Wnt-controlled sphingolipids modulate Anthrax Toxin Receptor palmitoylation to regulate oriented mitosis in zebrafish

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami

Oriented cell division is a fundamental mechanism to control asymmetric stem cell division, neural tube elongation and body axis extension, among other processes. During zebrafish gastrulation, when the body axis extends, dorsal epiblast cells display divi ...

Meeting Report – The 2019 FEBS special meeting on sphingolipid biology: sphingolipids in physiology and pathology

Giovanni D'Angelo

Sphingolipids are a fundamental class of molecules that are involved in structural, organizational and signaling properties of eukaryotic membranes. Defects in their production or disposal lead to acquired and inherited human diseases. A growing community ...

Imaging Lipid Metabolism at the Golgi Complex

The development of fluorescence-based molecular imaging has revolutionized cell biology allowing the visualization of specific biomolecules at the microscopic and, more recently, at the nanoscopic scale while in their relevant biological contexts. Nonethel ...

Visualizing sphingolipid biosynthesis in cells

Biosynthetic pathways play a fundamental role in the building and operation of the cell by synthesizing the constituents by which the cell is constructed, and by producing signalling intermediates that play a key role in cell regulation. While a lot is kno ...

Glycosphingolipid metabolism in cell fate specification

Giovanni D'Angelo, Laura Capolupo, Jaipreet Singh Loomba

Glycosphingolipids (GSLs) are ubiquitous components of eukaryotic plasma membranes that consist of a ceramide backbone linked to a glycan moiety. Both the ceramide and the glycan parts of GSLs display structural variations that result in a remarkable reper ...

2018

Photoactivation ('uncaging') is a powerful approach for releasing bioactive small molecules in living cells. Current uncaging methods are limited by the random distribution of caged molecules within cells. We have developed a mitochondria-specific photoact ...

Glycosphingolipid metabolic reprogramming drives neural differentiation

Giovanni D'Angelo, Riccardo Rizzo

Neural development is accomplished by differentiation events leading to metabolic reprogramming. Glycosphingolipid metabolism is reprogrammed during neural development with a switch from globo- to ganglio-series glycosphingolipid production. Failure to exe ...

A Click Cage: Organelle‐Specific Uncaging of Lipid Messengers

Lipid messengers exert their function on short time scales at distinct subcellular locations, yet most experimental approaches for perturbing their levels trigger cell-wide concentration changes. Herein, we report on a coumarin-based photocaging group that ...

2018

By combining dynamic light scattering (DLS) measurements and infrared (IR) spectroscopy with the interface- and bond-specificity of vibrational sum frequency generation scattering (SFS) spectroscopy, we probe several structural aspects of how zwitterionic ...

Sphingolipid metabolic flow controls phosphoinositide turnover at the trans ‐Golgi network

Giovanni D'Angelo, Howard Riezman, Riccardo Rizzo

Sphingolipids are membrane lipids globally required for eukaryotic life. The sphingolipid content varies among endomembranes with pre- and post-Golgi compartments being poor and rich in sphingolipids, respectively. Due to this different sphingolipid conten ...
