Inactivation mechanisms of influenza A virus under pH conditions encountered in aerosol particles as revealed by whole-virus HDX-MS

Tamar Kohn, Jonathan Paz Montoya, Aline Laetitia Schaub, Athanasios Nenes, Giovanni D'Angelo, Kalliopi Violaki, Shannon Christa David, Ghislain Gilles Jean-Michel Motos, Walter Hugentobler

Multiple respiratory viruses, including influenza A virus (IAV), can be transmitted via expiratory aerosol particles, and aerosol pH was recently identified as a major factor influencing airborne virus infectivity. Indoors, small exhaled aerosols undergo r ...

The lipotype hypothesis

Giovanni D'Angelo, Gioele La Manno

Giovanni D'Angelo and Gioele La Manno present the concept of lipotypes, and suggest that lipid composition is an important regulator of cell fate. ...

CERT1 mutations perturb human development by disrupting sphingolipid homeostasis

Paolo De Los Rios, Bruno Lemaitre, Evelyne Ruchti, Sylvia Ho, Anthony Vocat, Samuel Rommelaere, Greta Limoni, Stefano Zamuner, Giovanni D'Angelo, Laura Capolupo, Charlotte Julie Caroline Gehin, Huixin Guo

Neural differentiation, synaptic transmission, and action potential propagation depend on membrane sphingolipids, whose metabolism is tightly regulated. Mutations in the ceramide transporter CERT (CERT1), which is involved in sphingolipid biosynthesis, are ...

Sphingolipids control dermal fibroblast heterogeneity

Olivier Burri, Sylvia Ho, Romain Guiet, Galina Glousker, Giovanni D'Angelo, Laura Capolupo, Gioele La Manno, Alex Russell Lederer, Irina Khven

Human cells produce thousands of lipids that change during cell differentiation and can vary across individual cells of the same type. However, we are only starting to characterize the function of these cell-to-cell differences in lipid composition. Here, ...

ER-Golgi-localized proteins TMED2 and TMED10 control the formation of plasma membrane lipid nanodomains

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Oksana Andrei Sergeeva, Audrey Geneviève Chuat, Muhammad Umair Anwar, Giovanni D'Angelo, Laura Capolupo, Francisco De Magalhães Sarmento R De Mesquita, Triana Amen

To promote infections, pathogens exploit host cell machineries such as structural elements of the plasma membrane. Studying these interactions and identifying molecular players are ideal for gaining insights into the fundamental biology of the host cell. H ...

Golgi maturation-dependent glycoenzyme recycling controls glycosphingolipid biosynthesis and cell growth via GOLPH3

Anthony Vocat, Giovanni D'Angelo, Laura Capolupo, Riccardo Rizzo

Glycosphingolipids are important components of the plasma membrane where they modulate the activities of membrane proteins including signalling receptors. Glycosphingolipid synthesis relies on competing reactions catalysed by Golgi-resident enzymes during ...

S-acylation controls SARS-CoV-2 membrane lipid organization and enhances infectivity

Béatrice Kunz, Didier Trono, Priscilla Turelli, Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Matteo Dal Peraro, Charlène Mireille Raymonde Raclot, Luciano Andres Abriata, Oksana Andrei Sergeeva, Giovanni D'Angelo, Francisco De Magalhães Sarmento R De Mesquita

SARS-CoV-2 virions are surrounded by a lipid bilayer that contains membrane proteins such as spike, responsible for target-cell binding and virus fusion. We found that during SARS-CoV-2 infection, spike becomes lipid modified, through the sequential action ...

GRASP55 regulates intra-Golgi localization of glycosylation enzymes to control glycosphingolipid biosynthesis

Giovanni D'Angelo, Laura Capolupo, Charlotte Julie Caroline Gehin, Riccardo Rizzo

The Golgi apparatus, the main glycosylation station of the cell, consists of a stack of discontinuous cisternae. Glycosylation enzymes are usually concentrated in one or two specific cisternae along the cis-trans axis of the organelle. How such compartment ...

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 ...
