Outline of Final Research Achievements

Adenosine deaminase (ADA) is an enzyme that breaks down adenosine and deoxyadenosine. Deficiency of ADA increases the concentration of deoxyadenosine in the blood, resulting in the decrease of lymphocytes and severe immune deficiency. On the other hand, abnormalities in central nervous system development may occur. It is necessary to identify whether or not deoxyadenosine is neurotoxic. In this study, the neurotoxicity of deoxyadenosine was investigated. Deoxyadenosine was added to the culture medium of primary hippocampal cells and acute slices of striatum in mice. As a result, no significant increase in neuronal death was observed.

Academic Significance and Societal Importance of the Research Achievements

本研究の結果、デオキシアデノシンが急性に神経細胞死を引き起こす証拠は得られなかった。このことは、ADA欠損症に付随する神経発達障害は、デオキシアデノシンによる急性の神経毒性ではないことが示唆された。神経発達障害は、ADAそのものの機能の欠失、もしくは細胞分裂期におけるデオキシアデノシンの毒性などによるものと推察された。今後、細胞分裂におけるデオキシアデノシンの毒性発現の研究を進めることで、ADA欠損症における神経発達障害の機序の解明が期待される。
