摘要:

文题释义:

细胞外囊泡样颗粒:此处特指中草药囊泡,即从中药细胞外液或中药汁液中分离得到的纳米级脂质双层囊泡。这些囊泡具有与哺乳动物外泌体相似的形态和功能,它们由磷脂双分子层构成,包含蛋白质、核酸和脂质等生物活性成分,能够在细胞间传递生物信息,发挥多种生物学功能。中草药囊泡因其来源广泛、产量高、生物相容性好且毒性低等优点,成为中药现代化研究的热点之一,尤其在抗炎、抗氧化等领域展现出巨大的应用潜力。
金银花:作为中国传统中药材,金银花的主要化学成分包括黄酮类、环烯醚萜类、三萜及三萜皂苷类、有机酸类、挥发油等多种类型。这些成分赋予了金银花广泛的药理作用,如抗炎、抗菌、抗病毒、抗氧化、保肝利胆、降血糖、降血脂、增强免疫和止血等。

摘要
背景:近年来,纳米技术在抗炎治疗中展现出潜力,但纳米药物系统在生产成本、工艺复杂性和生物安全性方面仍面临挑战。中草药囊泡技术作为潜在改良手段,具有来源丰富、生物相容性优良等优点,成为中医药领域新兴的研究热点。
目的:探讨金银花源性细胞外囊泡样颗粒的抗炎生物活性及机制。
方法:采用超速离心法提取金银花源性细胞外囊泡样颗粒,并对其进行鉴定。通过CCK-8法、流式细胞术和共聚焦显微镜评估RAW264.7细胞对金银花源性细胞外囊泡样颗粒的摄取能力及生物相容性。建立脂多糖诱导的RAW264.7细胞炎症模型,研究金银花源性细胞外囊泡样颗粒对炎症递质和巨噬细胞表型的影响并使用转录组学揭示金银花源性细胞外囊泡样颗粒的抗炎机制。

结果与结论:①金银花源性细胞外囊泡样颗粒的粒径主要集中在(79.42±23.12) nm,具有典型的杯状囊泡结构和膜结构,且在模拟胃肠消化环境中表现出良好的稳定性;②金银花源性细胞外囊泡样颗粒对RAW264.7细胞无毒性,8 h摄取率超过90%;③在炎症模型中,金银花源性细胞外囊泡样颗粒能显著降低白细胞介素6、白细胞介素1β和环氧化酶2水平,抑制巨噬细胞向M1型极化,并回调降低的白细胞介素10、CD206水平;④转录组学分析表明,金银花源性细胞外囊泡样颗粒可能通过调节肿瘤坏死因子、核因子κB和Toll样受体等关键炎症信号通路发挥抗炎作用。这些结果表明金银花源性细胞外囊泡样颗粒具有显著的抗炎活性,为其作为新型抗炎药物递送系统提供了实验依据,有望为炎症性疾病的治疗提供新选择。

Abstract: BACKGROUND: Recently, nanotechnology has shown potential in anti-inflammatory treatment, but nanodrug systems face challenges in production costs, process complexity, and biosafety. Chinese herbal medicine-derived vesicle technology, with advantages like abundant sources and good biocompatibility, has emerged as a new research hotspot in traditional Chinese medicine.
OBJECTIVE: To explore the anti-inflammatory biological activity and mechanism of Lonicera japonica Thunb.-derived extracellular vesicle-like particles.
METHODS: Lonicera japonica Thunb.-derived extracellular vesicle-like particles were extracted using ultracentrifugation and characterized. The uptake of Lonicera japonica Thunb.-derived extracellular vesicle-like particles by RAW264.7 cells and their biocompatibility were evaluated using CCK-8 assays, flow cytometry, and confocal microscopy. A lipopolysaccharide-induced RAW264.7 cell inflammation model was established to investigate the effects of Lonicera japonica Thunb.-derived extracellular vesicle-like particles on inflammatory mediators and macrophage phenotypes. Transcriptomics was used to elucidate the anti-inflammatory mechanisms of Lonicera japonica Thunb.-derived extracellular vesicle-like particles.
RESULTS AND CONCLUSION: (1) Lonicera japonica Thunb.-derived extracellular vesicle-like particles had a particle size of (79.42±23.12) nm, with typical cup-shaped vesicle and membrane structures, and showed good stability in simulated gastrointestinal digestion. (2) Lonicera japonica Thunb.-derived extracellular vesicle-like particles were non-toxic to RAW264.7 cells, with an uptake rate exceeding 90% after 8 hours. (3) In inflammatory models, Lonicera japonica Thunb.-derived extracellular vesicle-like particles significantly reduced interleukin-6, interleukin-1β and cyclooxygenase-2 levels, inhibited M1 macrophage polarization, and restored interleukin-10 and CD206 levels. (4) Transcriptomic analysis suggests that Lonicera japonica Thunb.-derived extracellular vesicle-like particles exert anti-inflammatory effects by modulating key inflammatory signaling pathways such as tumor necrosis factor, nuclear factor κB, and Toll-like receptors. These findings demonstrate significant anti-inflammatory activity of Lonicera japonica Thunb.-derived extracellular vesicle-like particles, providing experimental evidence for their potential as a novel anti-inflammatory drug delivery system and offering a new option for treating inflammatory diseases.
