Description

本発明は、ヒアルロニダーゼを有効成分とする自己免疫疾患治療剤、炎症治療剤及び神経疾患治療剤に関する。また、本発明は、ヒアルロニダーゼを有効成分とする自己免疫疾患予防剤、炎症予防剤及び神経疾患予防剤に関する。   The present invention relates to a therapeutic agent for autoimmune diseases, a therapeutic agent for inflammation and a therapeutic agent for neurological diseases, which comprises hyaluronidase as an active ingredient. The present invention also relates to an autoimmune disease preventive agent, inflammation preventive agent and neurological disease preventive agent comprising hyaluronidase as an active ingredient.

多発性硬化症(multiple sclerosis : MS)は、寛解と再発きたすヒトの中枢神経系の自己免疫疾患であり、炎症に伴って中枢神経系の髄鞘のみが崩壊する代表的な脱髄性疾患と知られている。MSは、多くは思春期から40歳代のあいだに発症し、歩くとふらつく、目がかすむ、二重に見える、尿が出にくい、および痛みやしびれなどの症状がある。子供や若い人が発症する場合には、てんかんが出ることもある。症状を現す原因となる病巣が大脳や脊髄神経に、一つ以上、散在性にできる。また、病巣が空間的に散在しているだけでなく、時間的にも症状が次々と出たり消失を呈する。多発性硬化症の病態には、免疫系が絡み、自己免疫疾患・炎症と捉えられている。また、脊髄神経が侵されることから、神経疾患のひとつとしても捉えられている。   Multiple sclerosis (MS) is an autoimmune disease of the human central nervous system that causes remission and relapse, and is a typical demyelinating disease in which only the myelin sheath of the central nervous system collapses due to inflammation. Are known. MS often develops from adolescence to the 40s, and includes symptoms such as staggering, blurred vision, double vision, difficulty in urinating, and pain and numbness when walking. Epilepsy may occur when children or young people develop. One or more lesions that cause symptoms can be scattered in the cerebrum or spinal nerve. In addition, the lesions are not only spatially scattered, but also symptoms appear and disappear one after another. The pathology of multiple sclerosis involves the immune system and is regarded as an autoimmune disease / inflammation. In addition, since the spinal nerve is affected, it is also regarded as one of the neurological diseases.

近年、MSの予防薬として、インターフェロンβ1bが使用され、Th1系細胞からTh2系細胞への免疫シフトにより再発予防に効果があるとされる(非特許文献1)。MSでは、脊髄にヒアルロン酸の蓄積がみられ、oligodendrocyteの前駆細胞の成熟が抑制されることが、報告されている(非特許文献2)。   In recent years, interferon β1b has been used as a prophylactic agent for MS and is said to be effective in preventing recurrence by immune shift from Th1 cells to Th2 cells (Non-patent Document 1). In MS, it has been reported that hyaluronic acid is accumulated in the spinal cord and maturation of precursor cells of oligodendrocytes is suppressed (Non-patent Document 2).

〔実施例1〕
本実施例では、多発性硬化症モデルである実験的自己免疫性脊髄炎(EAE)にPH-20(精巣ヒアルロニダーゼ)を投与し、その効果を検討した。
[Example 1]
In this example, PH-20 (testicular hyaluronidase) was administered to experimental autoimmune myelitis (EAE), which is a multiple sclerosis model, and the effect was examined.

多発性硬化症モデル動物
4週齢のLewisラットを購入し、5週齢になってから使用した。柴木らの方法(柴木謙次、野村恭一、大野良三、島津邦男:人参養栄湯による実験的自己免疫性脳脊髄炎の抑制.神経治療 19(2):159-166,2002)に準じて、ミエリン塩基性蛋白(myelin basic protein(MBP)Sigma社製)300μg/匹をPBS 100μlに溶解し、当量のフロインド完全アジュバンド(Freund Complete Adjuvant(FCA)、H37 Ra、Difco社製)および結核死菌(MT、H37 Ra、Difco社製)濃度を0.75mg/mlに調節混合し、動物の左右後肢足蹠に50μlずつ接種した。
本実施例では、接種直後の多発性硬化症モデル動物及び多発性硬化症発症時の多発性硬化症モデル動物(11匹)を用いた。
Multiple sclerosis model animals 4-week-old Lewis rats were purchased and used after 5 weeks of age. According to Shibaki et al.'S method (Kenji Shibaki, Junichi Nomura, Ryozo Ohno, Kunio Shimazu: Inhibition of experimental autoimmune encephalomyelitis by Ninjin Yoei-to. Neurotherapy 19 (2): 159-166,2002) , Myelin basic protein (myelin basic protein (MBP) manufactured by Sigma) 300 μg / mouse was dissolved in PBS 100 μl, and an equivalent amount of Freund Complete Adjuvant (FCA), H37 Ra, manufactured by Difco) and tuberculosis death The bacteria (MT, H37 Ra, Difco) concentration was adjusted to 0.75 mg / ml, and 50 μl each was inoculated into the left and right hind footpads of the animals.
In this example, a multiple sclerosis model animal immediately after inoculation and a multiple sclerosis model animal (11 animals) at the onset of multiple sclerosis were used.

EAE神経症候の評価
抗原接種後より毎日、2名の観察者により神経症状を5段階に分けて、観察した。EAE grade は、0:無症状、1:尾のtonusの低下、2:後肢不完全麻痺、3:時に尿便失禁を伴う後肢完全麻痺、4:四肢麻痺とした。
Evaluation of EAE neurological symptoms
Every day after the inoculation, neurological symptoms were divided into five stages and observed by two observers. EAE grade was defined as 0: asymptomatic, 1: decrease in tail tonus, 2: hindlimb incomplete paralysis, 3: hindlimb complete paralysis with urinary fecal incontinence, 4: limb paralysis.

投与方法及び群構成
ペントバルビタール麻酔下に、カテーテル(先端OD:0.245mm、MRE025、Braintree社製)を第6/7胸椎間から挿入し、留置後、マイクロシリンジ(25μl、伊藤製作所製)を用いて、試験物質6μL(10U/ml)を髄腔内投与(PH-20:0.06U/head)し、その後、1回/日、隔日に計6回投与した。なお、本実施例で使用したPH-20は、Hyaluronidase bovine testes, Type IV-S essentially salt-free, lyophilized powder(Sigma社製)である。
ヒアルロニダーゼ投与群(n=6)と、生理食塩水を投与したEAE対照群(n=5)の計2群でEAE神経症候を比較した。具体的には各群におけるEAE gradeを各個体について与えその平均値を算出し、臨床スコアー平均値とした。
Administration method and group composition Under pentobarbital anesthesia, a catheter (tip OD: 0.245mm, MRE025, manufactured by Braintree) was inserted from the 6/7 thoracic vertebra, and after placement, a microsyringe (25μl, manufactured by Ito Seisakusho) was used. Then, 6 μL (10 U / ml) of the test substance was administered intrathecally (PH-20: 0.06 U / head), and then administered once a day for a total of 6 times every other day. PH-20 used in this example is Hyaluronidase bovine testes, Type IV-S essentially salt-free, lyophilized powder (manufactured by Sigma).
The EAE neurological symptoms were compared between the hyaluronidase administration group (n = 6) and the EAE control group (n = 5) administered with saline. Specifically, EAE grade in each group was given to each individual, and the average value was calculated as the clinical score average value.

統計学的評価
神経スコアーはStudent’sのt-testを用いた。
Statistical evaluation Nerve score was Student's t-test.

結果
臨床スコアー平均値の経時的な変化を図1に示した。図1では、ヒアルロニダーゼ投与群のプロファイルを実線で示し、EAE対照群のプロファイルを破線で示した。図1から判るように、抗原接種後、ヒアルロニダーゼ投与群においては、EAE対照群と比較して、神経兆候の軽症化が認められた。EAE極期の神経兆候の比較では、抗原接種後16日目のEAE対照群の臨床スコアー平均値2.0±0.89に対し、ヒアルロニダーゼ投与群では16日目に1.2±0.48と有意な低値(P<0.05)を示した。以上の結果から、ヒアルロニダーゼの髄腔内隔日6回投与によって、EAEに対して神経学的にEAEの予防効果を有すると結論付けられた。従って、ヒアルロニダーゼは、多発性硬化症や急性散在性脳脊髄炎等の自己免疫疾患、炎症及び神経疾患の予防及び治療に有効と考えられる。
Results The changes over time in the mean clinical score are shown in FIG. In FIG. 1, the profile of the hyaluronidase administration group is indicated by a solid line, and the profile of the EAE control group is indicated by a broken line. As can be seen from FIG. 1, after the antigen inoculation, the hyaluronidase administration group showed milder neurological signs compared to the EAE control group. In the comparison of neurological signs at the extreme EAE stage, the mean clinical score of the EAE control group on the 16th day after the inoculation was 2.0 ± 0.89, whereas the hyaluronidase administration group was 1.2 ± 0.48 on the 16th day. And a significantly low value (P <0.05). From the above results, it was concluded that administration of hyaluronidase 6 times a day in the intrathecal space has EAE preventive effect on EAE neurologically. Therefore, hyaluronidase is considered effective for the prevention and treatment of autoimmune diseases such as multiple sclerosis and acute disseminated encephalomyelitis, inflammation and neurological diseases.

ヒアルロニダーゼ投与群及びEAE対照群における、臨床スコアー平均値の経時的な変化を示す特性図である。It is a characteristic view which shows a time-dependent change of the clinical score average value in a hyaluronidase administration group and an EAE control group.
