Description

A composition for immune regulation or enhancement comprising Dendropanax morbifera Lev. extract or an active ingredient isolated therefrom}

The present invention relates to a composition for immunomodulation or immune enhancement comprising a hwangchil tree extract. In addition, the present invention relates to a composition for immunomodulation or immuno-enhancement comprising the active ingredient DMW-2 or salts thereof separated from hwangchil tree leaf extract as an active ingredient.

In general, the human body protects the body and maintains homeostasis through an immune function to identify and remove when an invasion of an external pathogen occurs. Immune response is a series of reactions caused by activated immune cells against antigens, and the immune system is responsible for removing pathogens through infection, cognitive and humoral, and cellular responses to infection. In addition to the disease, it leads to various diseases.

Immunity refers to self-defense by removing the antigen by defending the host against the antigen, and is largely divided into innate immunity and acquired immunity. Innate immunity is a non-specific response to an antigen, which causes macrophage, natural killer cells (NK cells), and complements to cause an immune response. Acquired immunity remembers the first invading antigen, and when the antigen invades again, it specifically triggers an immune response to remove the antigen. Acquired immunity is divided into humoral immunity and cellular immunity, and humoral immunity involves B lymphocytes to recognize antigens, and then secrete antibodies to cause an immune response. In cellular immunity, T lymphocytes derived from the thymus recognize antigens and secrete cytokines or activate macrophages to induce an immune response.

In particular, in the immune response by T cells, an initial signal is transmitted into the cell from the TCR complex of the T cell that recognizes the antigen and another signal. This signal transduction process is shown by the action of PKC activator and ionophore, thereby increasing Ca ⁺⁺ ion in the cytoplasm of T cell. In addition, after phosphorylation of various proteins, the signal is finally transmitted to the nucleus. The initial signal transmitted from the cell membrane to the nucleus is expressed by the expression of various genes necessary for the proliferation and differentiation of T cells in the nucleus. This process is called transcriptional activation, and transcription of NF-AT, NF-kB and AP-1, which plays the largest role in T cell proliferation, occurs. In addition, transcription of IL-2 cytokines and IL-2 receptor genes appears. Through this, new cytokines are secreted to proliferate and differentiate T cells. T cell activity is linked to the synthesis of IL-2, and secreted IL-2 induces T cell proliferation. IL-2 is a T cell growth factor and activates immune cells such as T cells, B cells, and natural killer cells to display an immune response. IL-2 binds to IL-2R present on the surface of T cells and induces various intracellular responses. When IL-2 binds to IL-2R of T cells, T cell differentiation occurs and cytokines such as IFN-r (interferon-gamma) and TNF (tumor necrosis factor) are liberated, affecting the immune response. It also increases IL-1, IL-6, and TNF secretion in monocytes.

However, if the immune function is lowered, disorders in immune regulation occur due to causes of imbalance of cytokines in the body and proliferation imbalance of T / B cells. Accordingly, various immune diseases such as asthma, rhinitis, allergic rhinitis, atopic dermatitis, irritable dermatitis, cold, and chronic fatigue may occur. Therefore, the immune response of the human body must be balanced and regulated normally to maintain health, so prevention of immune regulation is more important than treatment. However, since the currently available therapeutic agents are immunopotentiators that have the potential for side effects to be taken for prevention, a substance capable of preventing and treating immune dysfunction is required.

To this end, research is being actively conducted to find a component capable of modulating immune activity from natural products with few side effects and to develop a formulation capable of modulating immune activity using the same. Korean Patent Publication No. 10-2015-0051174 discloses a composition for enhancing immunity comprising an alcohol extract of elm bark as an active ingredient, and Korean Patent Registration No. 10-1536652 contains a composition for boosting immunity including turmeric extract This is disclosed.

Since ancient times, the hwangchil tree ( Dendropanax morbifera Lev. ) Is a genus of the elmaceae ( oralaceae ). As a Korean native species, it is an evergreen large tree growing in the shady and humid broad-leaved forests of Jeollanam-do and Jeju islands and the hillsides of the island. The leaves are hairless, smooth, and misaligned on the surface, and the oval or elliptical leaves do not crack at all, or they may split deeply like a finger with 3-5 branches. If you look at the distribution of Hwangchil trees in Korea, it grows a lot in the beaches such as Jeju Island, Wando, Jeonnam, Daeheksando, and Geomundo. Dendropanax , the generic name for Hwangchil, is a compound word of the Greek word dendro (tree) and panax (all-powerful medicine). Hwangchil tree's scientific name, dendropanax mobifer, has the meaning of a panacea and is also called tree ginseng. Also, the name Hwangchil is a name given that yellow liquid appears as lacquer of lacquer when it is cut on the bark of Hwangchil. Hwangchil is used to process or color the surface in the process of making crafts. It has been used in various ways, such as lacquerware, Goryeo Buddha, and various other furniture and metals. According to the Korean native book, the roots and stems of Hwangchil tree have a sweet taste, warm properties, and are effective in Geopung-pung and Hwanghyeol-maek.

In addition, according to a recent study, a single component of Hwangchil and Hwangchil is used as a material with more interest as pharmacological effects such as antibacterial, anticancer, hyperlipidemia, antithrombotic anti-inflammatory and antioxidant effects are revealed. In relation to the immune enhancing effect of hwangchil, Korean Patent Publication No. 10-2015-0144061 discloses a composition for immunomodulation or immunopotentiation containing hwangchil tree stem extract as an active ingredient. However, there has been no exact report on the immunomodulatory effect of single components in hwangchil tree.

As a result, the present inventors have developed a composition for immunomodulation or immuno-enhancement comprising DMW-2, an active substance isolated from Hwangchil tree leaf extract or Hwangchil tree leaf extract.

The present inventors have shown that the ethylacetate fraction isolated from the extract of hwangchil tree leaf extract increases the activation of T cells, increases the transcription factors NF-AT, AP-1, NF-kB, and increases IL-2 cytokine production. As an effect, it was found that it is very effective for immunomodulation or immune enhancement.

Meanwhile, DMW-2 ((10E)-(-)-10,17-octadecadiene-12,14-diyne-1,9,16-triol), a compound isolated from the ethyl acetate fraction, is T cell Although proliferation was not activated, IL-2 cytokine production was significantly increased. In addition, the effect of activating transcription factors IL-2, IL-4, NF-AT, AP-1, and NF-kB involved in T cell proliferation was excellent.
