The role of extracellular vesicles (EVs), such as exosomes and microvesicles, as active carriers of NLRP3 signaling components is increasingly being recognized, as they modulate the tumor microenvironment as well as distant tissues primed for metastasis. This study will address the diverse roles of EV-mediated NLRP3 signaling in cancer immunopathogenesis, with a particular emphasis on its role in establishing a pre-metastatic niche and immune evasion. Tumor-derived EVs that include NLRP3 as cargo can reprogram stroma and immune cells at secondary sites in the body to support a metabolic role associated with metastatic colonization. While tumor-derived EVs promote extracellular matrix remodeling, angiogenesis, and the recruitment of immune-suppressive cells, this cascade of processes permits the development of a permissive niche for metastatic colonization, and simultaneously impairs anti-tumor immune surveillance. The provided EV-mediated crosstalk also enables tumor cells to evade immune detection through the downregulation of antigen-presenting cells and the activation of immune-suppressive pathways via NLRP3-dependent mechanisms. The molecular mechanisms underlying EV-driven inflammasome signaling could pave the way for the identification of a novel and specific biomarker, in which its modulation could potentially affect the immune system in the tumor microenvironment (TME) and participate in cancer immunopathogenesis. This review highlights the need to dissect further the interactions and context-specific roles of EV-NLRP3 across cancers to identify new therapeutic strategies for preventing metastasis and enhancing immune therapies.</p>","PeriodicalId":12227,"journal":{"name":"Experimental cell research","volume":" ","pages":"114778"},"PeriodicalIF":3.5,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145206082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During proliferation, SMCs utilize glutamine to fulfill their energy, biosynthesis, and redox needs. Glutaminase C (GAC), a splice variant of glutaminase (GLS), catalyzes the hydrolysis of glutamine to glutamate, which is ultimately used in the TCA cycle. Although GAC is known to stimulate the proliferation of human cancer cells, endothelial cells, and fibroblasts, its role in SMC proliferation and neointimal hyperplasia remains elusive. This study explores the role of the therapeutic potential of targeting GAC during SMC proliferation and neointimal hyperplasia. To assess the role of GAC on the proliferation of SMCs, murine aortic SMCs were treated with CB-839 (selectively inhibits GAC activity; 10 μM) for 60 min. SMCs were stimulated with Platelet-Derived Growth Factor-BB (PDGF-BB; 20 ng/ml) for 24 h. Using Western blotting and immunofluorescence, we report that GAC expression was significantly higher in SMCs stimulated by PDGF-BB and in the neointima of wire-injured mice as compared to the control. Deprivation of glutamine in the media impeded the proliferation and migration of SMCs. Pretreatment of SMCs with GAC inhibitor reduces PDGF-BB-induced SMC migration, proliferation, and phenotypic switching. GAC inhibition was associated with decreased phosphorylation of ERK and mTOR.

Although a cell-based assay using primary human trophoblasts has been developed to identify compounds that inhibit sFLT1 secretion, routine application of this assay is limited owing to the complexity of isolating these cells from the placenta and their inability to be passaged.

In the present study, we investigated whether hTSC-differentiated STBs (dSTBs) exhibit enhanced secretion of sFLT1 under hypoxic conditions, similar to primary trophoblasts. Hypoxic stimulation significantly increased sFLT1 secretion by the dSTBs.
