  2. 6. Phospholipase A2 expression in the human nasal mucosa

    Author : John Lindbom; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Phospholipase A2 (PLA2) is a superfamily of enzymes that play a key role in inflammation by releasing arachidonic acid for the synthesis of eicosanoids and lysophospholipid for the synthesis of platelet-activating factor (PAF). On the other hand, several members of the PLA2 family (VIIA, VIIB, VIIIA and VIIIB) are able to degrade PAF and are therefore potentially important anti-inflammatory enzymes. READ MORE

  4. 7. Phospholipase A2 expression in the human nasal mucosa

    Author : John Lindbom; Roger Sundler; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Phospholipase A2 (PLA2) is a superfamily of enzymes that promote inflammation by releasing arachidonic acid for the synthesis of eicosanoids and lysophospholipid for the synthesis of platelet-activating factor (PAF). On the other hand, several members of the PLA2 family (VIIA, VIIB, VIIIA and VIIIB) are able to degrade PAF and are therefore potentially important anti-inflammatory enzymes. READ MORE

  5. 8. Enzymatic Synthesis of Mixed Acid Phospholipids

    Author : Dietlind Adlercreutz; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lysophosphatidylcholine; phosphatidylcholine; acyl migration; equilibrium; organic solvent; lipase; phospholipase; Biotechnology; Bioteknik;

    Abstract : Mixed acid phospholipids are valuable compounds, which are used mainly in membrane- and lipoprotein research and in liposome technology. The chemical synthesis of these special lipids is rather difficult and involves both toxic chemicals and harsh reaction conditions, which makes the products less attractive for medical and biological applications.

  6. 9. OX1 Orexin Receptor Signalling to Phospholipases

    Author : Marie Ekholm; Jyrki Kukkonen; Graeme Milligan; Uppsala universitet; []
    Keywords : orexin; phospholipase; Calcium; cell signalling; G protein coupled receptor; ERK; live-cell imaging; arachidonic acid; diacylglycerol;

    Abstract : The neuropeptides orexin-A and orexin-B were discovered in 1998 and were first described as regulators of feeding behaviour. Later research has shown that they have an important role in the regulation of sleep. Two G protein-coupled receptors, OX1 and OX2 orexin receptors, mediate the cellular responses to orexins.

  7. 10. Studies of prostaglandin E2 formationin human monocytes

    Author : Sofia Karlsson; Jonny Wijkander; Christina Gustafson-Svärd; Karlstads universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE
