  2. 11. On Cholecystokinin and Phospholipase A2 in Insulin Secretion - an Experimental Study With Reference to the Development of Diabetes

    Author : Erik Simonsson; Malmö Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Type 2 Diabetes; Insulin Resistance; Islet; Beta-cell; Insulin Secretion; Ca2 -Dependency; Intracellular Signalling; Phospholipase A2; Cholecystokinin; Non-glucose Secretagogues; Endocrinology; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi;

    Abstract : In view of unsolved issues regarding cellular events underlying the adaptation of insulin secretion to insulin resistance, together with the observation that insulin secretion induced by the gastrointestinal hormone and neuropeptide cholecystokinin (CCK) is not solely explained by phospholipase C-protein kinase C (PLC-PKC) pathway activation, this study aimed at delineate mechanisms responsible for the hyperinsulinemia in insulin resistance, with particular attention paid to the action of glucose vs. non-glucose secretagogues, such as CCK.

  4. 12. Molecular targets for glucocorticoids in macrophages: cytosolic phospholipase A2 and cytokine formation

    Author : Karin Gewert; Infektionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacognosy; Pharmacological sciences; signal transduction; dexamethasone; cytosolic phospholipase A2; glucocorticoids; macrophages; protein kinase C; mitogen-activated protein kinases; TNF-alpha; IL-1beta; protein phosphatases; okadaic acid; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi;

    Abstract : The aim of this investigation has been to study mechanisms by which glucocorticoids inhibit inflammatory processes in vitro. Type IV cytosolic 85 kDa phospholipase A2 (cPLA2) is an important modulator of inflammatory responses that is present in macrophages as well as in other cell types. READ MORE

  5. 13. Proteoglycans, group IIA phospholipase A2, and lipoproteins.Potential involvement in atherogenesis

    Author : Peter Sartipy; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; atherosclerosis; group IIA phospholipase A2; proteoglycans; lipoproteins; inflammation;

    Abstract : Atherosclerosis is a multifactorial complex disease characterized by a focal accumulation of ApoB-100 containing lipoproteins, extracellular matrix (ECM), and cells in the arterial intima accompanied by an inflammatory reaction. In vivo and in vitro data supports the hypothesis that sulfated extracellular proteoglycans may be responsible for the selective retention of low density lipoproteins (LDL) in the arterial wall.

  6. 14. Studies on the assembly of cytosolic lipid droplets. Importance of Phospholipase D and ADRP in the process

    Author : Denis Marchesan; Göteborgs universitet; []
    Keywords : Lipid droplets; triglycerides; caveolin; Phospholipase D PLD ; adipocyte differentiation related protein ADRP ; EGCG;

    Abstract : The storage of triglycerides in cells such as adipocytes, liver or muscle cells is of great physiological importance, having implications for our most important metabolic diseases such as obesity, the metabolic syndrome and type II diabetes. A common denominator in these diseases is the insulin resistance, which is also highly related to the production of atherogenic lipoproteins and the development of atherosclerosis and consequently cardio-vascular diseases.

  7. 15. 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
