Description

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

The present invention relates to a composition for preventing or treating a Th2-mediated immune disease, comprising an enzyme-treated pepper extract as an active ingredient.

The immune balance regulated by cytokines produced by Th1 (type 1 helper T) and Th2 (type 2 helper T) cells is called the Th1 / Th2 balance. Th1 cells are important for the regulation of cellular immunity, It plays an important role in humoral regulation. 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.

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. About 20% to 25% of the world's population is exposed to allergic diseases, and the prevalence is on a steady 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.

The type I immediate-type hypersensitivity reaction is divided into two stages. In the first step, the Th1 cell reaction which produces IL-12 and IFN-γ which suppresses the secretion of IgE and IgG1 by the invasion of the allergen and increases the secretion of IgG2a And Th2 (type 2 helper T) cell responses that produce IL-4, IL-5 and IL-13 are tilted toward Th2 and IL-4 and IL-13 are secreted by excessive immune response of Th2. It is said that 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, pepper ( Piperis Nigri Fructus) is the fruit of evergreen plant of the dicotyledonous plant pepper tree pepper and is a natural product familiar with spice.

1-4. Using ELISA Splenocyte  Cytokine analysis of culture medium

In order to measure the amount of IL-4 cytokine from the mouse spleen cell culture recovered according to the method of Example 1-3, IL-4 BD OptEIATM MOUSE ELISA kit and 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 the mouse spleen cells recovered through the method of Example 1-3 were dispensed into the wells, followed by reaction 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 amount of IL-4 cytokine was measured from the culture medium of mouse splenocytes according to the methods of Examples 1-3 and 1-4 in order to evaluate the inhibitory activity of Th2 immune response by the pepper extract treated with? -glucosidase Respectively.

Comparing the inhibitory activity of IL-4 production by each extract, the IC 50 (half maximal inhibitory concentration) inhibiting the production of IL-4 was about 25 ㎍ / ㎖ for the 70% ethanolic pepper extract without enzyme treatment Respectively. On the other hand, the 70% ethanolic pepper extract treated with β-glucosidase showed an IC 50 value of less than 6.25 ㎍ / ㎖. In conclusion, it was confirmed that the inhibition of IL-4 by pepper extract was significantly enhanced by about 4-fold by β-glucosidase treatment.

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.
