1. 1. Phospholipase A2 in nerve injury and axonal outgrowth

   Författare :Marie Hornfelt; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Neurology; cell death; apoptosis; leukotrienes; arachidonic acid; M-type receptor; secretory phospholipase A2; cytosolic phospholipase A2; sciatic nerve; dorsal root ganglia; growth cone; axonal outgrowth; nerve injury; peripheral nerve regeneration; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; Animal physiology; Djurfysiologi;

   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

3. 2. Signalling to Activation of Cytosolic Phospholipase A2 and Arachidonate Release in Macrophages

   Författare :Gösta Hiller; Infektionsmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; signal transduction; dexamethasone; macrophages; phospholipase C; phosphatidylinositol 3-kinase; mitogen-activated protein kinases; cytosolic phospholipase A2; arachidonic acid; Histology; cytochemistry; histokemi; cytokemi; tissue culture; Histologi; vävnadskultur; histochemistry;

   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

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

   Författare :Karin Gewert; Infektionsmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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;

   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. 4. Phospholipase A2 expression in the human nasal mucosa

   Författare :John Lindbom; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : 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. LÄS MER

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

   Författare :John Lindbom; Roger Sundler; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : 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. LÄS MER
