Vesicles with charged domains
(ELSEVIER SCIENCE BV, 2010)
This work summarizes results obtained on membranes composed of the ternary mixture dioleoylphosphatidylglycerol (DOPG), egg sphingomyelin (eSM) and cholesterol (Chol). The membrane phase state as a function of composition ...
Kinetic and mechanistic characterization of the Sphingomyelinases D from Loxosceles intermedia spider venom
(Elsevier B.V., 2006-03-15)
Envenomation by arachnids of the genus Loxosceles leads to local dermonecrosis and serious systemic toxicity mainly induced by sphingomyelinases D (SMase D). These enzymes catalyze the hydrolysis of sphingomyelin resulting ...

Sphingomyelin metabolism is involved in the differentiation of MDCK cells induced by environmental hypertonicity
(American Society for Biochemistry and Molecular Biology, 2015-04)
Sphingolipids (SLs) are relevant lipid components of eukaryotic cells. Besides regulating various cellular processes, SLs provide the structural framework for plasma membrane organization. Particularly, SM is associated ...
The many faces (and phases) of ceramide and sphingomyelin II – binary mixtures
(Springer Verlag, 2017-10)
A rather widespread idea on the functional importance of sphingolipids in cell membranes refers to the occurrence of ordered domains enriched in sphingomyelin and ceramide that are largely assumed to exist irrespective of ...
Isolation and partial purification of a hemolytic sphingomyelin-inhibitable fraction from the sea anemone Anthopleura nigrescens
(2014-03)
Actinoporins are highly hemolytic pore-forming proteins with a molecular mass of around 20 kDa and high affinity for sphingomyelin-containing membranes. On the crude extract of the sea anemone Anthopleura nigrescens, the ...
Alteration of sphingolipids in biofluids: Implications for neurodegenerative Diseases
(Multidisciplinary Digital Publishing Institute, 2019-07-21)
Sphingolipids (SL) modulate several cellular processes including cell death, proliferation and autophagy. The conversion of sphingomyelin (SM) to ceramide and the balance between ceramide and sphingosine-1-phosphate (S1P), ...
