アサヒグループ食品(株)栃木小金井工場にて製造したサッカロマイセス(Saccharomyces)属に属するビール酵母に由来する酵母細胞壁(固形分10%)を、加水分解処理に供した。
具体的は、酵母細胞壁を水酸化ナトリウムでpH11に調整後、90℃に加熱し、18時間処理した。これをドラムドライヤーにて乾燥し、酵母細胞壁加水分解物(以下、HYCW)とした。
上記の加水分解処理後の乾燥を行わずに、塩酸でpH5.5に調整後、遠心分離して得られた重液をドラムドライヤーで乾燥したものを酵母グルカン(以下、YG)とした。また、軽液をBrix40%まで濃縮した後、125℃、40秒の条件で殺菌し、スプレードライにて乾燥したものを酵母マンナン(以下、YM)とした。
実施例であるHYCWと、比較例であるYG、YMについて、採取した試料にα-アミラーゼ、プロテアーゼ、アミログルコシダーゼを順に作用させた後に、エタノールを添加した。生成した沈殿を80%エタノール、アセトンを用いて洗浄した。その後、72% 硫酸を5mL添加し、20℃で4時間分解した後、水を70mL添加し、沸騰水浴中で2時間加水分解を行った。冷却、中和後、グルコースオキシダーゼ法によりグルコース濃度を定量し、それに0.9を乗じ、β-グルカン純度を算出した。
結果を図1に示す。HYCWを遠心分離することにより、β-グルカン画分とマンナン画分に分離することができる。沈殿を乾燥させたものがYGで、β-グルカン純度は約33%に高まり、上清を乾燥させたものがYMでβ-グルカン純度は約1%とほぼ含まれていなかった。
公知の方法に従い、IL-6、IL-10を測定した(Sonck et al,2010,Veterinary Immunology and Immunopathology 135,199-207)。14週齢の離乳子豚5頭の頸静脈から、ヘパリン管に末梢血を採血した。その後、Lymphoprepを用い、800×g・18℃・25分間の条件下で密度勾配遠心分離し、末梢血単核細胞(PBMC)を得た。塩化アンモニウムで赤血球を溶血し、350×g・18℃・10分間の遠心分離後、沈殿を10% ウシ胎児血清・非必須アミノ酸溶液・100 μg/mLピリビン酸ナトリウム・292mg/mL L-グルタミン・100 IU/mL ペニシリン・100 μg/mL ストレプトマイシン・100 μg/mL カナマイシンを含むRPMI1640培地で3回洗浄し、107 cells/mLとなるように懸濁した。
末梢血単核細胞(PBMC)に対しHYCW、YG、YMにより刺激し、IL-6、IL-10の産生量を測定した。
具体的には、20μg/mLもしくは200μg/mL の各サンプルで、マルチウェルプレート上にて1×107 cellsのPBMCを24時間刺激した。
その後、上清を回収し、市販のサイトカイン測定ELISAキット(R&D Systems社)を用いて、マニュアルに従って測定した。negative control はHBSS(Hank's Balanced Salt Solution)を使用した。
図2、3から理解できるとおり、HYCWによる刺激により、YG、YMの場合と比較してIL-6、IL-10の産生量が大きく増加していることが理解できる。
