Abstract Spinal cord injury (SCI) causes severe neurological dysfunction and currently has no effective treatment. Due to the complex pathophysiological processes associated with SCI and the limited efficacy of single strategies, the need for combined strategies for effective SCI therapy is becoming increasingly apparent. In this study, we evaluated the combined effects of layered double hydroxide-coupled NT3 (MgFe-LDH/NT3) nanoparticles (NPs) and ultrasound (US) both in vitro and in vivo. Combined treatment promoted neural stem cell (NSC) differentiation into neurons and exerted anti-inflammatory effects in vitro. Furthermore, combined therapy promoted behavioural and electrophysiological performance at eight weeks in a completely transected murine thoracic SCI model. Additional RNA sequencing revealed that ultrasonic-induced Piezo1 downregulation is the core mechanism by which combined therapy promotes neurogenesis and inhibits inflammation, and the Piezo1/NF-κB pathways were identified. Hence, the findings of this study demonstrated that the combination of ultrasound and functional NPs may be a promising novel strategy for repairing SCI. |
