| Outline of Final Research Achievements |
In various intractable neural diseases, the impairment of neural vascular barriers, including blood-brain barrier, occurs and accelerates their disease progression. As the candidates for target molecules to restore the neural vascular barrier, we have specified ADAM12, ADAM17 and basigin, all of which are expressed in endothelial cells. As for ADAM12 and ADAM17, they were shown to be involved predominantly in hypoxia-induced impairment of vascular barrier, and consequently to be unable to restore sufficiently the vascular barrier in neural diseases in which various stimuli, together with hypoxia, cause the vascular barrier disruption. On the other hand, it was demonstrated that basigin is involved in the impairment of vascular barrier as the common downstream molecule of various stimuli including hypoxia and multiple cytokines, and furthermore our study with animals indicated the potential of basigin as the target to establish the new effective treatment of intractable neural diseases.
