[Abstract] Synthetic nanoparticle-based drug delivery system is widely known for its ability to increase the efficacy and specificity of loaded drugs, but it often suffers from relatively higher immunotoxicity and higher costs as compared to traditional drug formulations. Contrarily, plant-derived nanoparticles appear to be free from these limitations of synthetic nanoparticles; they are naturally occurring biocompatible vesicles that do not generate immunotoxicity and are easy to obtain. Additionally, lipids isolated from plant-derived nanoparticles have shown the capability of assembling themselves to spherical nano-sized liposomal particles. Herein, we employ lipids extracted from ginger-derived nanoparticles and load them with therapeutic siRNA (CD98-siRNA) to create CD98-siRNA/ginger-lipid ...
[摘要] [摘要 ]基于合成纳米颗粒的药物递送系统以其增加所载药物的功效和特异性的能力而广为人知，但是与传统药物制剂相比，它经常遭受相对较高的免疫毒性和较高的成本。相反，植物来源的纳米粒子似乎不受合成纳米粒子的这些限制；它们是天然存在的生物相容性囊泡，不会产生免疫毒性并且易于获得。另外，从植物来源的纳米颗粒分离的脂质已显示出将其自身组装成球形纳米尺寸脂质体颗粒的能力。在本文中，我们采用从生姜纳米颗粒中提取的脂质，并用治疗性siRNA（CD98-siRNA）加载脂质，以创建CD98-siRNA /生姜脂质纳米颗粒。CD98-siRNA /姜脂脂质纳米颗粒的表征显示它们呈球形，直径约为189.5 nm。纳米颗粒的表面ζ电势在-18.1至-18.4mV之间变化。此外，在最近的研究中，CD98-siRNA /姜脂纳米颗粒在右旋糖酐硫酸钠（DSS）诱发的结肠炎小鼠模型中显示出特定的结肠靶向能力和出色的抗炎功效。
[背景 ] 小干扰RNA（siRN As）是一种有前途的治疗剂，可以通过沉默异常上调的信使RNA（mRNA）来治疗各种疾病（Nikam and Gore ，2018）。尽管siRNA的有效性，安全有效地将siRNA递送至治疗靶标仍然是一项艰巨的任务（Tatiparti et al ...
