Description
本実施形態では、能動学習実験法(特開平11−316754号公報)を用いて得られる仮説により予測された、HLA分子との結合性が、−logKd値に換算して3以上であるアミノ酸配列を含み、8以上11以下のアミノ酸残基からなるペプチドを、HLA結合性ペプチド候補とした。そして結合実験を行った結果、実際にこれらのペプチドがHLA結合性ペプチドであることを確認した。
さらに、上記のHLA結合性ペプチドは、ヒトHLA−A2型分子に結合するペプチドであってもよい。
さらにこの構成によれば、日本人種に加えて欧米人種に多いHLA−A2型分子に対して結合するペプチドが得られるため、日本人種に加えて欧米人種に特に効果的な治療薬、予防薬などの開発に利用できる。
本実施形態によれば、HLA−A型分子に結合するHLA結合性ペプチドであって、上記のHLA結合性ペプチドに含まれるアミノ酸配列のうち1若しくは2個のアミノ酸残基が欠失、置換若しくは付加されてなるアミノ酸配列を含み、8以上11以下のアミノ酸残基からなるHLA結合性ペプチドが提供される。
本実施形態によれば、上記のHLA結合性ペプチドをコードするDNA配列を含むDNA断片が提供される。本実施形態に係るDNA断片は、特定のDNA配列を含むため、上記のHLA結合性ペプチドを発現可能である。
本実施形態によれば、上記のHLA結合性ペプチドをコードするDNA配列を含む組み換えベクターが得られる。本実施形態に係る組み換えベクターは、特定のDNA配列を含むため、上記のHLA結合性ペプチドを発現可能である。
を得た。
実験データは、蓄積データとして随時格納される。
ペプチドは、Fmocアミノ酸を用い、Merrifieldの固相法にて、マニュアル合成をした。脱保護の後、C18カラムを用いて逆相HPLC精製をし、95%以上の純度にした。ペプチドの同定と純度の確認は、MALDI−TOF質量分析にて行った(Voyager DE RP、PerSeptive)。ペプチドの定量は、BSAを標準蛋白質としてMicro BCAアッセイ(Pierce社)にて行った。
HLA−A*2402遺伝子の産物であるHLA−A24型分子へのペプチドの結合能の測定は、HLA−A24型分子を発現するC1R−A24細胞(熊本大学、滝口雅文教授作成のものを、許可を得て愛媛大学、安川正貴助教授から供与いただいた。)を用いて行った。
HLA−A*0201遺伝子の産物であるHLA−A2型分子へのペプチドの結合能の測定は、HLA−A*0201を発現する細胞株JYを用いて行った。
結合能を測定したいペプチドの段階希釈列に上記JY細胞と精製β2mを加えたのち、氷上で4時間インキュベートした。この時点までに再会合したHLA−A*0201分子を、会合型特異的な蛍光標識モノクローナル抗体BB7.2を用いて染色した。
その結果、上記表1〜表4に示した予測結果および実験結果が得られた。
