  1. 1. Studies of prostaglandin E2 formationin human monocytes

    Författare :Sofia Karlsson; Jonny Wijkander; Christina Gustafson-Svärd; Karlstads universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prostaglandin E2; arachidonic acid; phospholipase A2; cyclooxygenase; prostaglandin E synthase; human monocytes; Medical cell biology; Medicinsk cellbiologi; Biomedical Sciences; Biomedicinsk vetenskap;

    Sammanfattning : Prostaglandin (PG) E2 is an eicosanoid derived from the polyunsaturated twenty carbon fatty acid arachidonic acid (AA). PGE2 has physiological as well as pathophysiological functions and is known to be a key mediator of inflammatory responses. LÄS MER

  2. 2. Prostaglandin E2 in Brain-mediated Illness Responses

    Författare :Louise Elander; Anders Blomqvist; Marianne Schultzberg; Linköpings universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prostaglandin e2; PGE2; cox-1; cox-2; mPGES-1; fever; anorexia; food intake; HPA-axis; EP-receptor; LPS; IL-1; IL-6; MEDICINE; MEDICIN; Neurobiology; Neurobiologi;

    Sammanfattning : We are unceasingly exposed to potentially harmful microorganisms. The battle against threatening infectious agents includes activation of both the innate and of the adaptive immune systems. LÄS MER

  3. 3. Prostaglandin E2 in immune-to-brain signaling

    Författare :David Engblom; Tamas Bartfai; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Upon immune-challenge, signaling from the immune system to the brain triggers an array of central nervous responses that include fever, anorexia, hyperalgesia and activation of the hypothalamus-pituitary adrenal axis. These symptoms are dependent on cytokines produced at the site of inflammation. LÄS MER

  4. 4. Cell signalling in cancer. A functional and immunochemical investigation of purinergic,adrenergic, nitrergic, and prostaglandin mediated signalling mechanisms in experimental and human cancer

    Författare :Gunnar Nylund; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :; adenosine-5´-triphosphate; colon cancer; extracellular acidification; melanoma; microphysiometer; nitric oxide; noradrenaline; prostaglandin E2; sarcoma; tumour cell; metabolism; uridine-5´-triphosphate;

    Sammanfattning : Disturbed cell signalling is a hallmark of the cancer cell, being one important mechanismbehind uncontrolled cell growth. In the current study, we have investigated cancer cellsignalling with the focus on some first messenger and/or their receptors, in the murine celllines, MCG 101, and K1735-M2, and the human colon cancer cell line, HT-29.

  5. 5. Regulation of prostaglandin E2 synthesis in human gingival fibroblasts

    Författare :Tülay Yucel-Lindberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :prostaglandin E2; cyclooxygenase; phospholipase A2 interleukin-1; tumor necrosis factor [alpha]; epidermal growth factor; protein kinase C; tyrosine kinases; human gingival fibroblasts;

    Sammanfattning : Prostaglandins, especially, prostaglandin E2 (PGE2) play an important role in inflammatory diseases such as rheumatoid arthritis and periodontitis. The aim of the present thesis was to study the production and the regulation of PGE2 with special reference to the key enzymes phospholipase A2 (PLA2) and cyclooxygenase (COX) at the rnRNA level in human gingival fibroblasts.
