Outline of Final Research Achievements

In this study, we investigate the expression of periostin and its isoforms in refractory cases of eosinophilic chronic rhinosinusitis (ECRS) to elucidate the refractory mechanism of ECRS.
The expression of isoforms was investigated using total RNA extracted from polyp tissue of ECRS. In the nasal polyp tissue, isoform 5 had the highest expression level in all cases. The isoform expression pattern is different from that of NHLF cells, and it is considered that there is tissue specificity in nasal polyps. This suggests that isoform 5 may be involved in the formation of nasal polyps, rather than the mechanism of refractory sinusitis.

Academic Significance and Societal Importance of the Research Achievements

本研究により、手術前後のペリオスチンの変化を見ることで、バイオマーカーとしての有用性が向上することが示唆され、鼻副鼻腔由来のペリオスチンを特異性が高く測定できることが重要であると考えられた。慢性副鼻腔炎鼻茸におけるペリオスチンアイソフォームは、副鼻腔炎の重症度にかかわらず、全症例でisoform 5が最も強く発現しており、鼻副鼻腔組織での組織特異性があると考えられる。血清中のペリオスチンisoform 5を測定することで、より有用性の高い好酸球性副鼻腔炎のバイオマーカーとして使用できる可能性が考えられる。
