The human plasma-metabolome: Reference values in 800 French healthy volunteers; impact of cholesterol, gender and age.

PLoS ONE, 2017
Metabolomic approaches are increasingly used to identify new disease biomarkers, yet normal values of many plasma metabolites remain poorly defined. The aim of this study was to define the "normal" metabolome in healthy volunteers. We included 800 French

Reliability of Serum Metabolites over a Two-Year Period: A Targeted Metabolomic Approach in Fasting and Non-Fasting Samples from EPIC.

PLoS ONE, 2015
ObjectiveAlthough metabolic profiles have been associated with chronic disease risk, lack of temporal stability of metabolite levels could limit their use in epidemiological investigations.

Human Gut Bacteria and Lipidic Nanoparticles: Particle Composition Predicts Structural Transformation and Bacterial Biocompatibility

Advanced Functional Materials, EarlyView.
Lipidic nanoparticles (LNPs) were incubated with 21 gut bacteria frequently associated with the human microbiome. SAXS revealed that ∼75% of tested species induced structural transformations in monoolein LNPs, whereas phytantriol and phospholipid formulations remained unaffected.

Biomembranal Myristoyl-Phosphatidylcholine as a Potential Target of the Cell Injury Activity of Vitamin D Decomposition Products in Eukaryotic Cells

Frontiers in Bioscience-Landmark
Background: Vitamin D decomposition products target a myristic acid sidechain of the predominant glycerophospholipid constructed in the biomembranes of Helicobacter pylori, causing gastric cancer in humans, and disrupt the membrane ...

Improved method for the synthesis of phosphatidylcholines.

Journal of Lipid Research, 1984
An improved method for the synthesis of phosphatidylcholines from phosphatidic acid and choline is described. The technique utilizes the tetraphenylborate salt of choline together with the condensing agent 2,4,6-triisopropylbenzenesulfonyl chloride.

Microfluidic Nano‐Assembly of Red‐Blood‐Cell (RBC) Lipids and Components for Engineering Extracellular Vesicles

Advanced Healthcare Materials, EarlyView.
Engineered red blood cell‐derived extracellular vesicles (eRBCEVs) are synthesized via controlled microfluidic assembly from native RBC lipids, enabling tunable encapsulation of proteins, nucleic acids, nanoparticles, and viral vectors. The platform demonstrates reproducible nanoscale architecture, preserved membrane composition, and functional cargo ...

Mass spectrometry of the phosphatidyl amino alcohols: detection of molecular species and use of low voltage spectra and metastable scanning in the elucidation of structure

Journal of Lipid Research, 1972
The basic fragmentation mechanisms occurring in the mass spectra of the phosphatidylcholines have been described previously, and evidence was adduced to show that many of the more abundant ions are related by electron impact-induced processes.

Structural library and visualization of endogenously oxidized phosphatidylcholines using mass spectrometry-based techniques

Nature Communications, 2021
Oxidized phosphatidylcholines (oxPCs) are a structurally diverse class of lipids associated with various diseases. Here, the authors use mass spectrometry to construct a spectral library of 465 oxPCs and subsequently profile oxPCs formed during ...

Anti-inflammatory Effects of Phosphatidylcholine [PDF]

Journal of Biological Chemistry, 2007
We recently showed that mucus from patients with ulcerative colitis, a chronic inflammatory disorder of the colon, is characterized by a low level of phosphatidylcholine (PC) while clinical studies reveal that therapeutic addition of PC using slow release preparations is beneficial. The positive role of PC in this disease is still elusive.

Gardiquimod Nanoemulsion Targets Cutaneous Leishmaniasis Lesions Reducing Systemic Toxicity and Parasite Burden

Advanced Healthcare Materials, EarlyView.
Nanoemulsion delivery of a TLR7 agonist enhances safety and promotes colocalization with Leishmania‐infected macrophages in skin lesions, enabling a ∼2‐log reduction in parasite burden. However, tissue‐level constraints and TLR‐driven regulatory feedback generate a mixed immune response that limits complete parasite clearance.
