Outline of Final Research Achievements

While it is considered that D-amino acids were eliminated from living organisms, we demonstrated the expression of D-amino acid, especially D-aspartic acid, in various tissues of the otorhinolaryngological field. D-aspartic acid expressed strongly in nasal polyps of eosinophilic chronic rhinosinusitis patients in the recurrence case. It was also revealed that D-aspartic acid expressed strongly in the tissue of vocal cord nodule, squamous papilloma and laryngeal cancer. It was seemed that D-aspartic acid is correlated with the pathogenesis of these diseases.

Academic Significance and Societal Importance of the Research Achievements

いままで生体内に存在しないと考えられ、その機能的役割も不明確であったD-アミノ酸が様々な疾患組織中に発現していることが示された。癌腫などの細胞が異常増殖している部位や、難治性炎症が起きていると考えられる鼻ポリープ組織や声帯結節に多く発現することが明らかとなった。この発現機序をさらに研究することにより、疾患の治療や予防に役立てることができる可能性がある。
