Peptide hydrogels could help heal traumatic brain injuries

Traumatic brain injury (TBI) — defined as a bump, blow or jolt to the head that disrupts normal brain function — sent 2.5 million people in the U.S. to the emergency room in 2014. Today, researchers report a self-assembling peptide hydrogel that, when injected into the brains of rats with TBI, increased blood vessel regrowth and neuronal survival.
