虽然基因治疗在医学上前景广阔,但它需要递送剂来保护和靶向核酸治疗剂。我们利用自组装豇豆褪绿斑驳病毒(CCMV)开发了植物病毒 siRNA 传递平台。 CCMV 装载有针对 GFP 或 FOXA1 的 siRNA;为了进一步增强细胞摄取和细胞内运输,从而实现更有效的基因敲除,我们在 CCMV 上附加了细胞穿透肽 (CPP),特别是 M-番茄毒素肽 L17E。
While highly promising in medicine, gene therapy requires delivery agents to protect and target nucleic acid therapeutics. We developed a plant viral siRNA delivery platform making use of self-assembling cowpea chlorotic mottle virus (CCMV). CCMV was loaded with siRNAs targeting GFP or FOXA1; to further enhance cell uptake and intracellular trafficking, resulting in more efficient gene knockdown, we appended CCMV with a cell penetrating peptide (CPP), specifically M-lycotoxin peptide L17E.
