New Cell publication! A joint effort between @psich.bsky.social and collaborators reveals how microtubules act as spatiotemporal signal sensors regulating signaling proteins. Mechanistic immune insights from the Zippelius Lab @biomedizin.unibas.ch. 👏 www.sciencedirect.com/science/arti...

Without signal transmission via the cytoskeleton, cells could not divide or mount immune responses. Researchers at PSI and the University of Basel @biomedizin.unibas.ch have now shown how microtubules pass on such signals at the molecular level.

Since its launch 30 years ago, the STIP programme at PSI has become a globally unique and indispensable resource for understanding radiation damage in materials, helping to ensure the safe operation of nuclear facilities. Full story 👇
