Hey friends. I’m looking for a postdoc interested in studying host-pathogen interactions and immunology of tuberculosis. Send me some good people! We have a great group here! Email me [email protected]. Thanks!

IPBS researchers created LiveLung-TB, a BSL-3 imaging platform that visualizes real-time immune responses in Mtb-infected lungs. They found most CD4 T cells fail to reach infected cells, revealing physical barriers that limit TB immunity—a new window into host-pathogen dynamics! 🔬🫁 #Tuberculosis

Des chercheurs de l’IPBS (@chrisverollet.bsky.social et coll.) ont découvert que la protéine moésine régule les ostéoclastes, les cellules qui résorbent l’os. Sans elle, les os s’affaiblissent. Une piste prometteuse contre l’ #ostéoporose. 📘 @jcb.org shorturl.at/OhNSa

Too much cell fusion can break your bones, literally! IPBS researchers @chrisverollet.bsky.social & coll. found that moesin keeps bone-resorbing cells (osteoclasts) in check. Without it, bones weaken, a discovery that could inspire new #osteoporosis treatments. 📘 @jcb.org shorturl.at/N0Esc
