Endogenous Regulators of Gamma-Secretase and Amyloid-Beta Production, and Engineering of Alzheimer's Disease Therapeutic Tools

Sébastien Mosser

Alzheimer s disease (AD) is a devastating neurodegenerative disease characterized by strong cognitive impairment and memory loss. These symptoms are caused by neuronal death, induced by two pathological hallmarks: extracellular senile plaques composed of a ...

Experimental Validation of a Filament Transport Model in Turbulent Magnetized Plasmas

Nicola Vianello

In a wide variety of natural and laboratory magnetized plasmas, filaments appear as a result of interchange instability. These convective structures substantially enhance transport in the direction perpendicular to the magnetic field. According to filament ...

Improving the quality of filament-impaired images in Kerr media by statistical averaging

Demetri Psaltis, Alexandre Goy

In focusing Kerr media, small- scale filamentation is the major obstacle to imaging at high light intensities. In this article, we experimentally and numerically demonstrate a method based on statistical averaging to reduce the detrimental effects of filam ...

High-Resolution Correlative Microscopy: Bridging the Gap between Single Molecule Localization Microscopy and Atomic Force Microscopy

Aleksandra Radenovic, Georg Fantner, Adrian Pascal Nievergelt, Hendrik Georges Deschout, Lely Feletti, Radek Jankele, Pascal Damian Odermatt, Arun Shivanandan

Nanoscale characterization of living samples has become essential for modern biology. Atomic force microscopy (AFM) creates topological images of fragile biological structures from biomolecules to living cells in aqueous environments. However, correlating ...

A formin-nucleated actin aster concentrates cell wall hydrolases for cell fusion in fission yeast

Arne Seitz, Thierry Laroche, Omaya Pierre Dudin

Cell-cell fusion is essential for fertilization. For fusion of walled cells, the cell wall must be degraded at a precise location but maintained in surrounding regions to protect against lysis. In fission yeast cells, the formin Fus1, which nucleates linea ...

Mechanical properties of peripheral stress fibers in adherent cells spreading on patterned substrates

Céline Jeanne Labouesse

Many cellular processes require or depend on mechanical feedback from the cell's micro-environment. For example, the local organization of the actin cytoskeleton is known to adapt to the physical properties of the extracellular matrix. To gain better under ...

Hubble Frontier Fields: the geometry and dynamics of the massive galaxy cluster merger MACSJ0416.1-2403

Jean-Paul Richard Kneib, Hakim Atek, Benjamin Yvan Alexandre Clement, David Richard Harvey, Markus Rexroth

We use a joint optical/X-ray analysis to constrain the geometry and history of the ongoing merging event in the massive galaxy cluster MACSJ0416.1-2403 (z = 0.397). Our investigation of cluster substructure rests primarily on a combined strong-and weak-len ...

Ultra-soft cantilevers and 3-D micro-patterned substrates for contractile bundle tension measurement in living cells

Jean-Jacques Meister, Alexander Verkhovskiy, Chiara Gabella, Benoît Vianay, Niccolo Piacentini

Actin-myosin microfilament bundles or stress-fibers are the principal tension-generating structures in the cell. Their mechanical properties are critical for cell shape, motion, and interaction with other cells and extracellular matrix, but were so far dif ...
