Description

本発明は、ヘリコバクター・ピロリ剥離作用を有する組成物に関する。より詳細には、ホエーを加水分解することにより得られる、ヘリコバクター・ピロリ剥離作用を有する組成物に関する。   The present invention relates to a composition having a Helicobacter pylori peeling action. More specifically, the present invention relates to a composition having a Helicobacter pylori exfoliating action obtained by hydrolyzing whey.

ヘリコバクター・ピロリ(Helicobacter pylori;Hp)は、WarrenとMarshallにより胃潰瘍患者の胃から発見されて以来(非特許文献1参照)、世界的に最も感染者数の多い病原性菌の1つであることが明らかになった(非特許文献2参照)。現在では、胃炎(非特許文献3参照)、消化性潰瘍(非特許文献1及び非特許文献4参照)、胃癌(非特許文献5、非特許文献6及び非特許文献7参照)及び胃リンパ腫(非特許文献8参照)の発症に関与していることが示唆されている。 Helicobacter pylori (Helicobacter pylori; Hp) has since been found in stomach ulcer patient by Warren and Marshall (see Non-Patent Document 1), worldwide it is one of the most infected persons a large number of pathogenic bacteria Became clear (see Non-Patent Document 2). Currently, gastritis (see non-patent document 3), peptic ulcer (see non-patent document 1 and non-patent document 4), gastric cancer (see non-patent document 5, non-patent document 6 and non-patent document 7) and gastric lymphoma ( It is suggested to be involved in the onset of non-patent document 8).

Hpを除菌する治療法や医薬品の研究は盛んに行われている。現在は抗生物質投与による治療が主流である。我国でも日本ヘリコバクター学会が「H. pylori感染の診断と治療のガイドライン」を作成し、除菌治療の第一選択薬としてプロトンポンプ阻害薬(lansoprazole)と抗生物質二剤(amoxicillinおよびclarithromycin)を1週間投与する3剤併用療法を推奨している。しかしながら、副作用が14.8〜45.1%の患者で報告され、耐性菌も5〜10%の頻度で発生していることが問題点として論じられている。一方で抗生物質を用いない除菌法も研究されており、その代表としてはプロバイオティクスを用いる方法などが挙げられる(非特許文献9参照)。しかしながら、メカニズムが解明されていないため、医学的治療に応用するには至っていないのが現状である。そこで胃粘膜の構造および性状、さらに粘膜内でのHpの細菌学的特徴を考慮した除菌方法(素材)を開発することが望まれている。 Researches on therapeutic methods and medicines for eradicating Hp are actively conducted. Currently, treatment with antibiotics is the mainstream. In Japan, the Japan Helicobacter Society has prepared “Guidelines for Diagnosis and Treatment of H. pylori Infection”, and 1 proton pump inhibitor (lansoprazole) and two antibiotics (amoxicillin and clarithromycin) are the first choices for eradication Three-drug combination therapy administered weekly is recommended. However, side effects have been reported in 14.8-45.1% of patients, and it has been discussed as a problem that resistant bacteria are occurring at a frequency of 5-10%. On the other hand, sterilization methods that do not use antibiotics have also been studied, and representative examples include methods using probiotics (see Non-Patent Document 9). However, since the mechanism has not been elucidated, it has not yet been applied to medical treatment. Therefore, it is desired to develop a sterilization method (material) in consideration of the structure and properties of the gastric mucosa and the bacteriological characteristics of Hp in the mucosa.

胃粘膜は、表層ムチン層と腺ムチン層が交互に重なる多重構造をしている。表層ムチンは胃酸から胃を保護するために粘膜上皮細胞から常に分泌されるが、腺ムチンは食事摂取の際に胃底腺から胃酸やペプシンを包む形で分泌される。また、表層ムチンは、セリン、トレオニン、プロリンおよびシステインに富む1,300アミノ酸のポリペプチドを基本骨格とするMUC5AC糖タンパク質であることが知られている(非特許文献10参照)。Hpは、胃内の、主として上皮細胞近くの表層ムチン層で生育・増殖しており、新しいムチンが分泌されると押し上げられて胃内腔表面(粘膜層上層)に近づくが、その後上皮細胞側へ移動するといった動態を繰り返していると考えられている(非特許文献11参照)。Hpと胃上皮細胞やそれを覆う胃ムチンとの接着に関する研究も多く行われており、3’−シアリルラクトース(NeuAcα2−3Galβ1−4Glc;3’SL)に代表されるシアル酸を中心に(非特許文献12及び非特許文献13参照)、糖タンパク質や糖脂質の硫酸化オリゴ糖(非特許文献14及び非特許文献15参照)、さらに、基底膜構成成分であるラミニンやコラーゲン等多数が報告されている(非特許文献16参照)。   The gastric mucosa has a multi-layer structure in which the surface mucin layer and the gland mucin layer alternately overlap. Superficial mucin is always secreted from mucosal epithelial cells to protect the stomach from gastric acid, whereas glandular mucin is secreted from the fundus gland in the form of gastric acid and pepsin when ingested. The surface mucin is known to be a MUC5AC glycoprotein having a 1,300 amino acid polypeptide rich in serine, threonine, proline and cysteine as a basic skeleton (see Non-Patent Document 10). Hp grows and proliferates in the stomach, mainly in the surface mucin layer near the epithelial cells. When new mucin is secreted, it is pushed up and approaches the surface of the stomach lumen (upper layer of the mucosal layer). It is thought that the movement of moving to is repeated (see Non-Patent Document 11). Many studies have been conducted on the adhesion between Hp and gastric epithelial cells and gastric mucin covering the same, mainly sialic acid represented by 3'-sialyl lactose (NeuAcα2-3Galβ1-4Glc; 3'SL) (non- Patent Document 12 and Non-Patent Document 13), sulfated oligosaccharides of glycoproteins and glycolipids (see Non-Patent Document 14 and Non-Patent Document 15), and a large number of laminin and collagen as basement membrane constituents have been reported. (See Non-Patent Document 16).

こうした知見を利用して、in vitroにおける上皮細胞(モデル)や胃ムチンへのHp接着抑制作用が、上記の物質(非特許文献17参照)に加えクランベリージュース(非特許文献18及び非特許文献19参照)や牛乳由来の糖タンパク質(非特許文献20参照)などについて報告されている。これらの結果は、Hpと阻害物質を同時に添加して凝集反応を調べるか、プレートに固定化した細胞あるいはムチンに菌体懸濁液と同時に阻害物質を混入して得られたものである(非特許文献20及び非特許文献19参照)。しかしながら、Hp凝集/接着抑制作用があっても、Hp保菌者に対して投与する場合、実際に除菌効果が得られるか不明である。胃ムチンからのHp剥離作用を調べている報告は殆どなく、クランベリージュースを用いた報告(非特許文献18参照)では、Hp接着抑制作用が認められた高分子非透析画分にHp剥離作用が無かったと示されている。   Utilizing such knowledge, in vitro Hp adhesion inhibitory action on epithelial cells (model) and gastric mucin is added to the above substances (see Non-Patent Document 17) and cranberry juice (Non-Patent Document 18 and Non-Patent Document 19). Reference) and milk-derived glycoproteins (see Non-Patent Document 20). These results were obtained by simultaneously adding Hp and an inhibitor and examining the agglutination reaction, or by mixing an inhibitor with cells or mucin immobilized on a plate at the same time as the cell suspension (non-) (See Patent Literature 20 and Non-Patent Literature 19). However, even if there is an Hp aggregation / adhesion inhibitory effect, it is unclear if the sterilization effect is actually obtained when administered to Hp carriers. There are almost no reports investigating Hp peeling action from gastric mucin, and in the report using cranberry juice (see Non-Patent Document 18), the Hp peeling action is observed in the polymer non-dialysis fraction in which Hp adhesion inhibitory action was observed. It is shown that there was no.

さらに、ピロリに対する感染阻止効果に関し、乳汁由来のムチンに定着阻害効果があることが開示されている(特許文献1参照)。しかしながら、記載されている方法は乳脂肪及びカゼイン、さらにはリポ蛋白を除去した後、セファロースカラムで乳汁由来のムチンを分離するものである。また、乳汁由来のムチンの原料としてチーズ等の製造工程で副産物として大量に出るホエーが利用可能であり、価格的にも実用的にも有利であることが記載されているが、乳汁由来のムチンはその調整方法が煩雑なことに加えて乳汁中の含量が極めて少なく(特許文献1において0.01%の収量)、高価な素材となることが予想され、採算性及び実現性には問題がある。   Furthermore, regarding the infection prevention effect against H. pylori, it has been disclosed that mucin derived from milk has an inhibitory effect on colonization (see Patent Document 1). However, the described method is to separate milk-derived mucin on a Sepharose column after removing milk fat and casein, as well as lipoproteins. In addition, it is described that whey that is produced in large quantities as a by-product in the production process of cheese or the like can be used as a raw material for milk-derived mucin, which is advantageous in terms of price and practicality. In addition to its complicated adjustment method, the content in milk is extremely small (0.01% yield in Patent Document 1) and is expected to be an expensive material, and there are problems in profitability and feasibility. is there.

これまで発明者らは、原材料としてバターミルク(即ち、牛乳から分離したクリームを原料とし、バター製造のチャーニング工程中に脂肪塊と分離されて生じる液体)をプロテアーゼ処理することでシアル酸量に関係なく、Hpとの接着性や剥離活性が著しく上昇することを報告している(非特許文献25)。すなわち、プロテアーゼ処理でタンパク質の立体構造を変化させることにより、シアル酸を中心とした糖鎖部位以外にもHpに対して強い親和性を有するペプチドが形成されることを示している。   So far, the inventors have increased the amount of sialic acid by protease treatment of buttermilk (ie, a liquid produced by separating cream from milk and separated from fat mass during the buttering churn process) as a raw material. Regardless, it has been reported that adhesion to Hp and peeling activity are significantly increased (Non-patent Document 25). That is, it is shown that a peptide having a strong affinity for Hp is formed in addition to the sugar chain site centering on sialic acid by changing the three-dimensional structure of the protein by protease treatment.

ホエーはチーズ製造時に多量に生じ、我が国では年間約32万トン(2002年度)が排出されている。ホエーを有効利用する研究も進み、最近では機能性食品素材として様々な用途に使用されつつあるが、その大部分が産業廃棄物として処分されているのが現状である。   Whey is produced in large quantities during cheese manufacture, and approximately 320,000 tons (fiscal year 2002) are discharged annually in Japan. Research on the effective use of whey has also progressed, and recently it has been used as a functional food material for various purposes, but most of it is disposed of as industrial waste.

本発明は、シアル酸が含まれている乳汁ムチン成分とは関わりなく、全ホエータンパク質を単純にプロテアーゼ処理することで、シアル酸を介さずにHpと接着し、さらに胃ムチンに定着したHpを剥離する作用を有する安全で安価な組成物を提供することを可能にする。   In the present invention, regardless of the milk mucin component containing sialic acid, the whole whey protein is simply treated with protease to adhere to Hp without sialic acid, and further to fix Hp fixed on gastric mucin. It makes it possible to provide a safe and inexpensive composition having a peeling action.

結果
生乳、クリームチーズ及びカッテージチーズ由来のホエー分解物のHp剥離活性を表2に示す。全てのホエーが未処理では活性が無かったのに対し、パンクレアチン又はパパインで加水分解を行うことにより剥離活性を発揮することが判明した。この活性はバターミルク分解物と比較すると劣るものの、乳汁ムチン(特許文献1)とほぼ同等で、カッテージチーズホエー分解物に関しては大きく上回っていた。以上の結果は、ホエー分解物を予防目的以外に治療目的でも使用できる可能性を示している。
Results Table 2 shows the Hp peeling activity of whey degradation products derived from raw milk, cream cheese and cottage cheese. It was found that all whey had no activity when untreated, but exerted peeling activity by hydrolysis with pancreatin or papain. Although this activity was inferior to the buttermilk degradation product, it was almost equivalent to the milk mucin (Patent Document 1) and greatly exceeded the cottage cheese whey degradation product. The above results indicate the possibility that the whey degradation product can be used not only for preventive purposes but also for therapeutic purposes.

性状分析
実施例1および2で、ホエー分解物にHpに対する強力な接着作用及び剥離作用が確認されたが、既にピロリに対し定着阻害作用を示す類似物質として、乳汁ムチンが報告されている(特許文献1参照)。本実施例ではホエー分解物、乳汁ムチン及びバターミルク分解物との違いを明確にするため、以下の試験検討を行った。
Property analysis In Examples 1 and 2, the whey degradation product was confirmed to have a strong adhesive action and exfoliating action against Hp, but milk mucin has already been reported as a similar substance showing an inhibitory action against H. pylori (patent) Reference 1). In this example, the following examination was conducted in order to clarify the difference from the whey degradation product, milk mucin and buttermilk degradation product.

材料および方法
(1)ホエー加水分解物
生乳、クリームチーズホエー及びカッテージチーズホエーから、実施例1と同様の方法でホエー分解物を調製した。性状分析に用いたホエーは実施例1で活性の強かったパパイン及びパンクレアチン処理物である。乳汁ムチンは特許文献1に、バターミルク分解物は非特許文献25にしたがい調製した。
Materials and Methods (1) Whey hydrolyzate A whey hydrolyzate was prepared from raw milk, cream cheese whey and cottage cheese whey in the same manner as in Example 1. The whey used for the characterization was the papain and pancreatin treated product that was highly active in Example 1. The milk mucin was prepared according to Patent Document 1 and the buttermilk degradation product was prepared according to Non-Patent Document 25.

(2)試験方法
ホエー分解物のタンパク質及び糖質の含有量、分子量分布を、ケルダール法、フェノール硫酸法、及びゲルろ過法でそれぞれ測定し、特許文献1に記載の乳汁ムチン及び非特許文献25に記載のバターミルク分解物の成分組成及び分子量と比較した。また、SDSポリアクリルアミドゲル電気泳動(SDS−PAGE)後に銀染色を行い、ペプチドパターンを比較した(図2A)。さらに、SDS−PAGE後にウエスタンブロット法にて膜転写し、ペルオキシダーゼ標識小麦胚芽レクチンと反応させ、糖鎖パターンを比較した(図2B)。
(2) Test method The protein and carbohydrate content and molecular weight distribution of the whey degradation product were measured by the Kjeldahl method, the phenol sulfate method, and the gel filtration method, respectively. The milk mucin described in Patent Literature 1 and Non-Patent Literature 25 And compared with the component composition and molecular weight of the buttermilk degradation product described in 1. Moreover, silver staining was performed after SDS polyacrylamide gel electrophoresis (SDS-PAGE), and the peptide patterns were compared (FIG. 2A). Furthermore, after SDS-PAGE, the membrane was transferred by Western blotting, reacted with peroxidase-labeled wheat germ lectin, and the sugar chain patterns were compared (FIG. 2B).

結果
表3に示すように、ホエー分解物は乳汁ムチンと比較してタンパク質含量が高く、糖質が少ないことが確認された。一方、バターミルク分解物と比較したところ、タンパク質含量が低く、糖質含量が高いことが認められた。また、乳汁ムチン及びバターミルク分解物とは分子量が大きく異なることが確認された(図2A)。
Results As shown in Table 3, it was confirmed that the whey degradation product had a higher protein content and less carbohydrates than milk mucin. On the other hand, when compared with the buttermilk degradation product, it was confirmed that the protein content was low and the sugar content was high. Moreover, it was confirmed that the molecular weight is significantly different from the milk mucin and the buttermilk degradation product (FIG. 2A).

さらに、ペプチドパターン及び糖鎖パターンが、ホエー分解物及びバターミルク分解物とは明らかに相違し、これらは異なる物質であることが確認された。特に、バターミルク分解物はレクチン反応の結果から糖鎖を含んでいることが確認されたのに対し、ホエー分解物は含んでいなかった(図2B)。   Furthermore, the peptide pattern and sugar chain pattern were clearly different from the whey degradation product and the buttermilk degradation product, and it was confirmed that these were different substances. In particular, the buttermilk degradation product was confirmed to contain sugar chains from the results of the lectin reaction, whereas it did not contain whey degradation product (FIG. 2B).

以上より、ホエー加水分解物が強いHp接着性ならびに剥離活性を有することは明らかである。このホエー分解物中に含まれるポリペプチドは、乳汁ムチンなどの既存の抗ピロリ食品素材と比較して、剥離活性はもとより、生産性、熱安定性が高いことから、大量生産および長期保存が可能な機能性素材として大いに期待できる。   From the above, it is clear that the whey hydrolyzate has strong Hp adhesion and peeling activity. Polypeptides contained in this whey degradation product can be mass-produced and stored for a long period of time due to their high productivity and thermal stability as well as exfoliation activity compared to existing anti-pylori food materials such as milk mucin. It can be greatly expected as a functional material.
