Ligand Binding to the Collagen VI Receptor Triggers a Talin-to-RhoA Switch that Regulates Receptor Endocytosis

Françoise Gisou van der Goot Grunberg, Matteo Dal Peraro, Laurence Gouzi Abrami, Luciano Andres Abriata, Béatrice Kunz, Shixu Yan

Capillary morphogenesis gene 2 (CMG2/ANTXR2) is a cell surface receptor for both collagen VI and anthrax toxin. Biallelic loss-of-function mutations in CMG2 lead to a severe condition, hyaline fibromatosis syndrome (HFS). We have here dissected a network o ...

Organelle-specific targeting of polymersomes into the cell nucleus

Zekiye Pelin Güven

Organelle-specific nanocarriers (NCs) are highly sought after for delivering therapeutic agents into the cell nucleus. This necessitates nucleocytoplasmic transport (NCT) to bypass nuclear pore complexes (NPCs). However, little is known as to how comparabl ...

A Molecular Logic Gate Enables Single-Molecule Imaging and Tracking of Lipids in Intracellular Domains

Pablo Rivera Fuentes, Adam Miklos Eördögh

Photoactivatable dyes enable single-molecule imaging and tracking in biology. Despite progress in the development of new fluorophores and labeling strategies, many intracellular compartments remain difficult to image beyond the limit of diffraction in livi ...

Mammalian membrane trafficking as seen through the lens of bacterial toxins

Françoise Gisou van der Goot Grunberg, Francisco De Magalhães Sarmento R De Mesquita, Oksana Andrei Sergeeva

A fundamental question of eukaryotic cell biology is how membrane organelles are organised and interact with each other. Cell biologists address these questions by characterising the structural features of membrane compartments and the mechanisms that coor ...

Cellular Uptake and Intracellular Trafficking of Poly(N-(2-Hydroxypropyl) Methacrylamide)

Anders Meibom, Harm-Anton Klok, Graham Knott, Stéphane Laurent Escrig, Olivier Burri, Arne Seitz, Claudia Battistella, Romain Guiet

Cellular uptake and intracellular trafficking of polymer conjugates or polymer nanoparticles is typically monitored using fluorescence-based techniques such as confocal microscopy. While these methods have provided a wealth of insight into the internalizat ...

Live imaging screen reveals that TYRO3 and GAK ensure accurate spindle positioning in human cells

Pierre Gönczy, Coralie Busso, Benita Wolf

Proper spindle positioning is crucial for spatial cell division control. Spindle positioning in human cells relies on a ternary complex comprising G alpha i1-3, LGN and NuMA, which anchors dynein at the cell cortex, thus enabling pulling forces to be exert ...

Drug-induced increase in lysobisphosphatidic acid reduces the cholesterol overload in Niemann-Pick type C cells and mice

Marc Moniatte, Jonathan Paz Montoya

Most cells acquire cholesterol by endocytosis of circulating low-density lipoproteins (LDLs). After cholesteryl ester de-esterification in endosomes, free cholesterol is redistributed to intracellular membranes via unclear mechanisms. Our previous work sug ...

Function, evolution, and structure of J-domain proteins

Paolo De Los Rios, Alessandro Barducci, Pierre Goloubinoff

Hsp70 chaperone systems are very versatile machines present in nearly all living organisms and in nearly all intracellular compartments. They function in many fundamental processes through their facilitation of protein (re)folding, trafficking, remodeling, ...

pH-Sensitive Coiled-Coil Peptide-Cross-Linked Hyaluronic Acid Nanogels: Synthesis and Targeted Intracellular Protein Delivery to CD44 Positive Cancer Cells

Harm-Anton Klok, Jian Zhang, Yu Jiang

The clinical translation of protein drugs that act intracellularly is limited by the absence of safe and efficient intracellular protein delivery vehicles. Here, pH-sensitive coiled-coil peptide-cross-linked hyaluronic acid nanogels (HA-cNGs) were designed ...
