Herein, we constructed an H1 ESC strain with reduced METTL3 expression using lentivirus-delivered short hairpin (sh) RNA and generated hESC-NK cells via a two-stage differentiation system. Our findings demonstrated that METTL3 knockdown in hESCs reduced the proportion of hematopoietic stem and progenitor cells (HSPCs, CD34<sup>+</sup> cells) during embryoid bodies (EBs) formation, and impaired subsequent differentiation into mature NK cells. Moreover, ESC-NK cells derived from shMETTL3-ESC (called shMETTL3-ESC-NK) showed impaired anti-tumor activity, evidenced by downregulation of mRNA and protein levels of critical effectors (perforin, granzyme B and IFN-γ) and reduced cytotoxicity against target cells. Furthermore, both mRNA and protein levels of T-BET and EOMES were significantly down-regulated in shMETTL3-ESC-NK cells. These transcription factors are critical for NK cell development and cytotoxicity, and their downregulation may underlie the maturation defects of shMETTL3-ESC-NK cells.

Programmed death ligand 1 (PD-L1) expression in the TME inhibits CAR-T cell function, limiting persistence and cytotoxic capacity. To address this, we engineered CD19/BCMA-targeted CAR-T cells co-expressing a PD1IL7R chimeric switch receptor (CSR). This novel receptor converts PD-L1-mediated inhibitory signals into IL7R-driven pro-survival and proliferative pathways, enhancing CAR-T cell expansion, persistence, and cytotoxicity in a PD-L1–dependent but antigen-specific manner. In vitro, CD19/BCMA-PD1IL7R CAR-T cells exhibit improved central memory T-cell formation, increased cytokine secretion, and superior antitumor activity compared to conventional CAR-T cells. Notably, these functional enhancements were evident even at low levels of PD-L1 expression on target cells, and no off-target effects were observed. Our findings suggest that incorporating the PD1-IL7R switch receptor into CAR-T cells effectively overcomes PD-L1–mediated immunosuppression, enhancing both their persistence and antitumor efficacy.

Nevertheless, there is a shortage of data pertaining to the impact of lncRNA TP73-AS1 and let-7e-5p on this disease. Therefore, we aimed to explore the possible effects of aerobic exercise (AE) on lncRNA TP73-AS1, let-7e-5p, inflammation, and high mobility group box 1 (HMGB1)/receptor for advanced glycation end products (RAGE) in asthma mouse models. HMGB1/RAGE was significantly upregulated in asthma mouse models using ovalbumin (OVA) stimulation. The overexpression of let-7e-5p, which was found to be significantly downregulated in asthma mouse models, appeared to inhibit EMT and might alleviate airway inflammation in asthmatic mice through the suppression of the HMGB1/RAGE pathway. Aerobic exercise was associated with reduced airway inflammation and remodeling in asthmatic mice, and appeared to suppress TP73-AS1 expression in asthma OVA-mouse models. Furthermore, TP73-AS1 may exacerbate airway inflammation and remodeling in OVA-induced asthmatic mice by downregulating let-7e-5p expression, which could activate the HMGB1/RAGE-NF-κB pathway. These findings suggest potential innovative approaches for asthma management, which warrant further validation.</div></div>","PeriodicalId":9795,"journal":{"name":"Cellular immunology","volume":"414 ","pages":"Article 104990"},"PeriodicalIF":3.7,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144240096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
