KCGP(f106〜169)及びKCGPZ(f106〜169)の調製
カゼイン−HClを最終濃度が21.5g/Lになるまで50℃で脱イオン水に溶解し、pHを1MのNaOHの添加により8.0に維持した。それから温度を37℃まで低下させ、カゼインの沈殿を避けるためにpHを1MのHClの添加により6.3に調整した。カゼインを加水分解するために、レンネット(90%キモシン;EC 3.4.23.4;145国際凝乳単位[IMCU]/mL;単一濃度;Chr. Hanson)を最終濃度が1.2 IMCU/g(カゼイン)になるまで添加し、溶液を37℃で1時間撹拌した。加水分解をトリクロロ酢酸を4%の最終濃度まで添加することにより停止させ、沈殿したタンパク質を遠心分離(5000g、15分、4℃)により塊にした。κ−カゼイン(106〜169)カゼイノマクロペプチド(CMP)を含有する上清を濃縮し、3000Daカットオフ膜(S10Y3、Amicon/Millipore)による透析濾過を用いてH2Oで洗浄し、KCGP(f106〜169)を生成した。残余分を高速液体クロマトグラフィ(HPLC)及び質量分析により分析した。KCGPZ(f106〜169)を20mMのZnCl2を10mg/mLのKCGP(f106〜169)調製物に添加することにより調製した。この溶液がバイオフィルムアッセイに使用したKCGPZ(f106〜169)溶液であった。
上記のように調製されたKCGP(f106〜169)を0.1%(v/v)トリフルオロ酢酸(TFA)の水溶液(溶媒A)に溶解し、Agilent 110 HPLCシステムに取り付けられたC18半分取RPカラム(250×10mm、Vydac)に適用した。ペプチドを開始流速0.1mL/分(最初の1分で3.5mL/分まで増大させる)で5%溶媒Bを用いて溶出させた。次の1分で溶媒Bの勾配を15%まで、その後10分で溶媒Bの勾配を15%から30%まで、24分で溶媒Bの勾配を30%から48%まで、2分で溶媒Bの勾配を48%から100%まで増大させた。溶媒Bは0.085%(v/v)TFAを含有する20%水とともに80%アセトニトリルを含有していた。溶出液を215nmの主波長を用いてモニタリングした。18分〜23分の溶出で回収した画分を回収し、プールして、凍結乾燥した。KCGの算出収率はKCGP(f106〜169)の24%であった。
上記のように調製した際のKCGP(f106〜169)は43%非グリコシル化κ−カゼイン(106〜169)と、24%グリコシル化κ−カゼイン(106〜169)とを含有していた。この材料を逆相HPLCにより更に精製し、グリコシル化形態のκ−カゼイン(106〜169)を非グリコシル化形態と分離した(図4)。18分〜23分で溶出したグリコシル化形態のκ−カゼイン(106〜169)を回収し、ここではKCGと称した。
単一特異性バイオフィルムのフローセル培養及びCSLM分析
フローセルにおけるストレプトコッカス・ミュータンスのバイオフィルム培養は、幾つかの修正点があるが、Wen et al. (2006)により記載されたものと同様のものであった。3チャネルフローセルシステム(Stovall Life Science, Greensboro, North Carolina, USA)を細菌バイオフィルムの接種、検査及び染色用の止め栓を用いて改良した。すべてのパーツを組み立て、0.5%次亜塩素酸ナトリウムをポンプにより投入し、一晩そのままにした。それから滅菌水(200mL)を用いて、システムを洗い流した後、成長培地を添加した。システムに1×107細胞/mLの細胞密度まで希釈した1mLの対数増殖期のストレプトコッカス・ミュータンスIngbritt株の培養物を接種した。システムを1時間インキュベートした後、2.5mMのDTT及び0.5g/Lのスクロースを添加した25% ASM(ASM;2.5g/LのII型ブタ胃ムチン、2.0g/Lの細菌性ペプトン、2.0g/Lのトリプトン、1.0g/Lの酵母エキス、0.35g/LのNaCl、0.2g/LのKCl、0.2g/LのCaCl2及び1mg/Lのヘミン(pH7.0))を一定速度で流した(0.2mL/分)。16時間後、1mLの精製グリコシル化κ−カゼイン(106〜169)(KCG);KCGP(f106〜169);KCGPZ(f106〜169)(KCGPZ(f106〜169);10mg/mL KCGP(f106〜169)及び20mMのZnCl2);20mMのZnCl2;0.1%ジグルコン酸クロルヘキシジン又は滅菌水をシステムの各チャネルに注入し、10分間インキュベートした後、25% ASM流を10分間再開し、その後染色した。初期段階のバイオフィルムに対する処置の効果を求めるために、システムを接種後6時間インキュベートして、1mLの試験溶液で10分間処置して、25% ASM流を更に16時間再開して、バイオフィルムの回復を観察した。それからBacLight LIVE/DEAD染色(Molecular Probes)を用いて、in situでバイオフィルムを染色した。
生体測定データを、定着したバイオフィルムに対するKCGP(f106〜169)、KCG、KCGPZ(f106〜169)、亜鉛及びクロルヘキシジンの効果を研究するために、固定要因として含まれる処置と、無作為遮断因子として実験とを有する2要因の分散分析(ANOVA)モデルを用いて分析した。処置差が有意であった場合、処置差の事後比較を、チューキー事後検査を用いて行った。モデルの適合を残差プロットで確認し、正規性を正規確率プロット及びコルモゴルフ・スミルノフ検定を用いて調べ、誤差分散の均一性を、ルビーン検定を用いて検査した。誤差分散が不均一であった場合、データの自然対数変換を用いて、処置群の分散を安定化させた。それから変換したデータに対してANOVAを用いて処置を比較した。6時間のストレプトコッカス・ミュータンスのバイオフィルムに対するKCGPZ(f106〜169)の効果を調べる実験から得られた生体測定データを、対応のあるサンプルのT検定を用いて分析した。すべての分析を、SPSS統計ソフトウェア(バージョン17.0、SPSS Inc., Chicago, IL)を用いて実施した。
複数種の口腔バイオフィルム培養物
それから、KCGPZ(f106〜169)を、一般的に齲蝕の発症及び進行に関連する日和見病原菌を含む、歯肉縁上の歯垢の主要種を表すために選択された6つの細菌種からなる多菌性バイオフィルムに対して試験した。バイオフィルムの細菌成長培地(ASM)を、唾液の高糖タンパク質組成を模倣するように設計し、食事摂取を模倣するために炭水化物とタンパク質との混合物をCDFFに1日に4回加えた。
KCGP(f106〜169)とKCP(f106〜169)との抗バイオフィルム有効性の比較
KCGP(f106〜169)[GP]及び非グリコシル化κ−カゼイン(106〜169)[KCP(f106〜169)]を、カゼイン塩のキモシンによる加水分解、及び実施例1に記載されたような逆相HPLCにより、並びにMalkoski et al (2001)及びDashper et al (2005)によりこれまでのように調製した。調製物の純度をマトリクス支援レーザー脱離イオン化飛行時間質量分析法を用いて確認した(Malkoski et al, 2001)。
大便連鎖球菌ATCC 15036株を−20℃で保存した。バイオフィルムの抗菌アッセイを、滅菌96ウェルマイクロタイタープレート(Becton Dickinson, Franklin Lakes, NJ, USA)において実施した。滅菌したブレインハートインフージョン培地(BHI:37g/L;Oxoid Ltd., Cambridge, UK)をすべての実験で成長培地として使用した。BHI寒天プレート上の細菌をコロニー形成単位(CFU)として計数した。
