1. Phospholipase A2 in nerve injury and axonal outgrowth
Sammanfattning : This thesis deals with processes coupled to injury in the peripheral nervous system (PNS), with a general aim to investigate the role of phospholipase A2 (PLA2) enzymes in axonal outgrowth. The axonal outgrowth of dorsal root ganglia (DRG) neurons in vitro was reduced by several different inhibitors of PLA2 activity and enhanced by an activator of this enzyme. LÄS MER
2. Signalling to Activation of Cytosolic Phospholipase A2 and Arachidonate Release in Macrophages
Sammanfattning : Eicosanoids include prostaglandins, thromboxanes and leukotrienes, which are arachidonic acid oxygenation products. These lipids make important contributions to the signs and symptoms of inflammatory diseases. LÄS MER
3. On Cholecystokinin and Phospholipase A2 in Insulin Secretion - an Experimental Study With Reference to the Development of Diabetes
Sammanfattning : 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. Molecular targets for glucocorticoids in macrophages: cytosolic phospholipase A2 and cytokine formation
Sammanfattning : 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. LÄS MER
5. Proteoglycans, group IIA phospholipase A2, and lipoproteins.Potential involvement in atherogenesis
Sammanfattning : 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.
