各外来ポリペプチドをコードするcDNAコンストラクトの発現プラスミド(pcDNA3.1+)を、HEK293T細胞にTransfectionし、48時間後の培養上清を回収し、Amicon-Ultra30Kで限外ろ過して濃縮した後、spikeタンパク質としての発現量、及びACE2結合タンパク質としての発現量を求めた。前者はSpike RBD*検出ELISA(anti-spikeRBD抗体を固相化、 anti-spikeRBD抗体で検出)で、後者はACE2結合検出ELISA(ACE2を固相化、anti-spikeRBD抗体で検出)で測定した。値は濃縮液中の濃度として算出した。(*Receptor binding domain)
各ウイルスをVero細胞にMOI 0.01で感染し、48時間後の培養上清を回収し、Amicon-Ultra30Kで限外ろ過して濃縮した後、spikeタンパク質としての発現量、及びACE2結合タンパク質としての発現量を求めた。前者はSpike RBD検出ELISA(anti-spikeRBD抗体を固相化、 anti-spikeRBD抗体で検出)で、後者はACE2結合検出ELISA(ACE2を固相化、anti-spikeRBD抗体で検出)で測定した。値は濃縮液中の濃度として算出した。
各ウイルスを1x107 pfuあるいは1x106 pfu*/100μlで準備し、6週齢のA/Jマウス(雌)の後肢前腿部に27G針にて筋肉内投与(マウス1匹当たり100μlを両脚に分けて投与(1か所50μlずつ))した。4週間(4w)後にもう一度投与した。2, 4, 6, 8週間後に経時的に血清を回収し(下表参照)、抗Cov2-spikeタンパク抗体の発現量をELISA(Cov2-spikeタンパク固相化、HRP標識抗マウスIgG抗体にて検出)にて定量した。(*Benzonaze処理ウイルス。ウイルス製造の際に、回収したウイルスをBenzonaseで酵素処理し、宿主細胞として用いたVero細胞由来のDNAとRNAを除去したもの。)
抗Cov2spikeタンパク抗体の発現量についての結果を図4-1に示す。抗体産生量は、B>A>>C>Dの順であった。Bでは1x107 pfu投与の方が効果が高く、Aでは投与後2wまでは1x107 pfu投与の方が抗体産生量が多かったが、その後は1x106 pfu投与の方が逆転した。A、Bともに、初回投与では2wから4wで減少傾向が見られたが、4wにおけるブースター投与により、6w, 8wと抗体産生量を顕著に増加させた。C, Dでは、5匹中1~2匹が検出される程度で、それ以外は検出限界以下であった。
投与部位の筋肉からゲノムDNAを調製後、ICP6/LacZ probe, primerセットを用いて、リアルタイムPCRを行い、ウイルスゲノムのコピー数を算出した。結果を図6に示す。
8w後の筋肉を採取し、HE染色ならびに、抗HSV-1抗体(緑)、抗CD8抗体(茶色)、抗CD4抗体(赤)を用いてIHCを行った。図7に、代表的な1x107 pfu投与の結果を示すが、1x106 pfuでもほぼ同様の結果であった。抗HSV-1抗体、抗CD4抗体、抗CD8抗体のすべてで染まることはなかった。
図8にマウス個々の体重の経時的変化を示す。A:T-Cov2SPPは、1x106 pfu投与、1x107 pfu投与ともに麻酔の影響で1匹ずつ死亡した。0, 2, 4, 6, 8wはウイルス投与あるいは採血のため、麻酔下で体重測定した。麻酔を打たない場合の方が体重が低い印象であった。観察期間中、行動・毛並みに異常はなかった。歩き方が変なマウスもいなかった。
B:T-Cov2SPPFウイルスを、1x106 pfuあるいは1x107 pfu/100μlで準備し、 6週齢のA/Jマウス(雌)の後肢の前腿部に筋肉内投与(マウス1匹当たり100μlを両脚に分けて投与)した。6、12、18日後に経時的に血清を回収し、抗Cov2-spikeタンパク抗体の発現量をELISA(Cov2-spikeタンパク固相化、HRP標識抗マウスIgG抗体にて検出)にて定量した。
各ウイルスを1x107 pfu/100μlで準備し、6週齢あるいは19週齢のA/Jマウス(雌)の後肢の前腿部に筋肉内投与(マウス1匹当たり100μlを両脚に分けて投与)した。0,1,2,3日後に筋肉及び血清を回収し、Cov2-spikeタンパクの発現量(血中及び筋肉中)をELISAにて定量(anti-spikeRBD抗体を固相化、 HRP標識抗spikeRBD抗体で検出)し、さらにリアルタイムPCRにて筋肉中ウイルス量を定量した。ウイルスとしては、A:T-Cov2SPP、T-01及びmockを用いた。Aを用いたのは、A-Dで一番発現量が高かったためである。
結果を図10-1に示す。筋肉内では発現が認められる。若齢マウス(6週齢)の方が老齢マウス(19週齢)に比べてその発現量が高いことが分かった。投与一日目が発現のピークであり、時間経過とともにその発現量は低下する。
結果を下表及び図10-2に示す。投与直後から経時的にウイルスDNA量の減少が認められた。若齢マウス(6週齢)の方が老齢マウス(19週齢)に比べてd1(7倍),d2(1.4倍)ともに保持される量が高い傾向にあった。T-01 d1でAに比べてウイルス量が少し多めなのは、投与後確認した力価(actual titer)が高かったため。
B:T-Cov2SPPFウイルスを1x106 pfuあるいは1x107 pfu/100μlで準備し、 6週齢あるいは17週齢のA/Jマウス(雌)の後肢の前腿部に筋肉内投与(マウス1匹当たり100μlを両脚に分けて投与)した。1,4日後に筋肉及び全血を回収し、リアルタイムPCRにて血中及び筋肉中ウイルス量を定量した。(Bを用いたのは、一番抗体産生量が高いため)
すべてのサンプルで検出されなかった。
結果を下表及び図11に示す。投与部位の筋肉中のウイルス量は、経時的に減少した。若齢マウス(6週齢)の方が老齢マウス(17週齢)に比べてd4で30倍ほど保持される量が高い傾向にあった。
各ウイルスを1x107 pfuあるいは1x106 pfu/100μlで準備し、7週齢のA/Jマウス(雌)の後肢の前腿部に筋肉内投与(マウス1匹当たり50μlを両脚に分けて投与)した。0,1,5日後に筋肉を採取し、HE染色ならびに、抗HSV-1抗体(緑)、抗CD8抗体(茶色)、抗CD4抗体(赤)を用いてIHCを行った。ウイルスとしては、A:T-Cov2SPP、T-01及びmockを用いた。
B:T-Cov2SPPFウイルスを1x106pfu/100μlで準備し、7~8週齢のDBA/2マウス(雌)の後肢の前腿部に筋肉内投与(マウス1匹当たり100μlを両脚に分けて投与)し、下記の測定を行った。
2) 1, 2, 3, 4週後に血清を回収し、抗Cov2-spikeタンパク抗体の発現量をELISA(Cov2-spikeタンパク固相化、HRP標識抗マウスIgG抗体にて検出)にて定量した。
B:T-Cov2SPPFウイルスを筋肉内投与すると、筋肉内にはウイルスDNAが4週後でも痕跡程度に検出されるのみであった(図13-1、下表)。
