Outline of Final Research Achievements

It is expected that regulation of the recognition response of innate immunity will control inflammatory response and induce adaptive immunity, thereby treating and preventing diseases. In this study, we clarified that some antimicrobial peptides may enhance the innate immune recognition response by unmethylated CpG DNA, which is a microbial component, by experiments using mouse macrophage-like cultured cell lines. In addition, studies using human macrophage-like cultured cell lines revealed that phagocytosis of microparticles enhances inflammatory response including lipopolysaccharide.

Academic Significance and Societal Importance of the Research Achievements

自然免疫の認識応答は獲得免疫の誘導に必要である。従ってその調節によりワクチンの有効性を高めるなどの疾病の予防がなされることが期待できる。本研究は抗菌ペプチドをワクチンのアジュバントとして利用する可能性を示す点で初回的意義が大きい。また、微粒子が炎症応答を増悪することが示唆されている。本研究では微粒子の貪食に炎症応答増強作用があることを示した。炎症の制御にとって重要な知見である。
