Can we target pulmonary fibrosis by selectively intercepting profibrotic FGF signals? Our study, now published in AJRCMB, Editor’s Choice! suggests that we can. From human lung fibroblasts to preclinical models of fibrosis 🔗 academic.oup.com/ajrcmb/artic... #PulmonaryFibrosis #IPF #LungResearch

Excellent! How does q.e.d handle references to evaluate innovative content, particularly in fields contaminated by numerous articles from low-quality journals (ie: ncRNA for instance)? Does it also evaluate sources?

7/7 Our data suggest that in a reversible fibrosis model, sCap are recruited and can act as progenitor cells to reconstitute the gCap pool to regenerate the integrity of the alveolar endothelial capillaries while aging appears to delay this process. 🙏 to our supports @agencerecherche.bsky.social

6/7 We also found that aging altered the transcriptome of gCap in control mice, with a signature suggestive of a pro-fibrotic and pro-inflammatory state, that may participate in the dysfunction of other cells in the alveolar niche and impede alveolar regeneration.

5/7 RNA velocity approach indicated that following lung injury, sCap are recruited and may function as progenitor cells that can initiate a differentiation process, transiting through Lrg1+ gCap before reaching the physiological gCap cell state.

4/7 These systemic EC corresponds to two distinct populations: one with venous macrovascular origin previously defined as SV EC and a second one lacking typical macrovascular and venous markers, corresponding to systemic capillary EC (sCap), in agreement with a recent study in COVID patients.

3/7 .. we identified aging-associated changes in PCEC pops, including aCap and gCap, shifting towards a pro-angiogenic phenotype expressing Lrg1 and associated with alveolar niche regeneration, as well as the emergence of homologous Col15a1-positive systemic EC previously identified in IPF
