Soil protist function varies with elevation in the Swiss Alps

Nicolas Jean Philippe Guex, Edward Mitchell, Enrique Lara, Aline Buri

Protists are abundant and play key trophic functions in soil. Documenting how their trophic contributions vary across large environmental gradients is essential to understand and predict how biogeochemical cycles will be impacted by global changes. Here, u ...

Dispositif et procédé pour l'évaluation de la contraction cellulaire

Boris Hinz, Pierre Jean Arnould Wipff

A method for assessing cell contraction includes adhering contractile cells to an oxidized and cellular adhesion activated surface of a biocompatible silicone elastomer film. The biocompatible silicone elastomer film allows the cells to contract and wrinkl ...

Use of VacA as a Vaccine Antigen

Dominique Velin, Mati André Marie Moyat

One of the major toxins secreted by H. pylori is the Vacuolating cytotoxin A (VacA) named after its ability to induce the formation of "vacuole"-like membrane vesicles in the cytoplasm of gastric cells. VacA has been associated with the disruption of mitoc ...

Nano Secondary Ion Mass Spectrometry Imaging of Dopamine Distribution Across Nanometer Vesicles

Anders Meibom, Anna Larsson

We report an approach to spatially resolve the content across nanometer neuroendocrine vesicles in nerve-like cells by correlating super high-resolution mass spectrometry imaging, NanoSIMS, with transmission electron microscopy (TEM). Furthermore, intracel ...

An intracellular replication niche for Vibrio cholerae in the amoeba Acanthamoeba castellanii

Melanie Blokesch, Catherine Maclachlan, Tiziana Scrignari, Charles Ulric V Van der Henst

Vibrio cholerae is a human pathogen and the causative agent of cholera. The persistence of this bacterium in aquatic environments is a key epidemiological concern, as cholera is transmitted through contaminated water. Predatory protists, such as amoebae, a ...

Impaired myogenesis in estrogen-related receptor γ (ERRγ)-deficient skeletal myocytes due to oxidative stress

Johan Auwerx

Specialized contractile function and increased mitochondrial number and oxidative capacity are hallmark features of myocyte differentiation. The estrogen-related receptors (ERRs) can regulate mitochondrial biogenesis or mitochondrial enzyme expression in s ...

A multichamber fluidic device for 3D cultures under interstitial flow with live imaging: Development, characterization, and applications

Melody Swartz, Jan Overney, James Brandon Dixon, Adrian Chung-Kai Shieh, Carmen Bonvin

Interstitial flow is an important biophysical cue that can affect capillary morphogenesis, tumor cell migration, and fibroblast remodeling of the extracellular matrix, among others. Current models that incorporate interstitial flow and that are suitable fo ...

Mechanical orchestration of tissue remodeling

Pierre Jean Arnould Wipff

After organ injury, a complex sequence of events is triggered to heal the tissue and to form a scar. Myofibroblasts, specialized contractile and secretory fibroblasts, are one of the many cell types that participate in the remodeling process. Myofibroblast ...
