We collected clinical specimens from COPD patients and healthy subjects. A mouse model of COPD induced by CS exposure was established in vivo. Neutrophils were isolated from the peripheral blood of human donors and exposed to CS extract in vitro. We found extensive NET formation was observed in COPD patients with a history of long-term heavy smoking and was closely related to glucocorticoid resistance. In vivo, we found that prolonged CS exposure promoted NET formation and that rendered dexamethasone (Dex) treatment ineffective at alleviating lung inflammation in COPD model mice. However, the NET degrading agent deoxyribonuclease I could increase sensitivity to Dex in COPD model mice. In vitro experiments demonstrated that CS extract increased neutrophil cell viability by activating the Nrf2/SLC7A11/GPX4 pathway and inducing ferroptosis resistance in neutrophils. And we found that neutrophil specific GPX4 knockout inhibited CS-induced NET formation, increased sensitivity to Dex, and alleviated CS-induced glucocorticoid resistance in vivo and in vitro.

However, precisely regulating the secretion of Schwann cells localized in bone injury tissue to enhance neurogenic bone regeneration remains a considerable challenge. In this study, an injectable, ultrasound-responsive piezoelectric conductive short fiber network (US@SFG) was innovatively developed using uniform short fiber homogenization techniques and multifunctional chemical modifications, enabling precise acoustic-electrical conversion that regionally activated the secretion of miRNAs from Schwann cell-derived exosomes, thereby promoting neurogenic bone regeneration. The incorporation of the piezoelectric polymer glycine imparts superior piezoelectric characteristics to the fiber network, while the conjugated π-electron motion within the conductive graphene network enhances internal electron transfer efficiency, thereby facilitating electrical conductivity. Compared with traditional piezoelectric fiber networks, acousto-electric conversion fiber networks demonstrated a 1.7-fold increase in piezoelectric performance and a 30-fold increase in conductivity, facilitating precise electrochemical regulation under ultrasound stimulation. In vitro studies revealed that acousto-electric conversion fiber networks precisely modulate the secretion of localized Schwann cell exosomal miRNAs (miRNA-494-3p, miRNA-381-3p, and miRNA-369-3p), activating the phosphatidylinositol 3-kinase/protein kinase B and Wnt signaling pathways in bone marrow mesenchymal stem cells, and thereby promoting osteogenic differentiation. Furthermore, in vivo experiments confirmed that under ultrasound imaging guidance, acousto-electric conversion fiber networks could be directed precisely to bone defects, where precise control of ultrasound parameters facilitated acoustic-electrical conversion and electrical signal modulation, markedly promoting the formation of neural networks and bone tissue regeneration.

The cohesin complex comprises 4 core subunits, namely, SMC1, SMC3, RAD21, and STAG, and notably, it plays pivotal roles in controlling the fate determinations of stem cells by facilitating the dynamic regulation of the 3-dimensional genome architecture. We have recently reported that RAD21 forms a complex with YAP1 and NEDD4 to promote the self-renewal of human spermatogonial stem cells and inhibit their apoptosis. In this review, we address the molecular properties of the cohesin complex and its multiple regulatory mechanisms in mediating the fate decisions of various kinds of stem cells, including hematopoietic stem cells, embryonic stem cells, spermatogonial stem cells, neural stem cells, and other types of stem cells. By maintaining the chromatin loop structure, the cohesin complex is involved in DNA repair and gene transcription, which in turn controls the pluripotency, self-renewal, and differentiation of stem cells. In addition, the cohesin complex ensures faithful DNA replication and sister chromatid cohesion, which indirectly supports genetic and epigenetic programs. Variants in the subunit components of the cohesin complex and proteins' modifications further confer functional plasticity, and its mutations can lead to abnormal stem cell functions and are correlated with diseases including cancers. Future studies need to integrate multidisciplinary approaches including single-cell multi-omics and cryo-electronic microscopy to resolve the dynamic regulatory networks of the cohesin complex in stem cell fate regulation and further explore its potential applications in regenerative and reproductive medicine.</p>","PeriodicalId":21120,"journal":{"name":"Research","volume":"8 ","pages":"0757"},"PeriodicalIF":11.0,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12245137/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144609205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we report for the first time that IL-27, via JAK1-STAT1 signaling, up-regulates indoleamine 2,3-dioxygenase (IDO) in MSCs, driving MSC differentiation toward an IDO-positive MSC2 phenotype with low immunogenicity. These IDO-positive MSC2 cells produce kynurenine and kynurenic acid, the metabolites of tryptophan, which bind to the intracellular aryl hydrocarbon receptor. This interaction stimulates an increase in the anti-inflammatory factor TSG-6 and induces the differentiation of regulatory T cells. Notably, IL-27-conditioned MSC2 demonstrated superior therapeutic efficacy compared to conventional MSCs in a murine lupus nephritis model.

However, the mechanical strength and injectability of CPCs often remain insufficient for load-bearing applications, limiting their broader use in these critical procedures. To address this challenge, we introduce a machine learning-assisted approach to enhance both the mechanical strength and injectability of CPCs by identifying specific polymers as superplasticizers. By optimizing its concentration and the liquid-to-powder (L/P) ratio, we developed an injectable brushite-based cement with an exceptional compressive strength of 79.5 ± 4.3 MPa, surpassing both traditional CPCs and PMMA in orthopedic applications.

In mouse models, GPR120 expression in the mammary gland increases markedly during lactation.

These benefits were also observed under non-inflammatory conditions and were diminished when GPR120 was knocked down. Furthermore, the regulatory function of GPR120 under non-inflammatory conditions in in vivo and in vitro models is explored. We discovered that the GPR120-Gα<sub>s</sub>-cyclic adenosine monophosphate (cAMP)-exchange protein directly activated by cAMP (EPAC) signaling axis is critical for lipogenesis and migration in mammary epithelial cells.
