英文摘要：

Background/Objectives:Glioblastoma is a highly aggressive brain tumor with limited treatment options and poor prognosis. Signal Transducer and Activator of Transcription 3 (STAT3) plays a crucial role in glioblastoma progression, making it a promising therapeutic target. However, effective delivery of STAT3-silencing agents across the blood–brain barrier remains a significant challenge. This study evaluates the efficacy of Lipid Nanoparticles-EXOSOME COMPLEX STAT3-silencer treatment in reducing glioblastoma tumor growth by facilitating efficient small interfering RNA delivery and inhibiting STAT3 expression.Methods:A novel exosome-based drug delivery system was developed using NLP-EXOSOME COMPLEX nanoparticles loaded with STAT3-silencer siRNA. The therapeutic efficacy was assessed in vitro using human glioblastoma cell lines and in vivo using a glioblastoma mouse model. Tumor progression, STAT3 expression levels, and survival rates were analyzed.Results:The results demonstrated that Lipid Nanoparticles-EXOSOME COMPLEX effectively transported STAT3-silencer siRNA into glioblastoma cells, leading to significant STAT3 downregulation. This resulted in reduced tumor proliferation, increased apoptosis, and extended survival in vivo. The combination of lipid nanoparticles and exosomes provided a stable and efficient delivery mechanism with improved uptake and therapeutic efficacy.Conclusion:Lipid Nanoparticles-EXOSOME COMPLEX STAT3-silencer treatment offers a promising approach for targeted glioblastoma therapy by overcoming the blood–brain barrier limitations and enhancing STAT3 inhibition. Further research is necessary to optimize long-term efficacy, assess potential immune responses, and explore combinatory therapeutic strategies for improved patient outcomes.

**背景/目的：** 胶质母细胞瘤是一种高度侵袭性脑肿瘤，治疗手段有限且预后不良。信号转导与转录激活因子3（STAT3）在胶质母细胞瘤进展中起关键作用，使其成为潜在的治疗靶点。然而，STAT3沉默剂如何有效跨越血脑屏障递送仍是一大挑战。本研究旨在评估脂质纳米颗粒-外泌体复合物STAT3沉默剂治疗通过促进小干扰RNA高效递送并抑制STAT3表达，从而减少胶质母细胞瘤生长的效果。 **方法：** 本研究开发了一种基于外泌体的新型药物递送系统，采用负载STAT3沉默剂siRNA的NLP-外泌体复合物纳米颗粒。通过体外人类胶质母细胞瘤细胞系和体内胶质母细胞瘤小鼠模型评估其治疗效果，分析肿瘤进展、STAT3表达水平及生存率。 **结果：** 结果显示，脂质纳米颗粒-外泌体复合物能有效将STAT3沉默剂siRNA递送至胶质母细胞瘤细胞，显著下调STAT3表达。这导致肿瘤增殖减少、细胞凋亡增加，并在体内延长了生存期。脂质纳米颗粒与外泌体的结合提供了稳定高效的递送机制，增强了细胞摄取和治疗效果。 **结论：** 脂质纳米颗粒-外泌体复合物STAT3沉默剂治疗通过克服血脑屏障限制并增强STAT3抑制，为靶向胶质母细胞瘤治疗提供了有前景的新策略。未来需进一步研究以优化长期疗效、评估潜在免疫反应，并探索联合治疗策略以改善患者预后。
