Exploring Polar Headgroup Interactions Between Sphingomyelin and Ceramide with Infrared Spectroscopy
(Nature, 2020-10-19)
Ceramide is a major actor in the sphingolipid signaling pathway elicited by various kinds of cell stress. Under those conditions ceramide (Cer) is produced in the plasma membrane as a product of sphingomyelin (SM) hydrolysis, ...
Autophagy-related proteins: in vitro studies of protein-lipid interactions modulating autophagosome elongation
(2016-03-18)
La autofagia es un proceso catabólico implicado en el desarrollo de un amplio espectro de enfermedades humanas. Se caracteriza por la formación de una estructura de doble membrana denominada autofagosoma, la cual incorpora ...
Membrane lipid modifications and therapeutic effects mediated by hydroxydocosahexaenoic acid on Alzheimer's disease
(Elsevier, 2013-12-27)
[EN] Alzheimer's disease (AD) is a neurodegenerative pathology with relevant unmet therapeutic needs. Both natural aging and AD have been associated with a significant decline in the omega-3 polyunsaturated fatty acid ...
Changes in Membrane Organization upon Spontaneous Insertion of 2‑Hydroxylated Unsaturated Fatty Acids in the Lipid Bilayer
(American Chemical Society, 2014-02-03)
Recent research regarding 2-hydroxylated fatty acids (2OHFAs) showed clear evidence of their benefits in the treatment of cancer, inflammation, and neurodegenerative disorders such as Alzheimer’s disease. Monolayer ...
Mechanism for ESCPE-1 mediated membrane remodelling and cargo selection in endosomal
(2020-10-02)
El reciclaje de proteínas es fundamental para mantener la homeostasis celular. Este trabajo se enfoca en el reciclaje de proteínas que llegan a los endosomas. Allí, las proteínas transmembrana (receptores) son recicladas ...
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 ...
G protein-membrane interactions II: Effect of G Protein-linked Lipids on Membrane Structure and G Protein-membrane Interactions
(Elsevier, 2017-07-03)
[EN] G proteins often bear myristoyl, palmitoyl and isoprenyl moieties, which favor their
association with the membrane and their accumulation in G Protein Coupled Receptor-rich
microdomains. These lipids influence the ...
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 ...
The triacylglycerol, hydroxytriolein, inhibits triple negative mammary breast cancer cell proliferation through a mechanism dependent on dihydroceramide and Akt
(Impact Journals, 2019-04-02)
The plasma membrane is an attractive target for new anticancer drugs, not
least because regulating its lipid structure can control multiple signaling pathways
involved in cancer cell proliferation, differentiation and ...
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 ...
