@tomasz.grzywa: Did you know a single immune cell can repair a brain vessel? 🧠🩸 We’ve looked at immune cells fighting cancer and chasing pathogens in my previous reels… but their abilities go far beyond that. Here’s one of their most unexpected jobs: repairing a broken blood vessel in the brain. In this real-time zebrafish video, a single macrophage (in green!) rushes to a ruptured brain blood vessel - the kind of break that can cause hemorrhagic stroke or microbleeds - and literally grabs both loose ends and pulls them back together. Using high-resolution live imaging and a laser-induced rupture model, researchers discovered that macrophages don’t just clean up damage. They physically fix it! They extend filopodia and lamellipodia, adhere to each broken end, and generate traction forces that help the vessel reseal. This reveals a completely new role for macrophages in maintaining brain vascular integrity and can open doors to new stroke therapies.
