Role of phospholipid oxidation products in atherosclerosis.
There is increasing clinical evidence that phospholipid oxidation products (Ox-PL) play a role in atherosclerosis. This review focuses on the mechanisms by which Ox-PL interact with endothelial cells, monocyte/macrophages, platelets, smooth muscle cells, and HDL to promote atherogenesis. In the past few years major progress has been made in identifying these mechanisms. It has been recognized t...
متن کاملThermodynamics of phospholipid self-assembly.
Negatively charged phospholipids are an important component of biological membranes. The thermodynamic parameters governing self-assembly of anionic phospholipids are deduced here from isothermal titration calorimetry. Heats of demicellization were determined for dioctanoyl phosphatidylglycerol (PG) and phosphatidylserine (PS) at different ionic strengths, and for dioctanoyl phosphatidic acid a...
متن کاملMolecular Dynamics Simulations on Phospholipid Membranes
Phospholipids are the main components of cell membranes, lipoproteins and other membrane structures in living organisms. Properties of lipid molecules are important to the overall behaviour and interactions of membranes. Furthermore, characteristics of the biological membranes act as important regulators of membrane functions. Molecular dynamics (MD) simulations were applied in this thesis to s...
متن کاملSpontaneous Assembly of Pore Complex-containing Membranes
Extract prepared from activated Xenopus eggs is capable of reconstituting nuclei from added DNA or chromatin. We have incubated such extract in the absence of DNA and found that numerous flattened membrane cisternae containing densely spaced pore complexes (annulate lamellae) formed de novo. By electron and immunofluorescence microscopy employing a pore complex-specific antibody we followed the...
متن کاملEquation of State for Phospholipid Self-Assembly.
Phospholipid self-assembly is the basis of biomembrane stability. The entropy of transfer from water to self-assembled micelles of lysophosphatidylcholines and diacyl phosphatidylcholines with different chain lengths converges to a common value at a temperature of 44°C. The corresponding enthalpies of transfer converge at ∼-18°C. An equation of state for the free energy of self-assembly formula...
