Shotgun lipidomics and mass spectrometry imaging unveil diversity and dynamics in lipid composition in Gammarus fossarum

T. Fu, O. Knittelfelder, O. Geffard, Y. Clement, E. Testet, N. Elie, D. Touboul, K. Abbaci, A. Shevchenko, J. Lemoine, A. Chaumot, A. Salvador, D. Degli-Esposti, S. Ayciriex

The paper uses shotgun lipidomics and mass spectrometry imaging to study lipid composition and spatial distribution in Gammarus fossarum, revealing dynamic lipid changes and sulfate-based lipids in oocytes.

A non-canonical lipid droplet metabolism regulates the conversion of alpha-Synuclein to proteolytic resistant forms in neurons of a Drosophila model of Parkinson disease

V. Girard, F. Jollivet, O. Knittelfelder, J.-N. Arsac, G. Chatelain, D. Van den Brink, T. Baron, A. Shevchenko, N. Davoust-Nataf, B. Mollereau

This study shows that lipid droplet proteins interact with alpha-synuclein in Drosophila neurons, promoting its resistance to proteolysis and aggregation, suggesting a role for non-canonical lipid metabolism in Parkinson's disease.

Sterols as dietary markers for Drosophila melanogaster

O. Knittelfelder, E. Prince, S. Sales, E. Fritzsche, T. Woehner, M. Brankatschk, A. Shevchenko

The paper identifies sterol ratios as a marker for dietary shifts in Drosophila melanogaster during cold acclimation, offering a simpler alternative to full lipidome analysis.

Body size-dependent energy storage causes Kleiber’s law scaling of the metabolic rate in planarians

A. Thommen, S. Werner, O. Frank, J. Philipp, O. Knittelfelder, Y. Quek, K. Fahmy, A. Shevchenko, B. M. Friedrich, F. Julicher, J. C. Rink

This study shows Kleiber’s law in planarians arises from size-dependent energy storage, not cellular metabolic rate changes.
