Axons in the Hills was a great 2-day meeting about all things axons was organized by Maren Engelhardt, Maarten Kole, Andreas Draguhn and Paul Jenkins at the Heidelberg University. Christophe chaired the “Molecular Organization of Axons” featuring Marseille colleague Dominique Debanne, Juan Garrido and Elisa d’Este. Fun experience and great science!
Christophe was interviewed by journalist Anne Debroise of the French scientific magazine Science & Vie about a recent article from the Bock lab (Zheng et al., 2018) that provides the volume of an adult Drosophila fly brain by electron microscopy. You can read the short article here (in French, subscription required) or via the screenshot below.
We all said goodbye to Nikki who finished her Master’s internship at the end of July. Nikki is a great student, and she managed to get a PhD position in the lab of Ruud Toonen at the Center for Neurogenomics and Cognitive Research in Amsterdam. Good luck for this new adventure!
Christophe was in Nantes to talk at the first biennale of the Nikon Center of Excellence Nantes (CENN), devoted to “Super-resolution microscopy for Biology”. Diverse and interesting talks from Stefan Balint, James Zheng, Anne Beghin et al. in the beautiful Musée des Beaux-Arts of Nantes.
Christophe was lucky to share the stage with Ryohei Yasuda, Marina Mikhaylova and Sonja Hofer for a symposium dedicated to neuronal imaging. Thanks to Deepak Srivastava for the invite (the fish n’ chips was delicious)!
We had the chance of having Dominic Bingham, currently a Master’s student in Alison Twelvetree’s lab in Sheffield, apply for a PhD in the lab through the “Integrative and Clinical Neuroscience” PhD program. Congratulation to Dominic who succeeded to be one of the three laureates this year! We can’t wait to have him the lab where he will study the organization of presynaptic actin. Thanks also to the Aix-Marseille University A*MIDEX which is funding the PhD program.
It was a pleasure to present at the 7th Cell Adhesion Club Meeting in Strasbourg. After three fascinating days hearing about cell adhesion and related cell biological processes by top scientists of the field, it was very interesting to see how key tools and concepts can also inform cellular neurobiology. See the #Stradh18 Twitter hashtag for more, thanks to @GoetzJacky for the invite!
Marie-Jeanne and Christophe wrote a review detailing how recent discoveries renewed the understanding of axonal actin organization. In the axon shaft itself, new nano-structures such as rings, hotspots and trails have been described, but their function remains to be elucidated. At presynapses, the precise architecture of actin is still elusive, and contradicting findings have been reported regarding its function. This is an exciting time to study actin in axons!
The review is now published in Molecular and Cellular Neuroscience, and will be part of a special issue on “Membrane Trafficking and Cytoskeletal Dynamics in Neuronal Function”. If you don’t have access to the review, a preprint manuscript is available on Zenodo.
