  1. 11. Neuro-immuno-regulation of inflammation in the colonic mucosa : Focus on mast cells and eosinophils in bowel disorders

    Författare :Maria Teresa Casado Bedmar; Åsa Keita; Johan D Söderholm; Marie Carlson; Melanie Gareau; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mast cells; Eosinophils; Vasoactive intestinal polypeptide; Neuro-immune; Intestinal barrier; Irritable bowel syndrome; Inflammatory bowel diseases; Ussing chamber; Advance image analysis;

    Sammanfattning : Intestinal homeostasis is key to control uptake across the mucosa and protect from harmful substances. Disturbances in the bidirectional communication between the gut and the brain are implicated in irritable bowel syndrome (IBS) and inflammatory bowel diseases (IBD), being Crohn’s disease (CD) and ulcerative colitis (UC) the two most common IBD subtypes.

  3. 12. Mast cells in bacterial infections

    Författare :Elin Rönnberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Mast cells are implicated in immunity towards bacterial infection, but the molecular mechanisms by which mast cells contribute to the host response are only partially understood. Previous studies have examined how mast cells react to purified bacterial cell wall components, such as peptidoglycan and lipopolysaccharide. LÄS MER

  4. 13. The Impact of Tryptase and Epigenetic Mechanisms on Mast Cells

    Författare :Sultan Alanazi; Gunnar Pejler; Constantin Urban; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mast cells; mastocytosis; tryptase; histone; DNA; methylation; neutrophil extracellular traps; Immunologi; Immunology;

    Sammanfattning : Mast cells have a large influence on multiple immune-mediated responses, including allergic conditions, and they have been implicated in various diseases such as arthritis and cancer. Mastocytosis is characterized by abnormal mast cell proliferation induced by mutations in KIT, the stem cell factor (SCF) receptor. LÄS MER

  5. 14. Mast Cell Progenitor Trafficking in Allergic Airway Inflammation

    Författare :Joakim Dahlin; Jenny Hallgren; Hans-Reimer Rodewald; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mast cells; mast cell progenitors; allergy; asthma; allergic airway inflammation; IgE; lung; CD11c;

    Sammanfattning : Mast cell progenitors originate from the bone marrow and migrate to the lungs via the blood. During maturation, these cells acquire granules that contain a potent array of bronchoconstrictive mediators. LÄS MER

  7. 15. Mechanisms triggering the recruitment of mast cell progenitors to the lung and regulation of mast cell degranulation

    Författare :Behdad Zarnegar; Jenny Hallgren; Madeleine Rådinger; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mast cells; Mast cell progenitors; Recruitment; Lung; Virus; Influenza; Innate immunity; Poly I:C; IL-33; VAAT; SLC10A4; Degranulation;

    Sammanfattning : Mast cells stem from the bone marrow and migrate via the blood as mast cell progenitors. Upon arrival in peripheral tissues, they develop into mast cells. These rare immune cells have numerous granules that contain large amounts of pro-inflammatory mediators. LÄS MER
