Outline of Research at the Start

ビフィズス菌による抗体などのバイオ医薬産生は、持続的医薬の腫瘍内産生が可能となり、副作用が軽減され、かつ高価な抗体医薬などによる医療経済問題解決の一助となる。現在までにヒトでの臨床試験が行われ、現象的には安全性が認められるものの、その分子基盤をより解明し、より生体内で安定性のある理想的生物製剤へと改善を目指す。

Outline of Final Research Achievements

We investigated the immune response of Bifidobacteria (B) used in DDS. Immune cell activation was evaluated using mouse BMDC (cultured with bovine serum). Bacterium B induced IL-6 and IL-12p40 in a TLR2-dependent manner, but the levels were extremely low compared to Staphylococcus aureus and E. coli, and the induction ability was further weakened in the presence of host serum. When B bacteria was administered intravenously to tumor-bearing mice, the amount of cytokines in the blood was the same as that of the control group, the number and proportion of various cells remained unchanged, and there was no systemic inflammation. From the above,the immunological safety of bacterium B was suggested, not meaning that it never induces an immune reaction at all. In the future, we would like to aim for a more reliable and immunologically safe DDS tool by chemically modifying the surface of B bacteria and creating genetically modified B bacteria.

Academic Significance and Societal Importance of the Research Achievements

がん治療においては、抗体医薬を始めとする様々な分子標的薬の開発がなされ、飛躍的進歩を遂げている。しかし、従来と質の異なる副作用、がんの不均一性による耐性細胞の出現、高薬価などに対する対応策が必要である。これらの問題点を解決するために、がんの嫌気的環境に着目しビフィズス菌を用いて制がん剤を腫瘍局所で持続的産生する系を樹立し、前臨床試験を経て第1相臨床試験まで進んだ。現在までの結果からは、安全性が示唆されるが、その詳細な理由は未解明であり、感染免疫学的に興味深い。安全性をさらに担保するためには免疫的解析が重要であるが、本研究による分子免疫学的安全性の裏付けの進展は免疫学的、社会的に意義深いと思う。
