Endocytosis of the anthrax toxin is mediated by clathrin, actin and unconventional adaptors

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Béatrice Kunz, Mirko Bischofberger, Romain Fernand Pietro Groux

The anthrax toxin is a tripartite toxin, where the two enzymatic subunits require the third subunit, the protective antigen (PA), to interact with cells and be escorted to their cytoplasmic targets. PA binds to cells via one of two receptors, TEM8 and CMG2 ...

Retrieval of a Metabolite from Cells with Polyelectrolyte Microcapsules

Mathias Winterhalter, Deborah Studer

To monitor cellular processes in individual cells, it is important to measure the concentrations of intracellular metabolites and to retrieve them for analysis. The use of functionalized polyelectrolyte microcapsules as intracellular sensors for in vivo re ...

Anthrax toxin triggers the activation of src-like kinases to mediate its own uptake

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Béatrice Kunz

AB-type toxins, like other bacterial toxins, are notably opportunistic molecules. They rely on target cell receptors to reach the appropriate location within the target cell where translocation of their enzymatic subunits occurs. The anthrax toxin, however ...

Hybrid Polymer Therapeutics Incorporating Bioresponsive, Coiled Coil Peptide Linkers

Nanopharmaceuticals or nanomedicines are defined as nanometer sized (1 to 1000 nm) complex systems, consisting of at least two components, one of which being the biologically active moiety such as a drug, peptide, protein or nucleotide. Several nano-sized ...

Valproic acid enhances recombinant mRNA and protein levels in transiently transfected Chinese hamster ovary cells

Florian Maria Wurm, David Hacker, Lucia Baldi Unser, Sarah Wulhfard

Valproic acid (VPA) is a small molecule that inhibits histone deacetylase activity. Here we report that VPA increases recombinant mRNA and protein levels in transiently transfected CHO DG44 cells. In the presence of VPA, transient recombinant antibody yiel ...

GTPase Activity Plays a Key Role in the Pathobiology of LRRK2

Darren Moore

Mutations in the leucine-rich repeat kinase 2 (LRRK2) gene are associated with late-onset, autosomal-dominant, familial Parkinson's disease (PD) and also contribute to sporadic disease. The LRRK2 gene encodes a large protein with multiple domains, includin ...

Membrane nanotubes drawn by optical tweezers transmit electrical signals between mammalian cells over long distances

Horst Vogel, Marinela Gjoni Boillat, Pedro Pascoal, Davor Kosanic

Biological cells continuously change shape allowing essential functions such as cell motility, vesicle-mediated release/uptake of soluble and membrane components or nanotube-mediated cell–cell communications. Here we use single cell micromanipulation to in ...

Multicolor Bleach-Rate Imaging Enlightens in vivo Sterol Transport

Daniel Sage

Elucidation of in vivo cholesterol transport and its aberrations in cardiovascular diseases requires suitable model organisms and the development of appropriate monitoring technology. We recently presented a new approach to visualize transport of the intri ...

Riding shotgun: a dual role for the epidermal growth factor-Cripto/FRL-1/Cryptic protein Cripto in Nodal trafficking

Daniel Constam

Nodal is a secreted protein of the transforming growth factor beta (TGFbeta) family that activates Smad2 and Smad3 transcription factors through complexes of type I and type II activin receptors and glycosyl-phosphatidylinositol-anchored coreceptors of the ...

Calpain hydrolysis of alpha- and beta2-adaptins decreases clathrin-dependent endocytosis and may promote neurodegeneration

Harald Hirling, Nikita Rudinskiy

Clathrin-dependent endocytosis is mediated by a tightly regulated network of molecular interactions that provides essential protein-protein and protein-lipid binding activities. Here we report the hydrolysis of the alpha- and beta2-subunits of the tetramer ...
