Role of Nimrod receptors in the Drosophila melanogaster cellular immune response

The use of modern molecular biology tools and simple but powerful tractable model organisms such as Drosophila has contributed significantly to our recent advances in the innate immunity field, notably phagocytosis. Since 2001, many phagocytic transmembran ...

Role of BMP Signaling for the Formation of Auditory Brainstem Nuclei and Large Auditory Relay Synapses

Ralf Schneggenburger, Christopher Clark, Elin Kristina Kronander

Large excitatory synapses are found at specific points in the neuronal circuits of the auditory brainstem, to enable fast information transfer and the preservation of acoustic timing information. The extracellular cues and signaling mechanisms that lead to ...

Mitochondrial activity detected by cantilever based sensor

Giovanni Dietler, Sandor Kasas, Petar Stupar, Wojciech Chomicki

Our team recently demonstrated that cantilever based devices can detect signature of life in a chemistry independent manner. In this technique, the organism of interest is attached onto a classical AFM cantilever. If alive, it induces nanometre scale oscil ...

Protrusion-retraction switches and traction forces in spontaneous cell polarization

Alicia Carine Bornert

Cell migration is a fundamental property of all animal cells which is involved in processes such as embryogenesis, immune response, tissue regeneration and cancer metastasis. Directional migration requires cell polarization which could happen in response t ...

Feeding behaviour of a benthic species (Ammonia tepida) under oxic and anoxic conditions: TEM-NanoSIMS correlation

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

More and more marine areas are subjected to depleted-O2 concentration, mainly due to eutrophication induced by human activities. These phenomena affect benthic ecosystems, in particular continental shelves and coastal areas where the renewal of the bottom ...

Fundamental Constraints on the Abundances of Chemotaxis Proteins

Anne-Florence Raphaëlle Bitbol

Flagellated bacteria, such as Escherichia coli, perform directed motion in gradients of concentration of attractants and repellents in a process called chemotaxis. The E. coli chemotaxis signaling pathway is a model for signal transduction, but it has uniq ...

Clostridium difficile toxin CDT hijacks microtubule organization and reroutes vesicle traffic to increase pathogen adherence

Henning Paul-Julius Stahlberg

Clostridium difficile causes antibiotic-associated diarrhea and pseudomembranous colitis by the actions of Rho-glucosylating toxins A and B. Recently identified hypervirulent strains, which are associated with increased morbidity and mortality, additionall ...

Ultra-soft cantilevers and 3-D micro-patterned substrates for contractile bundle tension measurement in living cells

Jean-Jacques Meister, Niccolo Piacentini, Chiara Gabella, Benoît Vianay

Actin-myosin microfilament bundles or stress-fibers are the principal tension-generating structures in the cell. Their mechanical properties are critical for cell shape, motion, and interaction with other cells and extracellular matrix, but were so far dif ...
