Description
GQDsは、2012年Nano Lettersに発表された論文[Nano lett,12,844−849(2012)]を参考にして製造した。カーボンファイバを、硫酸と窒酸を3:1の割合で混合した溶液に入れた後、80℃で24時間加熱した(thermo−oxidation process)。反応が終了した後、透析過程、真空濾過などを通じて精製し、Rotovapで最終的にパウダー状のGQDsを収得した。このように作られたGQDsは、構造的に非常に様々なサイズ(約5nm〜約20nm)を有する粒子の形態で収得された(図1)。製造されたGQDsの他の特徴としては、UVランプで蛍光を示し(放出:490nm及び550nm)(JASCO FP−8300 Fluorescence Spectrometer)(図2)、808nmのNIRレーザを照射すると光熱(photothermal)効果を示した。FT−IR分析スペクトル(Thermo Scientific Nicolet iS 10 FT−IR Spectrometer)を見ると、GQDsの末端のカルボキシル基(−COOH)が1724cm−1で、芳香族C=Cピークが1614cm−1で観測された(図3)。最後に、ゼータ電位(Malvern Zetasizer Nano ZS)を通じて分析した表面の電荷は約−20mVであることが示された(図4)。
前記製造されたグラフェンナノ構造体(GQDs)の末端にある作用基に神経タンパク質をターゲティングする物質であるコンゴーレッドを結合した物質を下記の反応式のように反応させて製造した。前記コンゴーレッドの量を異ならせることで(100μg/mL、250μg/mL及び500μg/mL)、サンプル1、2、及び3をそれぞれ製造した。
グラフェン量子ドットのフィブリル化抑制効果を、PFFs(pre−formed fibrils)というアルファシヌクレイン(alpha−synuclein)実験モデルを使用して決定した。具体的に、PFFsをニューロンに注入した後、一週間程経過するとフィブリルが形成され、これは、結局、ニューロンの壊死を誘発した。フィブリル化はアルファシヌクレインのリン酸化をもたらし、これは、図5に示すように染色されたイメージとして確認することができる。PFFs(1μg/mL)のみをニューロンに注入した際は稠密であったp−a−syn(phosphorylated alpha−synuclein)が、GQDs(1μg/mL)を注入すると、殆ど何も注入していない水準までなくなることが確認された(図5)。図5から分かるように、p−a−synを約80%まで減少させており、これは、事実上、殆ど完全にフィブリル化を抑える水準であると解釈されることができる。また、ニューロンの生存率も約20%程増加した(図6b)。GQDsのみを注入した場合のニューロンの生存率(TUNEL検定で分析)は、むしろPBS培地のみを注入した場合よりも良い結果となり、GQDsにニューロンへの毒性がないことが確認された(図6a及び図6b)。図6aの左側は損傷された細胞が赤の染色で表示されるタネル検定であり、中間部分は細胞核内のDNAが青の染色で表示されるDAPI染色であり、右側はこれらの定量(quantification)である。
単にフィブリル化を抑え、ニューロンの生存率を高めることも重要であるが、退行性神経疾患の治療及び疾病の進行速度を遅らせるためには、周辺のニューロンに転移(transmission)されることを防ぐことが非常に重要である。その事実を確認するために、マイクロ流体デバイス(microfluidic device)をセットし、GQDsをどのチャンバ内に注入した場合に転移される過程を防ぐことができるかを確認した。図8aは簡単な実験の模式図であり、図8bはその実験結果を示すものである。C1(chamber 1)の場合、1つ目のチャンバにあるニューロンにGQDsを注入し、C2(chamber 2)の場合、2つ目のチャンバにあるニューロンにGQDsを注入した後、アルファシヌクレインのフィブリル化が周辺のニューロンに広がることを確認した。GQDsなしにPFFsのみがある陽性対照群の場合、フィブリル化が進行されたアルファシヌクレインが1つ目から3つ目のチャンバまで転移されたことが観察された。次に、1つ目のニューロンにGQDsを注入したデバイスの場合、そもそもフィブリル化があまり進行されておらず、それにより、2つ目及び3つ目のニューロンでもアルファシヌクレインのフィブリル化が殆ど観測されなかった。最後に、中間のニューロンにGQDsを注入したデバイスでは、1つ目のチャンバではある程度フィブリル化が進行されたが、GQDsが注入されている2つ目のニューロンからはその量が確実に減少し、続いて最後のニューロンでは殆どフィブリル化が進行されていないことが観察された。このデバイスにおいて、陽性対照であるPFFsのみを注入したデバイスと比べて初期フィブリル化の程度が異なるのは、デバイスに内在したエラーであり、GQDsがデバイス上で各ニューロン毎に完璧に分離されることができなかったためであると思われる。
細胞内の実験と同様な方式でサンプリングを進行し(1μg/mLのGQDsと1μg/mLのPFFsを37℃でインキュベーションした後、シリカ基材上にサンプリング)、GQDsによるフィブリル化の抑制をOM(optical microscope)によって分析した結果、PFFsのみをインキュベーションした場合は、フィブリルの凝集と予想される大きな固まりが観察されたのに対し(図9の(a)及び(b))、GQDsを共にインキュベーションした場合は、GQDsとアルファシヌクレインオリゴマが絡まれているようなイメージが観察された(図9の(c)及び(d))。本結果の総アルファシヌクレイン及びGQDsの量が多すぎたし、これらの構造を明確に明かす程に鮮明なイメージではなかったが、2つのサンプルの結果が明らかに異なることは確認することができた。
前記製造例1で製造されたGQDsとコンゴーレッド溶液(対照群)に赤外線レーザを照射して、蛍光発光現象を暗い所で撮影し、その結果を図13に示した。
様々な試料(前記製造例1及び2で製造されたGQDs、サンプル1、サンプル2、サンプル3及び比較例としてコンゴーレッド溶液)を用いてFT−IR分析、蛍光発光測定実験を行った。
