Abstract
【選択図】 図1A
Description
別の具体的な実施例として、前記マイクロニードルアレイの単位用量は、前記基底層を切断する必要がなく、予め選択した形状で製造することができる。例えば、ポリマーフィルムを特定の形状で分配し、印刷、スクリーン印刷、マイクログラビア印刷、ジェット印刷、はがすことのできるテンプレートにより、または基質材料に液体フィルムを貼付し、形状を作る他の方法により、基底部または基底層を形成することができる。一部の実施例では、針はピンテンプレートまたは同等物を前記ポリマーフィルムに接触させ、前記フィルムの蒸発乾燥と同時に前記ピンテンプレートを引き抜き、本明細書に説明した方法のいずれかにより突起または突出したアレイを形成することができる。さらなる一部の実施例では、予め選択した基底層が、望みの長さに突出を切断または整え、選択的に前記支持基質を除去することで形成することができる。特に、前記予め選択した形状が連続で均一な基底層である必要はなく、一部の実施形態では、得られた形状で孔を形成する基底層に間隙があることが望ましい。一部の実施例では、当業者が認識するとおり、穿孔として副次的単位への分離を促すよう、またはさらに前記装置の柔軟性または硬性、蒸気透過性、重量、材料費、および前記単位用量の他の特性に影響するようにそのような孔を配置することができる。
マイクロニードルアレイは、ピンテンプレートを20%wt.ポリビニルアルコール(PVA)溶液の厚さ1mmのフィルムに接触させ(図3A、左図および中央図)、空気流をコントロールしながら前記テンプレートを引き抜き、充填可能な通路を有する繊維状構造を形成することで生成した(図3A、右図および3B)。乾燥した針構造は前記テンプレートとは分け、機械的に整え、均一な高さで鋭い斜めの先端を持つようにした(図3C)。典型的なマイクロニードルの製造および乾燥は50℃以下で行われ(低い場合は30℃、データは示されていない)、核酸の機能が残るようにする。前記装置は、完全な材料の支持層を持つ、規則的な吸収性マイクロニードルアレイとして前記基質から除去する(図3D)。典型的には、前記マイクロニードルアレイのマイクロニードルは厚さ100μm未満で直径わずかミクロンの鋭い先端を持つ(図3E)。マイクロニードルアレイには、核酸、薬物、ワクチン、または他の治療薬など、充填材料の水溶液または懸濁液を充填することができる。複数の充填材料を同じアレイの別の針集団から送達することができる(図3F)。充填の柔軟性を示すため、フィコビリンタンパク質であるRフィコエリスチンおよびフルオレセインを代わりにアレイに充填し、複数の積荷を単一装置に送達することができる(図3F)。
本発明者は、汗孔を可視化するために使用されることが多いヨウ素−デンプン複合体の膜による適応を開発し、これは薄く柔軟性のあるポリビニルアルコール(PVA)およびマルトデキストリンフィルムを有する。ヨウ素存在下では、このフィルムは吸水すると急速に発色する。このフィルムアプローチは、乾燥デンプン顆粒またはオイルに分散した顆粒を用いたより一般的なアプローチと比較してかなり利点がある。乾燥膜でのデンプンの均一な分布を反映して前記フィルムは高い分解能で発色を示し、前記フィルム内で発色し、発色が基底組織の基質から消失した後可視化され、標準的な電子的方法で永久的に記録(スキャン)されるようにすることで、被験者皮膚の不規則な表面に見られる視覚的解析を大幅に省き、汗レベルの定量的比較が行いやすくなる。
図7A〜7Cに図示されるとおり、BTA投与後の発汗量の抑制は、デンプン/PVAフィルムに曝露してから3分以内で明らかである。より具体的には、投与を行わなかった場合の陰性対照の足蹠を図7Aに図示し、各足で染色強度が同等であることを示している。図7Bは、食塩水の陰性対照(左)および50単位のBTA食塩水溶液(右)を皮内注射後24時間で観察した足蹠を示す。前記BTAを投与した足は薄い染色を示し、発汗量の減少と一致している。同様に、図7Cは、ブランクのマイクロニードルアレイ(Flex−PAD)(左足)およびBTA充填Flex−PAD(約50単位のBTAを送達、右足)を適用する処理後4日で解析された足蹠を示す。前記Flex−PADでBTAを送達した足(右)は、BTAを介した発汗量の減少と一致した薄い染色を示している。
雌Swiss−Webster(SW)マウスを評価し、尾懸垂または「scruffing」時の正常な指外転反射および正常で指を開ききった状態を観察した。前記被験者を麻酔し、合計約60ngのBTAを充填したマイクロニードル9本を有する単一のFlex−PAD単位用量を、各被験者の右腓腹筋にかかる皮膚の毛を剃って適用した。BTAの代わりに約5ngのUSPリン酸リボフラビンを充填した対照単位用量(対照)を、同じように、左腓腹筋にかかる皮膚の毛を剃って適用した。単位用量は指のピンチ挿入で適用し、5分間放置した。この後、投与後の単位用量を点検し、針の50%以上にかなりの浸食のエビデンスが示され、前記用量は全積荷を送達しなかった可能性があるが、かなりの部分が沈着したことを示している。
