Engineered Exosomal miRNAs for Post-Stroke Neural Repair: Mechanisms, Delivery Strategies, and Translational Challenges
This review systematically summarizes the multi-target mechanisms by which exosomal miRNAs regulate the neurovascular unit (NVU) and outlines technical strategies to enhance exosomal therapeutic efficacy through targeted modification and engineered cargo loading, with the aim of constructing a smart drug delivery syste...
