Abstract
Description
実施例1.遺伝的に操作された培養補助細胞(feeder cell)の製造
膜結合性インターロイキン-18(mbIL-18)、膜結合性インターロイキン-21(mbIL-21)及びOX40を発現する培養補助細胞を製造した。具体的には、ヒト由来mbIL18遺伝子(配列番号1)及びmbIL21遺伝子(配列番号2)を、レンチウイルスベクターであるpCDH-CMV-RFPにクローニングし、組み換えレンチウイルス生産用ベクターを作製した。その後、ウイルス生産のために、前記作製された組み換え遺伝子(pCDH-CMV-RFP-mbIL-1821)を、293FT細胞にパッケージングベクターと共に、Lipofectamin3000(Invitrogen)を利用して形質注入させた。時間が経た後、新たな培地に交換し、48時間細胞を培養した後、ウイルスが含有された培地を回収した。回収された培地は、500×gで10分間遠心分離し、0.45μmフィルタを利用し、ウイルスが含有された純粋な培地のみを分離し、mbIL18-mbIL21発現レンチウイルスを生産した。その後、下記比較例1のK562-OX40L細胞を含む培地9mlに、mbIL18-mbIL21発現レンチウイルス1mlを溶かし、ポリブレン(polybrene)(8μg/ml)と共に添加し、48時間細胞培養を進めた。次に、感染された細胞だけ選別するために、超高速流細胞自動分離器を利用し、緑色蛍光及び赤色蛍光をいずれも発現する細胞だけ選別し、mbIL18-mbIL21の発現いかんを、流細胞分析器(FACS)を介して分析し、mbIL18-mbIL21が発現されたK562細胞株(以下、「K562-OX40L-mbIL18-mbIL21」ともする)を生産した。
比較例1.遺伝的に操作された培養補助細胞の製造
OX40Lを発現する培養補助細胞を製造した。具体的には、ヒト由来OX40L遺伝子(配列番号3)を、レンチウイルスベクターであるpLVX-IRES-ZsGreenにクローニングし、組み換えレンチウイルス生産用ベクターを作製した。その後、ウイルス生産のために、前記組み換え遺伝子(OX40L-pLVX-IRES-ZsGreen)を、293FT細胞にパッケージングベクターと共に、Lipofectamin3000(Invitrogen)を利用して形質注入させた。時間が経た後、新たな培地に交換し、48時間細胞を培養した後、ウイルスが含有された培地を回収した。回収された培地は、500×gで10分間遠心分離し、0.45μmフィルタを利用し、ウイルスが含有された純粋な培地のみを分離し、OX40L発現レンチウイルスを生産した。その後、K562細胞を含む培地(RPMI 1640)9mlに、OX40L発現レンチウイルス1mlを溶かし、ポリブレン(8μg/ml)と共に添加し、48時間細胞培養を進めた。次に、感染された細胞だけ選別するために、超高速流細胞自動分離器を利用し、緑色蛍光を発現する細胞だけ選別し、OX40Lの発現いかんを、流細胞分析器(FACS)を介して分析し、OX40Lが発現されたK562細胞株(以下、「K562-OX40L」ともする)を生産した。
実験例1.遺伝的に操作された培養補助細胞の細胞特性
一態様による遺伝的に操作された培養補助細胞のmbIL-18発現特性及びmbIL-21発現特性を確認するために、mRNA及び表面タンパク質の発現レベルを確認した。
一態様による、遺伝的に操作された培養補助細胞のNK細胞活性化効能を予測するために、予備実験でとして、K562-OX40L細胞のサイトカインの添加によるNK細胞活性化程度を確認した。
前記実験例2の結果を基に、前記実施例1で製造されたK562-OX40L-mbIL18-mbIL21細胞のNK細胞の活性に及ぼす影響を確認した。
K562-OX40L-mbIL18-mbIL2細胞によって増幅されたNK細胞の表現型特性を確認した。具体的には、前記実験例2において増幅された健常人供与者(HD)由来NK細胞2×105個を、FACSバッファ(FBS 1%含むPBS)で洗浄した後、APC-Cyanine7接合マウス抗ヒトCD3、及びPE-Cyanine7接合抗ヒトCD56のメンブレン抗体で15分間処理した。その後、細胞を得て、それぞれ異なる蛍光接合された抗ヒトCD16,CD69,NKG2D,NKp30,NKp44,NKp46,CD94,CD158a及びCD158bのメンブレン抗体で30分間追加染色した。その後、前記細胞をFACSバッファで洗浄した後、FACS Caliburを利用してデータを獲得し、Kaluzaで分析した。
活性化受容体の発現が増大することによって増幅されたNK細胞の活性化も、増大することになるために、実施例1の培養補助細胞を利用して増幅した健常人供与者(HD)由来NK細胞のサイトカイン放出、及び細胞毒性による免疫調節活性を評価した。
免疫調節活性を評価するために、細胞内IFN-γを測定し、NK細胞の細胞毒性を評価した。具体的には、実施例1の培養補助細胞を利用して増幅した健常人供与者(HD)由来NK細胞2×105個を、brefeldin A(BD Biosciences)及びMonensin(BD Biosciences)の存在下において、96ウェル丸底プレートにおいて、37℃、5% CO2において5時間培養した。その後、細胞を得て、FACSで洗浄した後、抗ヒトCD3及び抗ヒトCD56のメンブレン抗体で20分間染色した。洗浄して固定させて透過させた後、NK細胞を、氷において、PE接合された抗ヒトIFN-γ抗体で30分間追加して染色した。その後、前記細胞を洗浄した後、FACS Calibur流細胞分析器を使用して分析した。
前述の5-1において増幅された健常人供与者(HD)由来NK細胞2×105個、標的細胞(K562、U266、RPMI8226)2×105個、及びPE接合された抗ヒトCD107aを、96ウェル丸底プレート(96 well U bottom plate)において培養した。1時間後、Monensin及びbrefeldin A(BD Biosciences)を追加した後、4時間追加培養した。その後、NK細胞を、抗ヒトCD3及び抗ヒトCD56抗体で染色して得た。
一態様による培養補助細胞によって増幅されたNK細胞の抗体治療剤としての効能を確認するために、細胞毒性を確認した。
前述の本発明の説明は、例示のためのものであり、本発明が属する技術分野の当業者であるならば、本発明の技術的思想や、必須な特徴を変更せずとも、他の具体的な形態に容易に変形が可能であるということを理解することができるであろう。従って、以上で記述された実施例は、全ての面において、例示的なものであり、限定的ではないということが理解されなければならない。
