Reparative hydrogel mimics the composition and mechanics of the brain
At a cost of $38 billion a year, an estimated 5.3 million people are living with a permanent disability related to traumatic brain injury in the United States today, according to the Centers for Disease Control and Prevention. The physical, mental and financial toll of a TBI can be enormous, but new research from the University of Georgia provides promise.
In a new study, researchers at UGA’s Regenerative Biosciences Center have demonstrated the long-term benefits of a hydrogel, which they call “brain glue,” for the treatment of traumatic brain injury. The new study provides evidence that not only does the gel protect against loss of brain tissue after a severe injury, but it also might aid in functional neural repair.
Brain damage following significant TBI commonly results in extensive tissue loss and long-term disability. There currently are no clinical treatments to prevent the resulting cognitive impairments or tissue loss.
Reported on March 5 in Sciences Advances, the new finding is the first to provide visual and functional evidence of the repair of brain neural circuits involved in reach-to-grasp movement in brain glue-implanted animals following severe TBI.
“Our work provides a holistic view of what’s going on in the recovery of the damaged region while the animal is accomplishing a specific reach-and-grasp task,” said lead investigator Lohitash Karumbaiah, an associate professor in the University of Georgia’s College of Agricultural and Environmental Sciences.
