Abstract
Description
本発明は、生物学的活性を有する合成組成物および半合成組成物、ならびに哺乳動物患者における種々の障害の処置および/または予防におけるそれらの使用に関する。より詳細には、本発明は、患者の体内に導入された後、有益な抗炎症性の、器官保護効果および免疫調節効果を生じる合成体および半合成体の調製および使用に関する。本発明はまた、炎症性疾患および自己免疫疾患ならびにそれらの徴候を緩和するための処置および組成物に関する。
樹状細胞(DC)およびマクロファージ(Mph)を含む、専門的な抗原提示細胞(APC)は、抗原(Ag)を能動的に捕捉および処理し、そして感染性生物、細胞片、および死滅細胞(死滅細胞由来の残骸を含む)を除去する細胞型である。このプロセスの間、APCは、遭遇したAgまたは細胞残骸の性質およびAPCの成熟/活性化レベルに依存して、炎症誘発性(proinflammatory)Th1サイトカイン(IL−12、IL−1、INF−γ、TNF−αなど)または調節/抗炎症性Th2/Th3サイトカイン(例えば、IL−10、TGF−β、IL−4など)のいずれかにより支配される応答の生成を刺激し得る。
本発明は、リン酸セリンおよびリン酸グリセロール以外の特定の反応性化学基(例えば、アニオン性リン脂質基)を含む、リポソーム、ビーズ、または類似の粒子のような本体が、哺乳動物患者に投与された際に、抗炎症効果を引き起こし、従って多くの疾患を処置するのに使用され得るという発見に関する。これらの本体はまた、それらの表面上の微量成分として、不活性構成成分、および/または異なる機構を通して活性な構成成分をさらに含む。
本発明によれば、抗炎症促進性のリガンド基をその表面に保有する薬学的に受容可能な本体が患者に投与される。何らかの1つの理論に限定されることを望まないが、これらの本体は、インビボでの炎症誘発性サイトカインの阻害および/または抗炎症性サイトカインの促進のような有益な効果を伴って、患者の免疫系と相互作用すると考えられる。反応性細胞は、免疫細胞(例えば、プロフェッショナル(professional)抗原提示細胞または非プロフェッショナル抗原提示細胞)、内皮細胞、調節細胞(例えば、NK−T細胞)などであり得る。

平均直径100±20nmのサイズのリポソームを、当該分野で公知の標準的方法に従って調製した。このリポソームは、以下の組成を有した:
群A−100% POPS(1−パルミトイル−2−オレオイル−sn−グリセロ−3−[ホスホ−L−セリン](実施例において、他に示されない限り、ホスファチジルセリンまたはPSと称する))
群B−100% POPA(1−パルミトイル−2−オレオイル−sn−グリセロ−3−ホスフェート(実施例において、他に示されない限り、ホスファチジン酸またはPAと称する)
群C−コントロール、リポソームなし。
以下の実験を行った:
1日目に、その日のリポソーム注入の後、マウスを、5mg/mlのペントバルビタールナトリウムの0.2ml腹腔内(IP)注入を使用して麻酔した。これらのマウスの腹部皮膚に70%EtOHをスプレーした。剃刀を使用して腹部から直径約1インチの毛を剃髪した。剥き出しの領域に、ピペットチップを使用して、25μlの4:1 アセトン:オリーブ油中0.5% 2,4−ジニトロフルオロベンゼン(DNFB)を塗布した。
6日目に、その日のリポソーム注入の後、マウスを以下のようにDNFBでチャレンジした:10μlの0.2% DNFBをピペットチップを用いて右耳の背部表面に塗布し、10μlのビヒクルをピペットチップを用いて左耳に塗布した。
7日目に、チャレンジの24時間後、各動物をハロタンで麻酔し、Peacockバネ式マイクロメーターを用いて耳の厚さ(μm)を測定した。耳腫脹の増加を、CHS応答の指標として使用する。データは、処置した右耳の厚さ−ビヒクル処置した左耳の厚さの差異として表す。実験を、異なるが類似の動物で3回繰り返した。種々の群間の有意差を、studentの両側t検定により決定する。p<0.05の値を、有意であるとみなす。
75%のL−α−ホスファチジルイノシトール(他に示されない限り、実施例においてホスファチジルイノシトールまたはPIと称される)および25%の1−パルミトイル−2−オレオイル−sn−グリセロ−3−ホスホコリンすなわちPOPC(他に示されない限り、実施例においてホスファチジルコリンまたはPCと称される)から本質的になるリポソームを調製し、上記のマウス接触過敏症モデルにおいて試験した。10匹のマウスの2群を1日目に感作した。1群には1、2、3、4、5および6日目に75% PI:25% PCリポソーム(各注入について、50μLの懸濁液中600,000ビヒクル)を注入した。リポソーム注入の6日後、マウスを実施例1に記載のように左耳にDNFB塗布してチャレンジした。第2のコントロール群には、同じスケジュールにしたがって50μLのPBSを投与し、同様にチャレンジした。耳の厚さの測定を7日目に行った。結果(棒グラフの形態による)を図2に示す。これらのデータは、耳の平均厚さ(×10−2mm)変化±平均の標準誤差(SEM)を表す。PBSコントロール群と比較して、PIリポソームを注入したマウスにおいて、接触過敏症(CHS)の有意な抑制が存在する(p<0.01)。
75% PIおよび25% PCの処方で平均サイズが100±20nmのリポソームを標準の方法にしたがって比較した。10匹のマウスの5群(A〜E)を、実施例1に記載の手順およびスケジュールに従って感作、注入およびチャレンジした。以下の数のリポソームを50μlの懸濁液中にて送達した:
A群 6×1010
B群 6×108
C群 6×107
D群 6×106
E群 6×105
F群 6×104。
1mlあたり4.8×1014個のリポソームを含むサイズ100±20nmの75% PIリポソームのストック懸濁液を希釈し、1mlあたり6×106個のリポソームを含む注入懸濁液を得た。このリポソーム懸濁液を使用してマウスに注入し、マウスDHSモデルにおける耳腫脹への効果を決定した。実施例1のように、雌BALB/cマウス(Jackson Laboratories)(6〜8週齢、体重19〜23g)を使用した。
マウスを1日目に感作し、6日目にチャレンジし、12日目に2回目のチャレンジをし、そして、13、14、15、16、17および18日目に、以下に示すように75% PIリポソームを注入した。リポソーム注入後18日目に、マウスをチャレンジした。リポソームを、IM注入を介して50μl容量(すなわち、1注入あたり600,000リポソーム)にて注入した。試験期間に渡っての総投与は、3,600,000リポソームであった。感作およびチャレンジを実施例1に記載のように行った。耳の厚さを19日目に測定した。
結果を、添付の図4に棒グラフの形態で示す。結果を正味の耳の腫脹(×10−2mm)として示す。これらは、19日目に、3回目の注入とその後の3回目のチャレンジの24時間後に、75% PIリポソームがDHSモデルにおいて有効であることを示す。
U937は、ホルボールエステルの投与によりマクロファージに分化し得る単球白血病細胞株である。グラム陰性細菌の細胞壁の成分である、リポポリサッカリド(LPS)を用いる処理は、U937細胞における炎症性応答を刺激し、TNFαを含む多数の炎症性分子発現をアップレギュレートする。このことは、抗炎症性治療の評価についての実験系を提供する。マクロファージは、推定抗炎症性組成物の存在下で培養培地中で増殖され得、そしてTNFαの発現を測定した。

スフィンゴ脂質代謝は、動態プロセスであることが明らかとなり、スフィンゴ脂質代謝物(セラミド、スフィンゴシンおよびスフィンゴシン−1−リン酸を含む)がここで、細胞の増殖、生存および死亡において必須の役割を果たすメッセンジャーとして認識される(Kolesnick R,J Clin Invest 110:3〜8(2002))。75%のスフィンゴミエリンおよび25%のPCから本質的になるリポソームを、標準的な方法(Katragadda Aら、Cellular and Molecular Biology Letters 5;483〜493(2000)を参照のこと)に従って調製し、接触過敏症マウスモデルにおいて試験した。使用した方法論は、実施例1と同様であり、サイズは、以前の実施例において使用されたリポソームのもの(すなわち100±20nm)と一致した。
