Insertion of Nanoparticle Clusters into Vesicle Bilayers

Rudolf Hovius, Davide Demurtas, Alke Fink

A major contemporary concern in developing eective liposomeÀnanoparticle hybrids is the present inclusion size limitation of nanoparticles between vesicle bilayers, which is considered to be around 6.5 nm in diameter. In this article, we present experimen ...

Membrane vesicles as a novel strategy for shedding encrusted cell surfaces

Rizlan Bernier-Latmani, Paul Pao-Yun Shao

Surface encrustation by minerals, which impedes cellular metabolism, is a potential hazard for microbes. The reduction of U(VI) to U(IV) by Shewanella oneidensis strain MR-1 leads to the precipitation of the mineral uraninite, as well as a non-crystalline ...

Refining Mitochondria Segmentation in Electron Microscopy Imagery with Active Surfaces

Pascal Fua, Anne Alison Jorstad

We present an active surface-based method for refining the boundary surfaces of mitochondria segmentation data. We exploit the fact that mitochondria have thick dark membranes, so referencing the image data at the inner membrane can help drive a more accur ...

Structure-Based Engineering of a Minimal Porin Reveals Loop-Independent Channel Closure

Hans Wolfgang Grosse

Porins, like outer membrane protein G (OmpG) of Escherichia coli, are ideal templates among ion channels for protein and chemical engineering because of their robustness and simple architecture. OmpG shows fast transitions between open and closed states, w ...

Endosomes: Guardians Against [Ru(Phen)3]2+ Photo-action In Endothelial Cells During In Vivo pO2 Detection?

Georges Wagnières, Veronika Huntosova

Phototoxicity is a side-effect of in vitro and in vivo oxygen partial pressure (pO(2)) detection by luminescence lifetime measurement methods. Dichlorotris(1,10-phenanthroline)-ruthenium(II) hydrate (Ru(Phen)(3)) is a water soluble pO(2) probe associ ...

On-chip light sheet illumination enables diagnostic size and concentration measurements of membrane vesicles in biofluids

Philippe Renaud, Sébastien Jiguet, Hendrik Georges Deschout, Pietro Maoddi

Cell-derived membrane vesicles that are released in biofluids, like blood or saliva, are emerging as potential non-invasive biomarkers for diseases, such as cancer. Techniques capable of measuring the size and concentration of membrane vesicles directly in ...

Exploiting Enclosing Membranes and Contextual Cues for Mitochondria Segmentation

Pascal Fua, Aurélien Lucchi, Carlos Joaquin Becker, Pablo Marquez Neila

In this paper, we improve upon earlier approaches to segmenting mitochondria in Electron Microscopy images by explicitly modeling the double membrane that encloses mitochondria, as well as using features that capture context over an extended neighborhood. ...

Molecular and Dimensional Profiling of Highly Purified Extracellular Vesicles by Fluorescence Fluctuation Spectroscopy

Horst Vogel, Davide Demurtas, Luigino Grasso, Romain Wyss, Camille Wolf, Hans Wolfgang Grosse

Cells secrete extracellular vesicles (EVs) into their microenvironment that act as mediators of intercellulard communication under physiological conditions and in this context also actively participate in spreading various diseases. Large efforts are curre ...

How Viruses Hijack the ERAD Tuning Machinery

Maurizio Molinari, Riccardo Bernasconi

An essential step during the intracellular life cycle of many positive-strand RNA viruses is the rearrangement of host cell membranes to generate membrane-bound replication platforms. For example, Nidovirales and Flaviviridae subvert the membrane of the en ...

Contact Angle at the Leading Edge Controls Cell Protrusion Rate

László Forró, Jean-Jacques Meister, Niccolo Piacentini, Chiara Gabella, Sylvia Jeney, Elena Bertseva, Alicia Carine Bornert

Plasma membrane tension and the pressure generated by actin polymerization are two antagonistic forces believed to define the protrusion rate at the leading edge of migrating cells [1-5]. Quantitatively, resistance to actin protrusion is a product of membr ...
