Calcium-Mediated Liposome Fusion to Engineer Giant Lipid Vesicles with Cytosolic Proteins and Reconstituted Mammalian Proteins

Giant unilamellar lipid vesicles (GUVs) are widely used as model membrane systems and provide an excellent basis to construct artificial cells. To construct more sophisticated artificial cells, proteins-in particular membrane proteins-need to be incorporat ...

Structures of three MORN repeat proteins and a re-evaluation of the proposed lipid-binding properties of MORN repeats

Charlotte Julie Caroline Gehin

MORN (Membrane Occupation and Recognition Nexus) repeat proteins have a wide taxonomic distribution, being found in both prokaryotes and eukaryotes. Despite this ubiquity, they remain poorly characterised at both a structural and a functional level compare ...

Single-molecule kinetics of pore assembly by the membrane attack complex

Georg Fantner, Adrian Pascal Nievergelt

The membrane attack complex (MAC) is a hetero-oligomeric protein assembly that kills pathogens by perforating their cell envelopes. The MAC is formed by sequential assembly of soluble complement proteins C5b, C6, C7, C8 and C9, but little is known about th ...

Intracellular Recording of Cardiomyocyte Action Potentials with Nanopatterned Volcano-Shaped Microelectrode Arrays

Philippe Renaud, Arnaud Bertsch, Benoît Xavier Emmanuel Desbiolles

Micronanotechnology-based multielectrode ar- rays have led to remarkable progress in the field of transmembrane voltage recording of excitable cells. However, providing long-term optoporation- or electroporation-free intracellular access remains a consider ...

Nanoscale extracellular vesicles (EVs) including exosomes (50–150 nm membrane particles) have emerged as promising cancer biomarkers due to the carried genetic information about the parental cells. However the sensitive detection of these vesicles remains ...

Clustering on Membranes: Fluctuations and More

Julian Charles Shillcock

Clustering of extracellular ligands and proteins on the plasma membrane is required to perform specific cellular functions, such as signaling and endocy- tosis. Attractive forces that originate in perturbations of the membrane’s phys- ical properties contr ...

Background: Global warming has triggered an increase in the prevalence and severity of coral disease, yet little is known about coral/pathogen interactions in the early stages of infection. The point of entry of the pathogen and the route that they take on ...

Lipid exchange and signaling at ER–Golgi contact sites

Meticulous observations of the cell perinuclear region where the Golgi and the endoplasmic reticulum (ER) networks intermingle have revealed close contact sites of barely 20 nm between these two organelles. Recent studies demonstrate that molecular machine ...

Generation of Native, Untagged Huntingtin Exon1 Monomer and Fibrils Using a SUMO Fusion Strategy

Hilal Lashuel, Jonathan Jean-Pierre Ricci, Anass Chiki, Andreas Reif

Huntington’s Disease (HD) is an inherited fatal neurodegenerative disease caused by a CAG expansion (36) in the first exon of the HD gene, resulting in the expression of the Huntingtin protein (Htt) or N-terminal fragments thereof with an expanded polygl ...

pH sensing by lipids in membranes: The fundamentals of pH-driven migration, polarization and deformations of lipid bilayer assemblies

Anne-Florence Raphaëlle Bitbol

Most biological molecules contain acido-basic groups that modulate their structure and interactions. A consequence is that pH gradients, local heterogeneities and dynamic variations are used by cells and organisms to drive or regulate specific biological f ...
