Outline of Final Research Achievements

Brain injury, such as spinal cord injury (SCI), results in severe sensory and motor deficits due to the poor regenerative capacity of the adult central nervous system (CNS) primarily caused by a damaged CNS environment containing a large amount of axonal growth inhibitors, such as Nogo receptor-1 (NgR1), which inhibits axonal regrowth strongly after SCI, and its five ligands. Lateral olfactory tract usher substance (LOTUS) antagonizes NgR1 function, thereby promoting neuronal regeneration and functional recovery after SCI. In this study, we examined whether administration of purified LOTUS protein or lotus gene transfection can be useful for the clinical treatment of SCI and/or optic nerve injury. We found administration of both purified LOTUS protein and lotus gene transfection by AAV vector showed a significant effect on regeneration of injured axons and functional recovery. Thus, the data show the probability of clinical application of LOTUS for future therapy of brain injury.

Academic Significance and Societal Importance of the Research Achievements

本研究により、外来性に投与したLOTUSタンパク質またはLOTUS遺伝子導入は神経障害において有意な神経再生を惹起して機能改善に寄与することが判明したことから、未だに治療法が確立していない種々の神経障害や様々な脳疾患における軸索変性に対し、LOTUSのタンパク質製剤や遺伝子導入による治療法が奏功する可能性が示唆される。LOTUSは内在性のタンパク質であり成体の中枢神経系に豊富の発現しているが、損傷や疾患によって急激にその発現量が減少するため、LOTUSの機能不全によって神経再生が困難になると考えられる。従って、LOTUSを外来性に補填する補充療法は理に適った新たな治療法として期待される。
