An injection of nanoparticles can prevent the body’s immune system from overreacting to trauma, potentially preventing some spinal cord injuries from resulting in paralysis.
The approach was demonstrated in mice at the University of Michigan, with the nanoparticles enhancing healing by reprogramming the aggressive immune cells—call it an “EpiPen” for trauma to the central nervous system, which includes the brain and spinal cord.
“In this work, we demonstrate that instead of overcoming an immune response, we can co-opt the immune response to work for us to promote the therapeutic response,” said Lonnie Shea, the Steven A. Goldstein Collegiate Professor of Biomedical Engineering.
