在“实验生物学与医学”(第242卷,第14期,2017年8月)发表的一篇文章报道说,可以使用基于植物病毒的系统来递送抗癌药物。研究由Nicole Steinmetz博士领衔,位于俄亥俄州克利夫兰的Case Western Reserve大学工程与医学学院生物医学工程系生物医学系,该研究表明,由烟草花叶病毒和vcMMAE组成的复合物,一种治疗淋巴瘤的一线化疗药物,可杀死癌细胞。



基于植物病毒的抗癌药物递送系统】在“实验生物学与医学”(第242卷,第14期,2017年8月)发表的一篇文章报道说,可以使用基于植物病毒的系统来递送抗癌药物。研究由Nicole Steinmetz博士领衔,位于俄亥俄州克利夫兰的Case Western Reserve大学工程与医学学院生物医学工程系生物医学系,该研究表明,由烟草花叶病毒和vcMMAE组成的复合物,一种治疗淋巴瘤的一线化疗药物,可杀死癌细胞。

超过80万美国人患有淋巴瘤(淋巴系统癌症)。非霍奇金淋巴瘤(NHL)是淋巴瘤最常见的类型,此病患者的预后差。 NHL的一线治疗策略是化疗。然而,这种方法与目标外的副作用相关。正在开发纳米载体以改善药物递送并使与抗癌药物相关的脱靶效应最小化。然而,许多这些系统在药物递送中的用途可能受其球形的限制。延长的纳米材料可能优于其球形对应物,因为增加靶细胞相互作用和减少的免疫细胞摄取。然而,高度均匀的细长纳米材料的合成是具有挑战性的,

目前的研究使用含有植物病毒烟草花叶病毒(TMV)成分的天然衍生的组合来克服与合成系统相关的问题。 TMV与用于治疗NHL的缬氨酸 - 瓜氨酸单甲基auristatin E(vcMMAE)前体药物生物缀合。所得的TMVvcMMAE复合体进入NHL癌细胞,在其中被切割以释放活性药物并杀死癌细胞。 Steinmetz博士说:“每种平台技术为药物传递提供独特的优势;基于植物病毒的纳米技术可以通过植物中的分子养殖以高产量生产,基于蛋白质的材料在生物培养基中稳定,生物相容的纳米级脚手架提供无与伦比的工程机会允许引进各种医疗货物,虽然在开发阶段的早期,基于植物病毒的药物传播系统为下一代药物传递提供了一个有趣的平台技术。

Stein R.Goodman博士,实验生物和医学主编,他说:“Steinmetz和他的同事利用植物病毒TMV作为将缬氨酸 - 瓜氨酸单甲基auristatin E(vcMMAE)前体药物递送到人类B细胞NHL的体外模型,观察细胞摄取,内体细胞位置和可能的前体药物切割以及细胞杀伤,这些研究为进一步测试这种用于癌症治疗的植物病毒药物递送系统提供了动力。
