MetabolomicsLarge neutral amino acid levels tune perinatal neuronal excitability and survival
Surprisingly little is known about the critical metabolic changes that neural cells have to undergo during development and how even mild, temporary shifts in this program can influence brain circuitries and behavior. Inspired by the discovery that mutations in SLC7A5, a transporter of metabolically-...

MetabolomicsHERPES SIMPLEX VIRUS TYPE 1 IMPAIRS DENDRITIC CELL FUNCTION BY REMODELLING NEUTRAL LIPID METABOLISM AND INDUCING LIPID DROPLET ACCUMULATION
Herpes simplex virus type 1 (HSV-1) infects dendritic cells (DCs), professional antigen-presenting cells that initiate and regulate host antiviral responses. HSV-1 infects DCs limiting their maturation, migration to draining lymph nodes and T cell activation capacity, ultimately promotes their apopt...

MetabolomicsIlluminating the dark space of neutral glycosphingolipidome by selective enrichment and profiling at multi-structural levels

Glycosphingolipids (GSLs) are essential components of cell membranes, particularly enriched in the nervous system. Altered molecular distributions of GSLs are increasingly associated with human diseases, emphasizing the significance of lipidomic profiling. Traditional GSL analysis methods are ham...

MetabolomicsAutomated, Parallel Mass Spectrometry Imaging and Structural Identification of Lipids
We report a method that enables automated data-dependent acquisition of lipid tandem mass spectrometry data in parallel with a high-resolution mass spectrometry imaging experiment. The method does not increase the total image acquisition time and is combined with automatic structural assignment. Thi...

MetabolomicsLipids in the escalated host-pathogen arms race

Lipids, fundamental constituents of cell membranes, cellular energy carriers, and signaling molecules, play a pivotal role in the interaction between pathogens and hosts. During microbial infections, lipids not only fuel the activation of the immune system but also, acting as signaling molec...

MetabolomicsMass Spectrometry Imaging of Lipids in a Gut Epithelial Cell Model

Scope: The Caco2/HT29-MTX co-culture system is widely used as a cell model of the intestinal epithelium. Although the gut epithelium plays an important role in the uptake of free fatty acids and the resynthesis of triglycerides, the lipid distribution profile of the two-dimensional co-culture sys...

MetabolomicsLipidFrag: Improving reliability of in silico fragmentation of lipids and application to the Caenorhabditis elegans lipidome
Lipid identification is a major bottleneck in high-throughput lipidomics studies. We combined the in silico fragmentation tool MetFrag with LipidMaps lipid-class specific classifiers which calculate probabilities for lipid class assignments. The LipidFrag approach was then applied to MS/MS spectra o...

ProteomicsIntracellular drug bioavailability: impact of neutral lipids and phospholipids
The intracellular unbound drug concentration (Cu,cell) drives pharmacological and toxicological responses for targets inside cells. We have previously shown that Cu,cell is not always equal to extracellular unbound drug concentrations (e.g. plasma concentrations). However, the underlying mechanisms ...

Cytoplasmic lipid droplets (LDs) are found in all types of plant cells where they are derived from the endoplasmic reticulum (ER) and function as a repository for neutral lipids, as well as serving in lipid remodelling and signalling. However, the mechanisms underlying the formation and functioning ...
