Motor dysfunction and muscle atrophy are typical symptoms of patients with spinal cord injury (SCI). Exercise training is a conventional physical therapy after SCI, but exercise intervention alone may have limited efficacy in reducing secondary promoting nerve regeneration functional remodeling. Our previous research found that intramedullary pressure SCI one the key factors affecting prognosis. It has been reported GsMTx-4, specific blocker mechanosensitive ion channels Piezo1, can protect integrity neuromuscular junction promote regeneration, thus potential as therapeutic agent for SCI. In this study, we observed combined separate effect GsMTx-4 on structure soleus motor function rats At 42 days post-injury, compared rats, Basso–Beattie–Bresnahan score (P = 0.0007) Gait Symmetry 0.0002) were significantly improved combination therapy.

Abstract Bone repair in real time is a challenging medical issue for elderly patients; this mainly because aged bone marrow mesenchymal stem cells (BMSCs) possess limited osteogenesis potential and capacity. In study, triboelectric stimulation technology used to achieve via mechanosensation of Piezo1 by fabricating wearable pulsed nanogenerator (WP‐TENG) driven human body movement. A peak value 30 µA has the optimal effects rejuvenate BMSCs, enhance their osteogenic differentiation, promote umbilical vein endothelial cell tube formation. Further, previous studies demonstrate that WP‐TENG can reinforce BMSCs angiogenesis (HUVECs). Mechanistically, are rejuvenated mechanosensitive ion channel Piezo1. Thus, enhanced formation capacity HUVECs improved, which further confirmed augmented regeneration vivo investigations. This study provides signal transduction mechanism rejuvenating theoretical basis using generated WP‐TENG.

Healing bone defects in patients with type 2 diabetes mellitus (T2DM) has long been a challenging issue. Elevated blood sugar levels T2DM lead to the overproduction of reactive oxygen species (ROS), which negatively affects mitochondrial function, induces senescence marrow mesenchymal stem cells (BMSCs), and diminishes their osteoblastic potential. In this study, we developed polyacrylic acid modified cerium oxide nanoparticles (PCNPs), biocompatible, water-soluble, antioxidant nanozyme. Our vitro experiments demonstrated that PCNPs effectively eliminated ROS, restored significantly upregulated AMPK-SIRT1-PGC1α signaling pathway, ultimately mitigating BMSCs senescence. Considering clinical applications, have also investigated synergistic effects material systems for sustained release vivo. This sustained-release system proved be more effective promoting defect healing rats. These findings introduce promising innovative approach managing using customized multifunctional nanozymes.
