他に規定がない限り、本明細書に用いられる技術的および科学的用語は、本発明が属する分野の当業者によって一般的に理解されているのと同じ意味をもつ。
本発明の一実施形態において、CD3ζおよびCD137シグナル伝達ドメイン、ならびにデキストランなどの外因性抗原に特異的な抗原結合ドメインを含むCARを発現するTregが作製される。CARをコードするDNA構築物は、当技術分野において周知の方法(例えば、ウイルスに基づいた系、物理的方法、生物学的方法、化学的方法)により、Treg細胞へトランスフェクションまたは形質導入することができる。Treg細胞においてCARをコードする核酸を組み込み、好ましくは安定的に組み込むために用いられる方法に関わらず、結果として、そのTreg細胞はCARを発現する。これらのTreg細胞は、インビトロおよびインビボにおいて、細胞培養中である細胞、またはそれらが適用された対象の血液中に循環している細胞へのデキストランの添加により、活性化することができる。
CAR構築物は、外因性抗原(例えば、デキストラン)に特異的な抗体に由来する特異的結合断片を含有する。ヒンジ領域は、IgGドメイン、CD8a CD8a、またはCD28に由来し得、CARの検出を可能にするエピトープ/タグを含み得る。例えば、図1Aに示されているように、膜貫通ドメインは、例えば、CD8aまたはCD28に由来し得、その後、CD3ζおよびCD137を含有する1〜3つのシグナル伝達ドメインが続く。Tregは、CD137−CD3ζ−CARを発現するように遺伝子操作され、それは、LNGFRの発現により決定することができる(図1B)。CD137−CD3ζ−CARの抗原結合は、図1Cにデキストランについて示されているように、(例えば、蛍光で)標識され得るそれぞれの抗原とのインキュベーションにより決定することができる。
外因性抗原(例えば、デキストラン)に特異的であるCAR−Tregは、それらのそれぞれの抗原により活性化することができ、活性化は、CD137発現により分析することができる。ビーズ結合型デキストランでの刺激後のCAR−Treg活性化は、図2Aに示されている。CD137−CD3ζ−CARは、CAR−TregにおいてCD137発現を誘導するのに、より強力であった(図2A)。同じ特異性をもつ他の試験されたCAR構築物の機能性を、ZAP70のリン酸化により分析した。リン酸化されたZAP70は、例えば、CD28−CD3ζシグナル伝達を有するCAR−Tregにおいて検出されたが(図2B)、CD137−CD3ζ−CARだけが、Treg活性化を誘導した(図2A)。
外因性抗原(例えば、デキストラン)に特異的であるCAR−Tregは、抗CD3/CD28(図3A、C)またはそれらのそれぞれの抗原、例えば、ビーズ結合型デキストラン(図3B、D)の存在下で増殖することができる。CD137−CD3ζ−CARを有するCAR−Tregだけが増殖し、CD137−CD3ζ−CARのより優れた機能性を示した。
CD3ζと組み合わせての異なる共刺激ドメインを有する抗デキストランCARを発現するCAR−TregおよびCAR−Tconを、作製した。デキストラン結合性は、構築物間で類似していたが(図4A)、異なるシグナル伝達ドメインは、Treg活性化およびTcon活性化の異なる影響を生じた。Treg活性化を、CD137発現により分析し、Tcon活性化をCD154発現により分析した。CAR−TregはCD137−CD3ζに関して、CAR−TconはCD28−CD3ζに関して、最も効率的に活性化された(図4B)。
CD137−CD3ζ CARを有するCAR−Tregを、6時間のデキストランでの刺激後、LNGFR発現またはCD137発現により単離した。導入遺伝子(図5A)および受容体発現(図5B)は、どちらのソーティング戦略の間でも類似していたが、抗原特異的再刺激は、CAR−TregがCD137発現によりソートされたときに、非常に効率的であった(図5C)。
CAR構築物
全てのCAR構築物は、AC146由来scFv、CD8膜貫通ドメイン、XS IgG4ヒンジ、ならびにトランスフェクションおよび形質導入された細胞の検出のためのP2A連結ΔLNGFRを含有した。レンチウイルス上清を、HEK293T細胞の発現ベクターおよびパッケージングプラスミドでの同時トランスフェクションにより作製した。トランスフェクションの1日前、3×106個のHEK293T細胞を、10cm細胞培養ディッシュにおける、DMEM(Gibco(登録商標))+10%FCS+100U/mlペニシリン、100μg/mlストレプトマイシン+50μM 2−メルカプトエタノールからなる完全DMEM(cDMEM)(全て、Thermo Fisher Scientific、Schwerte、Germany)に播種した。細胞に、2.5M CaCl2を追加したddH2O中に希釈された、0.84μg pMDG−2.VSV−G、5.16μg pCMVΔR8.74、および3.35μgデキストラン−CARプラスミドを一過性にトランスフェクションした。通気しながら、2mlの2×HBSバッファー(ddH2O中、136.89mM NaCl、4.96mM KCl、1.76mM Na2HPO4、20.98mM HEPES、pH=6.75〜6.76)をその溶液にゆっくり加え、そのトランスフェクション溶液の2mlを、細胞へ滴下した。そのトランスフェクション溶液を含有する培地を、4時間後、除去し、細胞を、予熱されたPBSで2回、洗浄し、その後、新鮮なcDMEMを加えた。48時間後、レンチウイルス上清を採取し、濾過し(0.45μm)、すぐに用い、または最長6ヶ月間、−80℃で保存した。
健康なドナー由来の白血球アフェレーシス生成物を、Charite University hospital、Berlin、Germanyから、倫理指針に従ってインフォームドコンセントと共に入手した。PBMCを、Ficoll−Paque(GE Healthcare Life Sciences、Freiburg、Germany)勾配遠心分離により取得した。CD25+ Tregを、PBMCから、CD25マイクロビーズ(Miltenyi Biotec、Bergisch Gladbach、Germany)を用いて、製造会社の推奨に従って単離した。Tregを、TexMACS培地(Miltenyi Biotec、Bergisch Gladbach、Germany)+5%(v/v)ヒトAB血清(Sigma−Aldrich、Schnelldorf、Germany)+100U/ml IL−2+100nmolラパマイシン(どちらもMiltenyi Biotec、Bergisch Gladbach、Germany)および100U/mlペニシリン/100μg/mlストレプトマイシン(Gibco(登録商標)、Thermo Fisher Scientific、Schwerte、Germany)からなる「Treg増殖培地」中、4:1のビーズ対細胞比でのTreg増殖ビーズ(Miltenyi Biotec、Bergisch Gladbach、Germany)の存在下で培養した。CD4+ Tconを、TexMACS培地(Miltenyi Biotec、Bergisch Gladbach、Germany)+5%(v/v)ヒトAB血清(Sigma−Aldrich、Schnelldorf、Germany)+200U/ml IL−2において、30ng/ml抗CD3および1μg/ml抗CD28の存在下で活性化した。3日目、培地を、4μg/ml硫酸プロタミンを追加したそれぞれのレンチウイルス上清と置き換え、細胞を、レトロネクチンコーティング化96ウェルプレートにおいて、800g、32℃で90分間、遠心接種を行った(spinoculate)。遠心分離後、ウイルス上清を除去し、新鮮な培地を細胞に加えた。形質導入効率を、形質導入後2日目または3日目に、細胞表面上のLNGFRの染色により評価した。TregおよびTconを10〜12日間、増殖させ、培地を2〜3日ごとに交換した。細胞は、Treg増殖ビーズ(4:1 ビーズ対細胞比、Miltenyi Biotec、Bergisch Gladbach、Germany)、可溶性FITCデキストラン(MW:2,000,000、2μg/ml、Sigma−Aldrich、Schnelldorf、Germany)、ビーズ結合型デキストラン(1:100;PBS中デキストランコーティング化マイクロビーズ、Miltenyi Biotec、Bergisch Gladbach、Germany)、または10ng/ml PMAおよび500ng/mlイオノマイシン(Sigma−Aldrich、Schnelldorf、Germany)での6時間の再刺激前に、RPMI−1640(Gibco(登録商標)、Thermo Fisher Scientific、Schwerte、Germany)+5%(v/v)ヒトAB血清(Sigma−Aldrich、Schnelldorf、Germany)+100U/mlペニシリン/100μg/mlストレプトマイシン(Gibco(登録商標)、Thermo Fisher Scientific、Schwerte、Germany)中、刺激無しで2日間、休ませた。
