Immune responses controlled by Toll-like receptor 4 (TLR4) are closely associated with the host response to pathogens, including Mtb. NLRP3 inflammasome-mediated pyroptosis forms a significant part of the inflammatory response during Mtb infection, and endoplasmic reticulum stress (ERS) is implicated in the activation of the NLRP3 inflammasome. Here, the function of TLR4 in macrophage pyroptosis induced by infection with the Bacillus Calmette-Guérin (BCG) mycobacterial strain was investigated. It was found that infection with BCG activated TLR4 signaling, induced ERS and subsequent NLRP3 inflammasome activation, leading to pyroptosis in mouse lung tissues. The TLR4 inhibitor TAK 242 inhibited the ERS onset, NLRP3 inflammasome stimulation, and pyroptosis, while the ERS inhibitor TUDCA blocked both inflammasome activation and pyroptosis, and the NLRP3 inhibitor MCC950 specifically inhibited pyroptosis. Furthermore, TAK 242, TUDCA, and MCC950 all exacerbated lung injury caused by BCG infection and promoted BCG survival. Similarly, after in BCG-infected THP-1 macrophages, TLR4 signaling was found to mediate NLRP3 inflammasome activation through ERS, thereby inducing pyroptosis. In summary, BCG infection leads to macrophage pyroptosis via the TLR4/ERS/NLRP3 inflammasome signaling axis, providing new insights for further research into the pathogenesis and treatment of tuberculosis.</div></div>","PeriodicalId":13859,"journal":{"name":"International immunopharmacology","volume":"152 ","pages":"Article 114346"},"PeriodicalIF":4.8,"publicationDate":"2025-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143577189","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}

However, few studies have shown its material basis and mechanism of action, so this article mainly focuses on these two issues. Rats were stimulated by fan blowing and low temperature for 7 days, following which alkaloid extract (SWJ), non-alkaloid extract (FSWJ), and polysaccharide extract (DT) from <em>Ephedra sinica</em> (MH) were administered for 4 days. First, the body temperature, sweat spots, activity status, and cough-related indexes were detected to screen the pharmacodynamic material basis of MH. Then, the immune cells, ROS, MDA, GSH-PX, SOD, IL-4, IgE, TRPM8, TLR4, p-P65/P65, acetylcholine, and CHRM3 levels were detected to explore the potential mechanism of the SWJ. In addition, BEAS-2B cells were cultured at 26 °C for 12 h to establish a cell injury model induced by cold stimulation. BEAS-2B cells were co-cultured with spleen cells, and the effects of ephedrine (MHJ) and pseudoephedrine (WMHJ) on immune cells and inflammatory factors in this system were detected. The TRPM8 inhibitor (AMG-333) was added 3 h before administration to detect the effects of MHJ and WMHJ on the expression levels of TRPM8, TLR4, and P-P65/P65. Animal experiments showed that SWJ, FSWJ, and DT reduced body temperature and relieved symptoms such as sweating difficulty, listlessness, and cough, and SWJ produced the best effect. Subsequently, it was found that SWJ transformed immune cells, weakened oxidative stress, downregulated IL-4, IgE, TRPM8, TLR4, and P-P65/P65, and upregulated ACH and CHRM3. Cell experiments showed that MHJ and WMHJ upregulated the Ths and Tcs and downregulated IL-6, TNF-α, TRPM8, TLR4, and P-P65/P65. The intervention of AMG-333 affected the TRPM8 and p-P65/P65, but AMG-333 did not regulate TLR4. Taken together, alkaloid extract is the material basis for MH to improve rats' wind-chill cold and may protect rats from injury by regulating the TRPM8/TLR4-NFκB pathway and CHRM3, with ephedrine and pseudoephedrine possibly playing an important role.</div></div>","PeriodicalId":13859,"journal":{"name":"International immunopharmacology","volume":"152 ","pages":"Article 114432"},"PeriodicalIF":4.8,"publicationDate":"2025-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143577097","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}

However, clinical translation of these methods faces challenges due to manufacturing complexities and emerging safety concerns like unintended long deletions and chromosomal loss. In this study, we explored an alternative approach by engineering synthetic CD3 subunits containing an endoplasmic reticulum retention (ERR) signal to suppress TCR surface expression by disrupting its trafficking to the plasma membrane. We screened multiple CD3-ERR candidate designs to identify the construct with the highest efficacy in TCR downregulation. The selected candidate, CD3ζ-ERR, was further characterized, demonstrating its ability to minimize TCR-mediated activation and alloreactivity without affecting T cell phenotype, cell cycle and cytokine-induced expansion. Subsequent assays revealed that CD3ζ-ERR CD19 CAR T cells retained their CAR-mediated cytotoxic function against CD19⁺ malignant cells.
