Macrophages are crucial players in inflammation-induced pulmonary fibrosis, but the mechanisms driving macrophage polarisation and their specific roles in pulmonary fibrosis pathogenesis remain poorly understood. Here, we demonstrate that both YAP and TAZ are activated in lung macrophages from patients with pulmonary fibrosis as well as in mice with bleomycin-induced pulmonary fibrosis. Myeloid-specific <i>Yap/Taz</i> deletion resulted in reduced recruitment of monocyte-derived alveolar macrophages (Mo-AMs), impaired inflammatory responses, decreased pulmonary fibrosis and enhanced alveolar epithelial cell regeneration following bleomycin treatment. Conversely, the expression of a constitutively active YAP mutant (YAP<sup>5SA</sup>) exacerbated bleomycin-induced pulmonary fibrosis by increasing Mo-AM recruitment, elevating expression of pro-inflammatory and pro-fibrotic markers, and impairing alveolar epithelial cell regeneration. We demonstrate that YAP/TAZ-CCL2 (C-C motif chemokine ligand 2) signalling plays a crucial role in bleomycin-induced pulmonary fibrosis, as blocking CCL2 with a neutralising antibody effectively abrogated the YAP<sup>5SA</sup>-induced recruitment of Mo-AMs, inflammatory and fibrotic responses. Additionally, we reveal that the YAP/TAZ-MBD2-TGFβ1-pSMAD2 signalling axis is crucial not only for pro-fibrotic macrophage polarisation, but also for their cross-talk with lung fibroblasts, driving the fibroblast-to-myofibroblast transition. Collectively, these findings suggest that targeting aberrant YAP/TAZ activity to modulate inflammatory and fibrotic response could be a promising strategy for the prevention and treatment of pulmonary fibrosis.</p>","PeriodicalId":12265,"journal":{"name":"European Respiratory Journal","volume":" ","pages":""},"PeriodicalIF":16.6,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12138047/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143364103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We hypothesized that ITIH4 is implicated in PM-related emphysema.METHODSWe investigated the association between ITIH4 expression and ambient PM exposure through a clinical cohort analysis (220 patients with COPD and 61 healthy participants) and in vitro studies.MEASUREMENTS AND MAIN RESULTSThe COPD cohort studies revealed significant correlations between emphysema severity, ambient PM exposure, and serum ITIH4 levels. In primary small airway epithelial cells from COPD patients with low basal levels of ITIH4, exposure to PM and oxidative stress led to increased apoptosis. However, ITIH4 overexpression significantly inhibited oxidative stress-induced apoptosis in normal and COPD airway epithelial cells. Acute exposure to hydrogen peroxide resulted in the rapid degradation of ITIH4 protein with no effect on transcriptional level, although ITIH4 gene expression is downregulated in the lung tissue of patients with COPD. A human apoptosis antibody array revealed that ITIH4 overexpression attenuated hydrogen peroxide-induced apoptotic signaling. Furthermore, extracellular ITIH4 protein confers cytoprotective functions in cells exposed to PM or oxidative stress. Mechanistically, ITIH4 attenuated oxidative stress-induced JNK activation and β-catenin decrease. A deficiency of ITIH4 exacerbated the effects of oxidative stress.CONCLUSIONSWe identified a novel pathogenetic mechanism involving ITIH4, where chronic exposure to air pollution induces or promotes emphysema.","PeriodicalId":12265,"journal":{"name":"European Respiratory Journal","volume":"57 1","pages":""},"PeriodicalIF":24.3,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144122053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We sought to characterize renal dysfunction in PAH and CTEPH and to assess the effect of pulmonary hypertension treatment on renal function.METHODSWe performed an individual participant data meta-analysis of 6694 participants from 18 phase III randomized clinical trials of pulmonary hypertension therapies. We calculated estimated glomerular filtration rate (eGFR) using the race-agnostic 2021 CKD-EPI equation.RESULTSThe mean age was 49.6±15.5 years, 78% were female and 58% had idiopathic PAH. A total of 907 participants (13.5%) had a baseline eGFR<60 mL·min-1·1.73 m-2. Lower baseline eGFR correlated with higher mean right atrial pressure (mRAP) and lower cardiac index. At 12-16 weeks, a 10 mmHg decrease in mRAP from baseline or a 1 L·min-1·m-2 increase in cardiac index was associated with only a 1.7 mL·min-1·1.73 m-2 (95% CI: -2.9, -0.5; p=0.006) or a 1.4 mL·min-1·1.73 m-2 (95% CI: 0.5, 2.4; p=0.003) increase in eGFR, respectively. A 10 mL·min-1·1.73 m-2 lower baseline eGFR was associated with an increased risk of all-cause mortality (aHR: 1.16 [95% CI:1.08, 1.23]; p<0.001).
