Outline of Final Research Achievements

In this study, we found that various natural antifungals such as farnesol, which is a component of plant-derived essential oils, induced the intracellular production of nitric oxide (NO) in Aspergillus fumigatus, and that the NO production was involved in the antifungal action of farnesol. Moreover, A. fumigatus was revealed to highly express the efflux pump, Cdr1B, and reduce the intracellular farnesol in response to farnesol.

Academic Significance and Societal Importance of the Research Achievements

本研究によって、精油成分に対する糸状菌のNO産生を介した応答分子機構の一端を明らかにした。近年、広く利用される人工合成の抗真菌薬に対する病原糸状菌の耐性株出現が問題となっている。NO産生を誘導しない抗真菌薬とは異なり、NO産生を誘導する天然抗菌性ファルネソールに対する糸状菌の応答および排出機構を明らかにする本研究により、これまでの抗真菌薬とは異なる作用機序をもつ新規な薬剤開発の一助となることが期待される。
