用于改进中枢神经系统药物递送的新型纳米技术

【Abstract】

This presentation will elucidate the challenges, complexities and recent advancements pertaining to the delivery of therapeutic molecules to extrahepatic tissues facilitated by novel nanoscale drug delivery system (nanoDDS). NanoDDSs have emerged as mainstream nanoscale carriers for a diverse array of therapeutic cargoes, including peptides, nucleic acids, and gene-editing tools, ushering in novel therapeutic paradigms. However, while these systems have demonstrated efficacy in hepatic tissue, extending their delivery capabilities to extrahepatic targets presents formidable challenges, particularly in tissues characterized by intricate biological barriers such as the central nervous system.To address this challenge, integrated strategies are being devised, encompassing fine-tuning tissue specific structure-property relationship of nanoparticle, local-environment responsive release mechanisms, advanced administration devices used in clinic practice, and receptor-mediated targeting delivery systems. These approaches aim to achieve precise and efficient delivery of therapeutic cargoes to challenging tissues to achieve therapeutic benefit, while minimizing off-target effects and systemic distribution.While several strategies have been explored in early-stage clinical trials to advance viral vector-based gene therapy in extrahepatic tissues, the full potential of nanoscale delivery remains to be realized for expanding the landscape of new therapeutic modalities. Recent preclinical investigations have showcased targeted nanoparticles delivery of versatile therapeutic molecules to central nervous system in disease relevant animal models, highlighting the potential for transformative therapeutic development in a wide range of diseases. With a special focus on CNS, this presentation will cover 1) remotely controlled nanotechnology for local modulation of blood brain barriers to facilitate the delivery of biotherapeutics; 2) super-resolution method coupled with single nanoparticle tracking for unveiling the drug diffusion barrier in the CNS-extracellular space (ECS) and its physiological properties, and impact on the drug delivery. These advancements represent significant strides in the field of nanotechnology-mediated extrahepatic tissue delivery and offer promising avenues for future therapeutic innovation and clinical translation.

新型纳米级药物递送系统已成为多种治疗载荷（包括肽、核酸和基因编辑工具）的主流递送载体，从而开辟了新的治疗范式。然而，尽管这些系统在肝脏组织中显示出疗效，但将其递送能力扩展到额外肝脏靶点面临着巨大的挑战，特别是在具有复杂生物屏障的组织中，例如中枢神经系统（CNS）。为了解决这些挑战,一些创造性的协同策略正在被探索和开发。这些策略包括微调纳米颗粒的组织特异性结构-性质关系、开发局部环境响应释放机制、在临床实践中使用先进的给药装置，以及实施受体介导的靶向递送系统。这些方法的目标是实现对具有挑战性的组织的治疗载荷的精确和高效递送，最大化治疗效益，同时最小化脱靶效应和系统分布。尽管在早期临床试验中探索了多种策略以推进基于病毒载体的基因治疗在额外肝脏组织中的应用，但纳米级递送系统的全部潜力仍有待实现，以扩展新治疗方式的范围。最近的临床前研究展示了通过纳米颗粒将多种治疗分子靶向递送到疾病相关动物模型的CNS，突出显示了在广泛疾病中进行变革性治疗开发的潜力。本次演讲将聚焦CNS药物递送，内容包括：1）用于局部调节血脑屏障以促进生物治疗剂递送的远程控制纳米技术；2）结合单颗粒追踪的超分辨率方法，揭示CNS-细胞外空间（ECS）中的药物扩散屏障及其生理特性和对药物递送的影响。这些进展在纳米技术介导的额外肝脏组织递送领域代表了重要的进展，并为未来的治疗创新和临床转化提供了有希望的途径。

“芯片+医疗”在精准诊断中的研究及产业化实践

【ABSTRACT】

Chip technologies based on semi-conductor such as microfluidics, bioMEMS and so on have achieved rapid progress and broader applications. The precision, mass production and powerful integration capacity of semi-conductor technology have endowed a fully new perspective and system reconfiguration ability for precision diagnostics. This talk will share our innovative researches and industrial practices in Shenzhen, China in the recent 10 years. We have explored the “Chip+Medicine” technology platform towards the commercialization in single-molecular ultra-sensitive detection and point-of-care technology (POCT). We will exhibit the highly integration and digitalization potential of the advanced biochips, especially the huge advantages for the population of precision medicine in the field of high-sensitivity in vitro diagnostics (IVD). New concept to realize “A chip is an instrument, as well as a consumable” can be achieved based on the world-first high-efficiency monodisperse particle array and low-cost, high-precision multiple-casting processes, to enable the fast spread of nowadays expensive single-molecule detection to primary health care even finally at-home self-testing. We will briefly introduce how CAS-Envision, the spin-off from Shenzhen Institutes of Advanced Technology, Chinese Academy of Sciences (SIAT CAS), converted the intelligent patents into products and explored the commercialization approaches focusing on “Chip+Medicine”. My personal experiences and opinions on “Scientist Entrepreneurship” will be shared at the end.
