)之乳酸菌菌體、其培養物或發酵物或者其所產生之多醣類作為有效成分之組成物對於預防或改善第IV型過敏甚是有效,尤其可供用作用以預防或改善接觸性皮膚炎之飲食品、醫藥品、飼料及化妝品。
Description
本發明關於一種第IV型過敏用組成物。更詳言之,本發明有關於一種用以預防或改善第IV型過敏(尤其是接觸性皮膚炎)之組成物,其以屬於副乾酪乳酸桿菌(Lactobacillus paracasei)之乳酸菌菌體、其培養物或發酵物或者其所產生之多醣類作為有效成分。
背景技術
近年來,由於飲食生活變化、大氣污染惡化以及暴露於過敏原物質及金屬飾品等各種原因,已指出花粉症及異位性皮膚炎、接觸性皮膚炎等過敏顯著增加。過敏被視為肇因於免疫反應之對活體之全身或局部性障礙。而過敏大致分為因血中抗體所致體液性免疫反應而起之第I、II及III型過敏以及因致敏淋巴球所致細胞性免疫反應而起之第IV型過敏。第IV型過敏也稱為延遲型過敏、細胞性免疫、結核菌素型,咸認係由與抗原發生專一性反應之致敏T細胞所引起。咸認第IV型過敏時,使巨噬細胞活性化之因子等各種生理活性物質會自與抗原發生反應之致敏T細胞遊離而引發周圍組織之傷害。第IV型過敏有結核菌素反應及接觸性皮膚炎等,此種過敏之皮內反應通常會在實施抗原皮內注射24~48小時後發紅、變成硬塊而表現出。
可對此種過敏使用之藥物有抗組織胺劑及類固醇藥等。然而,此等藥物已被指出顯示各種副作用而未必安全。
在此種狀況下,近年來,涉入免疫反應且具抗過敏作用之乳酸菌作為高安全性之抗過敏素材而受到矚目。舉例來說,已提出短毛乳酸桿菌(Lactobacillus brevis)等可抑制IgE抗體產生之乳酸菌(專利文獻1)、具有組織胺遊離抑制效果之洛德乳酸桿菌(Lactobacillus reuteri)(AD0002菌株)之乳酸菌(專利文獻2)、可活化腸道免疫或第I型輔助T細胞之屎腸球菌(Enterococcus faecium)乳酸菌(專利文獻3及4)以及具Th1免疫增強作用與Th2免疫抑制作用之副乾酪乳酸桿菌(Lactobacillus paracasei)KW3110菌株之乳酸菌(非專利文獻1)等。

用以實施發明之形態
以下,針對本發明所提供,以屬於副乾酪乳酸桿菌(Lactobacillus paracasei)之乳酸菌菌體、其培養物或發酵物或其所產生之多醣類作為有效成分之用以預防或改善第IV型過敏之組成物予以詳細說明。
1.本發明中作為對象之乳酸菌
本發明中作為對象之乳酸菌為屬於副乾酪乳酸桿菌(Lactobacillus paracasei)之乳酸菌,且以源自無花果之乳酸菌為宜。可具體舉如,依本發明而從無花果葉分離並鑑定之Lactobacillus paracasei IJH-SONE68菌株。該菌株係於2016年4月19日以寄存編號NITE P-02242於獨立行政法人製品評價技術基礎機構專利微生物中心(〒292-0818日本國千葉縣木更津市上總鎌足2-5-8 122號室)進行國內寄存,之後移管為遵照布達佩斯條約之國際寄存,並於2017年5月26日賦予國際寄存編號為NITE BP-02242。
Lactobacillus paracasei IJH-SONE68菌株係如圖1之照片所示,為過氧化氫酶陰性之革蘭氏陽性桿菌,且具有白色菌落形成性,並具有視條件而定之雜乳酸發酵特性的菌學性質。進一步來說,具有產生多醣體之能力。
於本發明中,與Lactobacillus paracasei IJH-SONE68株同等之乳酸菌亦視為對象。於此,同等之乳酸菌意指:屬於Lactobacillus paracasei之乳酸菌,且
與Lactobacillus paracasei IJH-SONE68菌株同樣地具有改善第IV型過敏(尤其是接觸性皮膚炎)之作用的乳酸菌。舉例來說,與其等同等之乳酸菌可藉由對Lactobacillus paracasei IJH-SONE68菌株進行突變、基因重組等一般突變處理技術來獲得,此外,也可為藉選擇Lactobacillus paracasei IJH-SONE68菌株之自然突變菌株等並育種而成之菌株。
2.本發明之有效成分
本發明之組成物包含上述乳酸菌之菌體、其培養物或發酵物或者其所產生之多醣類作為有效成分。
乳酸菌可使用一般使用之MRS培養基及其修正培養基等,藉液體靜置培養等一般使用之培養方法來培養。乳酸菌可藉由在鳳梨屬植物果汁或其萃取物存在下進行培養來促進其增殖(國際公開第WO2011/046194號),此外,在酒粕、酒粕萃取物或酒粕之酵素分解物存在下進行培養,亦可促進其增殖(日本特開平3-172171號公報、日本特開平5-15366號公報及日本專利第2835548號公報)。培養乳酸菌後,可將所得培養物直接用作有效成分,亦可將所得培養液稀釋或濃縮後使用,也可使用回收自培養物之菌體。此外,在不損及本發明效果之前提下,也可於培養後進行加熱及冷凍乾燥等各種追加操作。又,乳酸菌之菌體可為其細胞表層附著有多醣類之活菌體,亦可為死菌體,也可為活菌體及死菌體兩者。死菌體可為破碎物,但宜使多醣類附著於其表層。此外,乳酸菌之發酵物通常使用葡
萄糖等作為營養源,且可視需要進一步添加酵母萃、鳳梨屬植物果汁、酒粕、燒酒粕等植物乳酸菌之增殖促進物質並使其發酵來獲得。
乳酸菌所產生之多醣類可藉一般方法自屬於副乾酪乳酸桿菌(Lactobacillus paracasei)之乳酸菌培養物分離純化來獲得。具體舉例來說,可藉離心分離而從屬於副乾酪乳酸桿菌(Lactobacillus paracasei)之乳酸菌培養物中去除菌體,再使用乙醇及丙酮等,從所得培養物中使多醣類沉澱來獲得。此外也可藉離子交換層析法進一步進行分離純化來獲得。如此獲得之乳酸菌所產生之多醣類有中性多醣體及酸性多醣體。
本發明中乳酸菌所產生之多醣類可具體舉如:具有N-乙醯葡萄糖胺藉α-1,6鍵而連結之結構的中性多醣體,或者,主要由葡萄糖與甘露糖構成之酸性多醣體。該中性多醣體係如後述實施例2所載,可藉陰離子交換層析法將得自Lactobacillus paracasei IJH-SONE68菌株培養物之多醣體進行分離純化來製得。從圖3所示質子-NMR及碳-NMR之NMR分析圖,可明確得知該中性多醣體具有N-乙醯葡萄糖胺藉α-1,6鍵而連結之結構。此外,Lactobacillus paracasei IJH-SONE68菌株會將主要由葡萄糖與甘露糖構成之酸性多醣體分泌至菌體外。更具體來說,酸性多醣體由葡萄糖、甘露糖、半乳糖及鼠李糖構成,且其等之組成比大致上為10:170:2:1。

已殺菌之鑷子與剪刀使其細破片化至2~3mm後,於已滅菌且裝有MRS液體培養基之試管中分別裝入5~6個細片,於28℃及37℃下靜置培養至乳酸菌之標準培養基即MRS培養基發生混濁(增殖)。順帶一提,至可目視到乳酸菌候補菌株增殖為止需要2~4天。
將上述乳酸菌候補菌株之各培養液的一部分以拋棄式接種環劃線塗菌於MRS洋菜培養基上後進行靜置培養。形成於洋菜培養基上之菌落中,將「顏色、光澤、形狀不同者」全部拾取,再於新鮮之MRS洋菜培養基上進行劃線塗菌來純化菌落。
對於經純化之各菌落,為了驗證有無過氧化氫酶之產生而進行H2O2測試。此係一用以觀察菌體暴露於10% H2O2溶液時若過氧化氫酶存在即會生成氧的現象有無發生的試驗法。順帶一提,乳酸菌不會產生過氧化氫酶。
嘗試從無花果探索分離之結果,從以無花果葉作為分離源者成功獲得顯示過氧化氫酶陰性之乳酸菌候補菌株1株。
2.分離菌株之鑑定
將上述乳酸菌候補菌株另以MRS液體培養基培養並利用離心取得菌體。以細胞壁溶解酵素處理後,使用DNAzol試劑抽提出基因組DNA。
按照記載於Lane,D.J.(1991).16S/23S rRNA sequencing.In Nucleic Acid Techniques in Bacterial Systematics、pp.115-175.Edited by E.Stackebrandt &
M.Goodfellow.Chichester:Wiley之方法,以基因組DNA為模板,藉由使用27f引子與1525r引子之PCR反應,使16S rDNA部分擴增,並以NucleoSpin Gel and PCR Clean-up kit(MACHEREY-NAGEL GmbH & Co.KG製)自瓊脂糖凝膠回收目的斷片。用以決定鹼基序列之dye terminator法所致序列反應係以Big Dye Terminator Cycle Sequencing FS Ready Reaction Kit ver.3.1(ThermoFisher Scientific公司製)進行,並以ABI PRISM 3130xl Genetic Analyzer(ThermoFisher Scientific公司製)解析。以BLAST program對解析出之16S rDNA的鹼基序列進行相同性檢索,並藉由與DNA data bank(DDBJ/EMBL/GenBank)之資料庫比較,進行分離菌株之分類學鑑定。
將分離自無花果葉之乳酸菌候補菌株命名為IJH-SONE68菌株,由於其與已登記在DNA data bank(DDBJ/EMBL/GenBank)之「Lactobacillus paracasei R094」菌株且鹼基序列之accession編號為「NR_025880」的鹼基序列100%一致,而鑑定為Lactobacillus paracasei。
該菌株係於2016年4月19日以寄存編號NITE P-02242進行國內寄存於獨立行政法人製品評價技術基礎機構專利微生物中心(〒292-0818日本國千葉縣木更津市上總鎌足2-5-8 122號室),之後移管為遵照布達佩斯條約之國際寄存,並於2017年5月26日賦予國際寄存編號為
NITE BP-02242。

經分離鑑定之上述乳酸菌IJH-SONE68菌株係如圖1之照片所示,為過氧化氫酶陰性之革蘭氏陽性桿菌且具白色菌落形成性,具有視條件而定之雜乳酸發酵特性,同時具有產生多醣類之能力。
4.經分離鑑定之乳酸菌的醣類同化能力
(1)同化能力之試驗方法
藉下述試驗方法調查IJH-SONE68菌株對49種醣類之同化能力。
將IJH-SONE68菌株以MRS液體培養基靜置培養至增殖穩定期。將離心所得菌體以適量之懸浮介質(suspension medium,bioMérieux公司製)洗淨後,最後懸浮於2mL之suspension medium。將其一部分添加到5mL之suspension medium中,求出麥式(McFarland)濁度為2之量(n)。接著,於API 50 CHL培養基(bioMérieux公司製)中加入2n菌液,將其分注到API 50 CHL套組(bioMérieux公司製,各孔底分別塗附了49種醣)之各盤孔中。最後覆上礦物油層,安裝於已裝有滅菌水之托盤中。於37℃下培養48小時後,觀察各盤孔中之色調變化,藉此判定有無同化能力。
5.同化能力之試驗結果
IJH-SONE68菌株對49種醣類之同化能力調查結果係如表1所示。

將IJH-SONE68菌株以MRS液體培養基靜置培養至增殖穩定期。將該培養液5mL用作種培養液,植菌至5L之多醣體產生用半合成培養基(其組成後述)後,於37℃下靜置培養120小時。將培養液冷卻至4℃後,使培養液上清中所含蛋白質變性,為了在後續步驟中以沉澱物形式去除,添加202.5mL之100%三氯乙酸水溶液,混合後靜置30分鐘。藉離心去除沉澱物,於回收之上清液中加入等量丙酮並混合後,使其於4℃下靜置一夜,藉此使IJH-SONE68菌株所產生之多醣體沉澱。以離心回收沉澱物後,以250mL之70%乙醇進行沉澱物之洗淨。使沉澱物風乾後,添加75mL之50mM Tris-HCl緩衝液(pH 8.0)並混合1小時,藉此使沉澱物溶解。藉離心去除不溶性之夾雜物後,對所回收之上清液分別添加750μL之1mg/mL DNase溶液(Worthington公司)及1mg/mL RNase溶液(Nacalai Tesque公司),於37℃下使其反應8小時。接著,添加750μL之2mg/mL proteinase K溶液(和光純藥工業社製),於37℃下使其反應16小時。使反應後之溶液冷卻至4℃後,使所添加之各酵素變性,為了於後續之離心將其作為沉澱物去除,添加8.75mL之100%三氯乙酸水溶液並混合,於4℃下靜置1小時。以離心去除沉澱物,對所得上清液添加262.5mL之100%乙醇,確實混合後藉離心將IJH-SONE68菌株所產生之多醣類以沉澱物形式回收。以50mL之70%
乙醇洗淨沉澱物後使其風乾,添加適量(約25mL)純水並於4℃下靜置一夜,藉此使多醣類溶解。溶解後之多醣類樣本使用10,000MWCO之超過濾單元(Merck公司),一邊將溶劑替換為純水,一邊去除所回收樣本中之單醣類等小分子,而製得經純化之多醣類樣本。
將已純化之多醣類樣本施用到已預先以50mM Tris-HCl緩衝液(pH8.0)平衡化且填充有TOYOPEARL DEAE-650M樹脂(TOSOH CORPORATION)之開放管柱(2.5×22cm),進行用以分離純化中性多醣分液與酸性多醣分液之管柱作業。溶液使用相同之緩衝液,固定流速1mL/min。此外,溶出液每6mL回收到不同的試管。首先,從開始至240分鐘的期間,以相同緩衝液使其溶出(試管編號1-40)。接著,從240分鐘之時間點至600分鐘之時間點為止,製作出使用相同緩衝液之0-500mM NaCl的濃度梯度並持續溶出(試管編號41-100)。茲將管柱分離圖譜顯示於圖2。對溶出至試管之全部樣本以酚硫酸法(後述)確認多醣類之存在後,將對應試管內之溶液分別統整為中性多醣分液、酸性多醣分液。各分液使用10,000MWCO之超過濾單元,一邊將溶劑替換為純水,一邊去除所回收樣本中之單醣類等小分子。
如上述般分離純化出中性多醣分液及酸性多醣分液來作為IJH-SONE68菌株所產生之多醣類。

D組:IJH-SONE68菌株之發酵鳳梨果汁原液10倍稀釋液投予組
E組:IJH-SONE68菌株之發酵鳳梨果汁原液100倍稀釋液投予組
於此,所謂發酵鳳梨果汁原液係指,以100%
鳳梨果汁(含1w/v%燒酒蒸餾殘渣)培養IJH-SONE68菌株48小時後所得發酵液。將原液以滅菌蒸餾水稀釋10倍者為10倍稀釋液,稀釋100倍者為100倍稀釋液。

透過下述小鼠接觸性皮膚炎模式之耳殼厚變化的測定、炎症細胞激素IL-4及血清IgE位準之測定以及耳殼炎症觀察,調查IJH-SONE68菌株所產生之酸性多醣體及中性多醣體對小鼠接觸性皮膚炎模式之改善作用。
1.耳殼厚變化之測定
(1)試驗方法
動物使用雄性BALB/cA Jcl系小鼠(7週齡,CLEA Japan,Inc.:到貨時)。小鼠係以飼育籠飼養5隻,並以已調節成溫度:20~26℃、濕度:40~60%、照明時間:12小時(8:00至20:00)環境之動物飼育室飼育,食餌則使其自由攝取固體飼料MF(Oriental Yeast Co.,Ltd.)。此外,關於飲用水,則使其使自由攝取純水。
搬入小鼠後馴化7日。馴化飼育後,按下述方式分組。
A組:陰性對照組(僅一般飼料飼育組)
B組:陽性對照組(滅菌蒸餾水投予組)
C組:純化酸性EPS溶液(1mg/mL)投予組
D組:純化酸性EPS溶液(0.1mg/mL)投予組
E組:純化中性EPS溶液(1mg/mL)投予組
F組:純化中性EPS溶液(0.1mg/mL)投予組
於此,C組之酸性EPS溶液及E組之中性EPS溶液分別為實施例2所得酸性多醣分液及中性多醣分液,將其等以滅菌蒸餾水稀釋者則分別是D組之酸性EPS溶液及F組之中性EPS溶液。
令進行上述分組之時間點為Day 0,並由Day 0起以1次/日之頻率,以上述樣本對小鼠進行14日連續經口投予。另,令每天平均投予容量為0.20mL/隻。於Day 6對所有小鼠分別於兩手腳(20μL)、胸腹部(100μL)及背部(100μL)塗佈7w/v%苦基氯溶液,藉此使小鼠記憶抗原資訊。於Day 13預先以游標卡尺測定小鼠右耳殼厚度,之後在右耳殼表裏各塗佈1w/v%苦基氯溶液20μL以誘發過敏反應。24小時後(相當於Day 14)測定耳殼厚度,於各組間比較誘發前後之差異(△耳殼厚(mm))。數據係以平均值±標準誤差來表示,組間之顯著性檢定使用Tukey-Kramer法,危險率(p值)小於0.05即判定為具顯著差異。
藉上述方法評價各樣本對小鼠接觸性皮膚炎模式有無抑制作用。
(2)試驗結果
將B~F組之△耳殼厚示於表6及圖10。
由表6及圖10可知,相較於陽性對照組(B組),酸性EPS溶液投予組中無論是1mg/mL(C組)或0.1mg/mL(D組)之任一濃度,因炎症而起之耳殼厚增加已確認受到顯著抑制(分別為p<0.01及p<0.05)。此外,中性EPS溶液投予組中,1mg/mL之濃度(E組,p<0.05)可見顯著抑制,0.1mg/mL之濃度(F組)時因炎症而起之耳殼厚增加也受到抑制。上述結果顯示,藉由反復經口投予IJH-SONE68菌株產生之酸性多醣體及中性多醣體,可預防/改善苦基氯所誘導之接觸性皮膚炎模式之症狀,此種效果尤以酸性多醣體提示了高度可能性。
2.炎症細胞激素IL-4及血清IgE位準之測定
(1)試驗方法
以上述1所載試驗方法測定耳殼厚後,使小鼠安樂死,安樂死後自各組小鼠切除誘發炎症之右耳殼並予回收,再以NucleoSpin RNA Plus套組(MACHEREY-NAGEL公司製)抽提mRNA。以ReverTra Ace qPCR RT Master Mix with gDNA Remover套組(TOYOBO公司製)
從抽提出之mRNA樣本合成cDNA。以cDNA為模板,並以定量RT-PCR法比較炎症誘發部位之炎症性細胞激素IL-4之mRNA表現量。另,定量RT-PCR使用KAPA SYBR FAST qPCR Master Mix(NIPPON Genetics Co,Ltd製),並以PikoReal Real-Time PCR System裝置(Thermo Fisher Scientific公司製)進行。
此外,自安樂死後所回收之血液回收血清,以利用Mouse IgE ELISA development kit(HRP)(Mabtech公司製)之ELISA法測定血清中之IgE濃度。
各數據係以平均值±標準誤差表示,組間之顯著性檢定使用Tukey-Kramer法,危險率(p值)小於0.05即判定具顯著差異(下述圖11及12中僅就與陽性對照組之顯著差異予以記載)。
(2)試驗結果
就A~F組之IL-4之mRNA表現量(IL-4 mRNA相對於A組之相對表現量)示於表7及圖11。
由表7及圖11可知,炎症性細胞激素IL-4之mRNA轉錄因誘發炎症而在陽性對照組(B組)顯著上昇
(p<0.01),各多醣體攝取組較陽性對照組(B組)可見顯著降低(D組及E組,分別為p<0.01及p<0.05)或降低傾向(C組,p<0.1)。
茲將A~F組之血清中IgE濃度(ng/mL)示於表8,A~F組之血清中IgE濃度相對於A組之相對值示於表9,該相對值圖表化者則示於圖12。
由表8、9以及圖12可知,與IL-4時相同,陽性對照組(B組)之血清中IgE濃度顯著上昇,各多醣體攝取組(尤其C~E組)與陽性對照組相較,可見顯著降低。
上述結果顯示,藉由反復經口投予IJH-SONE68菌株產生之酸性多醣體及中性多醣體,可抑制苦基氯所誘導之接觸性皮膚炎模式小鼠之炎症性細胞激素IL-4表現及血清IgE位準上昇。
3.耳殼炎症觀察
(1)試驗方法
於測定上述1之試驗方法所載耳殼厚後,使小鼠安樂死,安樂死後自A~F組小鼠切除誘發炎症之右耳殼並予回收,以10%甲醛液固定後,包埋於石蠟並製作組織切片。切片進行hematoxylin-eosin(HE)染色,於顯微鏡下就炎症狀態進行觀察。
將結果示於圖13。由圖13可知,相較於陰性對照組(A組),陽性對照組(B組)之表皮層(EP)變薄,另一方面,真皮層(DM)則可見因炎症而厚度明顯增加之狀態。可以想見,其炎症症狀係以與投予各多醣體樣本所致耳殼厚度減少呈比例之方式受到抑制。
