'Zombie cells' hold clues to spinal cord injury repair

Mammals have a poor ability to recover after a spinal cord injury, which can result in paralysis. A main reason for this is the formation of a complex scar associated with chronic inflammation that produces a cellular microenvironment ...

Studies reveal skull as unexpected source of brain immunity

The immune system is the brain's best frenemy. It protects the brain from infection and helps injured tissues heal, but it also causes autoimmune diseases and creates inflammation that drives neurodegeneration.

Cell reprogramming could aid spinal cord injury recovery

Cells called astrocytes normally support our neurons, and now scientists are working to reprogram the star-shaped cells into neurons that help reconnect the brain and body after a spinal cord injury.
