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...

Excited to share that our paper is out in @natcomms.nature.com

We uncover how MICAL1 regulates actin dynamics to enhance VWF–GPIbα binding in platelets.

Big thanks to all co-authors & collaborators !

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...

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

🚨BREAKING. From a program officer at the National Science Foundation, a list of keywords that can cause a grant to be pulled. I will be sharing screenshots of these keywords along with a decision tree. Please share widely. This is a crisis for academic freedom & science.
