to damaged endomembranes upon detection of sphingomyelin exposure [PDF]

, 2023
Invasive bacteria enter the cytosol of host cells through initial uptake into bacteria‐containing vacuoles (BCVs) and subsequent rupture of the BCV membrane, thereby exposing to the cytosol intraluminal, otherwise shielded danger signals such as glycans ...

Human Plasma Sphingomyelins.

Experimental Biology and Medicine, 1964
SummaryThe sphingomyelin region of human plasma lipids, entirely free from lecithin, has been fractionated into two components by thin-layer chromatography. Both components had properties characteristic of sphingomyelins, but markedly different fatty acid patterns, acids above C20 being concentrated in the less-polar material.

Membrane‐Active Peptide Protects Against Inflammation by Targeting NLRP3 Activation at the Trans‐Golgi Network

Advanced Science, EarlyView.
The membrane‐active peptide Pep19‐2.5 reduces harmful inflammation by blocking activation of the NLRP3 inflammasome at trans‐Golgi network membranes. By targeting key membrane interactions, Pep19‐2.5 suppresses inflammatory IL‐1β production and alleviates allergic airway inflammation in mice, leading to reduced immune cell infiltration and improved ...

Sphingomyelin as a danger signal in cell-autonomous immunity [PDF]

, 2017
Individual cells employ mechanisms of cell-autonomous immunity to defend their cytosol against bacterial invasion. One such mechanism involves indirect detection of the pathogen through recognition of pathogen-induced disturbances causing the appearance ...

CA9‐Targeted PET Imaging for Noninvasive Discrimination of Clear Cell Renal Cell Carcinoma and Associated Tumor Biological Features

Advanced Science, EarlyView.
CA9‐targeted PET imaging could be a noninvasive approach to characterize clear cell renal cell carcinoma and associated tumor biology. PET uptake correlates with tumor CA9 expression and is linked to angiogenic activity, immune remodeling, and metabolic reprogramming.

Sphingolipids in human ileostomy content after meals containing milk sphingomyelin.

, 2010
BACKGROUND: Sphingomyelin occurs in modest amounts in the diet, in sloughed mucosal cells, and in bile. It is digested by the mucosal enzymes alkaline sphingomyelinase and ceramidase. In humans, alkaline sphingomyelinase is also secreted in bile.

Chinese hamster ovary cells overexpressing the oxysterol binding protein (OSBP) display enhanced synthesis of sphingomyelin in response to 25-hydroxycholesterol

Journal of Lipid Research, 1999
25-Hydroxycholesterol negatively regulates cholesterol synthesis and activates cholesterol esterification in a variety of cultured cells. Concurrent with these effects, 25-hydroxycholesterol also stimulates the synthesis of sphingomyelin in Chinese ...

Reorganization of Innate Immune Cell Lipid Profiles by Bioinspired Meroterpenoids to Limit Inflammation

Advanced Science, EarlyView.
Resolution pharmacology is an emerging strategy to tackle inflammatory pathologies. Bioinspired meroterpenoids induce a lipid mediator class switch toward inflammation resolution in vitro and in vivo by targeting key nodes in lipid mediator biosynthesis and neutral lipid dynamics.

Myriocin slows the progression of established atherosclerotic lesions in apolipoprotein E gene knockout mices⃞

Journal of Lipid Research, 2008
The serine palmitoyl transferase inhibitor myriocin potently suppresses the development of atherosclerosis in apolipoprotein E (apoE) gene knockout (apoE−/−) mice fed a high-fat diet.

Lipidomic Profile Reconstruction of Therapeutic Membrane Targets Using Physics‐Based Optimization with Limited Activity Data

Advanced Science, EarlyView.
Using a minimal set of experimentally labeled antimicrobial and non‐antimicrobial peptides, we reconstruct the effective lipid composition of a pathogenic membrane ‐demonstrated at the example of bacterial membranes‐ through a physics‐based evolutionary molecular dynamics (Evo‐MD) approach. Optimization based on peptide insertion reveals broad‐spectrum
