| Outline of Final Research Achievements |
Although there have been several reports that simultaneously stimulated natural killer cells (NK cells) with IL-12, 15, and 18, the cytotoxicity of NK cells by individual cytokine stimulation was unknown. This study demonstrated in more detail that NK cells show increased cytotoxic activity by IL-15 and 18 stimulation and decreased by IL-12. In the clinical research on inflammatory diseases, we proposed scoring systems that can predict the postoperative course from the pre- and intra-operative findings of chronic rhinosinusitis, and the usefulness were discussed.

| Academic Significance and Societal Importance of the Research Achievements |
悪性腫瘍に対する免疫治療において、natural killer細胞（NK細胞）は重要な役割をもつことが報告されている。サイトカインによる刺激を受けたNK細胞のphenotypeの詳細な機能や分化条件について解明した。炎症疾患における研究では、慢性副鼻腔炎の術前、術中所見から、術後経過を推測しうる因子を解明できた。
