From stroke rehabilitation to spinal cord healing to Alzheimer’s intervention, researchers are advancing therapies that rethink how we repair the nervous system—especially in cases once considered beyond recovery.
In this week’s roundup, we feature three promising directions in neurorestoration: a plant-derived compound that activates IGF-1 signaling for axonal repair after stroke, a novel scaffold that stimulates the body’s own stem cells to regenerate severed spinal cords, and brain-penetrant antibodies designed to target Alzheimer’s pathology more effectively and safely. Together, they highlight the growing momentum behind therapies aimed at restoring, not just relieving, long-term neurological function.
1. IGF-1 signaling pathway activation promotes axonal regeneration and repair: A mechanism study on catalpol-induced functional recovery after ischemic stroke
Researchers found that catalpol, a compound derived from traditional medicine, activates the IGF-1 signaling pathway to support axonal regeneration and neurological recovery after stroke—pointing to a promising direction for post-stroke repair.
2. DON-Apt19S bioactive scaffold transplantation promotes in situ spinal cord repair in rats with transected spinal cord injury by effectively recruiting endogenous neural stem cells and mesenchymal stem cells
A novel scaffold combining DNA aptamer Apt19S with a decellularized optic nerve matrix successfully recruited both neural and mesenchymal stem cells to fully transected spinal cord injuries in rats—resulting in in situ regeneration, vascularization, synapse formation, and improved motor function without cell transplantation.
3. Bispecific brain-penetrant antibodies for treatment of Alzheimer’s disease
A new generation of bispecific antibodies engineered to cross the blood-brain barrier shows enhanced ability to target Alzheimer’s pathology—including amyloid, tau, and inflammation—while reducing side effects and enabling earlier, lower-dose treatment.
