Effect of cholesterol on the surface polarity and hydration of lipid interphases as measured by Laurdan fluorescence: New insights
(Elsevier Science, 2019-06)
Comparison of the behavior of Laurdan in gel and in the liquid crystalline DPPC bilayers with that observed in chloroform and OctOH allow concluding that changes in the membrane lipid order cannot be ascribed to changes ...
Nuclear lipid droplets: a novel nuclear domain
(Elsevier Science, 2013-02)
We investigated nuclear neutral-lipid (NL) composition and organization, as NL may represent an alternative source for providing fatty acids and cholesterol (C) to membranes, signaling paths, and transcription factors in ...
Time-resolved fluorescence and anisotropy-sensitive 1,2-dimyristoyl-sn-glycero-3-(7-aminocoumarin) phosphoetanolamide probe for studying membrane lipid domains
(ELSEVIER SCI LTD, 2023)
A fluorescent probe C-DMPE was synthesised to monitor interfacial membrane properties by conjugating coumarin-343 and 1,2-dimyristoyl-sn-glycero-3-phosphorylethanolamine (DMPE), anchoring the 7-aminocou-marin moiety close ...
N-terminal acetylation of a mastoparan-like peptide enhances PE/PG segregation in model membranes
(2020-10-01)
The synthetic peptides L1A and its acetylated analog (acL1A) display potent Gram-negative bactericidal activities without being hemolytic. We have gathered evidence that the N-terminal acetylation of L1A enhances the lytic ...
Evidence of tryglyceride-phase incorporation into artificial bilayers for studying lipid droplets biogenesis
(Sociedad Argentina de Biofísica, 2018)
Lipid Droplets (LD) are intracelular structures consisting on an apolar lipid core - composed mainly of triglycerides (TG) and steryl esters- which is surrounded by a phospholipid and protein monolayer. LDs originate in ...
Labaditin, a cyclic peptide with rich biotechnological potential: preliminary toxicological studies and structural changes in water and lipid membrane environment
(Springer, 2011-01-01)
Cyclic peptides isolated from the plants of the Euphorbiaceae family have been largely studied due to their rigid conformation, which is considered significant for biologic activity. The peptide Labaditin (L(0)) and its ...
