C24:0 and C24:1 sphingolipids in cholesterol-containing, five- and six-component lipid membranes
(Nature, 2020-08-24)
The biophysical properties of sphingolipids containing lignoceric (C24:0) or nervonic (C24:1) fatty acyl residues have been studied in multicomponent lipid bilayers containing cholesterol (Chol), by means of confocal ...
Lipid Self-Assemblies under the Atomic Force Microscope
(MDPI, 2021-09-18)
Lipid model membranes are important tools in the study of biophysical processes such as lipid self-assembly and lipid–lipid interactions in cell membranes. The use of model systems to adequate and modulate complexity helps ...
CHO/LY-B Cell Growth under Limiting Sphingolipid Supply: Correlation between Lipid Composition and Biophysical Properties of Sphingolipid-Restricted Cell Membranes
(Wiley, 2021-06)
Sphingolipids (SL) are ubiquitous in mammalian cell membranes, yet there is little data on the behavior of cells under SL- restriction conditions. LY- B cells derive from a CHO linein whichserine palmitoyl transferase ...
Erythrocyte Membrane Nanomechanical Rigidity Is Decreased in Obese Patients
(MDPI, 2022-02-08)
This work intends to describe the physical properties of red blood cell (RBC) membranes in obese adults. The hypothesis driving this research is that obesity, in addition to increasing the amount of body fat, will also ...
Plasma membrane effects of sphingolipid-synthesis inhibition by myriocin in CHO cells: a biophysical and lipidomic study
(Nature Research, 2022)
[EN] Suppression of a specific gene effect can be achieved by genetic as well as chemical methods. Each approach may hide unexpected drawbacks, usually in the form of side effects. In the present study, the specific inhibitor ...
Pb(II) Induces Scramblase Activation and Ceramide-Domain Generation in Red Blood Cells
(Nature Publishing, 2018-05-10)
The mechanisms of Pb(II) toxicity have been studied in human red blood cells using confocal microscopy, immunolabeling, fluorescence-activated cell sorting and atomic force microscopy. The process follows a sequence of ...
Patches and Blebs: A Comparative Study of the Composition and Biophysical Properties of Two Plasma Membrane Preparations from CHO Cells
(MDPI, 2020-04-10)
This study was aimed at preparing and characterizing plasma membranes (PM) from Chinese Hamster Ovary (CHO) cells. Two methods of PM preparation were applied, one based on adhering cells to a poly-lysine-coated surface, ...
