New pre-print from the lab! Host lipid droplets coordinate the synthesis of defensive PUFAs and become PUFA reservoirs and suppliers that mediate inflammation, bacterial phagocytosis, and elimination of microbes. Have a look www.biorxiv.org/content/10.6...

Membrane contacts between caveolae and the endoplasmic reticulum regulate uptake and metabolic trapping of long-chain fatty acids The vital process of cellular fatty acid metabolism involves uptake, metabolic trapping and storage of long-chain fatty acids (LCFAs) in different lipid species. Although several different enzymes lik...

Imidazole propionate is a driver and therapeutic target in atherosclerosis - Nature Imidazole propionate produced by gut microbiota is associated with atherosclerosis in mouse models and in humans, and causes the development of atherosclerosis through activation of the imidazoline-1 ...

💥 A gut microbe metabolite that drives #atherosclerosis?
Yes—Imidazole propionate (ImP) triggers vascular inflammation without changing cholesterol.
🧪 We show the pathway—and how to block it.

Triglycerides are an important fuel reserve for synapse function in the brain - Nature Metabolism Kumar et al. show that under glucose-depleted conditions, neurons can use fatty acids as an alternative source of energy to support synaptic function.

Well what do you know!? This might be the most interesting unorthodox orthodox metabolism paper this year.

The #MembraneTrafficking online seminars are back this Thursday (June 26th, 5pm CEST). We'll hear from @jnuechel.bsky.social about how to find the right partner for a TANGO, and from Maohan Su about the organizational principles of the Golgi. @ishier.bsky.social @franbottanelli.bsky.social

Cocrystal structure reveals the mechanism of FSP1 inhibition by FSEN1 | PNAS FSP1 is an FAD-dependent oxidoreductase that uses NAD(P)H to regenerate the reduced forms of lipophilic quinone antioxidants, such as coenzyme Q10 ...

Thrilled this paper is out! We solved the first cocrystal structure of FSP1 with an inhibitor (FSEN1), providing mechanistic insight & a foundation for medchem. Led by Amalia Megarioti & Sitao Zhang. A terrific collaboration with Da Jia.

What an inspiring morning at the CatCat Symposium! Thank you so much for inviting me @gallegolab.bsky.social and @felixmendu.bsky.social, it's been a pleasure visiting you in Barcelona 😊

Pleased to see Kevin's paper on the Retromer complex interaction with yeast Vps5 and Vps17 proteins now online!

We are looking for a PhD candidate starting on the 01-10-2025. The project aims to understand how the host cells use copper and oxidative species to fight Salmonella infection and how this pathogen evades this antimicrobial response.
