Leading follow-up research on CCN1 therapeutic applications

For decades, doctors told paralyzed patients that severed spinal cords cannot heal. That dogma is crumbling. Researchers at Cedars-Sinai Medical Center have identified a previously unknown repair system in the spinal cord: support cells called astrocytes, located far from the injury site, release a protein signal that reprograms immune cells to clear debris and enable recovery. The findings, published in Nature in February 2026, open therapeutic pathways for treating paralysis, stroke, and multiple sclerosis.
