From plant-derived compounds to precision light therapy, scientists are uncovering fresh ways to help the brain and spinal cord heal after injury or disease. Recent studies show that a natural molecule from herbs can guide brain cells into repair mode after stroke, an Alzheimer’s antibody can shift key disease biomarkers in promising directions, and light-activated transplanted cells can restore movement after spinal cord injury.
Together, these findings highlight how diverse strategies—from harnessing nature’s chemistry to engineering the nervous system’s circuitry—are shaping the future of neurorehabilitation and neuroprotection.
1. Icaritin promotes brain functional rehabilitation in ischemic stroke rats by regulating astrocyte activation and polarization via GPER
In a rat model of ischemic stroke, the plant compound Icaritin improved motor skills, memory, and gait by shifting astrocytes from a damaging inflammatory state to a protective, repair-focused mode via the GPER pathway. This shift reduced brain inflammation, encouraged neuron regeneration, and supported long-term recovery.
2. Erratum to “Biofluid biomarker changes following treatment with sabirnetug (ACU193) in INTERCEPT-AD, a phase 1 trial in early Alzheimer’s disease” [J Prev Alzheimers Dis 2025;12(4): 100082]
In a phase 1 study, the Alzheimer’s antibody sabirnetug lowered key cerebrospinal fluid and blood biomarkers linked to tau buildup, synaptic damage, and neurodegeneration. These changes grew with higher doses and longer exposure, supporting further testing in larger, longer trials.
3. Fetal rat neural progenitor cell transplantation after spinal cord injury improves motor recovery following optogenetic stimulation
Researchers found that transplanting neural progenitor cells into rats with spinal cord injuries—and then stimulating them daily with targeted blue light—significantly improved motor coordination, speed, and stability. This optogenetic approach boosted cell survival, enhanced neural connections, and reduced harmful inflammation, offering a potential path toward better recovery strategies for spinal cord injury patients.
