Researchers discovered a neuroprotective mechanism in spinal cord injury (SCI) involving microglia, the brain’s immune cells, which could provide new therapeutic targets. Using advanced in vivo imaging, the team revealed that microglia form protective wraps around injured axons, preventing further damage. This interaction, regulated by P2Y12 receptors and sodium channels, sheds light on neuron-glia communication after injury. The study's insights into spinal cord protection could eventually lead to new treatments for SCI and related neurological diseases.
