Elastic membrane heterogeneity of living cells revealed by stiff nanoscale membrane domains

Giovanni Dietler, Françoise Gisou van der Goot Grunberg, Paolo De Los Rios, Sandor Kasas, Charles Roduit, Pascal Steiner, Alexandre Yersin

Many approaches have been developed to characterize the heterogeneity of membranes in living cells. In this study, the elastic properties of specific membrane domains in living cells are characterized by atomic force microscopy. Our data reveal the existen ...

Infrared scanning near-field optical microscopy investigates order and clusters in model membranes

Giorgio Margaritondo, Johanna Generosi

Due to its surface sensitivity and high spatial resolution, scanning near-field optical microscopy (SNOM) has a significant potential to study the lateral organization of membrane domains and clusters. Compared to other techniques, infrared near-field micr ...

Palmitoylation of membrane proteins (Review)

Françoise Gisou van der Goot Grunberg

S-Palmitoylation is a reversible post-translational modification that results in the addition of a C16-carbon saturated fatty acyl chain to cytoplasmic cysteine residues. This modification is mediated by Palmitoyl-acyl Transferases that are starting to be ...

Limited diffusive fluxes of substrate facilitate coexistence of two competing bacterial strains

Dani Or

Soils are known to support a great bacterial diversity down to the millimeter scale, but the mechanisms by which such a large diversity is sustained are largely unknown. A feature of unsaturated soils is that water usually forms thin, poorly-connected film ...

Transition from Nanodomains to Microdomains Induced by Exposure of Lipid Monolayers to Air

Dusan Vobornik

The morphology of monolayers prepared from ternary lipid mixtures that have coexisting fluid phases has been examined by atomic force microscopy for samples transferred to mica before and after exposure to air. Mixtures of 1,2-dioleoyl- sn-glycero-3-phosph ...

Evaluation of AllnN/GaN HEMTs on sapphire substrate in microwave, time and temperature domains

Nicolas Grandjean, Jean-François Carlin, Eric Feltin, Marcel Py, Marcus Gonschorek

AllnN/GaN high electron mobility transistors (HEMTs) on sapphire substrate have yielded a maximum drain current density of 1.26 A/mm with a current gain cutoff and maximum oscillation frequencies about 26 and 40 GHz, respectively, for a 0.25 mu m gate leng ...

Diversity of raft-like domains in late endosomes

Françoise Gisou van der Goot Grunberg

BACKGROUND: Late endosomes, the last sorting station in the endocytic pathway before lysosomes, are pleiomorphic organelles composed of tubular elements as well as vesicular regions with a characteristic multivesicular appearance, which play a crucial role ...

Mean-field theory revives in self-oscillatory fields with non-local coupling

A simple mean-field idea is applicable to the pattern dynamics of large assemblies of limit-cycle oscillators with non-local coupling. This is demonstrated by developing a mathematical theory for the following two specific examples of pattern dynamics. Fir ...

Crystal Structure of the PP2A Phosphatase Activator: Implications for Its PP2A-Specific PPIase Activity

PTPA, an essential and specific activator of protein phosphatase 2A (PP2A), functions as a peptidyl prolyl isomerase (PPIase). We present here the crystal structures of human PTPA and of the two yeast orthologs (Ypa1 and Ypa2), revealing an all α-helical p ...

Oiling the wheels of the endocytic pathway

Françoise Gisou van der Goot Grunberg

An ever more complete picture of the organization and function of the endocytic pathway is emerging. New mechanisms, and in particular lipid- based mechanisms that couple membrane dynamics and sorting, are being unraveled. But the final picture is still co ...
