Inflammatory monocytes constrain YAP-induced cell proliferation
Singh S, Tahmasian N, Liu J, Wang W, Haas L, Zhu Y, Griswold M, Brodsky N, Liu S, Kalish B, Yimlamai D. Inflammatory monocytes constrain YAP-induced cell proliferation. Science Advances 2026, 12: eaee8580. PMID: 42341114, PMCID: PMC13292995, DOI: 10.1126/sciadv.aee8580.Peer-Reviewed Original ResearchThis study investigates how YAP and TAZ, key regulators of cell growth, drive opposing immune responses with TAZ promoting tumor growth and YAP being constrained by inflammatory monocytes.Hepatocyte CYR61 polarizes profibrotic macrophages to orchestrate NASH fibrosis
