TECHNICAL FIELD

The present specification describes a composition for enhancing immunity, comprising a ginseng berry polysaccharide.

BACKGROUND ART

It is likely to become vulnerable to various infections or diseases when the body's immune function deteriorates. Macrophage is a cell which regulates the immune phenomenon by secreting various cytokines in the course of phagocytosis and elimination of bacteria or foreign substances and plays a pivotal role in the immune response to the antigen. Macrophages are involved in antigen presentation and nonspecific immune responses of lymphocytes and exhibit direct tumor cell-damaging activity. In addition, TLR (tool like receptor)-responding substances (LPS or natural products) are known to activate macrophages and produce cytokines such as IL-1, IL-6, IL-10, IL-12, and TNF-α, which can regulate proliferation of T cells and B cells, phagocytosis, and secondary immune responses such as protection against microbial infection.

IL-1, IL-6, and TNF-α are representative cytokines induced by macrophages and are known to play a pivotal role in the inflammatory response as a result of bacterial infection and be increased in inflammatory lesions. It has been reported that IL-6 cooperatively acts with IL-1 to be involved in the differentiation of T cells and B cells. TNF-α is known to have an antiviral action and play an important role in various biological reactions. In addition, IL-12 is a cytokine which induces NK cell activation and Th1-type immune response and is known to enhance the responsiveness to cellular foreign substances.

There is a demand for ingredients which are derived from natural products and effective in such immunity enhancement.
