Abstract
Description
ホスファチジルセリン(PS)は、アポトーシス細胞、アポトーシスブレブ(bleb)、エクソソーム、ストレス腫瘍細胞および腫瘍血管系の表面において表出される(externalized)陰イオン性リン脂質であるが、腫瘍微小環境においては免疫抑制性の分子である(Birge et al. Cell Death and Differentiation 2016 23:962-978)。低酸素および他の代謝性ストレス、アポトーシス細胞の高いアポトーシス指標、ならびに、腫瘍由来エクソソームの放出による、腫瘍微小環境におけるPSの上方制御は、実質的に全ての固形癌で観察されている(He et al. Clin. Cancer Res. 2009 15: 6871-6880)。上方制御されたPSは、次に、腫瘍細胞上および浸潤性の骨髄由来食細胞上の、過剰発現したTyro3、AxlおよびMer(TAM)受容体と相互作用する。PS/PS受容体の会合は、集合的にPS依存性エフェロサイトーシスおよび、IL−10およびTGF−βなどの免疫抑制性サイトカインの産生を引き起こす。(Huynh et al. J. Clin. Invest. 2002 109:41-50; Rothlin et al. Cell 2007 131: 1124-1136)。
第二世代または次世代の免疫生物学的製剤として、より有効なPS標的化誘導体を開発する必要がある。
本発明の側面は、サイトカインと、融合分子をホスファチジルセリン(PS)に対して標的化するポリペプチドとを含む、融合分子に関する。
一つの非限定的な態様において、融合分子のポリペプチドは、本明細書においてTAMリガンドとも称される、Tyro3、AxlおよびMer受容体のPS結合リガンドを含む。
一つの非限定的な態様において、融合分子のサイトカインは、免疫刺激性サイトカインである。
別の非限定的な態様において、融合分子のサイトカインは、免疫抑制性サイトカインである。
本発明の別の側面は、本発明の融合分子または本発明の融合分子を含む医薬組成物を投与することにより、対象の病変部位に対してサイトカインを標的化する方法に関する。
本発明の別の側面は、サイトカインを、本発明の融合分子または本発明の融合分子を含む医薬組成物を介して投与することにより、サイトカインの全身作用を最小化する方法に関する。
一つの非限定的な態様において、本発明により処置される疾患、障害または症状は、癌、感染または炎症性の症状もしくは障害である。
免疫システムは、腫瘍細胞などの病原性細胞、ウイルスおよび炎症性疾患に関与する炎症細胞を除去する潜在的能力を有する一方で、有効な免疫療法にとっての主要な障壁は、臨床的に有意義な応答を誘発する能力である。そのために、宿主は、有効な免疫応答の進展を限定する、内在性の抑制性メカニズムを克服できなければならない。

以下の非限定的な例は、本発明をさらに説明するために提供される。
例1:融合分子の合成方法
生物学的評価のために融合分子を作製するため、インタクト(intact)未修飾GAS6、IFN−λ2、IFN−β、および融合IFN分子であるIFN−β−IFN−λ2(コントロール)、および6個のGAS6−IFN融合分子であるGas6(Gla)−IFN−λ2、Gas6(Gla)−IFN−β、Gas6(Gla)−IFN−β−IFN−λ2、Gas6(Gla+EGF)−IFN−λ2、Gas6(Gla+EGF)−IFN−βおよびGas6(Gla+EGF)−IFN−β−IFN−λ2を発現する哺乳類動物プラスミドを、HEK293T細胞に一過性にトランスフェクションした。融合分子のHisタグを付したバージョンおよびリン酸化可能バージョンを発現するプラスミドもまた、製作してHEK293細胞にトランスフェクションした。分泌されたインタクトタンパク質または融合タンパク質を含有する条件培地を、トランスフェクションの48時間後に回収した。
様々なインタクトGas6およびIFN分子、ならびにGas6(Gla)、またはGas6(Gla+EGF)IFN融合分子を含有する条件培地を、SDS−PAGEにより分離して、膜に転写し、γカルボキシル化およびHisタグ特異的な抗体を用いたイムノブロッティングによりγカルボキシル化を評価した。
Gas6(Gla)、またはGas6(Gla+EGF)IFN融合タンパク質の活性を、IFN−λR−γR1レポーター細胞株を処置することにより評価した。レポーター細胞を、コントロールとして用いられた組み換えIFN−λ2、または、アポトーシス細胞ありもしくはなしでGas6(Gla)およびGas6(Gla+EGF)IFN融合分子を含有するHEK293T細胞上清により、30分間処置した。細胞溶解物を調製し、IFN−λ受容体活性化の出力としてのチロシンリン酸化Stat1(pStat1)に特異的な抗体によるイムノブロッティングにより、Stat1リン酸化を測定した。pStat1イムノブロットは、融合分子によるIFN−λ受容体の活性化の、ホスファチジルセリン結合依存的な増大を示した。さらに、アポトーシス細胞のγカルボキシル化Gas6−IFN融合分子への結合は、IFN活性のアポトーシス細胞との共沈により示された。
同数のヒト網膜色素上皮ARPE19細胞またはマウス腸上皮細胞(mIEC)を、96穴マイクロタイタープレートの全穴において、10%FCS含有DMEM培地中に播種し、300ng/ml〜0.002ng/mlの範囲の様々な濃度で組み換えIFN−λ2により、あるいは、Gas6(Gla)−IFN−λ2およびGas6(Gla+EGF)−IFN−λ2融合分子、またはIFN−β−IFN−λ2およびGas6(Gla+EGF)−IFN−β−IFN−λ2をそれぞれ含有するHEK293T細胞上清の3倍系列希釈物により、処置した。前処置の24時間後、細胞に、0.1pfu/細胞の濃度で穴に添加された水疱性口炎ウイルス(VSV)を負荷し、細胞をさらに24時間インキュベートして、融合分子の抗ウイルス活性を分析した。細胞生存能を、製造者のプロトコール(Millipore / Sigma)にしたがってMTTアッセイを用いて測定した。
免疫コンピテントな同系の6〜8週齢C57BL/6マウス(Jackson Laboratory)に、105個の、EO771モック細胞(空ベクターをトランスフェクションしたEO771細胞) IFN−β−IFN−λ2 Gas6(Gla+EGF)−IFN−β、Gas6(Gla+EGF)−IFN−λ2またはGas6(Gla+EGF)−IFN−β−IFN−λ2融合分子を分泌する細胞(様々な融合分子を発現するベクターをトランスフェクションしたEO771細胞)を、乳房脂肪体に注射した。マウスを、1〜2日おきに注射部位の触診により腫瘍増殖を確認し、腫瘍体積(V)を、クリッパー(clipper)を用いて腫瘍の長さ(L)および幅(W)を測定し、次いで式V=(LxWxW)/2に適用することにより、計算した。
本発明の融合分子が腫瘍微小環境へ動員され、腫瘍微小環境中に局在する能力を保持しているかどうかを調べるため、融合分子が腫瘍部位へ特異的に送達され得るかどうかを決定するための評価を行った。これらの研究には、Pulverer, J.E. et al. (Journal of Virology 2010 84:8626-8638)により記載されている、ルシフェラーゼの発現がIFN誘導性Mx2プロモーターにより制御されている、Mx2ルシフェラーゼレポータートランスジェニック(TG)マウスが用いられる。これらのレポーターマウスは、I型またはIII型IFNのいずれかを静脈内注射した場合に、組織特異的にルシフェラーゼを発現する:I型IFNは、主に肝臓においてルシフェラーゼ発現を誘導するのに対し、III型IFNは胃腸管においてルシフェラーゼ発現を引き起こす(McElrath, C. et al. Cytokine 2016 87:141-141)。
均一に精製した後、リン酸化可能なIFN融合分子を、in vitroで放射性標識し、尾静脈もしくはSQ注射により、担癌(tumor-bearing)マウスおよび呼吸器インフルエンザAウイルスもしくは胃腸ロタウイルスのいずれかに感染したマウスに注射し、標識タンパク質のin vivo分布を、X線画像化および様々な解剖組織における放射活性分布を測定することにより、モニターした。
本発明の融合分子の腫瘍微小環境を変化させる特性を、2種の独立した、遺伝的に受容可能な、乳癌増殖の同所性移植モデルにおいて比較する。これらのモデルには、(BALB/cマウス系統には)4T1細胞モデルおよび(C57BL/6マウス系統には)E0771細胞モデルが含まれる。両方のモデルは、低い免疫原性の潜在的能力および肺への自然転移を含むヒト乳癌の側面を再現する、悪性のトリプルネガティブ(triple negative)腫瘍乳癌モデルを反映する。さらに、4T1およびE0771細胞の両方は、3種の全てのTAMを発現すると考えられており、これらの癌モデルを、PS受容体を発現する腫瘍を研究するのに適したものにしている。様々なインタクトまたはGas6融合IFN分子を構成的に発現する4T1およびE0771細胞を作製した。同等のレベルのIFN分子を発現する細胞集団を選択する。
TMEにおける免疫細胞のサブセット(subset)およびこれらが本発明の融合分子によりどのように変化するかを調べることは、免疫応答を変化させることにおけるそれらの役割のメカニズム的な洞察を与える。融合分子は、宿主の抗腫瘍応答に影響を与える阻害性シグナルを元に戻して、TMEをより免疫競合的な環境へプログラミングし直す(reprogram)であろうと予想される。これらの問題に実験的に取り組むため、NanostringおよびIHCに基づく方法の組み合わせを用いて、TMEにおいておよび腫瘍境界におけるPMN、DC、MPh、NKおよびT細胞の細胞頻度をプローブする。
上記モデルにおいて、抗癌治療剤として、最も強力な抗腫瘍的有効性を示す融合分子をさらに試験する。これらの実験のために、融合分子を産生し、Hisタグ精製技術を用いて、動物試験に十分な量を、エンドトキシンフリーで精製する。これらの実験のために、元の4T1およびE0771腫瘍を定着させて、約0.3cm3の体積まで増殖させ、動物に、1μgの選択された精製融合分子を、毎日静脈内注射する。有効な腫瘍抑制が達成された場合には、組換えタンパク質の投与について、低い用量および頻度もまた試験する。
PS標的化IFN融合分子の抗ウイルス効力を、A型インフルエンザ感染マウスモデルを用いて試験する。効力は、インタクトIFNと比較する。マウスに1LD50のA型インフルエンザウイルスPR8、WSN、Udorn株または他の株を感染させる8〜24時間前に、予防として、様々な用量で(成体の約20mgの8週齢マウス当たり0.1、0.3、1、3、10μg;PBSをコントロールモック処置として用いる)マウスにSQまたは鼻内(IN)注射する。生存および体重減少を毎日モニターする。
TAMレポーター細胞株(Tyro3/IFN−γR1、Axl/IFN−γR1およびMertk/IFN−γR1)を、過剰に与えられたGas6−IFN融合分子の存在下または非存在下で、インタクトγカルボキシル化Gas6およびPros1により処置する。融合分子が内因性インタクトリガンドによるTAM受容体活性化を遮断する能力を、Stat1活性化(pStat1)の減少を測定することにより評価する。
