Cholesterol-Containing Liposomes Decorated With Au Nanoparticles as Minimal Tunable Fusion Machinery

Francesco Stellacci, Paulo Henrique Jacob Silva, Ester Canepa, Giulia Rossi

Membrane fusion is essential for the basal functionality of eukaryotic cells. In physiological conditions, fusion events are regulated by a wide range of specialized proteins, operating with finely tuned local lipid composition and ionic environment. Fusog ...

Antiviral Screen against Canine Distemper Virus-Induced Membrane Fusion Activity

Gerardo Turcatti, Marc Chambon, Jonathan Patrice Vesin

Canine distemper virus (CDV), a close relative of the human pathogen measles virus (MeV), is an enveloped, negative sense RNA virus that belongs to the genus Morbillivirus and causes severe diseases in dogs and other carnivores. Although the vaccination i ...

Targeting mitochondrial bioenergetics and NAD+ metabolism during sarcopenia and regeneration of skeletal muscle

Tanja Sonntag

The progressive decline of muscle mass and function called sarcopenia is a multi-factorial process associated to frailty, disability, and low quality of life in the elderly. The co-factor nicotinamide adenine dinucleotide (NAD+) becomes a limiting factor i ...

Efficient transdifferentiation of human dermal fibroblasts into skeletal muscle

Noaf Salah Ali Alwahab

Skeletal muscle holds significant regenerative potential but is incapable of restoring tissue loss caused by severe injury, congenital defects or tumour ablation. Consequently, skeletal muscle models are being developed to study human pathophysiology and r ...

Bioluminescent Antibodies for Point-of-Care Diagnostics

Kai Johnsson, Rudolf Griss, Alberto Schena, Qiuliyang Yu, Lin Xue

We introduce a general method to transform antibodies into ratiometric, bioluminescent sensor proteins for the no-wash quantification of analytes. Our approach is based on the genetic fusion of antibody fragments to NanoLuc luciferase and SNAP-tag, the lat ...

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

Thierry Laroche, Arne Seitz, Omaya Pierre Dudin, Raphaël Groux

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 ...

Research in the field of single biopolymers using scanning probe microscopy

Andrey Mikhaylov

Current thesis is devoted to the investigation of biopolymers using AFM, a well established and widely used technique. To begin with, we studied processing of AFM images and its automation. Our software product, DNA Trace, permit one to quickly extract sci ...

Force-induced globule-coil transition in laminin binding protein and its role for viral-cell membrane fusion

Giovanni Dietler, Fabrizio Benedetti, Andrey Mikhaylov, Tatyana Karakouz, Denis Korneev

The specific interactions of the pairs laminin binding protein (LBP)-purified tick-borne encephalitis viral surface protein E and certain recombinant fragments of this protein, as well as West Nile viral surface protein E and certain recombinant fragments ...

Effect of Particle Diameter and Surface Composition on the Spontaneous Fusion of Monolayer-Protected Gold Nanoparticles with Lipid Bilayers

Francesco Stellacci, Randy Patrick Carney, Ye Yang

Anionic, monolayer-protected gold nanoparticles (AuNPs) have been shown to nondisruptively penetrate cellular membranes. Here, we show that a critical first step in the penetration process is potentially the fusion of such AuNPs with lipid bilayers. Free e ...

Acetylcholine Receptor Organization in Membrane Domains in Muscle Cells: EVIDENCE FOR RAPSYN-INDEPENDENT AND RAPSYN-DEPENDENT MECHANISMS

Horst Vogel, Rudolf Hovius, Jean-Manuel Segura, Joachim Piguet, Christoph Schreiter

Nicotinic acetylcholine receptors (nAChR) in muscle fibers are densely packed in the postsynaptic region at the neuromuscular junction. Rapsyn plays a central role in directing and clustering nAChR during cellular differentiation and neuromuscular junction ...
