Macrophage-derived oncostatin M repairs the lung epithelial barrier during inflammatory damage Tissue repair programs must function alongside antiviral immunity to restore the lung epithelial barrier following infection. We found that macrophage-derived oncostatin M (OSM) counteracted the patho...

#WeekendRead! #InterferonsFriendsOrFoes?! @ruthfranklinlab.bsky.social, Medzhitov, Hoagland, Rodriguez-Morales &co show @science.org that macrophage-derived oncostatin M overcomes type I IFN detrimental responses during severe influenza lung infection by driving AT-II epithelial cell proliferation!

This is remarkable

Intruiging preprint using #singlecell genomic profiles of treated and untreated #IPF patients to identify a "therapeutic gap" of established anti-fibrotic treatments and implicating STAT3 in IPF pathogenesis. Have a look 👇

Finally out as reprint!!!
"Alveolar epithelial cell plasticity & injury memory in human pulmonary fibrosis".
Glad to share the results of our single nuc-seq & single cell ATAC-seq analyses of human IPF & PCLS before peer review - see the key findings in 🧵👇🏽

Human Lung Alveolar Model with an Autologous Innate and Adaptive Immune Compartment Lung-resident immune cells, spanning both innate and adaptive compartments, preserve the integrity of the respiratory barrier, but become pathogenic if dysregulated[1][1]. Current in vitro organoid mo...

I enjoyed reading this very cool preprint over the weekend - congratulations @graycamplab.bsky.social and Laurian Cabon, should be a very powerful tool for the field 😍

Great to be front page news! Congratulations @jennydickens41.bsky.social Read the paper here: www.embopress.org/doi/full/10....

Super cool an intriguing work by the group of @hansclevers.bsky.social - A human organoid model of alveolar regeneration reveals distinct epithelial response to interferon-gamma

www.biorxiv.org/content/10.1...

Awesome and super helpful - thank you so very much!

I am aware of he amazing work of @andreasmoor.bsky.social and his group - but I didn’t find anything comparable in humans!

Looking for sc or snRNA-seq datasets/studies in humans that specifically profile #eosinophils or contain a substantial number of them!

If you have any leads, please share! And if you don’t but know someone who might, please re-post so it reaches the right people :)
Many, many thanks!

Congratulations!
