Imaging the early stages of phospholipase C/sphingomyelinase activity on vesicles containing coexisting order-disorder and gel-fluid domains
(Elsevier, 2011-04)
[EN] The binding and early stages of activity of a phospholipase C/sphingomyelinase from Pseudomonas aeruginosa on giant unilamellar vesicles (GUV) have been monitored using fl uorescence confocal microscopy. Both the ...
Accumulated Bending Energy Elicits Neutral Sphingomyelinase Activity in Human Red Blood Cells
(Elservier, 2012-05-02)
[EN] We propose that accumulated membrane bending energy elicits a neutral sphingomyelinase (SMase) activity in human erythrocytes. Membrane bending was achieved by osmotic or chemical processes, and SMase activity was ...
Human ATG3 binding to lipid bilayers: role of lipid geometry, and electric charge
(Nature Publishing, 2017-11-15)
Specific protein-lipid interactions lead to a gradual recruitment of AuTophaGy-related (ATG) proteins to the nascent membrane during autophagosome (AP) formation. ATG3, a key protein in the movement of LC3 towards the ...
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 ...
Mixing brain cerebrosides with brain ceramides, cholesterol and phospholipids
(Nature Publishing, 2019-09-16)
The properties of bilayers composed of pure brain cerebroside (bCrb) or of binary mixtures of bCrb with brain ceramide, cholesterol, egg phosphatidylcholine or brain sphingomyelin have been studied using a combination of ...
