Sphingolipid and ceramide homeostasis : potential therapeutic targets [PDF]

open access: yes, 2012
Sphingolipids are ubiquitous in eukaryotic cells where they have been attributed a plethora of functions from the formation of structural domains to polarized cellular trafficking and signal transduction.

The Equilibria of Sphingolipid-Cholesterol and Sphingolipid–Sphingolipid in Monolayers at the Air–Water Interface [PDF]

open access: yesThe Journal of Membrane Biology, 2012
Monolayers of sphingomyelin (SM), ceramide (Cer) and cholesterol (Ch) and binary mixtures SM-Ch, SM-Cer and Cer-Ch were investigated at the air-water interface. SM, Cer and Ch were used in the experiment. The surface tension values of pure and mixed monolayers were used to calculate π-A isotherms.

Sphingolipids in mitochondria—from function to disease

open access: yesFrontiers in Cell and Developmental Biology, 2023
Sphingolipids are not only structural components of cellular membranes but also play vital roles in cell signaling and modulation of cellular processes. Within mitochondria, sphingolipids exert diverse effects on mitochondrial dynamics, energy metabolism,

Click-correlative light and electron microscopy (click-AT-CLEM) for imaging and tracking azido-functionalized sphingolipids in bacteria

open access: yesScientific Reports, 2021
Sphingolipids, including ceramides, are a diverse group of structurally related lipids composed of a sphingoid base backbone coupled to a fatty acid side chain and modified terminal hydroxyl group.

Sphingolipids: towards an integrated view of metabolism during the plant stress response [PDF]

open access: yes, 2019
Plants exist in an environment of changing abiotic and biotic stresses. They have developed a complex set of strategies to respond to these stresses and over recent years it has become clear that sphingolipids are a key player in these responses ...

Sphingolipids in mitochondria [PDF]

open access: yesBiochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2017
Sphingolipids are bioactive lipids found in cell membranes that exert a critical role in signal transduction. In recent years, it has become apparent that sphingolipids participate in growth, senescence, differentiation and apoptosis. The anabolism and catabolism of sphingolipids occur in discrete subcellular locations and consist of a strictly ...

Genetic Determinants of Circulating Sphingolipid Concentrations in European Populations [PDF]

open access: yes, 2009
Sphingolipids have essential roles as structural components of cell membranes and in cell signalling, and disruption of their metabolism causes several diseases, with diverse neurological, psychiatric, and metabolic consequences.

Lipidomics Analysis of Outer Membrane Vesicles and Elucidation of the Inositol Phosphoceramide Biosynthetic Pathway in Bacteroides thetaiotaomicron

open access: yesMicrobiology Spectrum, 2022
Approximately one-third of the human colonic microbiome is formed by bacteria from the genus Bacteroides. These bacteria produce a large amount of uniformly sized outer membrane vesicles (OMVs), which are equipped with hydrolytic enzymes that play a role

Serum sphingolipids level as a novel potential marker for early detection of human myocardial ischaemic injury [PDF]

open access: yes, 2013
BACKGROUND: Ventricular tachyarrhythmias are the most common and often the first manifestation of coronary heart disease and lead to sudden cardiac death (SCD).
