  4. 3. Impact of the upper gut on body fluid regulation and blood pressure in man - potential involvement of a locally expressed renin-angiotensin system

    Författare :Peter Hallersund; Göteborgs universitet; []
    Nyckelord :angiotensin; stomach; duodenum; sodium; salt; diuresis; appetite; gastric bypass; blood pressure;

    Sammanfattning : This thesis explores the role of the upper gut in the regulation of diuresis and blood pressure control in relation to the novel finding of a mucosa-located renin-angiotensin system (RAS). RAS is a regulatory super-system vital for body fluid homeostasis and blood pressure control. LÄS MER

  5. 4. Functional studies of T-cells in rheumatoid arthritis

    Författare :Louise Berg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :T-cells; Rheumatoid arthritis; inflammation; cytokines; collagen type II; immunomodulation;

    Sammanfattning : Rheumatoid arthritis (RA) is a systemic inflammatory disease with autoimmune features primarily affecting the joints. The etiology of RA is largely unknown but involvement of the immune system in the disease process is evident from the infiltration of leukocytes into the joint, and by the production of proinflammatory cytokines, chemokines and proteases, mainly by macrophages.
