Purification and characterization of mammalian integrins expressed by a rat neuronal cell line (PC12): evidence that they function as alpha/beta heterodimeric receptors for laminin and type IV collagen. [PDF]

open access: yes, 1988
Cells of the rat neuronal line, PC12, adhere well to substrates coated with laminin and type IV collagen, but attach poorly to fibronectin. Adhesion and neurite extension in response to these extracellular matrix proteins are inhibited by Fab fragments ...

Apoptotic signaling through CD95 (Fas/Apo-1) activates an acidic sphingomyelinase. [PDF]

open access: yes, 1994
Intracellular pathways leading from membrane receptor engagement to apoptotic cell death are still poorly characterized. We investigated the intracellular signaling generated after cross-linking of CD95 (Fas/Apo-1 antigen), a broadly expressed cell ...

Cholesterol esterase action on human high density lipoproteins and inhibition studies: detection by MALDI-TOF MS

open access: yesJournal of Lipid Research, 2005
The modification of lipoproteins by lipolytic enzymes such as cholesterol esterase (CEase) is assumed to play an important role in the pathogenesis of atherosclerosis. However, details of the activation and inhibition of CEase are still unknown.

Metabolic perturbations associated with the consumption of a ketogenic medium-chain TAG diet in dogs with idiopathic epilepsy [PDF]

open access: yes, 2018
Consumption of diets containing medium-chain TAG (MCT) has been shown to confer neuroprotective effects. We aim to identify the global metabolic perturbations associated with consumption of a ketogenic diet (medium-chain TAG diet (MCTD)) in dogs with ...

Lipidomics of cellular and secreted phospholipids from differentiated human fetal type II alveolar epithelial cells

open access: yesJournal of Lipid Research, 2006
Maturation of fetal alveolar type II epithelial cells in utero is characterized by specific changes to lung surfactant phospholipids. Here, we quantified the effects of hormonal differentiation in vitro on the molecular specificity of cellular and ...

Viscosity of phosphatidylcholine (lecithin)

open access: yesJournal of Pharmacy and Pharmacology, 1966
AbstractThe viscosities of egg lecithin dispersed in water have been measured by means of a Couette viscometer. The more concentrated dispersions are thixotropic, but below 1·8% w/w of lecithin the sols become Newtonian. From the extrapolated ratio of specific viscosity to volume fraction, the dispersed particles are considered to be of an elongated ...

Anti-inflammatory Effects of Phosphatidylcholine [PDF]

open access: yesJournal of Biological Chemistry, 2007
We recently showed that mucus from patients with ulcerative colitis, a chronic inflammatory disorder of the colon, is characterized by a low level of phosphatidylcholine (PC) while clinical studies reveal that therapeutic addition of PC using slow release preparations is beneficial. The positive role of PC in this disease is still elusive.

Strategies to Improve the Lipophilicity of Hydrophilic Macromolecular Drugs

open access: yesAdvanced Healthcare Materials, EarlyView.
Hydrophilic macromolecular drugs can be successfully lipidized by covalent attachment of lipids, by hydrophobic ion pairing with negatively or positively charged surfactants, and by dry or wet reverse micelle formation. Lipophilicity enhancement of hydrophilic macromolecules has several benefits including stability and bioavailability improvement ...
