I was a guest on Ann Mogilevsky's podcast. We spoke about the pulmonary manifestations of scleroderma, my clinical experiences caring for patients with chronic lung disease, and current research efforts to better understand pulmonary fibrosis. podcasts.apple.com/us/podcast/epi…

@TatsuyaTsukui Congratulations @TatsuyaTsukui. This is very important and high quality work. It will be interesting to determine what endogenous molecular brakes might mitigate this transition - and their cellular origins - during normal resolution and how this fails in progressive fibrosis.

The origin of pathologic fibroblasts in diseases has long been controversial. We lineage-traced alveolar fibroblasts by scRNA-seq and found that all emergent fibroblast subsets (profibrotic, inflammatory, etc.) after fibrotic injury originated from alveolar fibroblasts.

We generated a new mouse tool, Scube2-creER, which specifically labeled alveolar fibroblasts but not other subsets such as Pi16+ adventitial fibroblasts. Whole lung imaging showed alveolar fibroblasts were everywhere throughout the parenchyma, close to AT2 cells.

Thrilled and honored to receive the teaching award for the abdominal division from our graduating 2024 residents!! You all are the reason I’m here and love my job. Thank you, you’ll never know how much it means to me. @UMichRadiology

Exciting work indeed. This drug works quite elegantly. Instead of inhibiting TGF-beta signaling outright (which has dire consequences), latent TGF-beta activation is mitigated by inhibiting integrins expressed on lung epithelial cells, influencing the intended physiologic context

A great step for #CureIPF!!! INTEGRIS-IPF, a phase IIa #RCT suggests that Bexotegrast, an αvβ6 & αvβ1 inhibitor has safety & dose-dependent efficacy. Can't wait for Phase III results. Kudos Drs Lancaster, Flaherty, #IntegrisIPF team & @ATSBlueEditor! doi.org/10.1164/rccm.2…

Both receptors ligated by survodutide signal via increasing intracellular cAMP. Interesting and encouraging to see antifibrotic and antiinflammatory actions of this second messenger in other organs outside of the lung.
NEJM@NEJM

In this phase 2 trial involving adults with metabolic dysfunction–associated steatohepatitis and liver fibrosis, survodutide was superior to placebo with respect to improvement in MASH without worsening of fibrosis. Full trial results: nej.md/4bBXQPF #EASLCongress

Really great work guys!

As #ATS2024 ends, we’re excited to release our new tool, AlveolEye, a free app which uses machine learning to make lung morphometry rigorous and less time consuming – a tool made by two amazing students Sam and Joe Hirsh, and @shawyonshirazi from the Sucre Lab @sucre_jen 🧵1/5

A @NatureCareers feature highlights how new data repositories and alternative journals and workshops offer routes for sharing negative results, which could help to solve the reproducibility crisis and give machine learning a boost. go.nature.com/3WEfmhH

Importantly, neither of the two FDA approved drugs for IPF - pirfenidone and nintedanib - inhibited p38 or promoted dedifferentiation of myofibroblasts (a requisite step for resolution), thus their actions distinguishing from the cAMP/MKP1/p38α pathway. 4/n

The persistent lung fibrosis associated with fibroblast-specific deletion of MKP1 was associated with marked changes in epithelial cells and macrophage infiltration. 3/n
