Une méta-analyse de 100 études menées dans 36 pays montre que les citoyens préfèrent généralement les migrants qualifiés et maîtrisant la langue du pays d’accueil. Mais elle révèle aussi des attitudes envers l'immigration globalement plus positives que ne le suggère le débat public.

So inspiring to see the next generation of researchers in action. Their science gets clearer and more impactful every year. Watching Max Caouaille and Aizat Abdul at #TBVAC was genuinely moving. Great science, great storytelling, huge passion. The future of research is in very good hands. 👏
The Barber lab is looking to hire post-docs to work on #tuberculosis #immunology using murine and NHP models. BSL3 experience not required. Check out our lab in the NIH intramural program in Bethesda MD!
A great meeting ahead for host and pathogen aficionados! Keynote speakers: Florence Niedergang (Cochin) and Raphael Valdivia (Duke)- plenty of opportunities for early career researchers to present their work and a very collegial and supportive network. Belfast here we go! Please repost.

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 joanne@pitt.edu. 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
