Description

TECHNICAL FIELD The present invention relates to a composition for prevention or treatment of a Th2-mediated immune disease comprising an extract of Pepper fermentation as an active ingredient,

The present invention relates to a composition for preventing, ameliorating, or treating a Th2-mediated immune disease, which comprises a pepper fermented extract as an active ingredient.

Allergy is a disease caused by a malfunction of the immune system, which causes irritation such as urticaria, itching, runny nose, and cough in a specific person. It is caused by environmental pollution, westernization of diet and lifestyle, , ≪ / RTI > and various allergens. Twenty to 25 percent of the world's population is exposed to allergic diseases, and the prevalence of this disease continues to rise.

Allergic reactions are traditionally divided into four classes based on the time and type of expression: type I-type III is a humoral immune response (immediate type) involving antibodies, type IV is a cell-mediated immune response Delay type). Most allergic reactions are type I, and are typical diseases such as asthma, rhinitis, conjunctivitis, food and drug allergy, and atopic dermatitis. In severe cases, anaphylaxis may occur.

Type I immediate-type hypersensitivity is divided into two stages. The first stage is IL-12, which suppresses the secretion of IgE and IgG1 by the invasion of allergen, and Th1 (type 1 helper T) cell response and a Th2 (type 2 helper T) cell response that produces IL-4, IL-5 and IL-13 are tilted toward Th2, -13 are secreted, and IgE-specific antibodies produced by B cells are attached to the surface of mast cells or basophils, and allergens are sensitized to allergens.

The second stage of the allergic manifestation is divided into an initial reaction and a late reaction. The initial reaction re-enters the body to stimulate mast cells and triggers the degranulation reaction. At this time, the vasodilation by histamine, lipid metabolites, cytokines, And late response is activated by infiltration of neutrophils, eosinophils, macrophages, Th2 cells, basophils, and the like in the tissues, thereby causing inflammation and causing atopic dermatitis, rhinitis and asthma. Among these degranulation secretions, histamine is the most well-known factor and is also used as an important indicator of allergic symptoms in relation to immediate hypersensitivity reaction.

Allergy remedies have been the mainstream in the 21st century and have been actively researched. The global market of about 26 trillion won has been formed, and the health functional food market is expected to grow to about 10% by 6.5 trillion won. Approximately 50 million people in the US have diverse allergic diseases and about $ 5.2 billion in the drug market. In Korea, the market for anti-allergic drugs is steadily increasing to KRW440bn and the health functional food market to KRW145bn.

However, most of the drugs currently used for the treatment of allergy are focused on the suppression of the secretion of histamine secreted in the last stage of the allergy mechanism, or the treatment of the symptoms caused by allergy. The treatment of allergic diseases can be done for a long period of time. Most of the drugs with excellent therapeutic effect are widely used for atopic dermatitis, allergic rhinitis and asthma as long as they are steroid drugs. However, long term use can cause serious side effects. Antihistamines also cause symptoms to feel alleviated, but long-term use causes side effects such as depression, concentration difficulties, lethargy, drowsiness, and hepatic disorders, and the problem of recurrence of allergic diseases is discontinued. Furthermore, since allergic diseases, especially atopic dermatitis, are mostly in children and adolescents, it is very important to develop a safe therapeutic agent free from toxicity and side effects, and researches to overcome these limitations are actively conducted. However, It is not easy. Accordingly, there is a growing need for the development of safe functional foods which can reduce the dose of these drugs and replace them to some extent, and have no side effects for long-term treatment.

On the other hand, fermentation is a phenomenon in which microorganisms decompose or change organisms with their own enzymes and produce beneficial end products. They have been widely used as human food cooking methods, and one third of human food It is fermented food. Fermented food is considered to be the best health food with its natural taste and aroma. Yogurt, antioxidant and antioxidant wine, and miso and kimchi in Korea are representative. Furthermore, it is known that bacteria that are rich in fermented foods such as yogurt, cheese, miso, etc. prevent allergic diseases. As well as taste, the beneficial effects of fermentation are widely known, and studies have been actively conducted to improve or treat diseases using fermented foods as well as fermented foods.

Specifically, many research results have been reported to improve the original function or to obtain new effects by adding various nutritional ingredients in addition to the original ingredients by fermenting natural products (Korean Patent Laid-Open No. 2013-0125969). For example, the fermented soybean fermented soybean fermented soybeans was recognized as a stabilizing raw material in the phytosanitary hospital after the postprandial glucose control function was suppressed by suppressing the absorption of sugar, and the toxicity reduction and immunity enhancement effect of the fermented extract of lactobacillus of mistletoe were also reported have. In addition to the development of safe natural material itself, there is no side effect for allergic response, and further research is needed to improve the efficacy or obtain new effects by using fermentation.

However, there have been few studies to improve the efficacy by fermenting pepper. Therefore, the present inventors have studied the effect of enhancing the antiallergic activity by preparing pepper fermented extract fermented with pepper, and completed the present invention based on this research.

The inventors of the present invention conducted intensive studies to enhance the antiallergic activity of pepper, and found that the inhibitory activity of IL-4 production in OVA-immunized mouse spleen cells compared with the pepper extracts of the pepper fermented extract prepared through microbial fermentation The present invention has been completed.

After removing the supernatant, 1 ml of RBC (red blood cell) lysing buffer (SIGMA R7757) was added and incubated for 3 minutes on ice. 10 ml of basal medium was further added, ≪ / RTI > centrifugation twice.

On the other hand, pepper fermented extracts (0day, 8day, and 12day) prepared according to the method of Example 1-1 were treated with OVA as an antigen at a concentration of 100 μg / Or 50 / / ml, and the mouse spleen cells cultured by the above method were treated at 5 × 10 6 cells / well. After incubation in a CO 2 incubator at 37 ° C for 72 hours, the cell culture medium was recovered.

1-3. Using ELISA Splenocyte  Cytokine analysis of culture medium

In order to measure the amount of IL-4 cytokine from the culture medium of the mouse spleen cells recovered according to the method of Example 1-2, an IL-4 BD OptEIATM MOUSE ELISA kit and a TGF-β kit (R & D Systems).

Specifically, a capture antibody was added to a 96-well plate and reacted overnight at 4 ° C. The plate was coated with an antibody, washed with a washing buffer (phosphate buffered saline with Tween 20; PBST), and diluted with assay diluent (10% FBS in PBS) was added to each well and reacted at room temperature for 1 hour to perform a blocking process. Next, 100 μl of the standard solution and the culture solution of mouse spleen cells recovered through the method of Example 1-2 were dispensed into the wells, and reacted at room temperature for 2 hours. After the reaction, 100 쨉 l of the secondary antibody conjugated with the IL-4 specific primary antibody capable of detecting IL-4 and streptavidin-Horseradish peroxidase (HRP) was dispensed into each well The reaction was allowed to proceed at room temperature for 1 hour. Then, 100 μl of a substrate solution (0.01% TMB in phosphate-citrate buffer) was added and developed at room temperature for 30 minutes. Then, 50 μl of 2 M H 2 SO 4 was added to each well to stop the color reaction. The absorbance was measured with a microplate reader at.

Example  2. Th1 / Th2  Cytokine-modulating activity test

The immune balance regulated by cytokines produced by Th1 and Th2 cells is called Thl / Th2 balance. Thl cells are important for the regulation of cellular immunity, and Th2 cells play an important role in the regulation of humoral immune. Th1 / Th2 balance is maintained constantly by interfering with cytokine mainly on IFN-γ and cytokine mainly on IL-4, which are important for differentiation of Th2, If broken, various immune diseases can be induced. For example, in the case of deflecting Thl, cellular immunity is resurfaced to enhance infection resistance, and when deflected to Th2, infection resistance is reduced, and conversely, allergy is enhanced.

Therefore, the amount of IL-4 cytokine was measured from the culture medium of mouse spleen cells by the methods of Examples 1-2 and 1-3 in order to evaluate the inhibitory activity of Th2 immune response by the pepper fermented extract.

Comparing the inhibitory activity of IL-4 production by each extract, the inhibitory activity of IL-4 was shown at 50 ㎍ / ㎖ of non-fermented pepper extract (0 day), while the extract of fermented black pepper (8 days), the extracts (12 days) fermented for 12 days at the concentration of 25 ㎍ / ㎖ showed the same IL-4 inhibitory activity as the unfermented pepper extract at the concentration of 12.5 ㎍ / ㎖ Respectively. In other words, it was found that the activity of inhibiting IL-4 was enhanced about 4 times by the fermentation process of pepper.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. There will be. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
