乳酸菌の免疫賦活作用を高めるエステル結合物として親水性部分として多価アルコールを用い得ることが確認されたため、次に疎水性部分の検証を行った。
<方法>
実施例1に記載の方法により作製した細胞懸濁液500μlに乳酸菌(JCM5805株)と図3に記載のサンプルの混合物を各5μlずつ添加しCO2インキュベータ内で37℃、5% CO2にて培養した。乳酸菌と図に記載の各サンプルの混合物は、乳酸菌0.1(w/v)%と各サンプル0.25(w/v)%を含む。サンプルは乳酸菌のみ、リョートーシュガーエステルP-1570(主にショ糖パルミチン酸エステルを含む)(PA1)(三菱化学フーズ株式会社)、リョートーシュガーエステルP-1670(主にショ糖パルミチン酸エステルを含む)(PA2)(三菱化学フーズ株式会社)、リョートーシュガーエステルS-1570(主にショ糖ステアリン酸エステルを含む)(SA1)(三菱化学フーズ株式会社)、リョートーシュガーエステルS-1670(主にショ糖ステアリン酸エステルを含む)(SA2)(三菱化学フーズ株式会社)及びリョートーシュガーエステルO-1570(主にショ糖オレイン酸エステルを含む)(OA)(三菱化学フーズ株式会社)であった。24時間後に培養上清を回収しインターフェロン-α測定キット(PBL社製)にてインターフェロン-α濃度を測定した。すなわち、親水性部分をショ糖に統一し、疎水性部分としてパルミチン酸(飽和脂肪酸)、ステアリン酸(飽和脂肪酸)及びオレイン酸(不飽和脂肪酸)を脂肪酸して含むエステル結合物を使用することで疎水性部分の検証を行った。
<結果>
図3に結果を示す。0.1%JCM5805単独でインターフェロン-α誘導活性を示し、更に疎水性部分に飽和脂肪酸であるステアリン酸及びパルミチン酸を含むエステル結合物ではインターフェロン-α誘導活性が高められ、不飽和脂肪酸であるオレイン酸を含むエステル結合物ではインターフェロン-α誘導活栓が弱められた。すなわち、乳酸菌の免疫賦活作用を高めるエステル結合物として疎水性部分は飽和脂肪酸が適切であることが示された。
乳酸菌の免疫賦活作用を高めるエステル結合物を詳細に検証するために、単一成分であるモノグリセリンミリスチン酸エステル、モノグリセリンパルミチン酸エステル及びモノグリセリンステアリン酸エステルを用いて多価アルコールと脂肪酸のエステル結合物の評価を行った。
<方法>
実施例1に記載の方法により作製した細胞懸濁液500μlに乳酸菌(JCM5805株)と図4に記載のサンプルの混合物を各5μlずつ添加しCO2インキュベータ内で37℃、5% CO2にて培養した。乳酸菌と図に記載の各サンプルの混合物は、乳酸菌0.1(w/v)%と各モノグリセリン脂肪酸エステルのサンプル0.25(w/v)%を含む。サンプルは乳酸菌のみ、モノグリセリンミリスチン酸エステル、モノグリセリンパルミチン酸エステル、モノグリセリンステアリン酸エステルであった。24時間後に培養上清を回収しインターフェロン-α測定キット(PBL社製)にてインターフェロン-α濃度を測定した。すなわち、親水性部分がグリセリンであり疎水性部分がミリスチン酸、パルミチン酸及びステアリン酸であるエステルの単一成分の検証を行った。
<結果>
図4に結果を示す。0.1% JCM5805単独でインターフェロン-α誘導活性を示し、更に疎水性部分にミリスチン酸、パルミチン酸及びステアリン酸を含むモノグリセリン脂肪酸エステルではインターフェロン-α誘導活性が高められた。すなわち、エステル結合物として親水性部分がグリセリンであり疎水性部分が飽和脂肪酸である単一成分でも乳酸菌の免疫賦活作用を高めることが示された。
乳酸菌の免疫賦活作用を高めるエステル結合物を詳細に検証するために、単一成分であるショ糖パルミチン酸エステルを用いて多価アルコールと脂肪酸のエステル結合物の評価を行った。
<方法>
雌129/SVマウスの骨髄細胞を常法に従って回収し赤血球除去処理を行った。得られた骨髄細胞を10%FBS、50μM β-メルカプトエタノール、100ng/ml Flt-3Lを含有するRPMI培地(SIGMA社製)に、5×105個/mlとなるように懸濁した。得られた細胞懸濁液を1mlずつ播種し、CO2インキュベータ内で37℃、5%CO2にて1週間培養して樹状細胞を誘導した。1週間培養後、播種された1ml細胞培養液中に乳酸菌(JCM5805株)と図5に記載のサンプルの混合物を各10μlずつ添加した。乳酸菌と図5に記載の各サンプルの混合物は、乳酸菌0.1(w/v)%と各サンプル0.25(w/v)%を含む。サンプルは乳酸菌のみ、ショ糖パルミチン酸エステル及びリョートーシュガーエステルP1670(主にショ糖パルミチン酸エステルを含む)(三菱化学フーズ株式会社)であった。24時間後に培養上清を回収しインターフェロン-α測定キット(PBL社製)にてインターフェロン-α濃度を測定した。
<結果>
図5に結果を示す。0.1% JCM5805単独でインターフェロン-α誘導活性を示し、更にショ糖パルミチン酸エステルではリョートーシュガーエステルP1670と同程度までインターフェロン-α誘導活性が高められた。すなわち、エステル結合物として親水性部分がショ糖であり疎水性部分が飽和脂肪酸である単一成分でも乳酸菌の免疫賦活作用を高めることが示された。
乳酸菌の免疫賦活作用を高めるエステル結合物として親水性部分は多価アルコールが適切であり、疎水性部分は飽和脂肪酸が適切であることが確認されたため、次にエステル結合物の多価アルコール部分の有機酸修飾の有無に関する検証を行った。
(1)乳酸菌濃度0.1%の場合
<方法>
実施例1に記載の方法により作製した細胞懸濁液500μlに乳酸菌(JCM5805株)と図6に記載のサンプルの混合物を各5μlずつ添加しCO2インキュベータ内で37℃、5% CO2にて培養した。乳酸菌と図に記載の各サンプルの混合物は、乳酸菌0.1(w/v)%と各サンプル0.25(w/v)%を含む。サンプルは乳酸菌のみ、エマルジーP-100(主にモノグリセリンと飽和脂肪酸のエステル結合物を含む)(A)(理研ビタミン株式会社)、ポエムW-60(主にジアセチル酒石酸モノグリセリンと飽和脂肪酸のエステル結合物を含む)(B)(理研ビタミン株式会社)、ポエムB-15V(主にコハク酸モノグリセリンと飽和脂肪酸のエステル結合物を含む)(C)(理研ビタミン株式会社)及びポエムBS-20(主にコハク酸モノグリセリンと飽和脂肪酸のエステル結合物を含む)(D)(理研ビタミン株式会社)であった。24時間後に培養上清を回収しインターフェロン-α測定キット(PBL社製)にてインターフェロン-α濃度を測定した。すなわち、エステル結合物の親水性部分をモノグリセリンに、疎水性部分を飽和脂肪酸に統一し、それに有機酸修飾として酒石酸又はコハク酸が結合したエステル結合物を使用することで有機酸修飾の検証を行った。
<結果>
図6に結果を示す。0.1% JCM5805単独でインターフェロン-α誘導活性を示し、有機酸修飾のない乳化剤ではインターフェロン-α誘導活性が高められたが、酒石酸及びコハク酸で修飾されたエステル結合物ではlFN-α誘導活性が高められなかった。すなわち、乳酸菌の濃度が比較的高い場合は、乳酸菌の免疫賦活作用を高めるエステル結合物として疎水性部分は飽和脂肪酸であり、有機酸修飾されていないものが適していることが示された。
(2)乳酸菌濃度0.01%の場合
<方法>
実施例1に記載の方法により作製した細胞懸濁液500μlに乳酸菌(JCM5805株)と図7に記載のサンプルの混合物を各5μlずつ添加しCO2インキュベータ内で37℃、5% CO2にて培養した。乳酸菌と図に記載の各サンプルの混合物は、乳酸菌0.01(w/v)%と各サンプル0.25(w/v)%を含む。サンプルは乳酸菌のみ、エマルジーP-100(主にモノグリセリンと飽和脂肪酸のエステル結合物を含む)(A)(理研ビタミン株式会社)、ポエムW-60(主にジアセチル酒石酸モノグリセリンと飽和脂肪酸のエステル結合物を含む)(B)(理研ビタミン株式会社)、ポエムB-15V(主にコハク酸モノグリセリンと飽和脂肪酸のエステル結合物を含む)(C)(理研ビタミン株式会社)及びポエムBS-20(主にコハク酸モノグリセリンと飽和脂肪酸のエステル結合物を含む)(D)(理研ビタミン株式会社)であった。24時間後に培養上清を回収しインターフェロン-α測定キット(PBL社製)にてインターフェロン-α濃度を測定した。すなわち、エステル結合物の親水性部分をモノグリセリンに、疎水性部分を飽和脂肪酸に統一し、それに有機酸修飾として酒石酸又はコハク酸が結合したエステル結合物を使用することで有機酸修飾の検証を行った。
<結果>
図7に結果を示す。0.01%JCM5805単独でインターフェロン-α誘導活性を示し、有機酸修飾のない乳化剤ではインターフェロン-α誘導活性が高められ、酒石酸及びコハク酸で修飾されたエステル結合物では誘導活性の向上が小さくなったが、わずかに活性の上昇が認められた。すなわち、乳酸菌の濃度が低い場合は、乳酸菌の免疫賦活作用を高めるエステル結合物として疎水性部分は飽和脂肪酸であり、有機酸修飾されていてもいなくても効果があることが示された。
<方法>
実施例1に記載の方法により作製した細胞懸濁液500μlに乳酸菌(JCM5805株)と図8に記載のサンプルの混合物を各5μlずつ添加しCO2インキュベータ内で37℃、5% CO2にて培養した。乳酸菌と図に記載の各サンプルの混合物は、乳酸菌0.1(w/v)%と各サンプル0~1(w/v)%を含む。サンプルとしてリョートーシュガーエステルP1670(主にショ糖パルミチン酸エステルを含む)(三菱化学フーズ株式会社)を用いた。24時間後に培養上清を回収しインターフェロン-α測定キット(PBL社製)にてインターフェロン-α濃度を測定した。すなわち、JCM5805株の濃度を0.1(w/v)%に固定しエステル結合物であるリョートーシュガーエステルP1670の濃度を0.05(w/v)%から1(w/v)%の間で濃度依存性を検証した。
<結果>
図8に結果を示す。0.1(w/v)%JCM5805単独でインターフェロン-α誘導活性を示し、リョートーシュガーエステルP1670の濃度幅が0.05(w/v)%から0.5(w/v)%の間で濃度依存的にインターフェロン-α誘導活性が相乗的に高まった。すなわち、JCM5805濃度1に対して、エステル結合物濃度0.5~5の間で相乗効果を示した。エステル結合物濃度1(w/v)%で相乗効果が見られなかったのは、エステル結合物濃度が濃く細胞に傷害を与えたためと考えられる。
<方法>
実施例1に記載の方法により作製した細胞懸濁液500μlに乳酸菌(JCM5805株)と図9に記載のサンプルの混合物を各5μlずつ添加しCO2インキュベータ内で37℃、5% CO2にて培養した。乳酸菌と図に記載の各サンプルの混合物は、乳酸菌0.01(w/v)%と各サンプル0~0.5(w/v)%を含む。サンプルとしてリョートーシュガーエステルP1670(主にショ糖パルミチン酸エステルを含む)(三菱化学フーズ株式会社)を用いた。24時間後に培養上清を回収しインターフェロン-α測定キット(PBL社製)にてインターフェロン-α濃度を測定した。すなわち、JCM5805株の濃度を0.01(w/v)%に固定しエステル結合物であるリョートーシュガーエステルP1670の濃度を0.05(w/v)%から0.5(w/v)%の間で濃度依存性を検証した。
<結果>
図9に結果を示す。0.01%JCM5805単独でインターフェロン-α誘導活性を示し、リョートーシュガーエステルP1670濃度依存的にインターフェロン-α誘導活性が相乗的に高まった。相乗効果を示したエステル結合物濃度は0.05~0.5(w/v)%の間であり、JCM5805濃度1に対して、エステル結合物濃度5~50で相乗効果を示した。
<方法>
実施例1に記載の方法により作製した細胞懸濁液500μlに乳酸菌と図10に記載のサンプルを各5μlずつ添加しCO2インキュベータ内で37℃、5% CO2にて培養した。24時間後に培養上清を回収しインターフェロン-α測定キット(PBL社製)にてインターフェロン-α濃度を測定した。すなわち、乳酸菌としてEnterococcus faecalis及びLactobacillus brevis subsp. coagulansに対するエステル結合物(リョートーシュガーエステルP-1670(ショ糖パルミチン酸エステル)(三菱化学フーズ株式会社))の影響について検証した。
<結果>
図10に結果を示す。Enterococcus faecalis及びLactobacillus brevis subsp. coagulansそれぞれ単独でインターフェロン-α誘導活性を示し(図10B及びD)、リョートーシュガーエステルP-1670によってインターフェロン-α誘導活性が高められた(図10C及びE)。これより、多価アルコールと脂肪酸のエステル結合物によって免疫賦活作用が高められる乳酸菌として、JCM5805株に限定されないことが示された。
