北京大学第三病院の李墨教授率いる研究チームは、内臓器官への精密な薬物・遺伝子送達を可能にする電池不要の柔軟なナノ流体パッチ「NanoFLUID」を開発し、その成果を『Nature』誌に発表しました。この技術は、従来の送達法が直面していた生体内の障壁を克服し、単一細胞レベルでの高効率かつ低毒性の治療を実現します。肝障害モデルでは組織再生を促進し、乳がんモデルでは高精度な治療効果を示しました。さらに、肺転移を促進する遺伝子DUS2を特定するなど、基礎研究への応用も期待されています。この技術は、がんや臓器不全などの慢性疾患治療に新たな道を開く可能性があります。

Abstract

The targeted delivery of therapeutics to internal organs to, for example, promote healing or apoptosis holds promise in the treatment of numerous diseases1,2,3,4. Currently, the prevailing delivery modality relies on the circulation; however, this modality has substantial efficiency, safety and/or controllability limitations5,6,7,8,9. Here we report a battery-free, chipless, soft nanofluidic intracellular delivery (NanoFLUID) patch that provides enhanced and customized delivery of payloads in targeted internal organs. The chipless architecture and the flexible nature of thin functional layers facilitate integration with internal organs. The nanopore–microchannel–microelectrode structure enables safe, efficient and precise electroperforation of the cell membrane, which in turn accelerates intracellular payload transport by approximately 105 times compared with conventional diffusion methods while operating under relatively low-amplitude pulses (20 V). Through evaluations of the NanoFLUID patch in multiple in vivo scenarios, including treatment of breast tumours and acute injury in the liver and modelling tumour development, we validated its efficiency, safety and controllability for organ-targeted delivery. NanoFLUID-mediated in vivo transfection of a gene library also enabled efficient screening of essential drivers of breast cancer metastasis in the lung and liver. Through this approach, DUS2 was identified as a lung-specific metastasis driver. Thus, NanoFLUID represents an innovative bioelectronic platform for the targeted delivery of payloads to internal organs to treat various diseases and to uncover new insights in biology.
