Microbial infection causes inflammation which stimulates macrophage functions. One of the inflammatory products, lysophosphatidylcholine (lyso-Pc), can stimulate macrophage activities. Treatment of mice with lyso-Pc enhanced spreading and ingestion activities of peritoneal macrophages. In vitro
OBJECTIVE
Atherosclerosis is an inflammatory condition, and rupture of atherosclerotic plaques is a major cause of cardiovascular disease (CVD). Lysophosphatidylcholine (LPC) is generated in low-density lipoprotein (LDL) during oxidation and/or enzymatic modification and has been implicated in
The atherogenic serum lysophosphatidylcholine (LPC) is known to mediate vascular endothelial responses ranging from upregulation of adhesion molecules and growth factors to secretion of chemokines and superoxide anion. We investigated whether endothelial cells express receptors for LPC, which may
Alteration of membrane phospholipid fatty acid compositions has been shown to be important for leukocyte inflammatory responses. Such modification of the molecular species of these lipid classes requires deacylation and reacylation reactions and for phosphatidylcholines, lysophosphatidylcholine
Lysophosphatidylcholine (lysoPC) is a polar lipid formed in cells and tissues under normal conditions and is known to cause tissue damage in a variety of experimental systems. We have therefore examined the possibility that increased amounts of lysoPC are formed in activated inflammatory cells and
Apolipoprotein-derived peptides have emerged as a potential candidate for the treatment of various inflammatory disease conditions. These peptides bind to pro-inflammatory lipids and inhibit their inflammatory functions. Lysophosphatidylcholine (LPC) is a potent pro-inflammatory lipid and increased
Arachidonic acid, released from PLA(2) hydrolysis of phosphatidylcholine, is converted to pro-inflammatory or anti-inflammatory mediators. Although lysophosphatidylcholine (lysoPC), another product, is known to be pro-inflammatory, the role of polyunsaturated lysoPCs is not clear. Here, we examined
The role of resveratrol (trans-3,5,4'-trihydroxystilbene; RES) in lysophosphatidylcholine (LPC)‑induced injury and inflammation in endothelial cells (regarded as an early event in arteriosclerosis) is unclear. The present study investigated whether RES reduces lactate dehydrogenase (LDH) activity
OBJECTIVE
Lysophosphatidylcholines (lysoPCs) with polyunsaturated acyl chains are known to exert anti-inflammatory actions. 15-Lipoxygeanation is crucial for anti-inflammatory action of polyunsaturated acylated lysoPCs. Here, the anti-inflammatory actions of 1-(15-hydroxyeicosapentaenoyl)-lysoPC
Microalgae have been shown to be excellent producers of lipids, pigments, carbohydrates, and a plethora of secondary metabolites with possible applications in the pharmacological, nutraceutical, and cosmeceutical sectors. Recently, various microalgal raw extracts have been found to have
Lysophosphatidylcholines (lysoPCs) have been known to be bioactive lipid mediators, which take part in various biological and pathological processes. In the present study, we examined the anti-inflammatory actions of 2-docosahexaenoyl lysophosphatidylcholine (2-docosahexaenoyl-lysoPC) in vitro as
Lysophosphatidylcholine (LPC) has been attributed a pro-inflammatory role in atherosclerosis. Cell culture studies have identified stimulation of cytokine expression and chemotaxis by micromolar (muM) concentrations of LPC. In the present study we have investigated if LPC, in similarity with many
Lipids presented by the MHC class I-like molecule, CD1d, are recognized by NK T (NKT) cells, which can be broadly categorized into two subsets. The well-characterized type I NKT cells express a semi-invariant TCR and can recognize both α- and β-linked glycolipids, whereas type II NKT cells are less
Mammalian cell membrane phosphatidylcholines (PCs), the major phospholipids, exhibit diversity which is controlled by Lands' cycle or PC remodeling pathway. Lysophosphatidylcholine acyltransferase (LPCAT) is one of the major players in the pathway and plays an important role in maintaining cell
Tuberculosis is caused by the infectious agent Mycobacterium tuberculosis (Mtb). Mtb has various survival strategies, including blockade of phagosome maturation and inhibition of antigen presentation. Lysophosphatidylcholine (LPC) is a major phospholipid component of oxidized low-density lipoprotein
