Abstract: The present invention relates to an influenza virus surface protein-derived recombinant hemagglutinin (HA) protein forming a trimer and use thereof, and more specifically to a recombinant vector for producing an influenza virus surface protein-derived HA protein forming a trimer, a transformant transformed by the recombinant vector, a method for producing an influenza virus surface protein-derived HA protein forming a trimer using the recombinant vector, an influenza virus surface protein-derived HA protein produced by the method, and the use thereof in preventing, ameliorating or treating influenza virus-infected disease.

Abstract: There is provided a composition including a veratric acid for preventing or treating inflammatory diseases. The veratric acid of the present invention has an excellent effect of inhibiting production of nitric oxide, an excellent activity of inhibiting production of IL-1? as a pro-inflammatory cytokine, and an excellent effect of inhibiting phosphorylation of MAPK, NF-?B, GSK-3?, and c-Raf in a macrophage cell stimulated by a stimulation factor that causes an inflammatory reaction. Thus, it can be used for development of medicines for treating inflammatory diseases which can be caused by excessive inflammatory reactions. Further, the veratric acid of the present invention does not induce toxicity to cells and is stable in the body. Thus, it can be used as a material of a health functional food capable of preventing or improving inflammatory diseases.
