の1つを有する基であってよい。これらの式中、m、n、p、q及びtはそれぞれ独立して1〜6であり、WはO、S又はNRbであり、L1、L3、L5、L7及びL9はそれぞれ独立して結合、O、S又はNRcであり、L2、L4、L6、L8及びL10はそれぞれ独立して結合、O、S又はNRdであり、かつVはORe、SRf又はNRgRhであり、ここでRa、Rb、Rc、Rd、Re、Rf、Rg及びRhはそれぞれ独立してH、OH、C1〜C10オキシ脂肪族ラジカル、C1〜C10一価脂肪族ラジカル、C1〜C10一価複素脂肪族ラジカル、一価アリールラジカル、又は一価ヘテロアリールラジカルである。
これらの実施形態の2種の生体適合性の酸化鉄ナノ粒子を、以下に記載される手順に従って製造した。
FeCl2・4H2O(11.6g、0.058モル)、FeCl3・6H2O(11.6g、0.096モル)及び水(400mL)の混合物を、三ツ口フラスコ内にて25℃、300rpmで撹拌した。そのフラスコに、水酸化ナトリウム溶液(2.5N、170mL)を47μl/秒の速度で添加することで、11〜12のpH値が得られた。FeCl2・4H2O(11.6g、0.058モル)、FeCl3・6H2O(11.6g、0.096モル)及び水(400mL)の混合物を、三ツ口フラスコ内にて25℃、300rpmで撹拌した。そのフラスコに、水酸化ナトリウム溶液(2.5N、170mL)を47μl/秒の速度で添加することで、11〜12のpH値が得られた。引き続き、オレイン酸(20mL)を添加し、30分間にわたり撹拌し、引き続き6NのHCl溶液を添加することで、pH値を約1へと調整した。該混合物からこうして析出した酸化鉄コアを濾過により回収し、水で4回又は5回にわたり洗浄して、過剰のオレイン酸を除去した。次いでそれを真空下で乾燥させて、以下に記載されるようにして、生体適合性ポリマーとのカップリングのために使用した。
生体適合性ポリマーのmPEG−シラン−750を、以下に記載される手順に従って製造した。
こうして得られた生体適合性ポリマーのmPEG−シラン−750及びmPEG−シラン−2000のそれぞれ(250g)を、上記の通りに製造した酸化鉄コア10gを含有する1L〜1.2Lのトルエン溶液中に懸濁した。その懸濁液を24時間にわたり撹拌し、引き続き水(1.5L)を添加して抽出を行った。抽出された水溶液を限外濾過装置で濾過し、水で洗浄し、次いで100mLにまで濃縮することで、生体適合性の酸化鉄ナノ粒子の懸濁液が得られた。該酸化鉄ナノ粒子は、mPEG−シラン−750から製造されたか、mPEG−シラン−2000から製造されたかにかかわらず、iTrastと呼ぶ。
こうして得られた生体適合性の磁性ナノ粒子iTrastの透過電子顕微鏡法(TEM)画像を、JEOL社製JEM−2100F型電界放出形透過電子顕微鏡法を用いて撮影した。それらの画像により、iTrastが10nm〜12nmの寸法の酸化鉄コアを有することが裏付けられた。
移植された臓器においてマクロファージをトラッキングする研究は、以下に記載される手順に従って実施した。
異所性灌流心モデルを使用するための手術法はPNAS, 2006, 103(6):1852-1857に記載されている。近交系ブラウンノルウェー(BN、RT1n)ラット及び近交系ダークアグーチ(DA、RT1a)ラットを、ハーランラボラトリーズ社(Harlan Laboratories Inc.)(インディアナ州インディアナポリス)から入手した。異なる系統のラット間での異系移植(DA→BN)では拒絶反応が生じたが、同じ系統のラット間での同系移植(DA→DA又はBN→BN)では拒絶反応は起きなかった。心臓移植片の拒絶反応グレードを、病理組織学的にJ. Heart LungTransplant., 1998, 17, 754-760及びJ. Heart Transplant., 1990, 9, 587-593に記載されている指標基準に従って決定した。
主要組織適合複合体(MHC)が一致していないブタを、高用量のタクロリムスで12日間にわたり処置した。次いで、腎臓異種移植片(n=5)を、これらのブタへと移植した。予想通り、14日目に、全ての単離された腎臓異種移植片は、血清クレアチニン濃度が0日目の濃度と比較して二倍になったことから拒絶反応を示した。
以下に示される手順に従って、リンパ節の形態変化を検出するために、iTrastを調べた。
本明細書で開示された特徴は全てあらゆる組合せで組み合わせることができる。本明細書で開示される各特徴は同じ、同等の、又は同様の目的を果たす代替特徴に置き換えることができる。そのため特に明記しない限り、開示される各特徴は一連の包括的な同等又は同様の特徴の例にすぎない。
