Abstract
Description
본 발명은 생물전환된 도라지발효물을 포함하는 아토피피부염 치료용 조성물에 관한 것이다.The present invention relates to a composition for the treatment of atopic dermatitis comprising a bioconverted bellflower ferment.
아토피피부염은 피부의 소양증, 건조증, 홍반성 습진을 특징으로 하는 난치성 면역질환으로 유전적 요인 및 환경적 영향이 주된 발병요인으로 증가추세에 있다. 2010년 질병관리본부의 조사에 따르면 우리나라 소아에서 지난 12개월간 가려운 발진이 있었던 아토피피부염 유병률은 초등학생이 20.6%, 중학생이 12.9%로 나타나 연령이 어릴수록 아토피피부염의 발병률이 높은 경향을 나타냈으며 2000년 조사 결과인 13.4%, 6.7%에 비해 질환 발병률이 크게 증가하는 추세로 나타났다. 1990년부터 2010년 사이 아프리카는 9.9%에서 20.9%, 유럽은 18.9%에서 19.6%로, 아시아권의 일본은 10.1%에서 13.6%로 증가하였다. 도시화로 인한 서구사회와 이주자 그룹에서 높은 유병률을 나타내고 동유럽에 비해 서유럽, 개도국에 비해 선진국에서 발생 빈도가 높다.Atopic dermatitis is an intractable immune disease characterized by pruritus, dryness, and eczema erythematosus. Genetic factors and environmental influences are on the rise as the main pathogenic factors. According to a 2010 survey by the Korea Centers for Disease Control and Prevention, the prevalence of atopic dermatitis, which had itchy rashes in Korean children for the past 12 months, was 20.6% for elementary school students and 12.9% for middle school students, indicating that the incidence of atopic dermatitis tends to be higher with younger age. Compared to the results of the survey, 13.4% and 6.7%, the incidence of disease was significantly increased. Between 1990 and 2010, Africa increased from 9.9% to 20.9%, Europe from 18.9% to 19.6%, and Asia in Japan from 10.1% to 13.6%. It has a high prevalence rate in Western societies and migrant groups due to urbanization, and it is more frequent in Western Europe than Eastern Europe and in developed countries than in developing countries.
스테로이드제, 면역억제제, 항히스타민제, 피부보습제, 피부연화제 등이 모두 아토피피부염 치료에 사용되고 있으나 약리적인 치료방법으로 사용되는 약 중 경증환자에 사용되는 대표적인 것은 국소 스테로이드제, 국소 칼시뉴린저해제 및 항히스타민제이며, 이 중 항히스타민제는 가려움증 완화에 사용되나 그 효능이 높지 않아 큰 도움이 되지 못하고 있는 실정이다. 이에 따라 아토피피부염의 치료에는 주로 스테로이드제나, 칼시뉴린저해제와 같은 T세포 억제 면역조절제가 사용된다. 현재 경증 환자에 사용되는 국소 스테로이드제 및 중등증 이상의 환자에 사용되고 있는 대부분의 약들이 심각한 부작용을 나타내기 때문에 약물치료와 광선요법을 병용하여 치료효과를 높이고 부작용을 줄이려 하고 있다.Steroids, immunosuppressants, antihistamines, skin moisturizers, skin emollients, etc. are all used to treat atopic dermatitis, but among the drugs used as pharmacological treatments, representative drugs used for mild patients are topical steroids, topical calcineurin inhibitors and antihistamines. Among them, antihistamines are used to relieve itching, but their efficacy is not so high that they are not very helpful. Accordingly, in the treatment of atopic dermatitis, T cell suppression immunomodulators such as steroids or calcineurin inhibitors are mainly used. Currently, topical steroids used in mild patients and most drugs used in patients with moderate symptoms have serious side effects, so the combination of drug therapy and phototherapy is trying to increase the therapeutic effect and reduce side effects.
상기와 같이, 아토피피부염의 치료에 있어서 부작용을 줄이기 위한 노력의 일환으로 천연물 유래의 원료 및 제품 개발의 필요성이 대두되고 있다. 아토피성 피부 개선에 효과가 있다고 알려져 있는 천연물 유래의 기능성소재의 경우 대부분 비만세포 탈과립 억제 효과에 의존한다. 항히스타민제와 같은 효과가 기대되는 비만세포에서의 탈과립 억제는 아토피피부염 증상의 완화에 일정부분 효과가 기대되기는 하나, 아토피피부염에서 항히스타민제는 기본적으로 가려움증의 완화를 위해서 사용될 뿐이며, 이 또한 효능이 높지 않아 큰 도움이 되지 못하고 있는 실정인 점을 감안하면 비만세포에서의 탈과립 억제에 의한 효과는 크지 않을 것으로 사료된다. As described above, as part of an effort to reduce side effects in the treatment of atopic dermatitis, the need to develop raw materials and products derived from natural products has emerged. Functional materials derived from natural products, which are known to be effective in improving atopic skin, mostly rely on mast cell degranulation inhibitory effects. Antigranulation inhibition in mast cells, which is expected to have the same effect as antihistamines, is expected to be partially effective in relieving symptoms of atopic dermatitis, but antihistamines are basically only used to relieve itching in atopic dermatitis, and this is also highly effective. Considering the fact that it is not very helpful, the effect of inhibiting degranulation in mast cells is not expected to be significant.
지금까지 천연물 추출물을 유효성분으로 하는 아토피피부염 치료용 약학 조성물(KR 2018-0138265 및 KR 1898262) 등의 기술이 개발되었으나, 미생물(담자균류 균사)로 발효하거나, 추가로 효소 처리를 통해 생물전환된 도라지발효물을 유효성분으로 하는 아토피피부염 치료제나 예방제에 대한 기술 개발은 미비한 실정이다.Until now, technologies such as pharmaceutical compositions for the treatment of atopic dermatitis using natural extracts as active ingredients (KR 2018-0138265 and KR 1898262) have been developed, but they are fermented with microorganisms (Basicillus mycelium) or bioconverted through additional enzyme treatment. Technology development for atopic dermatitis treatment or prevention agent using fermented bellflower as an active ingredient is insufficient.
따라서 본 발명은 담자균류 균사로 발효하거나, 추가로 효소 처리를 통해 생물전환된 도라지발효물을 포함하는 아토피피부염 치료용 조성물 및 이의 효과에 대한 것이다.Therefore, the present invention relates to a composition for the treatment of atopic dermatitis and its effect, including fermented with basidiomycete hyphae or fermented bellflower fermented by further enzyme treatment.
본 발명은 상기와 같은 종래의 기술상의 문제점을 해결하기 위해 안출된 것으로, 담자균류 균사로 발효하거나, 추가로 효소 처리를 통해 생물전환된 도라지발효물을 포함하는 아토피피부염 치료용 조성물 또는 식품 조성물에 관한 것이다. 그러나 본 발명이 이루고자 하는 기술적 과제는 이상에서 언급한 과제에 제한되지 않으며, 언급되지 않은 또 다른 과제들은 아래의 기재로부터 당 업계에서 통상의 지식을 가진 자에게 명확하게 이해될 수 있을 것이다.The present invention was conceived to solve the problems of the prior art as described above, in a composition or food composition for treating atopic dermatitis comprising fermented bellflower fermented by fermentation with basidiomycete hyphae or further enzymatic treatment About. However, the technical problem to be achieved by the present invention is not limited to the problems mentioned above, and other problems that are not mentioned may be clearly understood by those of ordinary skill in the art from the following description.
이하, 본원에 기재된 다양한 구현예가 도면을 참조로 기재된다. 하기 설명에서, 본 발명의 완전한 이해를 위해서, 다양한 특이적 상세사항, 예컨대, 특이적 형태, 조성물 및 공정 등이 기재되어 있다. 그러나, 특정의 구현예는 이들 특이적 상세 사항 중 하나 이상 없이, 또는 다른 공지된 방법 및 형태와 함께 실행될 수 있다. 다른 예에서, 공지된 공정 및 제조 기술은 본 발명을 불필요하게 모호하게 하지 않게 하기 위해서, 특정의 상세사항으로 기재되지 않는다.

In the following description, for a thorough understanding of the invention, various specific details, such as specific forms, compositions and processes, etc. are set forth. However, certain embodiments may be practiced without one or more of these specific details, or with other known methods and forms. In other instances, well-known processes and manufacturing techniques have not been described in specific details in order not to unnecessarily obscure the present invention. Reference throughout this specification to “one embodiment” or “embodiment” means that a particular feature, form, composition, or characteristic described in connection with the embodiment is included in one or more embodiments of the present invention. Thus, the context of “in one embodiment” or “embodiment” expressed in various places throughout this specification does not necessarily represent the same embodiment of the invention. Additionally, particular features, shapes, compositions, or properties may be combined in any suitable manner in one or more embodiments.
본 발명 내 특별한 정의가 없으면 본 명세서에 사용된 모든 과학적 및 기술적인 용어는 본 발명이 속하는 기술분야에서 당 업자에 의하여 통상적으로 이해되는 것과 동일한 의미를 가진다.Unless otherwise defined in the present invention, all scientific and technical terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present invention belongs.
본 발명에서 담자균류란, 진균류의 한 아문으로 유성생식 한 결과로 담자기라는 세포가 되어 홀씨를 만드는 균류이다. 스스로 양분을 만들지 못하여 다른 생물체에 붙어 기생하며, 버섯으로 알려진 것이 많은데 표고버섯, 상황버섯, 차가버섯, 잎새버섯, 목이버섯, 눈꽃송이버섯 및 치마버섯 따위가 대표적이다. 성숙한 버섯의 갓주름 면에는 담자기가 빽빽이 생긴다. 담자균류 버섯의 대부분은 고등식물의 유체에서 부생적으로 생활하며, 특히 셀룰로오스와 리그닌을 분해하여 물질의 생물학적 순환에 없어서는 안 될 중요한 역할을 하지만, 또 수목의 뿌리에 균근을 형성하여 공동생활을 하는 것도 많다. 그밖에 식용균으로 중요시되거나 독버섯으로 주의를 해야 할 종류도 있다.Basidiomycete in the present invention is a fungus that becomes a cell called basidiomycete as a result of sexual reproduction as a subfamily of fungi to create spores. It cannot make nutrients by itself, so it is attached to other organisms and is parasitic, and many are known as mushrooms. Shiitake mushrooms, Pseudomonas mushrooms, Chaga mushrooms, Maitake mushrooms, Wood ear mushrooms, Snowflake mushrooms and skirt mushrooms are representative. Basidis are densely formed on the wrinkled side of mature mushrooms. Most of basidiomycete mushrooms live by-products in the fluids of higher plants, and play an indispensable role in the biological circulation of substances by decomposing cellulose and lignin in particular, but they also form mycorrhizal roots at the roots of trees to live in common. There are also many. There are other types that are considered important as edible bacteria or that need attention as poisonous mushrooms.
본 발명에서 균사란, 사상균(곰팡이)의 영양세포이다. 영양적 기능이나 생리적 기능 같은 기능 분화도 볼 수 있다. 형태적으로는 격벽의 유무가 분류에 사용되고 있으며, 포자의 발아관에서 발육하여 선단생장에 의해서 신장한다. 분지한 균사의 집단을 균사체(mycelium)라고 한다. 생리적 기능에 따라 배지나 기주의 표면 또는 내부에 들어가면서 신장하는 기저균사와 공기 중에서 신장하는 기생균사로 구별된다. 기생균사는 영양을 기저균사로부터의 이송에 의존하고 있으며, 그 일부는 포자 형성기관 등으로 분화한다. 유기물이 있고 적당한 습도와 온도 등 환경조건이 양호하면 여러 가지 균사조직을 형성한다. 자낭균류의 균사의 격막은 단순하지만 담자균류에서는 꺾쇠연결을 형성하는 것을 많이 볼 수 있다. 곰팡이류에서는 여러 갈래로 분지하여 실처럼 엉겨 있고, 버섯류에서는 집합하여 자실체를 만든다. 엽록소가 없어 광합성을 하지 못하고 기주생물에 붙어서 영양분을 흡수한다. 버섯인 담자균류의 경우, 포자에서 발아한 균사는 핵을 1개 가지고, 이것이 다른 균사와 융합하면 1개의 세포에 핵을 2개 가지게 된다. 핵을 1개 가진 균사를 1차 균사, 핵을 2개 가진 균사를 2차 균사라고 한다. 본 명세서에 있어서 담자균류 균사는 구체적으로 약용 및 식용 가능한 담자균류인 표고버섯, 상황버섯, 차가버섯, 잎새버섯, 목이버섯, 눈꽃송이버섯, 치마버섯 등의 균사에서 어느 하나를 선택하여 사용할 수 있으며, 이들 담자균류 균사는 한국미생물보존센터(KCCM), 한국생명공학연구원 생명자원센터(KCTC), 한국세포주은행(KCLB), 한국농업미생물자원센터(KACC), 미국표준균주배양수록보존소(ATCC) 등의 기관에서 균주를 분양받아 사용할 수 있다.In the present invention, mycelium is a vegetative cell of a filamentous fungus (fungus). Functional differentiation, such as nutritional or physiological functions, can also be seen. Formally, the presence or absence of a partition wall is used for classification, and it develops in the germination tube of spores and elongates by apical growth. A group of branched hyphae is called mycelium. Depending on their physiological function, they are divided into basal hyphae that elongate as they enter the surface or inside of the medium or host and parasitic hyphae that elongate in the air. Parasitic hyphae depend on the transfer of nutrients from the basal hyphae, and some of them differentiate into spore-forming organs. If organic matter is present and environmental conditions such as suitable humidity and temperature are good, various mycelial structures are formed. The diaphragm of the mycelium of associa fungi is simple, but in basidiomyces, it can be seen that it forms a clamp connection. In fungi, it is branched into several branches and tangled like a thread. In mushrooms, it aggregates to form fruiting bodies. Because of the lack of chlorophyll, photosynthesis is not possible and it is attached to host organisms and absorbs nutrients. In the case of basidiomycete, which is a mushroom, a hyphae germinated from a spore has one nucleus, and when it fuses with another hyphae, one cell has two nuclei. A hypha with one nucleus is called a primary hyphae, and a hyphae with two nuclei is called a secondary hyphae. In the present specification, the basidiomycete hyphae can be specifically selected and used from hyphae such as medicinal and edible basidiomycete shiitake mushrooms, phylum mushrooms, chaga mushrooms, Maitake mushrooms, tree ear mushrooms, snowflake mushrooms, and skirt mushrooms, These basidiomycosis hyphae are the Korea Microbial Conservation Center (KCCM), the Korea Research Institute of Bioscience and Biotechnology Life Resource Center (KCTC), the Korea Cell Line Bank (KCLB), the Korea Agricultural Microbial Resource Center (KACC), and the American Standard Strain Culture Recorded Preservation Center (ATCC). The strain can be distributed and used by such institutions.
본 발명에서 도라지(Platycodon grandiflorum)란, 굵은 뿌리줄기를 가지고 있는 여러해살이풀이다. 줄기는 곧게 서고 40~80cm 정도의 높이로 자라며, 가지를 거의 치지 않는다. 잎은 마디마다 서로 어긋나게 자리하거나 2~3장의 잎이 한 자리에 나기도 한다. 잎은 길쭉한 계란 꼴 또는 타원 꼴로 생겼으며 잎자루라고 할 만한 것은 없다. 잎의 양끝이 뾰족하고 가장자리에는 날카로운 톱니를 가지고 있고, 잎 뒷면은 흰 가루를 쓰고 있는 것처럼 보인다. 줄기 끝에 종과 같이 생긴 여러 송이의 큰 꽃이 피는데, 꽃의 끝 부분이 다섯 갈래로 갈라져 있고 5개의 수술을 가지고 있다. 꽃의 지름은 4cm 안팎이고 빛깔은 짙은 하늘빛이나, 간혹 흰색으로 꽃이 피는 것도 있다. 뿌리줄기를 약재로 사용하는데, 뿌리줄기에 포함된 사포닌(Saponin)의 일종인 플라티코딘(Platycodin)과 플라티코디게닌(Platycodigenin) 등이 거담작용과 진해작용을 한다고 알려져 있다.In the present invention, bellflower (Platycodon grandiflorum) is a perennial plant having a thick rootstock. The stem stands upright, grows to a height of 40~80cm, and rarely prunes branches. The leaves are alternately placed on each node, or 2-3 leaves may appear in one place. The leaves are shaped like an elongated egg or oval, and there is no such thing as a petiole. Both ends of the leaf are sharp and have sharp teeth at the edge, and the back of the leaf looks like white powder. Several large bell-like flowers bloom at the end of the stem. The end of the flower is divided into five and has five stamens. The diameter of the flower is about 4cm and the color is dark azure, but some flowers bloom in white. Rhizome is used as a medicinal material, and it is known that Platycodin and Platycodigenin, a kind of saponin contained in the rhizome, have an expectorant and antitussive action.
본 명세서에 있어서 도라지 또는 도라지 분말은 도라지 전체 또는 일부로 구성된 것을 의미하며, 도라지 일부는 도라지 뿌리, 뿌리털, 줄기, 가지, 잎, 나무갓, 껍질로 이루어지는 군으로부터 선택된 하나 이상일 수 있으나, 이에 한정하는 것은 아니다.In the present specification, the bellflower or bellflower powder means composed of all or part of bellflower, and a part of bellflower may be one or more selected from the group consisting of bellflower root, root hair, stem, branch, leaf, bark, and bark, but limited to this no.
본 발명에서 생물전환이란, 생물학적 방법을 통해 첨가된 물질의 구조적 변화를 유도하여 화학적으로 변형된 형태로 전환시켜 새로운 성분의 생성을 유도하는 것을 말한다.In the present invention, biotransformation refers to inducing a structural change of a substance added through a biological method and converting it into a chemically modified form to induce the generation of new components.
본 발명에서 발효란, 미생물이 자신이 가지고 있는 효소를 이용해 유기물을 분해시키는 과정을 말한다. 발효라고 하는 것은 효소작용에 의해 유기물이 간단한 화합물로 변화해 자유에너지를 내놓는 현상이지만, 일반적으로는 미생물이 유기물의 분해과정을 통해 대사물을 축적하는 현상을 말한다. 즉, 효모가 당을 무산소적으로 분해해서 에틸알코올과 이산화탄소로 하는 알코올 발효, 락트산균이 당을 무산소적으로 분해해서 락트산으로 하는 락트산 발효 등이 전형적인 발효이지만, 현재는 아세트산균이 공기 중의 산소를 이용해서 알코올을 아세트산으로 산화시키는 현상, 곰팡이가 공기 중의 산소를 이용해서 글루코오스를 글루콘산으로 산화시키는 현상 등도 각각 아세트산 발효, 글루콘산 발효 등으로 부르고 있다. 또 이러한 것들을 혐기적 발효, 호기적 발효(산화 발효)로 나누어 논하기도 하고, 위에 언급한 것 외의 혐기적 발효로는 글리세롤 발효, 아세톤부탄올 발효, 2, 3-부틸렌글리콜 발효, 부티르산 발효, 프로피온산 발효, 메탄 발효 등이, 또 호기적 발효로는 시트르산 발효, 이타콘산 발효, 숙신산 발효, 2-케토글루타르산 발효, 옥살산 발효, 푸마르산 발효, 소르보오스 발효 등이 있다. 이외에 미생물에 의한 아미노산, 비타민, 항생물질의 생산도 예를 들면 글루탐산 발효, 리보플라빈 발효, 페니실린 발효 등으로 불리는데, 그다지 좋은 호칭은 아니다. 발효작용명은 생산물로 부르는 것이 원칙이나, 때로는 셀룰로오스 발효, 펙틴 발효 등으로 기질의 이름을 붙이기도 한다.In the present invention, fermentation refers to a process in which microorganisms decompose organic substances using their own enzymes. Fermentation is a phenomenon in which organic substances are converted into simple compounds by enzyme action to release free energy, but in general, it refers to a phenomenon in which microorganisms accumulate metabolites through the decomposition process of organic substances. In other words, alcohol fermentation in which yeast decomposes sugar anaerobicly into ethyl alcohol and carbon dioxide, and lactic acid fermentation in which lactic acid bacteria anaerobicly decompose sugar into lactic acid, etc. are typical fermentations, but at present, acetic acid bacteria absorb oxygen in the air. A phenomenon in which alcohol is oxidized to acetic acid by use, and a phenomenon in which molds oxidize glucose to gluconic acid using oxygen in the air are also called acetic acid fermentation, gluconic acid fermentation, and the like. In addition, these are divided into anaerobic fermentation and aerobic fermentation (oxidative fermentation), and other anaerobic fermentations other than those mentioned above include glycerol fermentation, acetone butanol fermentation, 2, 3-butylene glycol fermentation, butyric acid fermentation, and propionic acid. Fermentation, methane fermentation, and the like, and aerobic fermentation include citric acid fermentation, itaconic acid fermentation, succinic acid fermentation, 2-ketoglutaric acid fermentation, oxalic acid fermentation, fumaric acid fermentation, and sorbose fermentation. In addition, the production of amino acids, vitamins and antibiotics by microorganisms is also called glutamic acid fermentation, riboflavin fermentation, penicillin fermentation, etc., but it is not a very good name. In principle, the name of the fermentation action is called the product, but sometimes the name of the substrate is given by cellulose fermentation or pectin fermentation.
본 발명에서 아토피피부염(atopic dermatitis)은 소양증, 건조증, 홍반성 습진을 특징으로 하는 피부질환의 난치성 면역질환을 지칭한다. 아토피피부염은 유전적 요인, 환경적 요인 등이 복합적으로 작용하는 것으로 알려져 있으며 피부장벽 이상, 면역학적 이상 등이 주요 발병요인으로 증가 추세에 있다. '아토피'와 '알레르기'라는 용어는 20세기 초부터 사용되기 시작했으며 그리스어에서 파생된 단어이다. 'atopy (아토피)'는 장소를 뜻하는 그리스어 'topos'에 반대의 뜻으로 사용되는 'a'를 앞에 붙여 장소 밖(out of place)의 의미를 가진 용어이다. 'allergy (알레르기)'라는 단어는 그리스어로 '다르다'는 뜻의 단어 'allos'와 '작동한다'는 뜻의 단어 'ergon'의 합성어이다. 정상적으로 받아들여야 하는 것들에 대하여 우리 신체가 비정상적으로 반응하는 경우, 즉 '변형된 반응'을 일컫는 단어로서 과민반응 (hypersensitivity)을 의미한다. 현재 이 두 가지 단어는 혼용되어 쓰이고 있다.In the present invention, atopic dermatitis refers to a refractory immune disease of skin diseases characterized by pruritus, dryness, and erythema eczema. Atopic dermatitis is known to have a combination of genetic and environmental factors, and skin barrier abnormalities and immunological abnormalities are increasing as major pathogens. The terms'atopic' and'allergy' began to be used in the early 20th century and are derived from Greek. 'atopy' is a term meaning out of place by prefixing'a', which is used in the opposite sense to the Greek word'topos', which means place. The word'allergy' is a combination of the Greek word'allos' meaning'different' and the word'ergon' meaning'to work'. When our body reacts abnormally to things that must be taken normally, that is, a word for'modified reaction', it means hypersensitivity. Currently, these two words are used interchangeably.
우리 몸은 외부에서 이물질이 침입하면 이로부터 자신을 보호하기 위해서 이물질을 제거하고 신체를 보호하기 위한 반응을 보이는데 이것을 면역반응이라고 한다. 이와는 달리 과민반응은 우리 몸에 해롭지 않은 것에 대해서도 면역반응을 보임으로써 오히려 조직을 파괴하여 유해한 방향으로 작동한다. 과민반응은 1형 과민반응, 2형 과민반응, 3형 과민반응, 4형 과민반응 등 크게 4가지로 나눌 수 있으며, 이중에서 1형 과민반응을 통상적으로 알레르기라고 한다. 1형 과민반응에 서는 외부에서 들어오는 이물질(혹은 '알레르겐'이라고 한다)에 대하여 면역글로불린-E(IgE)가 생성되고, 이 IgE가 알레르겐과 결합함으로써 두드러기, 기침, 콧물, 재채기, 호흡곤란 등의 증상이 나타나게 된다. 1형 과민반응은 즉시형 또는 IgE 매개형 과민반응이라고도 하는데, 그 이유는 알레르겐에 노출된 후 IgE의 매개에 의해 과민반응이 나타나고, 또한 과민반응이 나타나기까지의 기간이 매우 짧기 때문이다. 반면, 4형 과민반응은 알레르겐에 노출된 후 증상이 즉시 나타나지 않고 서서히 나타나게 되며 IgE의 생성이 없기 때문에 지연형 또는 세포 매개형 과민반응이라고도 부른다. 최근 알레르기의 기본 병리가 염증에 의해 발생한다는 것이 밝혀지면서 IgE와 상관없이 나타나는 경우도 알레르기에 포함하게 되었다. 결국 알레르기는 IgE와 관련이 있던 없던 간에 표적기관에 염증을 형성하는 과민반응으로 정의할 수 있다. 즉, 알레르기에는 IgE 의존성 알레르기과 함께 IgE 비의존성 알레르기가 포함된다.When foreign substances invade from the outside, our body removes foreign substances in order to protect itself from it and exhibits a reaction to protect the body, which is called an immune response. On the contrary, hypersensitivity reactions work in a harmful direction by destroying tissues by showing an immune response even to things that are not harmful to our body. Hypersensitivity reactions can be divided into four categories:
본 발명에서 엄밀한 의미에서 '아토피'라는 용어는 외부로부터 신체 내로 들어오는 이물질에 대하여 비정상적으로 IgE를 생성하는 성향을 의미한다. 따라서 '아토피'라는 용어는 '알레르기'라는 용어와 의학적으로 동일하지는 않다. 그러나 실제적으로는 같은 의미로 혼용하고 있다. 즉 IgE 매개성 과민반응이 임상적으로 증상으로 발현되는 경우를 '아토피질환'이라 하며 혼용하여 '알레르기질환'으로 부르며, 전통적으로 아토피피부염, 천식, 알레르기비염, 알레르기결막염 등이 이러한 질환으로 분류되고 있다. 아토피질환은 IgE 의존성 (IgE 매개성) 알레르기질환에 해당하며, IgE 비의존성 알레르기질환은 아토피 질환에 해당하지 않는다. 또한 간혹 '아토피피부염'이라는 용어가 너무 길어서 짧게 '아토피'라는 말로 대신하는 경우가 있지만 상기한 바와 같이 '아토피피부염'과 '아토피'라는 용어의 정의는 의학적으로는 분명히 다르므로 정확한 용어를 사용하는 것이 필요하다.In the strict sense of the present invention, the term'atopic' refers to a tendency to abnormally generate IgE for foreign substances entering the body from the outside. Therefore, the term'atopic' is not medically identical to the term'allergy'. However, they are actually used interchangeably in the same meaning. In other words, when IgE-mediated hypersensitivity reaction is clinically expressed as a symptom, it is referred to as'atopic disease' and is called'allergic disease', and traditionally, atopic dermatitis, asthma, allergic rhinitis, and allergic conjunctivitis are classified as these diseases. have. Atopic diseases correspond to IgE-dependent (IgE mediated) allergic diseases, and IgE-independent allergic diseases do not correspond to atopic diseases. In addition, sometimes the term'atopic dermatitis' is too long to be replaced with the word'atopic' for short, but as mentioned above, the definitions of the terms'atopic dermatitis' and'atopy' are clearly different medically, so the exact term is used. I need it.
또한 아토피피부염 및 두드러기와 알레르기비염은 IgE 의존성 (IgE 매개성) 알레르기질환임에도 불구하고 같은 개별질환의 치료법에 있어서는 확연한 차이가 있다. In addition, although atopic dermatitis, urticaria and allergic rhinitis are IgE-dependent (IgE-mediated) allergic diseases, there are distinct differences in the treatment of the same individual diseases.
아토피피부염의 경우 2015년 발간된 “2015 한국 아토피피부염 치료가이드라인”에서 경증 아토피피부염에는 “항히스타민제, 국소 칼시뉴린억제제, 국소 스테로이드제”가 제시되어 있으며, 또한 중등증, 중증 아토피피부염의 경우 전신치료에 있어서 “사이클로스포린, 단기 전신스테로이드제, 기타 전신면역조절제(AZA, MMF, MTX, IFN-γ, Alitretinoin), 광선치료, 항원특이면역치료, 생물학적 제제”가 제시되어 있다. In the case of atopic dermatitis, “2015 Korea Atopic Dermatitis Treatment Guidelines” published in 2015 suggests “antihistamines, local calcineurin inhibitors, and local steroids” for mild atopic dermatitis. In addition, for moderate and severe atopic dermatitis, systemic In treatment, "cyclosporine, short-term systemic steroids, other systemic immune modulators (AZA, MMF, MTX, IFN-γ, Alitretinoin), phototherapy, antigen-specific immune therapy, and biological agents" are suggested.
알레르기비염의 경우 대한천식알레르기학회에서 2005년 11월에 발간한 “임상의를 위한 진료 가이드라인 알레르기비염”에 의하면 치료의 약물요법으로 “항히스타민제, 류코드리엔 수용체 길항제, 스테로이드제, 혈관 수축제”가 제시되어 있으며, 스테로이드제는 효과가 거의 모든 면역반응의 억제를 통해 나타나므로 면역억제제라고 받아들여지고 있다.In the case of allergic rhinitis, according to the “Clinical Treatment Guidelines for Allergic Rhinitis” published in November 2005 by the Korean Society for Asthma and Allergy, “antihistamines, leukotriene receptor antagonists, steroids, blood vessel counts” Festival” is suggested, and steroids are accepted as immunosuppressants because their effects appear through suppression of almost all immune responses.
보다 구체적으로 설명하면 알레르기비염의 치료에 있어서 1차적으로 항히스타민제를 사용한다. 경구 항히스타민제는 표적세포의 H1수용체 길항작용을 통해 콧물, 재채기, 코 가려움증, 눈 증상에 효과적이나, 코막힘 증상은 잘 조절되지 않아 코막힘 증상이 있을 때에는 보다 효과적인 비강 내 항히스타민제를 사용한다. 그러나 항히스타민제로 충분한 효과를 얻지 못한 환자에서는 비강 내 스테로이드제, 류코트리엔 수용체 길항제, 경구 혈관 수축제를 추가하는 것으로 조절한다. 코막힘의 치료에는 비강 내 스테로이드제가 가장 효과적이다. More specifically, antihistamines are used primarily in the treatment of allergic rhinitis. Oral antihistamines are effective for runny nose, sneezing, nasal itching, and eye symptoms through antagonism of the H1 receptor of target cells, but when there is a nasal congestion symptom, more effective nasal antihistamines are used. However, in patients who do not achieve sufficient effects with antihistamines, the administration of intranasal steroids, leukotriene receptor antagonists, and oral vasoconstrictors is controlled. Nasal steroids are the most effective treatment for nasal congestion.
류코트리엔 수용체 길항제는 알레르기비염의 중요한 염증매개체인 류코트리엔이 수용체에 결합하여 작용하는 것을 차단하여 알레르기비염 환자에서 코 증상과 눈 증상 개선에 도움이 되며, 비강 내 스테로이드제와 병용 투여 시 증상 개선에 더욱 효과적이다. 단독으로는 항히스타민제와 효과가 비슷하며, 비강 내 스테로이드제에 비해서는 효과가 낮다. 천식의 치료에도 류코트리엔 수용체 길항제가 사용되므로 천식이 동반된 알레르기비염 환자에 특히 유용하다.Leukotriene receptor antagonists block the binding of leukotriene, an important inflammatory mediator of allergic rhinitis, to the receptor, helping to improve nasal and ocular symptoms in patients with allergic rhinitis, and are more effective in improving symptoms when administered with intranasal steroids. to be. By itself, it is similar in effect to antihistamines, and is less effective than intranasal steroids. Leukotriene receptor antagonists are also used in the treatment of asthma, so they are particularly useful in allergic rhinitis patients with asthma.
아토피피부염 치료에 있어서 항히스타민제는 기본적으로 피부 가려움증 완화를 위해서 사용될 뿐이며, 이 또한 효능이 높지 않아 큰 도움이 되지 못하고 있는 실정이다. 이는 아토피피부염에 있어서 가려움증을 유발하는 매개체가 히스타민 이외에도 너무 다양하기 때문에 항히스타민제만으로는 가려움증 조차도 효과적으로 조절할 수 없다는 데 있다. 최근 가려움증을 야기하는 여러 매개체 중 IL-31이 가려움증과 밀접한 연관이 있는 주된 요인으로 보고됨에 따라 IL-31 Receptor A의 단일클론 항체가 의약품으로 개발되어 아토피피부염의 가려움증 치료에 사용되기 시작했다. In the treatment of atopic dermatitis, antihistamines are basically only used to relieve itching of the skin, and this is also not very helpful because the efficacy is not high. This is because in atopic dermatitis, there are too many mediators that cause itching in addition to histamine, so antihistamines alone cannot effectively control itching. As IL-31 was recently reported as the main factor closely related to itching among several mediators that cause itching, a monoclonal antibody of IL-31 Receptor A was developed as a medicine and started to be used for the treatment of itching in atopic dermatitis.
반면에, 같은 IgE 의존성 알레르기 질환인 두드러기의 치료에 있어서 가려움증을 비롯한 임상 증상은 비만세포에서 분비되는 히스타민이라는 매개체에 의해 발생하기 때문에 항히스타민제에 의해 가려움증을 비롯한 두드러기의 주요 증상이 효과적으로 억제된다. On the other hand, in the treatment of urticaria, which is the same IgE-dependent allergic disease, clinical symptoms including itching are caused by a medium called histamine secreted from mast cells, so that major symptoms of urticaria, including itching, are effectively suppressed by antihistamines.
아토피피부염 및 두드러기와 알레르기비염은 같은 IgE 의존성 알레르기질환임에도 불구하고 병변부위가 피부 및 호흡기로 서로 달라 사용되는 치료제가 서로 다르며, 같은 치료제의 경우에도 사용 목적 및 효과가 전혀 달라 각각의 질환에 적합한 치료제 및 치료방식이 채택되고 있다. Although atopic dermatitis, urticaria and allergic rhinitis are the same IgE-dependent allergic diseases, the lesions are different from each other to the skin and respiratory system, and the treatments used are different, and even the same treatments have different purposes and effects, which are suitable for each disease. And treatment methods are being adopted.
본 발명에서 아토피피부염은 주로 영유아기에 발병되는 대표적인 난치성 질환으로 알려져 있으며 일반적으로 가려움(pruritus), 피부 건조, 염증을 동반한 아토피성 습진(eczema)을 말한다. 아토피피부염의 면역학적 기전으로는 Th2 면역반응의 항진과 함께 Th세포 중 Th1 과 Th2 면역반응의 불균형, cytokine 체계 이상(dysfunction), 랑겔한스세포의 활성 증가 등이 있다. 최근에는 Nograles 등에 의해 Th17 면역반응도 아토피피부염에 악영향을 미치는 것으로 보고되었다.In the present invention, atopic dermatitis is known as a representative refractory disease that occurs mainly in infancy, and generally refers to atopic eczema accompanied by itching, dry skin, and inflammation. Immunological mechanisms of atopic dermatitis include the enhancement of the Th2 immune response, the imbalance of the Th1 and Th2 immune responses among Th cells, the cytokine dysfunction, and the increase in the activity of Langelhans cells. Recently, it was reported that Th17 immune response also adversely affects atopic dermatitis by Nograles et al.
IgE 의존성 알레르기반응의 공통적인 기전은 ①알레르기를 유발하는 알레르기항원(외부항원)이 우리 몸에 들어와 항원특이 Th2세포의 활성화가 이루어지고, ②활성화된 Th2세포가 분비하는 사이토카인에 의해 B세포가 IgE 항체 생성 B세포로 전환되어 IgE 항체 생성이 유도되어 분비되면, ③분비된 IgE 항체가 비만세포(mast cell)와 결합하여 비만세포의 감작이 유도되고, ④이때 재차 외부에서 들어온 알레르기항원이 비만세포 표면에 결합된 IgE와 결합하면서 비만세포가 활성화되어 히스타민과 같은 여러가지 화학적 알레르기 매개물질을 분비하면서 알레르기 증상이 나타나게 된다.The common mechanism of IgE-dependent allergic reaction is ① Allergens (external antigens) that cause allergies enter our body, and antigen-specific Th2 cells are activated, ② B cells are activated by cytokines secreted by activated Th2 cells. When IgE antibody-producing B cells are converted to IgE antibody production and secreted, ③ the secreted IgE antibody binds to mast cells and sensitization of mast cells is induced. ④ At this time, the allergen from the outside is obese. Mast cells are activated while binding to IgE bound to the cell surface, secreting various chemical allergy mediators such as histamine, leading to allergic symptoms.
이 중 아토피피부염에서 Th2 사이토카인이 분비되기까지의 과정을 더 자세히 설명하면 7단계로 나눌 수가 있다. 알러젠이나 바이러스 등에 의한 피부의 각질형성세포, 섬유아세포, 비만세포, 및 수지상세포에서 TSLP를 생성하고(1단계), TSLP는 미성숙 수지상세포를 활성화시키고(2단계), TSLP에 의해 활성화된 미성숙 수지상세포는 케모카인 IL-8과 에오탁신-2를 분비하고 이것이 호산구와 호중구를 끌어들일 뿐만 아니라, 또한 TARC(thymus and activation-regulated chemokine)와 MDC(macrophage-derived chemokine)를 분비하여 Th2세포들을 병변 부위로 끌어들인다(3단계). TSLP에 의해 활성화된 골수계수지상세포(mDC)는 성숙해지고 림프절로 이동하게 된다(4단계). TSLP에 의해 활성화된 성숙 수지상세포는 OX40L을 표면에 발현하고, 이것은 림프절에서 항원에 특이적인 naive CD4+ T세포가 염증성 Th2세포가 되도록 촉진시킨다. Th2세포들은 IL-4, IL-5, IL-13 과 TNF를 생산하지만 IL-10을 생산하지는 않는다(5단계). 병변의 염증부위에서는 TARC와 MDC가 생성되기 때문에 염증성 Th2세포는 다시 병변 부위인 염증이 일어나는 곳으로 이동하게 된다(6단계). 염증부위에서는 염증성 Th2세포에 의해서 Th2 사이토카인인 IL-4, IL-5, IL-13과 TNF가 생성되며, 이 사이토카인들은 IgE 생성과 호산구 증가와 점액물질의 생성을 촉진한다(7단계).Of these, if the process from atopic dermatitis to the secretion of Th2 cytokines is described in more detail, it can be divided into 7 steps. TSLP is produced from keratinocytes, fibroblasts, mast cells, and dendritic cells of the skin caused by allergens or viruses (step 1), and TSLP activates immature dendritic cells (step 2), and immature dendritic cells activated by TSLP Cells secrete the chemokines IL-8 and eotaxin-2, which not only attract eosinophils and neutrophils, but also secrete thymus and activation-regulated chemokine (TAC) and macrophage-derived chemokine (MDC) to transport Th2 cells to the lesion site. Draw in (step 3). Myeloid dysphagia cells (mDCs) activated by TSLP mature and migrate to the lymph nodes (step 4). Mature dendritic cells activated by TSLP express OX40L on the surface, which promotes antigen-specific naive CD4+ T cells to become inflammatory Th2 cells in lymph nodes. Th2 cells produce IL-4, IL-5, IL-13 and TNF, but not IL-10 (step 5). Since TARC and MDC are generated at the inflammatory site of the lesion, the inflammatory Th2 cells move back to the site of inflammation, which is the lesion site (step 6). In the inflammatory site, Th2 cytokines IL-4, IL-5, IL-13 and TNF are produced by inflammatory Th2 cells, and these cytokines promote IgE production, eosinophil increase and mucus production (step 7) .
아토피피부염 환자가 가려움증으로 인해 피부를 긁거나 혹은 알러젠에 노출되면 피부의 각질형성세포에서 TSLP가 분비되며 이렇게 분비된 TSLP는 랑게르한스세포에 영향을 주면서 결과적으로 활성화된 염증성 Th2 세포에서 Th2 사이토카인을 분비시키는 것으로 알려져 있다.When atopic dermatitis patient scratches the skin due to itching or is exposed to allergens, TSLP is secreted from the keratinocytes of the skin, and this secreted TSLP affects Langerhans cells and as a result secretes Th2 cytokines from activated inflammatory Th2 cells. It is known to make.
면역학적 관점에서 아토피피부염은 Th2 면역반응의 항진과 함께 Th1/Th2 라는 특정 면역반응의 균형이 깨지면서 발생하는 질환이다. 이때 중요한 역할을 하는 것이 TSLP(흉선기질림포포이에틴, Thymic stromal lymphopoietin)인데, 아토피피부염 발생단계에서 피부각질세포 등에서 TSLP가 분비되어 naive Th0세포를 Th2세포로 분화시킴으로써 Th2 면역반응을 일으키게 되는데, TSLP가 과도하게 분비되게 되면 이로 인해 Th2 면역반응의 항진과 함께 Th1/Th2 균형이 무너지면서 아토피피부염이 진행되거나 악화되는 것이다. 면역학적 관점에서 볼 때 아토피피부염의 치료는 TSLP의 생성을 억제하여 Th2 면역반응을 감소시켜 Th1/Th2 면역반응의 균형을 회복시킬 필요가 있다.From an immunological point of view, atopic dermatitis is a disease that occurs when the balance of specific immune responses called Th1/Th2 is broken along with the enhancement of the Th2 immune response. At this time, it is TSLP (Thymic stromal lymphopoietin) that plays an important role. TSLP is secreted from skin keratinocytes, etc. in the stage of atopic dermatitis development, causing Th2 immune response by differentiating naive Th0 cells into Th2 cells. When TSLP is secreted excessively, the Th2 immune response increases and the Th1/Th2 balance collapses, leading to atopic dermatitis progression or worsening. From an immunological point of view, treatment of atopic dermatitis needs to restore the balance of Th1/Th2 immune responses by suppressing the production of TSLP and reducing the Th2 immune response.
TSLP은 주로 피부의 각질형성세포와 기도 및 비점막의 상피세포에서 주로 만들어지며 미성숙 골수계수지상세포(mDC)를 자극하는데, 이는 상기의 미성숙 수지상세포가 성숙 수지상세포로 되기 위해 heterodimeric TSLP receptor(수용체)를 발현한다. TSLP-activated 수지상세포는 naive CD4+ T cells를 Th2 표현형으로 분화시키고, Th2 chemotactic cytokine인 TARC(CCL17) 및 MDC(CCL22)와 함께 costimulatory molecule인 OX40 ligand를 발현하여 Th2 기억세포의 증식을 촉진시킨다. 뿐만 아니라 TSLP는 수지상세포에 발현되는 IL-12 p40 수용체를 억제하고, Th1 면역반응을 억제하여 더욱 더 Th2 면역반응을 촉진한다. TSLP는 Th2 세포에서의 IL-4 유전자의 전사를 활성화시키고, 비만세포에서 IL-13의 생성을 촉진시키며, 호염구의 반응을 증대시켜 호산구를 침윤시킴으로써 알레르기 염증반응을 악화시킨다. 그러므로 TSLP는 아토피피부염 시작에 핵심적인 역할을 한다. TSLP는 아토피피부염 환자의 상피세포에서 발현된다. 또한, 마우스에서 피부 각질형성세포에서의 TSLP 과발현은 감작된 흡입항원에 대한 염증반응을 증폭시킨다.TSLP is mainly made from keratinocytes of the skin and epithelial cells of the airways and nasal mucosa, and stimulates immature myeloid dendritic cells (mDC), which is a heterodimeric TSLP receptor (receptor) in order for the immature dendritic cells to become mature dendritic cells. Express. TSLP-activated dendritic cells differentiate naive CD4+ T cells into Th2 phenotype, and promote the proliferation of Th2 memory cells by expressing costimulatory molecule OX40 ligand together with Th2 chemotactic cytokines TARC (CCL17) and MDC (CCL22). In addition, TSLP inhibits the IL-12 p40 receptor expressed in dendritic cells, suppresses the Th1 immune response, and further promotes the Th2 immune response. TSLP activates the transcription of the IL-4 gene in Th2 cells, promotes the production of IL-13 in mast cells, and increases the response of basophils to infiltrate eosinophils, thereby exacerbating the allergic inflammatory response. Therefore, TSLP plays a key role in the initiation of atopic dermatitis. TSLP is expressed in epithelial cells of atopic dermatitis patients. In addition, TSLP overexpression in skin keratinocytes in mice amplifies inflammatory responses to sensitized inhaled antigens.
아토피피부염은 심한 가려움증이 가장 특징적인 증상으로 이를 완화시켜 주는 것이 삶의 질 향상과 피부병변의 악화를 막을 수 있는 효과적인 방법이다. 아토피피부염의 가려움증이 증폭되는 기전을 간략히 정리하면, 외부자극이 손상된 피부장벽을 뚫고 피부에 도달하면, 알레르기 염증반응이 유발되고, 그 결과 발생한 가려움증이 '가려움증 → 긁기 → 염증 → (다시) → 가려움증 → 긁기 → 염증 → ……'의 악순환을 통해 걷잡을 수 없이 증폭되는 것이다. Atopic dermatitis is the most characteristic symptom of severe itching. Relieving it is an effective way to improve the quality of life and prevent the worsening of skin lesions. Briefly summarizing the mechanism by which the itching of atopic dermatitis is amplified, when external irritation penetrates the damaged skin barrier and reaches the skin, an allergic inflammatory reaction is triggered, and the resulting itching is'itching → scratching → inflammation → (again) → itching. → scratching → inflammation →… … It is amplified beyond control through the vicious cycle of'.
아토피피부염에서 피부염증으로부터 가려움증에 이르는 기전은 아직까지 완전히 밝혀지지 않았지만 염증반응에 의해 생성되어 가려움증을 야기하는 여러 매개체 중 Interleukin-31(IL-31)이 가려움증과 밀접한 연관이 있는 주된 요인으로 보고 있다. IL-31은 주로 Th2세포에 의해 생성되며, 감각 신경(Sensory nerve) 및 피부 각질형성세포 등에 발현되어 있는 IL-31 수용체와의 결합을 통해 신호를 보내게 되는데, 이때 IL-31은 Sensory nerve의 IL-31 수용체와 결합하여 가려움증을 유도하고, 또한 각질형성세포의 IL-31 수용체와 결합하여 TARC(CCL17), MDC(CCL22), S100A7, β-defensin2의 발현을 증가시키고, filaggrin, corneodesmosin의 발현을 억제함으로써 아토피피부염에서 나타나는 피부병변을 악화시키게 된다.The mechanism from skin inflammation to itching in atopic dermatitis has not yet been fully elucidated, but interleukin-31 (IL-31) is considered to be the main factor closely related to itching among several mediators that are produced by inflammatory reactions and cause itching. . IL-31 is mainly produced by Th2 cells, and sends a signal through binding to the IL-31 receptor expressed in the sensory nerve and skin keratinocytes. At this time, IL-31 is the sensory nerve. It binds to IL-31 receptor to induce itching, and increases expression of TARC(CCL17), MDC(CCL22), S100A7, β-defensin2 by binding to IL-31 receptor of keratinocytes, and expression of filaggrin, corneodesmosin By suppressing the skin lesions appearing in atopic dermatitis worsen.
중증의 아토피피부염 환자를 비롯하여 많은 아토피피부염 환자들(약 90%)의 피부에 S. aureus 균이 증식하고 있는 것으로 알려져 있다. 최근에는 Th2 사이토카인들이 S. aureus를 증식하기에 좋은 조건을 만든다고 알려져 있으며, 반대로 S. aureus는 Th2 사이토카인의 분비를 촉진시킨다고 알려져 있다.It is known that S. aureus bacteria are proliferating on the skin of many atopic dermatitis patients (about 90%) including severe atopic dermatitis patients. Recently, it is known that Th2 cytokines create favorable conditions for proliferation of S. aureus, whereas S. aureus is known to promote the secretion of Th2 cytokines.
Th2 사이토카인은 S. aureus 알파톡신에 의한 각질형성세포의 사멸을 촉진한다고 알려져 있으며, 델타톡신은 IgE의 생성을 촉진하고 Th2 사이토카인의 효과를 증가시킨다고 알려져 있다. 또한 Superantigen으로 알려진 Staphylococcal enterotoxin B는 비만세포에서의 탈과립 증가 및 IgE 항체의 분비를 촉진하고, Th2 사이토카인의 분비를 촉진시켜 병변을 악화시킨다고 알려져 있다. 뿐만 아니라 S. aureus의 Peptidoglycan는 마우스에서 Th2 면역반응을 유도할 수 있다고 알려져 있다. 이는 Peptidoglycan이 TLR2의 리간드라는 것과 관련되어 있는 것으로 알려져 있다. 또한 각질형성세포에서의 TSLP 생성이 S. aureus의 membrane과 diacylated lipopeptide에 의한 TLR2 및 TLR6의 pathway를 통해 유도된다는 것도 보고되어 있다.Th2 cytokine is known to promote the death of keratinocytes by S. aureus alphatoxin, and deltatoxin is known to promote IgE production and increase the effect of Th2 cytokine. In addition, Staphylococcal enterotoxin B, known as superantigen, is known to increase degranulation in mast cells and promote the secretion of IgE antibodies and aggravate lesions by promoting the secretion of Th2 cytokines. In addition, it is known that Peptidoglycan of S. aureus can induce Th2 immune response in mice. It is known that Peptidoglycan is a ligand of TLR2. It has also been reported that TSLP production in keratinocytes is induced through the pathways of TLR2 and TLR6 by the membrane of S. aureus and diacylated lipopeptide.
결론적으로 Th2 사이토카인은 S. aureus의 증식을 도와주고, 반면에 S. aureus는 TSLP 및 Th2 사이토카인을 유도할 수 있어, S. aureus가 아토피피부염을 악화시킬 수 있다는 점이다.In conclusion, Th2 cytokine helps the proliferation of S. aureus, whereas S. aureus can induce TSLP and Th2 cytokine, so S. aureus may exacerbate atopic dermatitis.
이를 극복하기 위해서 임상가이드라인에서는 2차 감염 치료에서 항생제 등의 사용을 권하고 있으며, 특히 본 특허에서 제시하는 소재가 TLR4 아고니스트(agonist), LPS 경쟁적 저해제(competitive inhibitor)의 Th1 어쥬번트(adjuvant)로서 Class II 항생제 어쥬번트로 사용될 수 있다는 점에서 아토피피부염에 추가적인 효과를 기대할 수 있을 것으로 판단된다.To overcome this, the clinical guidelines recommend the use of antibiotics in the treatment of secondary infections. In particular, the materials presented in this patent are TLR4 agonist, and Th1 adjuvant of LPS competitive inhibitor. As it can be used as a Class II antibiotic adjuvant, it is expected that additional effects on atopic dermatitis can be expected.
한국 아토피피부염 치료 가이드라인(2015)에 따른 치료의 가이드라인은 아래와 같다.The guidelines for treatment according to the Korean Atopic Dermatitis Treatment Guidelines (2015) are as follows.
아토피피부염은 경증 환자와 중등증/중증 환자의 치료방법이 구분되어 있다. 경증 환자의 경우는 증상이 악화되도 중등증 이상으로 진행되지 않지만, 중등증 환자는 악화되면 중증으로 진행되기 때문이다.Atopic dermatitis is treated with mild patients and moderate/severe patients. This is because in the case of mild patients, even if the symptoms worsen, it does not progress to more than moderate symptoms, but in the case of moderate patients, it progresses to severe.
아토피피부염 환자는 증상과 상관없이 기본치료로 보습제의 사용 및 악화인자의 회피, 환자교육을 받아야 한다. 경증 아토피피부염 환자의 피부 병변에는 국소 스테로이드제 및 국소 칼시뉴린억제제 등의 국소 항염치료가 병변을 소실시키기 위한 적극치료로 사용되며, 가려움증을 호소하는 경우 항히스타민제를 사용한다. 참고로 일반 염증과는 달리 일반 비스테로이드성 소염제는 기본 치료로 사용되지 않는다.Regardless of symptoms, atopic dermatitis patients should use moisturizers as basic treatment, avoid exacerbation factors, and receive patient education. For skin lesions of patients with mild atopic dermatitis, topical anti-inflammatory treatments such as topical steroids and local calcineurin inhibitors are used as active treatments to eliminate the lesion, and antihistamines are used when itching is complained of. For reference, unlike general inflammation, general nonsteroidal anti-inflammatory drugs are not used as a basic treatment.
중등증 이상의 환자는 경증 환자의 치료제를 포함하여, 적극치료로 전신치료제가 반드시 사용되어야 한다. 또한, 중등증, 중증 아토피피부염의 경우 전신치료에 있어서 "사이클로스포린, 단기 전신스테로이드제, 기타 전신면역조절제(AXA, MMF, MTX, IFN-γ, Alitretinoin), 광선치료, 항원특이면역치료, 생물학적 제제"를 사용한다. 또한 중등증 이상 피부염이 악화될 때는 습포치료와 항생제를 사용할 수도 있다.For patients with moderate or higher severity, systemic treatments must be used as active treatment, including treatments for mild patients. In addition, in the case of moderate to severe atopic dermatitis, in systemic treatment, "cyclosporine, short-term systemic steroids, other systemic immunomodulators (AXA, MMF, MTX, IFN-γ, Alitretinoin), phototherapy, antigen-specific immune therapy, biological agents Use ". In addition, when moderate or severe dermatitis worsens, poultice therapy and antibiotics may be used.
증상이 사라진 이후에는 유지를 위해서 주 2~3회 국소 칼시뉴린억제제 또는 국소 스테로이드제를 도포하고, 재발을 방지하기 위하여 유지(proactive)치료를 권장한다. 그 이외에 아직 효과가 뚜렷하게 증명되지는 않았지만 보조치료로 달맞이꽃종자유, 프로바이오틱스 및 프리바이오틱스, 비타민 D를 사용할 수 있다.After symptoms disappear, topical calcineurin inhibitors or topical steroids are applied 2-3 times a week for maintenance, and proactive treatment is recommended to prevent recurrence. Other than that, although the effect has not yet been clearly demonstrated, evening primrose oil, probiotics and prebiotics, and vitamin D can be used as an adjunct treatment.
아토피피부염 대부분의 증상이 피부에 나타나기 때문에 단순 피부질환으로 오해할 수 있지만, 아토피피부염은 피부장벽 이상뿐 아니라 과도하게 활성화된 면역계 기능 이상으로 기저 염증이 지속적으로 재발하는 게 원인으로 아토피피부염은 염증으로 분류될 수는 있지만, 일반적인 염증과는 다르기 때문에 염증질병에서 흔히 사용하는 비스테로이드성 소염제는 거의 치료제로 사용되지 않는다.Most of the symptoms of atopic dermatitis appear on the skin, so it can be misunderstood as a simple skin disease.However, atopic dermatitis is caused by a continuous recurrence of underlying inflammation due to not only abnormal skin barrier but also abnormally activated immune system function. Although they can be classified, since they are different from general inflammation, nonsteroidal anti-inflammatory drugs commonly used in inflammatory diseases are rarely used as therapeutic agents.
따라서, 아토피피부염 질환 치료에 있어서 무엇보다 염증이 아닌 Th2 면역과민반응을 치료하는 것이 장기적으로 우수한 효과를 보인다. 그러므로 아토피피부염을 치료하기 위한 방법은 엄밀히 말하면 염증 억제가 아닌 Th2 면역과민반응 억제 등 면역반응의 방향을 바꾸는 것이라 할 수 있다.Therefore, in the treatment of atopic dermatitis disease, treatment of Th2 immune hypersensitivity rather than inflammation shows superior long-term effects. Therefore, the method for treating atopic dermatitis, strictly speaking, can be said to change the direction of the immune response such as suppressing the Th2 immune hypersensitivity reaction rather than suppressing inflammation.
본 발명에서 아토피피부염(atopic dermatitis)은 가려움증을 주된 증상을 갖는 피부질환 중 하나로, 주로 유아기 또는 소아기에 시작되어 가려움, 피부건조증, 피부 병변, 태선화, 아토피성 습진, 홍반 및 Th2 면역과민반응성 염증 등을 동반한다. 아토피피부염에서 파생되는 증상들은 만성 재발성으로 경과되는 특징이 있어 환자에게 지속적인 정신적, 신체적 고통을 수반한다. 아토피피부염의 치료제로는 현재 스테로이드제, 칼시뉴린억제제, 항히스타민제, 면역조절제, 인터페론-감마 등이 사용되고 있으며, 이중 상기 스테로이드제는 빠른 호전을 보이는 장점으로 인해 아토피피부염의 치료제로 가장 널리 사용되고 있으나 사용을 줄이거나 끊게 되면 증상이 급격히 악화되고, 또한 쿠싱증후군 등을 포함한 각종 심각한 부작용의 위험이 있는 단점이 있다. 이와 같은 스테로이드제의 단점으로 인해 스테로이드제를 대체하여 칼시뉴린억제제, 면역조절제, 인터페론-감마 등이 사용되는 추세이나, 상기 면역조절제는 피부가 화끈거리거나 고혈압, 신기능 장애 등의 부작용의 위험이 있으며, 또한 상기 항히스타민제는 졸음 및 입이 마르는 등의 증상을 동반하며, 상기 인터페론-감마를 주사하는 경우에는 그 치료효과가 수주일 후에 나타나 즉각적인 증상완화 효과를 기대할 수 없는 단점이 있다. 이러한 종래의 화학조성물에 의한 아토피피부염 증상 완화제의 단점을 보완하여 장기적으로 사용하더라도 부작용이 없고, 효과적으로 아토피피부염 증상을 예방, 완화 또는 치료할 수 있는 것으로 자연(특히, 식물)에서 추출한 천연물질을 이용한 아토피성 피부질환 치료제가 각광을 받고 있다.In the present invention, atopic dermatitis is one of the skin diseases having the main symptom of itching, and itching, skin dryness, skin lesions, lichenification, atopic eczema, erythema and Th2 immune hypersensitivity inflammation, etc. are mainly initiated in infancy or childhood. Accompany. Symptoms derived from atopic dermatitis are characterized by chronic recurrence and are accompanied by persistent mental and physical pain to the patient. As treatments for atopic dermatitis, steroids, calcineurin inhibitors, antihistamines, immunomodulators, interferon-gamma, and the like are currently being used. Of these, the steroids are most widely used as treatments for atopic dermatitis due to their rapid improvement. If you reduce or quit, the symptoms rapidly worsen, and there is a disadvantage in that there is a risk of various serious side effects including Cushing's syndrome. Due to the shortcomings of such steroids, calcineurin inhibitors, immunomodulators, interferon-gamma, etc. are used in place of steroids, but the immunomodulators are at risk of side effects such as burning skin, high blood pressure, and renal dysfunction. In addition, the antihistamine is accompanied by symptoms such as drowsiness and dry mouth, and when the interferon-gamma is injected, the therapeutic effect appears several weeks later, and an immediate symptom relief effect cannot be expected. Atopic dermatitis symptom relief using natural substances extracted from nature (especially plants) is capable of effectively preventing, alleviating or treating atopic dermatitis symptoms without side effects even if used for a long period of time by supplementing the shortcomings of these conventional chemical compositions. Sexual skin disease treatments are in the spotlight.
또한 아토피피부염의 경우 치료에 스테로이드성 소염제, 면역억제제, 항히스타민제 외에 필요시 이차감염치료제 등이 사용되고 있으나, 면역 과민성 자체는 개선시키지 못하고 부작용이 심각하여, 장기간의 반복적인 사용에 어려움이 있다. 따라서 피부외용제가 주로 사용되는 경증 치료 및 유지치료에 있어서 몸 안에서 발생한 Th2 면역과민반응을 억제할 수 있는 적당한 경구용 전신치료제가 없는 현실에서, 약물치료와 광선요법을 병행하여 치료효과를 높이고 부작용을 줄이려 노력하고 있으며 또한 아토피피부염의 개선에 도움이 될 수 있다고 알려진 프로바이오틱스(유산균) 등의 건강기능식품 섭취도 이루어지고 있다.In addition, in the case of atopic dermatitis, in addition to steroidal anti-inflammatory drugs, immunosuppressants, and antihistamines, secondary infection treatments are used as needed, but immune hypersensitivity itself is not improved and side effects are serious, making it difficult to use repeatedly for a long time. Therefore, in the reality that there is no suitable oral systemic treatment that can suppress the immune hypersensitivity reaction to Th2 that occurs in the body in mild treatment and maintenance treatment, which are mainly used for external skin, the treatment effect is increased and side effects are reduced by combining drug treatment and phototherapy. It is trying to reduce it, and also eating health functional foods such as probiotics (lactic acid bacteria), which are known to be helpful in improving atopic dermatitis, are being made.
이를 종합하면 현재까지는 면역반응을 억제하는 기전을 가지고 있는 거의 모든 제품의 차이점은 스테로이드제가 가장 광범위하게 면역을 억제하고, 반면에 최근의 제품들은 좁은 범위의 면역만 억제하는 것이 특징이다. 하지만 질병의 진행을 변화시킬 정도의 항진된 Th2 면역반응과 함께 Th1/Th2 불균형을 해결하는 제품은 아직까지 없다고 할 수 있다.Taken together, the difference between almost all products that have a mechanism to suppress the immune response up to now is that steroids suppress immunity most widely, whereas recent products are characterized by suppressing only a narrow range of immunity. However, it can be said that there is no product that solves the Th1/Th2 imbalance along with the enhanced Th2 immune response enough to change the disease progression.
본 발명은 이러한 항진된 Th2 면역반응과 함께 Th1/Th2 불균형을 해결할 수 있는 Th1 어쥬번트를 함유한 것으로써, 담자균류 균사로 발효하거나, 추가로 효소 처리를 통해 생물전환된 도라지발효물을 포함하는 아토피피부염 치료용 조성물 및 이의 효과에 대한 것이다.The present invention contains a Th1 adjuvant capable of resolving the Th1/Th2 imbalance along with such an enhanced Th2 immune response, and fermented with basidiomycete hyphae or further comprising fermented bellflower bioconverted through enzymatic treatment. It relates to a composition for the treatment of atopic dermatitis and its effect.
본 발명에서 IgE란, 면역글로불린 E라고도 불리는 항체 단백질이다. 알레르기반응에서 중요한 역할을 하므로 종종 "알레르기 항체"라고도 한다. 특정물질(알레르겐)에 알레르기반응을 보이는 경우, 면역체계가 일반적으로 무해한 물질을 몸에 유해하다고 잘못 판단하는데, 이런 특정한 물질에 노출되면 면역체계는 우리 몸을 보호하기 위해 IgE를 생산하기 시작한다. IgE 항체는 몸 안에 남아있다가 다음에 알레르겐 물질과 다시 접촉하면 알레르기반응을 일으킨다. 결과적으로 알레르기가 있는 사람은 혈중 IgE 농도가 증가하며, IgE는 각 알레르겐에 특이도를 나타낸다.In the present invention, IgE is an antibody protein also called immunoglobulin E. It is often referred to as "allergic antibodies" because it plays an important role in allergic reactions. When you are allergic to a specific substance (allergen), the immune system erroneously judges that generally harmless substances are harmful to the body. When exposed to these specific substances, the immune system begins to produce IgE to protect our body. The IgE antibody remains in the body and causes an allergic reaction the next time it comes into contact with the allergen. As a result, in people with allergies, blood IgE levels increase, and IgE exhibits specificity for each allergen.

결과. 생물전환된 도라지발효물 내의 유효성분 입증result. Proof of active ingredient in bioconverted bellflower fermentation
도라지발효분말의 선천성 면역활성 효능을 확인하기 위하여 대식세포주인 RAW264.7 세포에서의 사이토카인 분비능 및 분비패턴을 조사하였으며, 분비패턴을 통해 작용부위(특이수용체, specific receptor)를 유추하고, 이를 확인하기 위하여 유추된 특이수용체에 대한 억제제를 처리하여 신호전달이 차단되는지를 확인함으로써 작용부위를 확인하였다.In order to confirm the innate immune activity efficacy of fermented bellflower powder, the ability to secrete cytokines and secretion patterns in RAW264.7 cells, a macrophage cell line, were investigated, and the site of action (specific receptor) was inferred and confirmed through the secretion pattern. In order to do so, the site of action was confirmed by treating an inhibitor for the inferred specific receptor to check whether signal transduction was blocked.
사이토카인 분비패턴을 조사한 결과, LPS와 동일하게 TNF-α, IL-6, IL-10 및 IFN-β가 분비되고, IL-1β, IL-4, IL-5, IL-12p70 및 IFN-α는 분비되지 않음을 확인할 수 있었다. LPS는 TLR4에 의해 인식되는 대표적인 리간드로 잘 알려져 있는 바, 이를 통해 도라지발효분말은 TLR4에 인식되어 신호를 매개할 것이라 유추할 수 있었다.As a result of examining the cytokine secretion pattern, TNF-α, IL-6, IL-10 and IFN-β were secreted in the same manner as LPS, and IL-1β, IL-4, IL-5, IL-12p70 and IFN-α Was not secreted. Since LPS is well known as a representative ligand recognized by TLR4, it could be inferred that fermented bellflower powder would be recognized by TLR4 and mediate signals.
도라지발효분말의 처리가 대식세포주에서 4가지 사이토카인의 생산을 효과적으로 유도함에 따라, 도라지발효분말 내 유효성분을 확인하고자 하였다(도 2 참조). 도라지발효분말 내 다당체분획물을 분리·정제하고 대식세포주에 처리하여 4가지 사이토카인의 발현량을 측정하였으며, 다당체분획물의 회수율을 고려하여 도라지발효분말의 1/20 농도로 처리하였다. 그 결과, 다당체분획물만 처리하였을 경우에도 도라지발효분말을 처리한 것과 유사한 수준의 사이토카인이 생성되어 도라지발효분말의 유효성분은 다당체인 것으로 확인되었다.As the treatment of fermented bellflower powder effectively induces the production of four cytokines in macrophage cell lines, it was attempted to confirm the active ingredient in fermented bellflower powder (see FIG. 2). The polysaccharide fraction in the fermented bellflower powder was isolated and purified and treated on a macrophage cell line to measure the expression levels of four cytokines, and treated at a concentration of 1/20 of the fermented bellflower powder in consideration of the recovery rate of the polysaccharide fraction. As a result, even when only the polysaccharide fraction was treated, cytokines similar to those treated with the bellflower fermented powder were produced, and the active ingredient of the bellflower fermented powder was confirmed to be a polysaccharide.
또한, TLR4의 특이성 억제제인 TAK242를 함께 처리하여 사이토카인의 양을 측정한 결과, TAK242 처리 시 도라지발효분말 및 다당체분획물의 처리에 의해 유도된 4가지 사이토카인 모두 생성이 완벽히 억제되는 것을 확인하였다. 따라서, 도라지발효분말 및 도라지발효분말의 다당체분획물은 TLR4에 결합하여 대식세포의 활성화를 유도하는 TLR4 작용제(agonist)을 확인하였다.In addition, as a result of measuring the amount of cytokines by treatment with TAK242, a specific inhibitor of TLR4, it was confirmed that the production of all four cytokines induced by treatment of fermented bellflower powder and polysaccharide fraction during TAK242 treatment was completely inhibited. Therefore, the fermented bellflower powder and the polysaccharide fraction of the fermented bellflower powder were identified as TLR4 agonists that induce activation of macrophages by binding to TLR4.
도라지발효분말의 대식세포에서의 면역활성 관련 사이토카인 분비패턴을 조사한 결과, TNF-α, IL-6 및 IFN-β의 발현을 매우 높게 유도하는 것을 확인할 수 있었으며, 이 중 IFN-β는 I형 인터페론으로 항균, 항바이러스 효과가 있으며 Th1 세포의 분화에 기여하여 Th1 면역반응을 유도하는 대표적인 사이토카인으로 Th1 면역반응을 유도하는 반면, Th2 및 Th17 면역반응을 억제하는 면역조절 기능이 있는 사이토카인이다.As a result of investigating the cytokine secretion pattern related to immune activity in macrophages of fermented bellflower powder, it was confirmed that it induces very high expression of TNF-α, IL-6 and IFN-β, of which IFN-β is type I. Interferon has antibacterial and antiviral effects, and is a representative cytokine that induces Th1 immune response by contributing to the differentiation of Th1 cells. It is a cytokine with immunomodulatory function that suppresses Th2 and Th17 immune responses while inducing Th1 immune responses. .
따라서 도라지발효분말은 Th1 면역반응을 특이적으로 활성화시킬 수 있는 TLR4 작용제의 Th1 어주번트(adjuvant)이며, 대식세포에서 PGE2 및 NO 생성 등을 억제하는 일반적인 염증억제제와는 다른 기전을 갖는 물질인 것으로 평가할 수 있었다.Therefore, fermented bellflower powder is a Th1 adjuvant of TLR4 agonist that can specifically activate Th1 immune response, and it is a substance that has a mechanism different from general anti-inflammatory drugs that inhibit PGE 2 and NO production in macrophages. Could be evaluated.

결과 1. 생물전환된 도라지발효물의 LPS 경쟁적 억제제 입증
LPS 복강투여에 따른 복강 내 호중구 침윤 유도 효과를 확인한 결과, 200ng의 LPS를 주사했을 경우, 호중구의 침윤이 최대로 일어나고 이후 일정하게 유지되는 것을 확인하였다. 하지만, 생물전환된 도라지발효물 다당체분획은 동일량을 주사했을 경우 LPS와 달리 복강 내 호중구 침윤을 거의 유도하지 않았으며, LPS와 동시 처리 시 LPS에 의한 호중구 침윤을 억제하는 것을 확인하였다(도 3 참조). 생물전환된 도라지발효물 다당체 분획물은 LPS와 달리 복강 내 호중구 침윤을 유도하지 않으며, 오히려 LPS에 의해 유도된 복강 내 호중구 침윤이 생물전환된 도라지발효물 다당체 분획물에 의해 억제되어 LPS에 대한 경쟁적 억제제임을 입증하였다. 따라서, 생물전환된 도라지발효물은 체내에서 염증반응을 유도하지 않는 안전한 물질이며, 오히려 LPS와 경쟁적으로 작용할 수 있는 물질인 것으로 평가할 수 있었다. As a result of confirming the effect of intraperitoneal administration of LPS inducing neutrophil infiltration, it was confirmed that when 200ng of LPS was injected, neutrophil invasion occurred to the maximum and remained constant thereafter. However, when the same amount of the bioconverted bellflower fermented polysaccharide fraction was injected, unlike LPS, it was confirmed that intraperitoneal neutrophil infiltration was hardly induced, and neutrophil infiltration by LPS was inhibited when simultaneously treated with LPS (Fig. 3). Reference). Unlike LPS, the bioconverted bellflower fermentation polysaccharide fraction does not induce intraperitoneal neutrophil infiltration, and rather, LPS-induced intraperitoneal neutrophil infiltration is inhibited by the bioconverted bellflower fermentation polysaccharide fraction, which is a competitive inhibitor for LPS. Proved. Therefore, the bioconverted bellflower fermentation product could be evaluated as a safe material that does not induce an inflammatory reaction in the body, but rather a material that can act competitively with LPS.

Therefore, it could be determined that the material was converted to a material having superior efficacy than the original product by the bioconversion process (see FIG. 6). In addition, it was confirmed that the administration of the bioconverted bellflower fermentation according to the present invention can control the chronic inflammatory reaction by inhibiting the production of TSLP, and can effectively alleviate the itching caused by atopic dermatitis to alleviate atopic dermatitis. I did.
결과 4. 아토피피부염이 유발된 마우스의 혈청 내 갈렉틴-9(galectin-9)의 발현 수준의 증가 확인
아토피피부염이 유발된 마우스의 혈청 내 갈렉틴-9의 양을 측정하여 생물전환된 도라지발효물의 갈렉틴-9 발현 조절 효과를 확인하였다. 마우스 희생 후 혈청 내 존재하는 갈렉틴-9의 양을 ELISA 방법으로 측정한 결과, 아토피피부염의 유발로 갈렉틴-9의 발현이 정상마우스 대비 3.3배 증가하며, 또한 도라지 원물을 투여한 마우스에서는 갈렉틴-9의 발현이 추가로 거의 증가되지 않는 것을 확인하였다. 반면에, 생물전환된 도라지발효물을 투여한 마우스에서는 갈렉틴-9의 발현이 정상마우스 대비 약 5배 정도, 양성 대조군 대비 약 2배 정도 대폭 증가되는 것을 확인하였다(도 7 참조). 갈렉틴-9은 TGF-β1의 발현을 증가시킴으로써 Treg 세포의 활성화를 유도할 수 있으며, Treg 세포를 통한 염증반응 억제에 중요한 역할을 하는 단백질로 알려져 있어, 갈렉틴-9은 생물전환된 도라지발효물을 투여하는 경우에 Treg 세포의 활성화를 통해 아토피피부염을 효과적으로 억제할 수 있는 것을 확인하였다.By measuring the amount of galectin-9 in the serum of atopic dermatitis-induced mice, the effect of controlling the expression of galectin-9 of the bioconverted bellflower fermentation was confirmed. As a result of measuring the amount of galectin-9 in the serum after mouse sacrifice by ELISA, the expression of galectin-9 increased 3.3 times compared to normal mice due to the induction of atopic dermatitis. It was confirmed that the expression of lectin-9 was hardly increased further. On the other hand, it was confirmed that the expression of galectin-9 was significantly increased in the mice to which the bioconverted bellflower fermentation was administered, about 5 times compared to the normal mice and about 2 times compared to the positive control group (see FIG. 7). Galectin-9 can induce activation of Treg cells by increasing the expression of TGF-β1, and it is known as a protein that plays an important role in inhibiting inflammatory responses through Treg cells, so galectin-9 is a biotransformed bellflower fermentation. When water is administered, it has been confirmed that atopic dermatitis can be effectively suppressed through activation of Treg cells.
