VIH et Chlamydia : quand la co-infection transforme les macrophages en refuge

Les co-infections par le VIH-1 et Chlamydia trachomatis sont bien documentées au niveau épidémiologique, mais leurs interactions au sein des cellules restent mal comprises. Dans une étude publiée…

🤩 Really happy our publication in mSphere showing how #HIV and #Chlamydia trachomatis join forces to survive inside #macrophages! lnkd.in/ejNj66PE Strong collaboration between our group @institutcochin.bsky.social Paris and Maria-Teresa Damiani's group @CONICET @UniversidadNacionaldeCuyo, Argentina

It was a great pleasure and honor to start the @ukcellmicro.bsky.social annual meeting today in Belfast! Wonderful programme with talks and posters on various #microbes and #hosts ! Thank you again for inviting me !

Great start to session1 at the 28th Club Exo-Endo meeting!Three exciting talks, from lipid control of dopamine D2 receptor(D.Perrais, Bordeaux), to Vamp7-dependent cholesterol trafficking (P.Nazac,Paris) and how biomechanics shape membrane trafficking in neurons (D. des Roberts, Bordeaux)

Session 4 explored how cells communicate and coordinate organelles, with Sophie Rome, Julia Dancourt, Stéphane Bodin and Céline Knorr covering macrophages, EV fate, secretory autophagy and ER–lysosome contacts. @clubexo-endo.bsky.social

Session 3 of the Club Exo endo meeting explored how intracellular architecture shapes cell function, with Quentin Frenger, Jacky Goetz, Leo Krüttli and Aline Mathey highlighting autophagy, lysosome positioning, cilia remodeling and cancer cell migration.

Session 3 explored how intracellular architecture shapes cell function: from autophagosome biogenesis and lysosome positioning to ciliary membrane remodeling and endolysosomal dynamics in cancer cell migration. @clubexo-endo.bsky.social

What a start for the second day of the Club Exo Endo meeting with keynote speaker C.Leterrier who uses state-of-the art superresolution microscopy to resolve axonal cytoskelon organization. Hot spots of endocytosis and exocytosis in clearings free of actin and spectrin. Fascinating talk!

Session2 at the 28th Club Exo Endo meeting offers great talks spanning phagocytosis (F.Niedergang, Paris), phagolysosome resolution (Q.Provôt, Paris), retromer coat assembly (N.Gopaldass, Lausanne), and fast endophilin-mediated endocytosis in cell invasion (E. Sekretova, Grenoble).

Chris Murphy@chrismurphyct.bsky.social · 8mo ago

I can't believe I'm posting this video - but we actually have to have a conversation about the real world implications of America going to war over Greenland. Let me walk you through it. It doesn't turn out well for us.

I am delighted to introduce our new Centre of Excellence in Immune-Endothelial Interfaces (IMMENs) funded by the Research Council of Finland. www.helsinki.fi/en/researchg... I will be recruiting two postdocs early next year. One image analyst and one biologist interested in working on lymphatics!

Centre of Excellence in Immune - Endothelial Interfaces (IMMENs) | University of Helsinki

The overarching aim of IMMENs, a Research Council of Finland funded Centre of Excellence, is to understand how local immune responses are regulated at the lymphatic endothelium-immune cell interface.

End-of-the year PHAG'IC lab @institutcochin.bsky.social dinner yesterday with most of the lab members and excellent food from various regions to share! thank you all for your scientific engagement and great team spirit!

Thank you @Adriana Mantegazza for the invitation to give a seminar @ThomasJeffersonUniversity and great opportunities to discuss with you, your colleagues and early career researchers #cellbiology #immunity #viruses #macrophages - forgot to take a picture during this intense day!

two posters @jcellsci.bsky.social collected at the @biologists.bsky.social booth during the #cellbio2025 meeting @ascbiology.bsky.social @embo.org are now in place in the lab @institutcochin.bsky.social in Paris!

Hooray, @biologists.bsky.social have protected a tree in exchange for a peer review I did for J Cell Sci. One of the many reasons why I prefer to donate my time to them rather than a commercial publisher. forest.biologists.com/landscape/?i...

Happy to share that I will be presenting at #CellBio2025 this afternoon during the #CSCB session in room 108 our work on #phagocytosis by #macrophages mannose receptor done @institutcochin.bsky.social by @chiarapompili.bsky.social with @jfattaccioli.bsky.social and @jean-Maurice Mallet

it's been almost 2 weeks since the farewell party ending Hannah von Giesen's @uniheidelberg.bsky.social internship in our PHAGI'IC team @institutcochin.bsky.social : congratulations for these 2 awsome months and the best of luck for the future projects on #immunity @rockefeller.edu !
