(方法)
血圧測定はテイル・カフ法で行った。一回一個体あたり、5~15回測定し、その平均値を使用した。
(結果)
HBc ISS(+)群(コントロール)では、SHRラットの血圧が上昇した。一方、HBc-AngII ISS(+)群では、明らかな血圧低下を示した(図1)。
(試薬および測定機器)
・Angiotensin II-BSA conjugate, Angiotensin I-BSA conjugate: DSS (Disuccinimidyl suberate)をスペーサーとして作成
・Angiotensinogen (Human) : sigma A2562
・Nunc Maxisorp(Cat.442404)
・3% skim milk (PBS希釈)
・PBS-T(0.05% Tween)
・2次抗体:HRP-conjugated anti-mouse IgG secondary antibody (GE, NA931V), HRP-conjugated anti-rat IgG secondary antibody (GE, NA935V)
・TMB溶液:sigma T0440

・マイクロプレートリーダー (InterMed, ImmunoMini NJ-2300)
(方法)
10μg/ml の濃度でAngiotensin II-BSA、Angiotensin I-BSA, Angiotensinogenを96 well plateにそれぞれ50μlずつ添加し、4℃で終夜インキュベートした。その後、ウェルの内容物を捨て、3% skim milk(150μl/well)を加え、2時間、室温にてインキュベートすることによりブロッキングした。
ウェル内の内容物を捨て、3% skim milkで希釈したマウス血清を50μlずつ添加し、4℃にて終夜インキュベートした。
各ウェルをPBS-Tで5回洗浄した。3% skim milk で1/1000倍に希釈したHRP-conjugated anti-mouse IgG secondary antibody又はHRP-conjugated anti-rat IgG secondary antibody(50μll/well)を添加し、3時間、室温にてインキュベートした。ウェル内の内容物を捨て、各ウェルをPBS-Tで3回洗浄した。TMB溶液(50μl/well)を添加し、30分間、室温にてインキュベートした。0.5N H2SO4(50μl/well)の添加により反応を停止し、450nmで吸光度を測定した。
ワクチン投与前には認められなかったBSA-AngIIに対する抗体価が、計3回のワクチン投与(0週および2、4週)により上昇した。抗体価は、3回投与後の8週の時点で最も上昇しており、16週も減少傾向ながら維持された(図2)。またHBc-AngIIワクチン投与によって、BSA-AngIに対する抗体価よりもBSA-AngIIに対する抗体価のほうがより強く上昇した(図3)。
以上、血圧測定および抗体価測定の結果から、HBc-AngII ISS(+)DNAワクチン投与により、AngIIに対する抗体価を上昇させ、高血圧症を予防又は治療し得ることが示された。
1.動物実験
実施例1と同様に、10週齢高血圧ラット(SHR)背部皮膚にシマジェット(商品名、島津製作所)を用いて2週間ごとに、各ベクターを3回投与した(100μg/μl×2カ所/回)。
HBc-AngII ISS(+)群:6匹
HBc ISS(+)群:4匹
生理食塩水群:5匹
0週、2週、4週に投与し、投与開始から0週、4週間、8週間、12週間、16週間、20週間及び24週間後に血圧測定、血清採取および抗体価測定を行った。
(方法)
実施例1と同様に、血圧測定はテイル・カフ法で行った。一回一個体あたり、5~15回測定し、その平均値を使用した。
(結果)
HBc ISS(+)群(コントロール)及び生理食塩水群では、SHRラットの血圧が上昇した。一方、HBc-AngII ISS(+)群では、明らかな血圧低下を示した(図4)。この血圧低下効果は、投与開始から24週後まで持続した。

以上より、HBc-AngII ISS(+)DNAワクチン投与により、AngIIに対する抗体価を上昇させ、高血圧症を予防又は治療し得ることが示された。
