Dynamic Micropatterning Reveals Spatial Dynamics of B Cell Receptor Signaling and Immune Synapse Formation
B cell activation by foreign antigens, recognized by the B cell receptor (BCR), is the key prerequisite for cell differentiation for antibody production. B cells typically encounter antigens bound to ...

Great to see this out! Awesome work, @yusefflab.bsky.social, and thank you for the collaboration!
Aceitón, Riobó, Del Valle Batalla, Yuseff et al show that B cells respond to mechanical cues at the immune synapse through ATAT1-dependent microtubule acetylation to coordinate cytoskeletal dynamics & lysosome positioning, enhancing antigen extraction and presentation rupress.org/jcb/article/...

Pinja had a great visit in Munich to learn all the little tricks about purification of yellow fever 17D viral vaccine (so that we can next stick it into B cells to see how they deal with it). Thanks so much Anne and Margarita for kindly hosting Pinja!
🔬Dr. Pinja Jalkanen (Turku) visited Prof. Anne Krug’s (@kruglab.bsky.social) lab (LMU Munich), hosted by Margarita Shnipova, for hands-on training in YF17D virus purification. This exchange boosts collaboration and supports WP1 research on immune response.🤝🧬
