We have demonstrated that SOX17, a member of the SRY-Box (SOX) transcription factor family, affects pulmonary artery vascular homeostasis through exosomes in an autocrine and paracrine manner. However, the role of SOX17 in mediating EndMT of pulmonary arterial endothelial cells (PAECs) in PH and its underlying intracellular mechanisms are not yet clarified. Here, we show that in the remodeling pulmonary vascular of idiopathic PH patients and Sugen 5416/hypoxia (Sugen/hypoxia)-induced PH rats, the downregulation of SOX17 expression was accompanied by a significant pulmonary arterial EndMT and TGF-β/Smad2/3 signaling activation. In primary HPAECs, the expression of SOX17 was inhibited by canonical TGF-β signaling. SOX17 overexpression reversed TGF-β- and hypoxia-induced EndMT. It is suggested that SOX17 is required for HPAECs to acquire TGF-β-mediated EndMT. Mechanistically, SOX17 prevented TGF-β-induced EndMT of PAECs through trans-suppressing ROCK1 expression by binding to the specific promoter region of ROCK1, thereby inhibiting the phosphorylation of MYPT1 and MLC. Further, we found that Tie2-Cre rats with endothelial cell-specific SOX17 overexpression were prevented from Sugen/hypoxia-induced EndMT and pulmonary vascular remodeling. In keeping with the in vitro data, compared with the Tie2-Cre rats treated by Sugen/hypoxia, the rats with SOX17 overexpression showed decreased expression of ROCK1 as well as the MYPT1 and MLC phosphorylation. Overall, our studies demonstrate a novel TGF-β/SOX17/ROCK1 pathway regulating EndMT of PAECs and propose SOX17 as a potential target for exploring therapeutics to alleviate pulmonary vascular remodeling in PH.</p>","PeriodicalId":7655,"journal":{"name":"American Journal of Respiratory Cell and Molecular Biology","volume":" ","pages":""},"PeriodicalIF":5.9,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142399133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, our understanding of the inflammatory response in patients with ARDS is mainly based on assessment of the systemic compartment and preclinical studies. Investigations into the intricate network of immune cells and their critical functions in the alveolar compartment remain limited. However, with recent improvements in single cell analyses, our comprehensive understanding of the interactions between immune cells in the lungs has improved. In this review, we summarize the current knowledge about the cellular composition and interactions of different immune cell types within the alveolar space of patients with ARDS. Neutrophils and macrophages are the predominant immune cells in the alveolar space of ARDS patients. Yet, all immune cells present, including lymphocytes, participate in complex interactions, coordinate recruitment, modulate the lifespan and control apoptosis through various signaling pathways. Moreover, the cellular composition of alveolar immune cells is associated with clinical outcomes of ARDS patients. In conclusion, this synthesis advances our understanding of ARDS immunology, emphasizing the crucial role of immune cells within the alveolar space. Associations between cellular composition and clinical outcomes highlight the significance of exploring distinct alveolar immune cell subsets. Such exploration holds promise for uncovering novel therapeutic targets in ARDS pathophysiology, presenting avenues for enhancing clinical management and treatment strategies for ARDS patients.
