Thrilled to share our paper "A conserved GTPase complex gates exocytosis for defence and parasitism across alveolates" Ciliates are fantastic to understand rhoptry exocytosis, and cryo-ET once again reveals so much🤩 Thanks to all who contributed. @martacova.bsky.social @yiweichang.bsky.social

Iron-sulfur proteins require specialized assembly pathways. @s-besteiro.bsky.social &co show that the plastid-derived protein HCF101 functions in the cytosolic Fe-S assembly pathway in #Toxoplasma and is crucial for #parasite viability 🧪 @plosbiology.org plos.io/3EFKKoQ

I'm thrilled to announce our latest work is now published in Cell! Viruses encode numerous proteins that inhibit host defenses, but identifying immune-modulatory proteins among millions of viral sequences has been nearly impossible - until now! www.cell.com/cell/fulltex...

Remember learning that ribosomes are made of 1 large subunit RNA + 1 small subunit RNA? Well, some cells defy this rule, and the most extreme case is Toxoplasma which makes its mitoribosome from >50 RNA pieces! Wanna know how? Read below

Delighted to share our study on a major Toxoplasma virulence factor that prevents lytic host cell death. Many thanks to @parafrap.bsky.social for support, constructive reviews and all labs involved: Melissa Lodoen, Hiba El Hajj, @gissotlab.bsky.social, Karine Le Roch Link : rdcu.be/d6m3G
