Research Abstract

結核菌に対するワクチンとしては生菌ワクチンであるBCGが用いられているが、その成人肺結核に対する防御効果は否定的であり、より有効なワクチンの開発が急務となっている。これまで我々は、MPT51をはじめとして、いくつかの結核防御抗原のT細胞エピトープを同定してきた。これらを用いた成分ワクチンにより、結核菌に対する免疫応答を効率よく誘導するためには、アジュバントや抗原デリバリーシステムの開発が必須事項である。本研究は我々が新規開発したオリゴマンノース被覆リポソーム(OML)に、結核菌防御抗原を封入してマウスへ種々の条件で接種し、その免疫誘導効果を指標として結核菌抗原を標的とした効率の良い抗原デリバリーシステムを構築することを目的としている。
本年度はまず実験系を確立する目的で、卵白アルブミン(OVA)を仮想抗原としてOMLに封入してマウスに免疫し、IFN-γ産生を指標にして免疫応答を解析した。その結果OVAをOMLに封入してマウスに免疫すると、OVA単独免疫に比べ、抗原特異的なCD4陽性およびCD8陽性T細胞が、より効率的に誘導できることが明らかになった。加えて、大腸菌で大量発現させた結核防御抗原MPT51をOMLに封入してマウスに免疫し、産生されるMPT51特異的な抗体のサブクラスを検討したところ、一部のマウスでIgG2a/IgG2cの抗体価の上昇が確認できた。
これらの結果から、OMLを免疫に用いる事で、結核に対する免疫で重要とされるTh1型の免疫応答を効率よく誘導できることが示唆された。
