    Författare :Anu S. Helin; Jonas Waldenström; Edwin Veldhuizen; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Avian β-defensins AvBDs ; Avian gene expression; Host-pathogen interactions; Innate immunity; Mallard Anas platyrhynchos ; Myxovirus resistance gene Mx ; Retinoic acid inducible gene 1 RIG-I ; Avian β-defensins AvBD ; Genuttryck; Gräsand Anas platyrhynchos ; Immunförsvar; Immungener; Myxovirus resistant gene Mx ; Patogen; Retinoic acid inducible gene 1 RIG-I ; Ecology; Ekologi;

    Sammanfattning : This thesis comprises two sections, both of which explore eco-immunology of the innate immune system of mallards (Anas platyrhynchos). The innate immune system serves a pivotal role as the first line of defense against invading pathogens, and is comprised of physical and chemical barriers. LÄS MER

  3. 2. Secretory and anti-inflammatory actions of some gastro-intestinal hormones in salivary glands

    Författare :Hülya Çevik Aras; Göteborgs universitet; []
    Nyckelord :salivary glands; protein secretion; synthesis; inflammation; β-defensins; myeloperoxidase; cholecystokinin; gastrin; melatonin; nitric oxide; nerve stimulation;

    Sammanfattning : Textbooks generally state that the secretory activity of salivary glands is solely regulated by nerves. This view is challenged in the present Thesis, using the parotid gland of the anaesthetized rat as experimental in vivo model. LÄS MER

  4. 3. Defensins and cytokines in inflammatory bowel disease

    Författare :Arman Rahman; Mats Andersson; Umeå universitet; []
    Nyckelord :immunologi; Immunology;

    Sammanfattning : Ulcerative colitis (UC) and Crohn’s disease (CD) constitute the two major inflammatory bowel diseases in man. Both are serious chronic illnesses of the intestine with severe debilitating effects. The etiology of the diseases is unknown, but involvement of both adaptive and innate immune reactions seems to be major factors in the pathogenesis. LÄS MER

  5. 4. Human vaginal epithelial immunity and influences of hormonal contraceptive usage

    Författare :Anna Ildgruben; Nils Lycke; Umeå universitet; []
    Nyckelord :human vaginal epithelium; hormonal contraceptives; epithelial thickness; intraepithelial immune cells; steroid receptors; steroid hormones; defensins; obstetrik och gynekologi; Obstetrics and Gynaecology;

    Sammanfattning : The vagina is the port of entry for sexually transmitted diseases in women. Its epithelium constitutes the luminal border, thus comprising an important defence barrier. LÄS MER
