Lysophosphatidic acid as a lipid mediator with multiple biological actions.
Lysophosphatidic acid (LPA) is one of the simplest glycerophospholipids with one fatty acid chain and a phosphate group as a polar head. Although LPA had been viewed just as a metabolic intermediate in de novo lipid synthetic pathways, it has recently been paid much attention as a lipid mediator. LPA exerts many kinds of cellular processes, such as cell proliferation and smooth muscle contracti...
متن کاملRegulation of angiogenesis by phospholipid lysophosphatidic acid.
Lysophosphatidic acid (LPA) as a bioactive phospholipid signaling mediator is emerging as an important regulator of endothelial cell functions and angiogenesis. Many studies have shown that LPA is an active player in regulating the processes of endothelial cell migration, proliferation, and differentiation, all essential in angiogenesis. Through modulating angiogenesis associated gene expressio...
متن کاملLysophosphatidic acid is a potential mediator of cholestatic pruritus.
BACKGROUND & AIMS Pruritus is a common and disabling symptom in cholestatic disorders. However, its causes remain unknown. We hypothesized that potential pruritogens accumulate in the circulation of cholestatic patients and activate sensory neurons. METHODS Cytosolic free calcium ([Ca(2+)](i)) was measured in neuronal cell lines by ratiometric fluorometry upon exposure to serum samples from p...
متن کاملLysophosphatidic acid as a mediator for proinflammatory agonists in a human corneal epithelial cell line.
Lysophosphatidic acid (LPA) refers to a family of small phospholipid mediators that are generated in response to agonist stimulation in diverse cell types. LPA binds to G protein-coupled receptors to elicit numerous biological responses, including proliferation and inflammation. In this study, LPA production and response were characterized in a human corneal epithelial cell line, 2.040 pRSV-T. ...
متن کاملLysophosphatidic acid synthesis and release.
Lysophosphatidic acid (LPA) is a bioactive phospholipid controlling numerous cellular responses through the activation of specific G-protein coupled transmembrane receptors. LPA is present in several biological fluids (serum, plasma, aqueous humor) and can be secreted by several cell types (platelets, fibroblasts, adipocytes, cancer cells). Whereas, multiple pathways of synthesis and degradatio...
