Sphingomyelin metabolism is involved in the differentiation of MDCK cells induced by environmental hypertonicity [PDF]

, 2015
Sphingolipids (SLs) are relevant lipid components of eukaryotic cells. Besides regulating various cellular processes, SLs provide the structural framework for plasma membrane organization.

Discovery of an Adaptive Neuroimmune Response Driving Itch and Fast Tick Removal with Implications for Preventing Pathogen Transmission

Advanced Science, EarlyView.
Itch‐induced tick removal (IITR): An acquired neuroimmune mechanism, itch‐induced tick removal, develops after repeated tick exposure, mobilizing T cells and macrophages at the tick bite site to trigger a rapid scratching response that facilitates timely tick removal within a critical window that preces the transmission of many tick‐borne pathogens ...

Thematic Review Series: Skin Lipids. Antimicrobial lipids at the skin surface

Journal of Lipid Research, 2008
The skin surface represents our interface with the external environment, and as such, is our first line of defense against microbial colonization and infection. Lipids at the skin surface are thought to underlie at least part of an antimicrobial barrier.

A Microbial Lipid‐ATP Synthase Axis Fuels NK Cell Antitumor Activity

Advanced Science, EarlyView.
This study focuses on the mechanism by which gut microbiota‐derived outer membrane vesicles (OMVs) regulate NK cell antitumor activity. B. intestinalis is identified to decrease extra‐intestinal tumor growth via its OMVs enriched in sphingosine (SP).

Intestinal absorption of dietary maize glucosylceramide in lymphatic duct cannulated rats

Journal of Lipid Research, 2010
Sphingolipids are ubiquitous in all eukaryotic organisms. Various physiological functions of dietary sphingolipids, such as preventing colon cancer and improving the skin barrier function, have been recently reported. One of the common sphingolipids used

A Role of Sphingosine in the Intracellular Survival of Neisseria gonorrhoeae

Frontiers in Cellular and Infection Microbiology, 2020
Obligate human pathogenic Neisseria gonorrhoeae are the second most frequent bacterial cause of sexually transmitted diseases. These bacteria invade different mucosal tissues and occasionally disseminate into the bloodstream.

The low intestinal and hepatic toxicity of hydrolyzed fumonisin B1 correlates with its inability to alter the metabolism of sphingolipids [PDF]

, 2012
Fumonisins are mycotoxins frequently found as natural contaminants in maize, where they are produced by the plant pathogen Fusarium verticillioides. They are toxic to animals and exert their effects through mechanisms involving disruption of sphingolipid

Endogenous Ceramide 24:1 Constrains Th17‐Driven Neutrophilic Inflammation by Antagonizing EP2 Signaling

Advanced Science, EarlyView.
Cer24:1 levels are reduced in neutrophilic asthma and inversely correlate with disease severity and airway neutrophilia. Restoring Cer24:1 suppresses pathogenic Th17 differentiation by engaging EP2 on CD4+ T cells, thereby dampening the JAK2–STAT3–RORγt axis and reducing IL‐17 production.

Role of sphingolipid-mediated cell death in neurodegenerative diseases

Journal of Lipid Research, 1998
The metazoan nervous system gives rise intradevelopmentally to many more neurons than ultimately survive in the adult. Such excess cells are eliminated through programmed cell death or apoptosis.

Diastereoselective addition of alkenylchromium(III) reagents to Garner’s aldehyde: Nozaki-Hiyama-Kishi coupling approach to sphingosines and ceramides [PDF]

Journal of the Serbian Chemical Society, 2014
The intermolecular Nozaki-Hiyama-Kishi coupling between alkenylchromium(III) reagents, derived from either (E)-2-bromostyrene or (E)-1-iodopentadec-1-ene, and conformationally rigid Garner's aldehyde resulted in stereoselective formation of ...
