目前正在开发用于成像和治疗应用的下一代靶向纳米器件。我们设计了 HK97 病毒纳米颗粒 (VNP),用于肿瘤细胞特异性靶向。开发并应用遗传和化学工程方法的组合来生成显示转铁蛋白和荧光标记的双标记 HK97 半胱氨酸突变体颗粒。使用不同癌细胞系的体外实验评估了转铁蛋白缀合的 VNP 的靶向特性。我们发现 HK97-转铁蛋白制剂确实通过转铁蛋白受体在体外靶向癌细胞。这些研究强调了基于 HK97 的 VNP 的实用性并促进了其进一步发展。
Next-generation targeted nanodevices are currently under development for imaging and therapeutic applications. We engineered HK97 viral nanoparticles (VNPs) for tumor cell-specific targeting. A combination of genetic and chemical engineering methods were developed and applied to generate dual-labeled HK97 cysteine mutant particles displaying transferrin and fluorescent labels. The targeting properties of transferrin-conjugated VNPs were evaluated by in vitro experiments using different cancer cell lines. We found that HK97–tranferrin formulations were indeed targeted to cancer cells in vitro via the transferrin receptor. These studies highlight the utility and facilitate the further development of HK97-based VNPs.
