Description

本発明は関節リウマチの治療剤組成物に関し、さらに詳しくは抗リウマチ作用を有する抗体を含有する関節リウマチの治療・予防効果を有する組成物に関する。   The present invention relates to a therapeutic composition for rheumatoid arthritis, and more particularly to a composition having an effect of treating or preventing rheumatoid arthritis, comprising an antibody having an anti-rheumatic action.

関節リウマチは手や足の関節の発赤、疼痛、腫れ、に始まり、関節の破壊、変形に進み、痛みとともに関節の機能麻痺に至る炎症性の関節の疾患である。その薬物療法には炎症を止めるために、副腎皮質ホルモン剤、免疫抑制剤、酸性抗炎症剤、有機金化合物、抗サイトカイン抗体その他の薬剤の組み合わせによる治療が行われている。これらの薬物療法はいずれも所謂、対症療法である。   Rheumatoid arthritis is an inflammatory joint disease that begins with redness, pain and swelling of the joints of the hands and feet, progresses to destruction and deformation of the joints, and leads to functional paralysis of the joints with pain. In the drug therapy, in order to stop inflammation, treatment with a combination of corticosteroids, immunosuppressants, acidic anti-inflammatory agents, organic gold compounds, anti-cytokine antibodies, and other drugs is performed. These drug therapies are so-called symptomatic treatments.

関節リウマチの病因は今日、一般的には不明とされているが、関節軟骨の主成分であるII型コラーゲンに対する自己免疫が関係するという学説に基づく研究がなされている。   The etiology of rheumatoid arthritis is generally unknown today, but studies based on the theory that autoimmunity to type II collagen, the main component of articular cartilage, is involved.

食事中には、多くの抗原物質があるが、通常、経口摂取では、これらの抗原にたいする抗体産生が起こらない。この現象は経口免疫寛容と称される。   There are many antigenic substances in the diet, but antibody production against these antigens usually does not occur when taken orally. This phenomenon is called oral tolerance.

抗体産生は、抗体産生の促進に働くリンパ球(ヘルパーT細胞、Th)と、抑制的に働くリンパ球(サプレッサーT細胞、Ts)により調節されている。サプレッサーT細胞が優位な状態では抗体産生は抑制されることから、II型コラーゲンに対する自己抗体の産生を抑制するために、II型コラーゲンに対するサプレッサーT細胞を賦活する意図で、動物由来のII型コラーゲン由来のペプチド、II型コラーゲンの変性物を投与する試みがなされている。この例として、例えば特許文献1〜3が挙げられ、これらはいずれも経口免疫寛容を意図した特許である。   Antibody production is regulated by lymphocytes (helper T cells, Th) that work to promote antibody production and suppressive lymphocytes (suppressor T cells, Ts). Since antibody production is suppressed when suppressor T cells are dominant, animal-derived type II collagen is intended to activate suppressor T cells against type II collagen in order to suppress autoantibody production against type II collagen. Attempts have been made to administer a modified peptide derived from type II collagen. Examples of this include Patent Documents 1 to 3, which are all patents intended for oral tolerance.

本発明者らは、関節リウマチの予防・治療に資するため、病因の解明をおこなってきた。関節リウマチの病因は、内的要因として、患者の体質的、遺伝的要因として、関節リウマチ患者では経口免疫の破綻があること、外的要因として、食物中の異種動物由来のII型コラーゲン、および、細菌内毒素の消化管からの吸収が原因となっているという仮説のもとに研究を開始した。   In order to contribute to the prevention and treatment of rheumatoid arthritis, the present inventors have elucidated the etiology. The etiology of rheumatoid arthritis is an internal factor, a constitutional and genetic factor of the patient, a breakdown of oral immunity in patients with rheumatoid arthritis, an external factor such as type II collagen derived from different animals in food, and The research started under the hypothesis that bacterial endotoxin absorption is caused by the digestive tract.

経口免疫の破綻とは以下の状態である。経口摂取された抗原に対しては、経口免疫寛容が正常の免疫応答であるが、内因的、体質的、環境的要因により、正常な免疫寛容を誘導し得なくなり、自己抗体を産生するにいたるという考えである。この仮説の検証のために、マウスにおけるコラーゲン関節炎に関して、類似抗原および細菌内毒素の関節炎誘発活性について、マウスを用いて検討した。DBA/1系マウスはII型コラーゲン関節炎を容易に発症する遺伝形質を有するマウスである。このマウスにニワトリ由来II型コラーゲン、あるいは熱変性させたものを経口的に与えると、マウスの血液中にはマウスのII型コラーゲンに対する抗体が産生されるとともに、関節炎が発症した。この関節炎は細菌内毒素(別称リポポリサッカライドまたはLPS)の併用で増悪した。またニワトリ由来II型コラーゲンを除いた、細菌内毒素のみの長期投与でも関節炎を発症した(非特許文献1)。   The breakdown of oral immunity is as follows. Oral tolerance is a normal immune response to antigens taken orally, but due to intrinsic, constitutional, and environmental factors, normal tolerance cannot be induced and autoantibodies are produced. This is the idea. For the verification of this hypothesis, the arthritis-inducing activity of similar antigens and bacterial endotoxins was examined using mice for collagen arthritis in mice. A DBA / 1 mouse is a mouse having a genetic trait that easily develops type II collagen arthritis. When these mice were orally given chicken-derived type II collagen or heat-denatured, antibodies against mouse type II collagen were produced in the blood of the mice and arthritis developed. This arthritis was exacerbated by the combination of bacterial endotoxin (also known as lipopolysaccharide or LPS). Arthritis also developed after long-term administration of bacterial endotoxin alone, excluding chicken-derived type II collagen (Non-patent Document 1).

これらの結果はII型コラーゲンに対する抗体とともに、細菌内毒素による免疫系の非特異的賦活ないし疲弊が関節リウマチの発症に関与すること、さらに、経口免疫寛容が正立しない場合のあることを示している。この実験においては、前記特許文献1〜3で示された、免疫寛容を意図して調整した熱変性II型コラーゲンについても免疫寛容を誘導できないことがあることが示された。

These results, together with antibodies to type II collagen, indicate that nonspecific activation or exhaustion of the immune system by bacterial endotoxins is involved in the development of rheumatoid arthritis, and that oral tolerance may not be upright. Yes. In this experiment, it was shown that heat tolerance could not be induced even for heat-denatured type II collagen prepared for the purpose of immune tolerance shown in Patent Documents 1 to 3 described above.

本発明の課題は、関節リウマチの予防・治療および再発予防機能を有する組成物を提供することである。   An object of the present invention is to provide a composition having a function of preventing and treating rheumatoid arthritis and preventing recurrence.

本発明者らは、前記課題を解決するために鋭意検討した結果、II型コラーゲン、グラム陰性腸内細菌死菌体の各々またはこれらの混合物をワクチンとしてウシ、ヤギ、羊、鶏を免疫し、抗体を産生させ、その抗体を、ウシ、ヤギ、羊の場合は乳として分泌させ、鶏は鶏卵黄抗体として分泌させ、それらの抗体を、食品または医薬品の組成物とすることにより、課題を達成できることを見出し、本発明に到達した。すなわち、それらの抗体を含有する食品または医薬品を摂取することにより、食品由来のII型コラーゲン、口腔や腸内において細菌によって産生される内毒素を、各々に対応する抗体と反応させることにより不活性化ないしは消化管からの吸収を防止できること、その結果として、関節リウマチを予防し、ないしは病態を改善し治療に役立つことを見出し、本発明に到達した。   As a result of intensive studies to solve the above problems, the present inventors immunized cattle, goats, sheep, and chickens with vaccines each of type II collagen, gram-negative enterobacterial bacterial cells, or a mixture thereof, In the case of cows, goats and sheep, the antibody is produced and secreted as milk, and the chicken is secreted as chicken egg yolk antibody. These antibodies are used as food or pharmaceutical compositions to achieve the task. We have found out that we can do it and have reached the present invention. In other words, by ingesting foods or medicines containing these antibodies, it is inactive by reacting food-derived type II collagen, endotoxins produced by bacteria in the oral cavity or intestine with the corresponding antibodies. It has been found that it is possible to prevent absorption from the gastrointestinal tract or gastrointestinal tract and, as a result, prevent rheumatoid arthritis, or improve the pathological condition and be useful for treatment.

The antibody obtained after separation from blood is used as a composition for food or medicine. Each item will be described below.

1.免疫に用いる抗原
本発明においては、抗原として動物のII型コラーゲンおよびグラム陰性細菌もしくはその内毒素(LPS)を好ましく使用する。
1)ウシ、ブタ、およびニワトリのII型コラーゲンは市販品(Chondrex社)を用いることができる。抗原は単独でも混合でも良いが、ニワトリ、ウシ、ブタ、のII型コラーゲンを任意の組み合わせで混合した混合ワクチンが効率的かつ経済的である。
1. Antigen used for immunization In the present invention, animal type II collagen and Gram-negative bacteria or endotoxin (LPS) thereof are preferably used as antigens.
1) Commercially available products (Chondrex) can be used for type II collagen of bovine, porcine, and chicken. Antigens may be used alone or in combination, but a mixed vaccine prepared by mixing chicken, bovine, porcine type II collagen in any combination is efficient and economical.

2)細菌内毒素に対する抗体を産生させるために免疫に用いる抗原としては、人体寄生性グラム陰性細菌で、以下に示す属に該当する細菌である。 すなわち、フソバクテリム(Fusobacterium), ベイヨネラ(Veillonella), メガスフェラ(Megasphaera),ナイセリア(Neisseria), モラクセラ(Moraxella), ブランハメラ(Branhamella), アシネトバクター(Acinetobacter), シトロバクター(Citrobacter), エンテロバクター(Enterobacter), 大腸菌(Escherichia), ハフニア(Hafnia),クレブシエラ(Klebsiella), モルガネラ)(Morganella), プロテウス(Proteus), プロビデンシア(Providencia), サルモネラ(Salmonella), セラチア(Serratia), シゲラ(Shigella), エルシニア(Yersinia), ビブリオ(Vibrio), エロモナス(Aeromonas), プレジオモナス(Plesiomonas), ヘモフィルス(Haemophillus), パスツレラ(Pasteurella), 緑膿菌(Pseudomonas), レジオネラ(Legionella)などのホルマリン処理ないし加熱死菌を死菌ワクチンとする。ワクチンは単独でも混合ワクチンでもよいが、混合ワクチンが効率的である。菌の培養は成書に記載された通常の方法でよい。 2) Antigens used for immunization to produce antibodies against bacterial endotoxins are human parasitic Gram-negative bacteria that fall into the genus shown below. That is, Fusobacterium, Veillonella, Megasphaera, Neisseria, Moraxella, Branhamella, Acinetobacter, Citrobacter, enterobacter Enterobacter (Escherichia), Hafnia, Klebsiella, Morganella, Proteus, Providencia, Salmonella, Serratia, Shigella, Yia Formalin-treated or heat-killed bacteria such as Vibrio, Aeromonas, Prelesiomonas, Haemophillus, Pasteurella, Pseudomonas, Legionella, etc. To do. The vaccine may be a single vaccine or a mixed vaccine, but a mixed vaccine is efficient. The culturing of the fungi may be performed by the usual method described in the book.

3)動物は微生物と共生しており、各動物種の消化管には各動物固有の微生物とともに、ヒトと共通の微生物も生存し、これらが抗原となって動物は抗体を産生し,保有する。これらは自然抗体と称される。ヒトと共通のグラム陰性菌の内毒素に対する抗体も、自然抗体として存在するので、これらを用いることもできる。 3) Animals live in symbiosis with microorganisms, and in the digestive tract of each animal species, microorganisms common to humans and microorganisms common to humans survive, and these animals become antigens and animals produce and possess antibodies. . These are called natural antibodies. Since antibodies against gram-negative bacterial endotoxins common with humans also exist as natural antibodies, these can also be used.

2.動物の選択
通常、自己ないし同種の抗原に対しては、それを注射しても動物は抗体を産生しないことが知られている。さらに、産生された抗体の量は、抗原と免疫される動物種の異種性の隔たりが大きいほど多くなる傾向がある。したがって、例えば、ウシII型コラーゲンに対する抗体の作成はウシII型コラーゲンを鶏に免疫し、鶏卵卵黄抗体として回収することが望ましい。また、ニワトリII型コラーゲンに対する抗体の作成はニワトリII型コラーゲンを牛に免疫して、抗体を乳汁または血清中に得ることができる。このように、II型コラーゲンで免疫される動物は異種由来のII型コラーゲンを接種する。異種由来であれば複数のコラーゲンを混合して混合ワクチンとして注射することが効率的、かつ経済的である。
細菌成分はすべての動物にとって抗原性を持つので、これらをワクチンとして、混合して免疫注射することができる。
2. Selection of animals It is generally known that an animal does not produce an antibody against an autologous or cognate antigen when injected. Furthermore, the amount of antibody produced tends to increase as the heterogeneous distance between the animal species immunized with the antigen increases. Therefore, for example, for the production of antibodies against bovine type II collagen, it is desirable to immunize chickens with bovine type II collagen and recover them as chicken egg yolk antibodies. In addition, an antibody against chicken type II collagen can be obtained by immunizing a cow with chicken type II collagen and obtaining the antibody in milk or serum. Thus, animals immunized with type II collagen are inoculated with heterologous type II collagen. If it is derived from different species, it is efficient and economical to mix a plurality of collagens and inject them as a mixed vaccine.
Since bacterial components are antigenic for all animals, they can be mixed and injected as a vaccine.

3.抗原接種方法
動物即ち乳牛および乳山羊、羊、鶏への摂取方法は、いずれの抗原も水溶液ないし懸濁液のままでもよいが、コラーゲンのように蛋白質性の抗原には各種免疫アジュバントと混合して投与することが望ましい。一回の免疫には蛋白乾燥重量10?1000μグラムを0.1?10ml に溶解ないし懸濁し、等容量のフロインドの完全アジュバントおよび不完全アジュバント、TiterMax Gold または Ribi Adjuvant R-730 などを用いて油中水型エマルジョンとして、皮内、皮下、筋肉内1箇所ないし10箇所に分けて、一箇所0.1?10mlを注射する。これを週1回ないし2月に1回行う。
3. Antigen inoculation method Animals, such as cows and dairy goats, sheep, and chickens, can be in the form of an aqueous solution or suspension. However, proteinaceous antigens such as collagen can be mixed with various immune adjuvants. Is desirable. For a single immunization, dissolve 10-1000 μg of protein dry weight in 0.1-10 ml and suspend in 0.1-10 ml and use an equal volume of Freund's complete and incomplete adjuvants such as TiterMax Gold or Ribi Adjuvant R-730. As a mold emulsion, inject into 0.1 to 10 ml at one site, divided into 1 to 10 sites, intradermal, subcutaneous and intramuscular. Do this once a week or once in February.

内毒素に体する抗体の作成には、0.01%?10%湿重量の一種の死菌液ないし複数の死菌液の混合物の0.1?10 mlを皮下、筋肉内、皮下ないし静脈内に1?4週に1回投与する。内毒素に体する抗体の作成をアジュバントと共に免疫して行うことも可能である。死菌液にフロインドの完全アジュバントおよび不完全アジュバント、TiterMax Gold または Ribi Adjuvant R-730 などを用いて油中水型エマルジョンとして、皮内、皮下、筋肉内1箇所ないし10箇所に分けて注射する。これを週1回ないし2月に1回行う。   For the production of antibodies against endotoxin, 0.1 to 10 ml of a mixture of one type of killed bacteria or a mixture of several killed bacteria of 0.01% to 10% wet weight is given subcutaneously, intramuscularly, subcutaneously or intravenously. Administer once every 4 weeks. It is also possible to immunize with an adjuvant to produce antibodies against endotoxins. The dead bacteria solution is injected as a water-in-oil emulsion using Freund's complete and incomplete adjuvants, such as TiterMax Gold or Ribi Adjuvant R-730, divided into 1 to 10 sites intradermally, subcutaneously, or intramuscularly. Do this once a week or once in February.

4.抗体の採取
1)乳汁抗体の採取
搾乳は通常の方法により手または搾乳機を用いて行う。
抗体は72℃を超える加熱で活性を失うため、最終製品まで過剰な加熱を避ける。生乳の殺菌は72℃以下での処理、紫外線照射殺菌または放射線照射殺菌が適当である。乳汁は遠心分離により、脂肪を除き、噴霧乾燥し、スキムミルクとしたもの、脂肪を除いた後、塩酸を加えてpH4.6とし、析出するカゼインをろ過除去し、さらに乳糖、ミネラルなどの低分子成分を限外ろ過により除いてホエーとしたもの、さらに限外ろ過によりラクトアルブミン、ラクトグロブリンをのぞき抗体蛋白を主とする分画などを、低温噴霧乾燥、または凍結乾燥し、抗体含有量0.1%台から約90%含有する粉末状の抗体組成物とすることができる。通常初乳を除く牛生乳1トンから総抗体として10〜100g、平均30gが得られる。また、抗体を含有する、市販のホエー、乳清タンパク濃縮物(WPC)、乳清タンパク分離物(WPI)を用いることもできる。
4). Antibody collection 1) Milk antibody collection Milking is carried out by hand or using a milking machine in the usual manner.
Since antibodies lose activity upon heating above 72 ° C., avoid excessive heating to the final product. For sterilization of raw milk, treatment at 72 ° C. or lower, ultraviolet irradiation sterilization or radiation irradiation sterilization are suitable. Milk is centrifuged to remove fat, spray dried to skim milk, fat is removed, hydrochloric acid is added to pH 4.6, precipitated casein is removed by filtration, and low molecular weight substances such as lactose and minerals are added. Components obtained by removing the components by ultrafiltration to make whey, and fractions mainly consisting of antibody proteins excluding lactalbumin and lactoglobulin by ultrafiltration are cryospray-dried or freeze-dried, and the antibody content is 0.1%. It can be set as the powdery antibody composition containing about 90% from a stand. Usually, 1 to 100 g of total antibody is obtained from 1 ton of raw cow milk excluding colostrum, and an average of 30 g. Commercially available whey, whey protein concentrate (WPC), and whey protein isolate (WPI) containing antibodies can also be used.

2)血清抗体の採取
免疫動物の血液は抗体含量が高く、原料として優れる。
採取した血液を遠心分離して血清とした後、硫安1/3飽和で沈殿するガンマグロブリン画分をろ過採取し、水に溶解後、脱塩し、低温噴霧乾燥ないし凍結乾燥し粉末とする。通常抗体含有量は70〜90%で、血液1kgから、総抗体約15gが得られる。
2) Collection of serum antibodies The blood of immunized animals has a high antibody content and is excellent as a raw material.
The collected blood is centrifuged to obtain serum, and then the gamma globulin fraction that precipitates at 1/3 saturation of ammonium sulfate is collected by filtration, dissolved in water, desalted, and low-temperature spray-dried or freeze-dried to obtain a powder. Usually, the antibody content is 70 to 90%, and about 15 g of total antibody is obtained from 1 kg of blood.

3)鶏卵抗体の採取
免疫鶏卵の卵黄よりGITキット〔コスモバイオ(株)〕を用いて、一般に鶏卵1kgより純度90%のIgY抗体0.9〜1.5gが得られる。抗体溶液は低温噴霧乾燥ないし凍結乾燥し粉末とする。
3) Collection of chicken egg antibody From the egg yolk of immunized chicken egg, 0.9 to 1.5 g of 90% pure IgY antibody is generally obtained from 1 kg of chicken egg using GIT kit [Cosmo Bio Co., Ltd.]. The antibody solution is powdered by low temperature spray drying or freeze drying.

5.抗体の定量法
抗体の量については、抗体の抗原特異性とは関係なく、総抗体量を測定する方法と、各抗原に対する抗体の量の測定法としてELISA法(Fujii K, et al. J Immunol Methods 1989;124:63-70)による測定方法の両者が用いられる。
5. Antibody quantification method The amount of antibody is independent of the antigen specificity of the antibody, and the total antibody amount is measured, and the ELISA method (Fujii K, et al. J Immunol Both measurement methods according to Methods 1989; 124: 63-70) are used.

1)総抗体量の測定
プロテインGカラムは、抗体を効率よく精製するための抗体精製用アフィニテイカラムとして市販されている(アマシャム バイオサイエンス、その他)。抗体を含む溶液を中性付近のpHで通過させると、抗体を100%近く吸着することが出来る。カラムを洗浄後、pHを2.5〜2.8の酸性溶液を流すと、抗体はカラムから遊離し回収される。抗体1%溶液の紫外部波長280nmにおける吸光度は種差に共通で約14であるので、吸光度から抗体の量を求める。
1) Measurement of total antibody amount Protein G columns are commercially available as antibody purification affinity columns for efficiently purifying antibodies (Amersham Biosciences, etc.). When a solution containing an antibody is passed at a pH near neutral, the antibody can be adsorbed by nearly 100%. After washing the column, when an acidic solution having a pH of 2.5 to 2.8 is passed, the antibody is released from the column and collected. Since the absorbance at an ultraviolet wavelength of 280 nm of the antibody 1% solution is about 14 in common with the species difference, the amount of antibody is determined from the absorbance.

2)総IgYの測定
市販の卵黄抗体の吸着カラム(HiTrapIgYPurificationHP,アマシャム バイオサイエンス)を用い、容易に定量することができる。抗体含有液を0.5M硫酸カリウム含有20mMリン酸緩衝溶液pH7.5で吸着させ、同液で洗浄後、20mMリン酸緩衝溶液pH7.5で溶出し、回収したIgY抗体を吸光度より算出する。
2) Measurement of total IgY A commercially available egg yolk antibody adsorption column (HiTrapIgYPurificationHP, Amersham Bioscience) can be easily quantified. The antibody-containing solution is adsorbed with 0.5 M potassium sulfate-containing 20 mM phosphate buffer solution pH 7.5, washed with the same solution, eluted with 20 mM phosphate buffer solution pH 7.5, and the collected IgY antibody is calculated from the absorbance.

3)アフィニテイ精製特異抗体のELISA法による測定
コラーゲンおよび細菌内毒素(LPS)をアクテイゲル(ステロジーン)やCNBr活性化(セファロースアマシャム バイオサイエン)に共有結合させ、抗体精製用の抗原アフィニテイカラムとして用いる。精製する抗体溶液をカラムに流し、目的とする抗体のみカラムに吸着させ、カラムに吸着しない免疫グロブリンなどを中性バッファーで洗い出した。カラムに結合した抗体はpH2.8の0.1Mグリシン緩衝液で溶出した。溶出抗体をさらにプロテインGカラムによりかけ、精製した抗体を標準品としてELISA(酵素免疫測定法)により検量線を作成し、定量した。各抗原によるウエルの感作条件、ブロッキング溶液を以下に記載する。
3) Measurement of affinity-purified specific antibody by ELISA method Collagen and bacterial endotoxin (LPS) are covalently bound to Actigel (Steligen) or CNBr activation (Sepharose Amersham Biosciencen) and used as an antigen affinity column for antibody purification. The antibody solution to be purified was allowed to flow through the column, only the target antibody was adsorbed to the column, and immunoglobulins that were not adsorbed on the column were washed out with a neutral buffer. The antibody bound to the column was eluted with 0.1 M glycine buffer at pH 2.8.

Inhibitory effect of anti-collagen antibody and anti-LPS antibody against the onset of arthritis in mice by long-term oral administration of chicken type II collagen and LPS When LPS is added to chicken type II collagen and orally administered to mice, antibody production is produced compared to the group administered with type II collagen alone And the onset of arthritis is enhanced (K. Terato et al. Br. J. Rheum. 35,828-838, 1996). Thus, the arthritis inhibitory action of each antibody was examined using DBA / 1 mice. Arthritis-prone DBA / 1 male 6-week-old mice consisted of 6 mice per group, collagen (chicken II collagen chondrox) alone group, and LPS (E.coli O-111: B4 Sigma) added to collagen A group and a group to which an anti-collagen antibody (Example 3) and an anti-LPS antibody (Example 2) are further added and administered are set, and 4 courses of oral immunization with 2 weeks as 1 course over 14 weeks Went. In oral administration during the oral immunization period, in order to promote oral absorption of collagen and LPS, 40 μg of indomethacin was added to all groups including Control Group 1, and a total volume of 0.4 ml was orally administered. On the first day of 16 weeks, blood was collected from the fundus and serum was obtained. Then, LPS was orally administered for the purpose of developing arthritis for one week. On the first day of each immunization course and on the first day of the 17th week, the swelling of the joint was scored (documents described in Table 2) and scored. Table 2 shows the composition of the animal group, treatment conditions, and footpad volume. All doses are orally administered per mouse.
