Line Mathilde Brostrup Hansen talks about effects of age and sex on stroke outcomes in a mouse model (slight change from poster). After ischemia-reperfusion, older mice did worse - and sex needs to be taken into account. #CTH2024

Hot Topic Poster presentation by Jacqueline Condrau on endothelial injury: microglia enwrap the injured capillary but this is not necessary for capillary repair. Neither were pericytes and astrocytes🤯. Answer? Neighbouring endothelial cell extensions.

Great talk by Yamei Tang on radiation-induced brain injury. Pericytes are extremely sensitive to radiation: Reduced pericyte coverage, signs of mural cell damage. Thalidomide treatment salvaged pericytes, capillaries, BBB integrity, neuronal function in mice🤩 Enormous translational potential!

🛰️Andreas Mogensen visited @aarhusuni.bsky.social last night to share stories about his ISS missions… and how he slept. He was the first volunteer for the Center for Ear EEG's project to monitor sleep in astronauts!😴👂He returned his EEG earpiece and even had a gift for center leader Preben Kidmose. 🚀
