Bacterial and viral respiratory tract infections result in millions of deaths worldwide and are currently the leading cause of death from infection. Acute inflammation is an essential element of host defense against infection, but can be damaging to the host when left unchecked. Effective host
Since the discovery that Greenlandic Innuits had a lower risk of developing cardiovascular diseases (CVD) due to their diet of fish and as a consequence high polyunsaturated fatty acids (PUFA) intake, scientific interest in the therapeutic value of n-3 PUFA such as eicosapentaenoic acid (EPA) and
The enzyme phospholipase A2 (PLA2) is overexpressed in the inflamed intestine in inflammatory bowel disease (IBD) patients, and in this work we aimed to exploit PLA2 as a prodrug-activating enzyme for a novel PL-drug conjugate, thereby liberating the free drug specifically in the targeted diseased
Phospholipid transfer protein (PLTP) facilitates the transfer of phospholipids from triglyceride-rich lipoproteins into HDL. PLTP has been shown to be an important factor in lipoprotein metabolism and atherogenesis. Here, we report that chronic high-fat, high-cholesterol diet feeding markedly
Arachidonic acid (AA) metabolism and phospholipase A2 (PLA2) activity were measured in the peripheral blood polymorphonuclear leukocytes (PMNL) from ten patients with rheumatoid arthritis (RA) on treatment with various non-steroidal anti-inflammatory agents (NSAIA). AA metabolism and PLA2 activity
Phospholipid metabolism in inflamed tissue of the mouse skin which had been induced by the application of 1-chloro-2, 4-dinitrobenzene (DNCB), croton oil, or irradiation of ultraviolet rays was examined, and it was found that phospholipid levels had increased in theinflamed tissues. In the case of
OBJECTIVE
To highlight some of the recent advances related to the control of polyunsaturated fatty acid (PUFA) incorporation and remodeling in membrane glycerophospholipids in inflammatory cells.
RESULTS
Several enzymes have recently been identified that are associated with the control of PUFA
Nitro-fatty acids (NO2 -FA) have been widely studied with regard to their identification, structural characterization, and biological actions. NO2 -FA could also be present endogenously esterified to phospholipids (PL), and NO2 -PL were already detected in cardiac mitochondria from diabetic rats and
Atherosclerosis has an underlying inflammatory component. Oxidation of low-density lipoprotein (LDL) particles to modified forms promotes atherogenesis by supplying cholesterol and through the oxidative generation of agents that activate macrophages, smooth muscle and endothelial cells. A primary
The expression of interleukin-1beta (IL-1beta) messenger RNA (mRNA) in macrophage-like cells cultured on phospholipid polymers was evaluated to determine the extent of the inflammatory response. As phospholipid polymers, poly(2-methacryloyloxyethyl phosphorylcholine(MPC)-co-n-butyl
Glycerokinase, glycerophosphate dehydrogenase, glycerophosphate acyltransferase activity, glycerophosphate, dioxiacetonphosphate level and in vivo incorporation of (U-14C)-glucose into the lung phospholipid structure were studied in normal rats and in conditions of chronic bronchopulmonary
Anti-phospholipid syndrome (APS) is defined by recurrent arterial/venous thrombosis and/or fetal losses in the persistent presence of anti-phospholipid antibodies (aPL). In in vivo experimental models aPL thrombogenic activity is associated with a pro-inflammatory endothelial phenotype (increased
Phospholipid transfer protein (PLTP) transfers phospholipids between lipoproteins, and plays an essential role in HDL metabolism. The regulation of PLTP is poorly understood and recent evidence suggests that PLTP activity increases during acute-phase response. Since type 2 diabetes is associated
Chronic inflammatory diseases including atherosclerosis are major causes of morbidity and mortality worldwide. However, the factors, which trigger processes that determine the outcome of an inflammatory response, are still poorly understood. Accumulating evidence suggests that certain lipid
Inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn disease (CD), is a disorder characterized by diffuse inflammation of the gastrointestinal tract. The immune response and inflammation are mediated by polyunsaturated fatty acids and influenced by dietary fats and lipid
