You want it held back: restraining emt protects organ architecture and function.
In depth
Epithelial-to-mesenchymal transition — the program by which orderly tissue cells turn migratory, driving fibrosis and organ scarring.
What drives it
Cell fate signaling increases it.
EMT-and-invasion review 2013 — Notch signaling activates Snail/Slug/ZEB repressors of E-cadherin, driving epithelial-to-mesenchymal transition. PMID 24278531
Tissue renewal signaling increases it.
Lamouille 2014, Nat Rev Mol Cell Biol — canonical Wnt stabilizes β-catenin (via GSK3β inhibition), which engages TCF/LEF to induce the Snail/Twist EMT program. PMC4372086
Reduces scarring increases it.
Ramachandran 2018, eLife — tgf-β-induced epithelial-to-mesenchymal transition requires smad signaling (SMAD3 with SMAD1/5). Doi:10.7554/eLife.31756. TGF-beta is the most potent factor engaged to initiate and complete emt. emt and its reverse, met, both occur during physiological wound healing as well as pathological fibrosis — emt is not intrinsically pathological, and the same transition serves repair. doi 10.7554/eLife.31756.
What it drives
It reduces Kidney.
Lovisa 2015, Nat Med 21:998 — tubular epithelial cells undergo a partial EMT program in renal fibrosis, arresting in G2 and downregulating solute transporters, causing parenchymal damage and loss of renal function. PMID 26236991

It increases Clears blocked nose & sinuses.
This is the same axis as eczema, and it splits the same way: type 2 endotypes are IL-4/IL-5/IL-13-driven and eosinophilic, while non-type-2 endotypes ARE driven by increased Th1 and Th17 responses, resulting in elevated neutrophil levels. Two endotypes, two cell types, two nodes. And the intervention evidence is unusually direct: dupilumab (IL-4Ralpha inhibitor) reduces polyp burden and restores smell, while MEPOLIZUMAB (anti-IL-5) and OMALIZUMAB (anti-IgE) address specific endotypes - three biologics, three targets, three endotype-matched responses.
