本発明において「ナノゲル」とは親水性の多糖に、側鎖として疎水性のコレステロールを付加した構造を有する疎水化高分子ゲルナノ粒子をいう。用いるナノゲルは、例えば国際公開第WO00/12564号パンフレット(高純度疎水性基含有多糖類及びその製造方法)に記載の方法で製造することができる。
カチオン性ナノゲル(カチオン性CHP)は100単糖あたりコレステロールが1.4及びエチレンジアミンが18置換されているものを使用した(CHPNH2ナノゲル)。CHP誘導体又はカチオン性プルランを1mg/mlのリン酸緩衝溶液(PBS)に溶かした。CHPNH2ナノゲルに15分間のソニケーションを行った後、フィルター(0.22 mm)に通した。
実施例1で作製したカチオン性ナノゲル粘膜ワクチン又は抗原単独を、6〜8週齢のBalb/cマウス(雌)に1匹あたりHc 10μg(ナノゲル88.9μg)、TT 30μg(ナノゲル80.0μg)、又はgag p24 10μg(ナノゲル 166.7μg)を、週1回(計3回)鼻腔内に投与することで、経鼻免疫を行った。投与抗原量(液量)はすべての実験区において15μlになるように調整し、片鼻当たり7.5μlを投与した。この際、コントロールとしてPBSを投与した。
実施例1で作製したボツリヌス毒素の重鎖C末端無毒領域(Hc、分子量45000)を抗原とするカチオン性ナノゲルワクチン又はHc単独を実施例2と同様の方法でそれぞれマウス5匹に経鼻免疫した。陰性コントロールとしてPBSを投与した。3回の免疫後、腹腔投与致死量の25000倍(500ng)のボツリヌス毒素(大阪府立大学生命環境科学研究科獣医学専攻、小崎俊司教授により入手した)を腹腔内投与することで、その生存効果を解析した。また、鼻腔組織中に誘導されたHc特異的IgAの中和効果を解析する目的で、10μgのボツリヌスプロジェニター毒素(和光純薬より入手した)を経鼻投与し、その後の生存効果も解析した。
実施例1で作製したボツリヌス毒素の重鎖C末端無毒領域(Hc、分子量45000)を抗原とするカチオン性ナノゲルワクチン又は、同一抗原を同量複合化させたカチオン性リポソーム(Pro-ject)を実施例2と同様の方法でそれぞれマウス5匹に経鼻免疫した。なお、Pro-jectはPIERCEより入手した。
図11に示すように、Hcをカチオン性ナノゲルとの複合体として投与した場合に、Hcをカチオン性リポソームとの複合体で投与した場合に比べ、ボツリヌス毒素に対するトータルIgG抗体価が著しく高かった。
図12に示すように、Hcをカチオン性ナノゲルとの複合体として投与した場合に、Hcをカチオン性リポソームとの複合体で投与した場合に比べ、ボツリヌス毒素に対するトータルIgA抗体価が著しく高かった。
ボツリヌス毒素の重鎖C末端無毒領域(Hc、分子量45000)にDTPA anhydrideを用いて111In(インジウム)を公知の方法で標識した。標識効率は、728.3233±115.3543 CPM/ngであった。その後、標識Hcをナノゲルに複合化させた。1,000,000 CPM量の標識Hcを複合化させたナノゲル粘膜ワクチン又は標識Hc単独をマウスに経鼻投与した。その後の体内動態(脳、嗅球、鼻腔、鼻腔関連リンパ組織(NALT)、頸部リンパ節及び脾臓)をガンマカウンターで追跡評価した。具体的には、経鼻投与の0.17、1、6、12、24及び48時間後に、マウスから脳、嗅球、鼻腔、鼻腔関連リンパ組織(NALT)、頸部リンパ節及び脾臓を採取し、試料重量を測定後、試料からのガンマ線をガンマカウンターで測定した。
