosa associated lymphoid tissue lymphoma. The infection generally leads to a large infiltration of immune cells, among them dendrite cells (DC) and IgA-secreting cells. LÄS MER
