| Research Abstract |
High mobility group box-1 （HMGB1 ）has been paid much attention as an important damage-associated molecular pattern. I established anti-HMGB1 antibody therapy for ischemic brain injury and brain vasospasm. In the present study, I examined whether anti-HMGB1 antibody therapy may exert beneficial effects on traumatic brain injury in rats. The results showed that HMGB1 in neurons at injured site was translocated and released into extracellular space. The administration of anti-HMGB1 antibody inhibited the disruption of blood-brain barrier and resulting brain edema. Anti-HMGB1 antibody therapy will be beneficial for the treatment of traumatic brain injury.
