Introduction: Chemotherapy plays an important role in antitumour therapy, but causes serious adverse reactions. So, drug delivery system (DDS) with cell-targeting ability is an important method to reduce adverse reactions while ensuring the effectiveness of chemotherapy. Synthetic drug carriers and DDSs based on cells have proven safety and efficacy, but they also have many deficiencies or limitations. Cell membrane capsules (CMCs), which are based on extracellular vesicles (EVs), are a promising biomimetic DDS that retains some cell membrane channels and cytoplasmic functions, with escape macrophage phagocytosis.
Areas covered: The EVs for constructing CMCs can be prepared by natural secretion, chemical-induced budding, nanofilter membrane extrusion and similar methods and are isolated and purified by a variety of methods such as centrifugation and liquid chromatography. CMCs can target the tumour cells either spontaneously or through targeting modifications using proteins or aptamers to actively target the tumour cells. CMCs can be directly wrapped with chemicals, photosensitizers, RNA, proteins and other ingredients, or they can be loaded with antitumour agent-loaded synthetic nanoparticles, which are delivered to the target cells to play a specific role.
Expert opinion: This review describes the concept, function, characteristics, origins, and manufacturing methods of CMCs and their application in antitumour therapy. 相似文献
目的 研究复方木尼孜其颗粒联合异维A酸胶囊治疗痤疮患者的临床效果。方法 选取2020年1月-2021年6月我院就诊的160例痤疮患者为研究对象,按照随机数字表法分为观察组和对照组,各80例。对照组予以异维A酸胶囊治疗,观察组予以复方木尼孜其颗粒联合异维A酸胶囊治疗。于治疗后8周,比较两组临床疗效、皮损程度评分及不良反应发生率。结果 观察组治疗总有效率高于对照组(92.50% vs 70.00%),差异有统计学意义(P<0.05);观察组皮损程度评分低于对照组,差异有统计学意义(P<0.05);观察组不良反应发生率低于对照组(11.25% vs 28.75%),差异有统计学意义(P<0.05)。结论 复方木尼孜其颗粒联合异维A酸胶囊治疗痤疮的临床效果良好,不仅能有效改善患者的皮损程度,还能降低不良反应发生率,促进病情康复。 相似文献
