A special day: Jean Solarz, my first PhD student, successfully defended his thesis. Proud of all the work accomplished! Thks to jury members.
We have worked for 2 years with @dianvanderwaldr.bsky.social to propose a protocol for platelet desialylation, and we are excited to now share it. Communication from the ISTH SSC Platelet Physiology. - Journal of Thrombosis and Haemostasis www.jthjournal.org/article/S153... #hemsky #hemesky
Bravo Jean Solarz for your presentation at the French Society of Hematology on MICAL1 @hithlabinserm1176.bsky.social #sfh #Hemsky #hemesky
Incredible trail ! 45 km, 2000 D+/2600 D- #utgc Ultra Trail du Grand Colombier, Ain

Excited to share that our paper is out in @natcomms.nature.com 🔗 rdcu.be/ez3Gt We uncover how MICAL1 regulates actin dynamics to enhance VWF–GPIbα binding in platelets. Big thanks to all co-authors & collaborators ! @hithlabinserm1176.bsky.social @echardlab-pasteur.bsky.social

Plenary session at the SFH with Prof. Marie-Christine Alessi invited for a talk on phenotype/genotype in platelet disorders with Hana Raslova as moderator. #hemesky #hemsky #sfh
F-actin disassembly by the oxidoreductase MICAL1 promotes mechano-dependent VWF-GPIbα interaction in platelets
Nature Communications - To stop bleeding from an injured vessel, platelets adhere and form a clot despite high shear stress from the flow. Here, the authors show that platelet actin disassembly is...

Consensus protocol for platelet desialylation (β-galactose exposure) quantification using lectins by flow cytometry: Communication from the ISTH SSC Subcommittee on Platelet Physiology.
Platelets contain many heterogeneous carbohydrates (glycans): often capped by sialic acid. The removal of sialic acid (desialylation) is important for platelet function and clearance, leading to novel...
