Additionally, these approaches are frequently associated with significant adverse effects. Inspired by the success of CAR-T cell therapy in oncology, this review examines the potential of CAR-T cell technology for treating heart diseases, detailing how CAR-T cells, engineered by merging antibody-derived targeting domains with T-cell signaling domains. The technology's core includes an extracellular antigen-binding domain, hinge region, transmembrane domain, and intracellular signaling domain, with the single-chain variable fragment (scFv) playing a crucial role in antigen recognition. The paper delves into the immune mechanisms in cardiovascular diseases like heart failure, hypertension, and myocardial infarction, focusing on the roles of T cells in promoting myocardial fibrosis and the therapeutic potential of regulatory T cells (Tregs) in recovery phases. Additionally, it explores the use of lipid nanoparticles (LNPs) carrying mRNA to produce transient, non-integrative CAR-T cells targeting fibroblast activation protein (FAP) to reduce myocardial fibrosis, a method showing promise in preclinical models by enhancing cardiac function and reducing ventricular fibrosis. Despite its potential, the study acknowledges challenges in clinical translation, such as limited therapeutic effects and severe inflammatory responses, highlighting the need for further optimization and research in CAR-T cell technology for cardiovascular disease treatment.</p>","PeriodicalId":23187,"journal":{"name":"Tohoku Journal of Experimental Medicine","volume":" ","pages":"145-152"},"PeriodicalIF":1.7,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142591494","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}

Combining OCP with various polymeric biomaterials enhances its ductility, making it suitable for clinical applications, including dentistry. Preclinical studies on OCP/gelatin (OCP/Gel) composites have shown excellent osteoconductive and osteoinductive properties, indicating potential for bone defect repairs. This study investigates the efficacy of OCP/Gel as a filler for lumbar interbody fusion cages. A miniature swine model underwent surgery using polyetheretherketone (PEEK) cages with different fillers: no filler, autologous rib, and OCP/Gel. Eight weeks post-surgery evaluations using computed tomography, histological assessments, and Fourier transform infrared (FT-IR) spectroscopy revealed that while PEEK cages without fillers showed no bone fusion, those with autologous rib and OCP/Gel demonstrated partial interbody fusion. Histological analysis indicated new bone growth in cages with OCP/Gel, and FT-IR spectroscopy confirmed the degradation of OCP at the vertebral interface and increased bone matrix proteins. The findings suggest that OCP/Gel could be a viable alternative to autologous bone grafts for lumbar interbody fusion surgeries, offering less invasive and more cost-effective solutions. The success of OCP/Gel in clinical applications could pave the way for broader use in orthopedic reconstructive surgeries, potentially eliminating the need for combined use of bone marrow aspirate or expensive growth factors.</p>","PeriodicalId":23187,"journal":{"name":"Tohoku Journal of Experimental Medicine","volume":" ","pages":"135-144"},"PeriodicalIF":1.7,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142740734","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}

Previous studies have shown that PE is associated with changes in vascular endothelial cells, but the specific mechanism is unclear. In this study, we assessed the effects of chemokine C-X-C-motif receptor 4 (CXCR4) on endothelial cells and explored the potential mechanisms. Human placental microvascular endothelial cells (HPVEC) were exposed to protein Z (PZ), qRT-PCR and Western blotting were used to detect the expression of proliferation related genes and proteins, such as PI3K/Akt/ERK. Meanwhile, qRT-PCR and Western blotting were used to detect the expression of anticoagulation markers PGI2 and t-PA. Then, HPVEC were transfected with CXCR4 siRNA or NC siRNA. The expression of proliferation related genes and proteins were also detected. Finally, PZ and CXCR4 were co-cultivated with different fluorescent labels, the binding sites of the two proteins were observed under confocal laser scanning microscopy (CLSM). PZ promoted the proliferation and expression of anticoagulant markers PGI2 and t-PA in HPVEC. CXCR4 silencing could inhibit the proliferation of HPVEC which stimulated by PZ. CLSM showed that the binding site of PZ and CXCR4 was located on the cell membrane. In conclusion, our results suggested that PZ promote the expression of PGI2/t-PA and affect the PI3K/Akt/ERK signaling pathway by binding with CXCR4 which improved our understanding of the molecular mechanisms involved in HPVEC.</p>","PeriodicalId":23187,"journal":{"name":"Tohoku Journal of Experimental Medicine","volume":" ","pages":"121-125"},"PeriodicalIF":1.7,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142814242","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}

Conventional treatments may not always be effective or may have considerable side effects. Warm yang and promote diuresis blood-activating method (WYLBAM), a traditional intervention, has been proposed as a complementary approach for CHF, but its clinical efficacy and impact on cardiac function have not been systematically evaluated. We performed a comprehensive meta-analysis to assess the clinical efficacy of WYLBAM for CHF. Following PRISMA guidelines, databases were searched for clinical trials comparing WYLBAM with standard care. Data on clinical efficacy rate, left ventricular ejection fraction (LVEF), left ventricular end-diastolic and end-systolic dimensions (LVEDD and LVESD), 6-minute walk test, and biomarkers BNP and NT-proBNP were extracted. Heterogeneity was assessed using the I² statistic, and publication bias was evaluated with funnel plots and sensitivity analyses. Our search yielded 947 records, with 26 studies included after screening and eligibility assessment. Meta-analysis demonstrated a significant improvement in clinical efficacy rate, LVEF, LV dimensions, and 6-minute walk test distances in patients treated with WYLBAM. Biomarkers BNP and NT-proBNP also improved significantly, indicating a potential reduction in cardiac stress. The I² values suggested substantial heterogeneity, which was addressed through random-effects modeling. Publication bias was not evident in the funnel plot analyses. WYLBAM may be a beneficial adjunctive treatment for improving cardiac function and physical capacity in patients with CHF. However, the presence of heterogeneity suggests that individual patient factors should be considered when applying WYLBAM. Further well-designed large-scale RCTs are warranted to confirm these findings and to explore the underlying mechanisms of action.</p>","PeriodicalId":23187,"journal":{"name":"Tohoku Journal of Experimental Medicine","volume":" ","pages":"107-119"},"PeriodicalIF":1.7,"publicationDate":"2025-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141761072","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}
