| Outline of Final Research Achievements |
Fluid-percussion-induced injury on the brain was produced in rats. The increase in blood-brain barrier permeability and resulting brain edema was detected in the penumbra area. The HMGB1 translocation from nuclei to extracellular space was observed in neurons in injured region. BBB disruption, activation of microglia, and the increase in the expression of inflammatory cytokines were observed in the same region. The treatment with anti-HMGB1 mAb inhibited the inflammatory response induced by injury by 85%, associated with the improvement of neurological symptoms. Glycyrrhizin, an active constituent of licorice that binds to HMGB1, produced a similar activity to anti-HMGB1 mAb. The inhibitory effects of glycyrrhizin on traumatic brain injury was not observed in RAGE knockout mice, suggesting the involvement of RAGE in the action of HMGB1 released from neurons. Similarly, anti-HMGB1 mAb improved the paralysis of hind limb dramatically due to the prevention of blood-spinal cord barrier.
