Interactions between pili affect the outcome of bacterial competition driven by the type VI secretion system
Melanie Blokesch, Anne-Florence Raphaëlle Bitbol, Alexandre Lemopoulos, Richard Marie Servajean, Simon Bernhard Otto
The bacterial type VI secretion system (T6SS) is a widespread, kin-discriminatory weapon capable of shaping microbial communities. Due to the system’s dependency on contact, cellular interactions can lead to either competition or kin protection. Cell-to-ce ...
2024The CRL5-SPSB3 ubiquitin ligase targets nuclear cGAS for degradation
Andrea Ablasser, Baptiste Claude André Guey, Jonathan Jean-Pierre Ricci, Chong Liu, Pauline Ambre Melenec, Pengbiao Xu, Lingyun Li, Ying Liu
Cyclic GMP-AMP synthase (cGAS) senses aberrant DNA during infection, cancer and inflammatory disease, and initiates potent innate immune responses through the synthesis of 2 ' 3 '-cyclic GMP-AMP (cGAMP)1-7. The indiscriminate activity of cGAS towards DNA d ...
Nature Portfolio2024Homogeneous vs. heterogeneous photo-Fenton elimination of antibiotic-resistant bacteria bearing intracellular or extracellular resistance: Do resistance mechanisms interfere with disinfection pathways?
César Pulgarin, Stefanos Giannakis, Truong-Thien Melvin Le, Jérémie Decker
The present study aimed to fill the knowledge gap between the implications of intracellular and extracellular antibiotic resistance mechanisms may inflict on the inactivation pathways of the photo-Fenton process under mild conditions. It was thus designed ...
London2024High energy-density electrostatic actuators for soft robotics
This thesis reports high energy-density electrostatic actuators for use in soft robotics. This thesis has two main parts: a) a detailed study of electro-adhesion using microfabricated electrodes, and b) a flexi-ble fiber-shaped linear motor.Electro-adhesio ...
EPFL2024Microfluidic device combining hydrodynamic and dielectrophoretic trapping for the controlled contact between single micro-sized objects and application to adhesion assays
Philippe Renaud, Arnaud Bertsch, Clémentine Sophie Sarah Lipp
The understanding of cell-cell and cell-matrix interactions via receptor and ligand binding relies on our ability to study the very first events of their contact. Of particular interest is the interaction between a T cell receptor and its cognate peptide-m ...
ROYAL SOC CHEMISTRY2023Observed Kinetics of Enterovirus Inactivation by Free Chlorine Are Host Cell-Dependent
Tamar Kohn, Shannon Christa David, Shotaro Torii, Federica Cariti
Virucidal efficacies of disinfectants are typically assessed by infectivity assay utilizing a single type of host cell. Enteroviruses infect multiple host cells via various entry routes, and each entry route may be impaired differently by a given disinfect ...
2023Biofilm morphogenesis on soft hydrogels
Bacteria often colonize their environment in the form of surface attached multicellular communities called biofilms. Biofilms grow from surface-attached cells that undergo division while self-embedding in a viscoelastic matrix. Biofilms grow at the surface ...
EPFL2023Neurogenesis redirects β-catenin from adherens junctions to the nucleus to promote axonal growth
Here, we show that, in the developing spinal cord, after the early Wnt-mediated Tcf transcription activation that confers dorsal identity to neural stem cells, neurogenesis redirects beta-catenin from the adherens junctions to the nucleus to stimulate Tcfo ...
Cambridge2023Protocol for live imaging of intracellular nanoscale structures using atomic force microscopy with nanoneedle probes
Atomic force microscopy (AFM) is capable of nanoscale imaging but has so far only been used on cell surfaces when applied to a living cell. Here, we describe a step-by-step protocol for nanoendoscopy-AFM, which enables the imaging of nanoscale structures i ...
2023In situ quantification of osmotic pressure within living embryonic tissues
Sangwoo Kim, Antoine Claude Jean Vian
Mechanics is known to play a fundamental role in many cellular and developmental processes. Beyond active forces and material properties, osmotic pressure is believed to control essential cell and tissue characteristics. However, it remains very challengin ...
