초록

은행잎 유래 플라보놀 성분이 갖는 항아토피 활성에 대해 입증된 바는 드물다. 이 논문에서는 MC/9 비만세포에서의 은행잎 플라보놀의 항아토피 효과를 조사하기 위하여 ELISA와 Real-time PCR, western blot으로 은행잎 플라보놀을 분석하였다. 분석 결과 IL-13, MIP-1a의 생성량은 농도 의존적으로 현저하게 감소되었으며 IL-4, IL-5, IL-13, TNF-a 유전자 발현량은 25, 50, $100{\mu}g/m{\ell}$의 농도에서 효과적으로 억제되었다. western blot 분석 결과 c-jun과 NFAT-1단백질 발현이 감소되었음을 확인하였다. 이러한 결과들은 은행잎 유래 플라보놀 성분이 NFAT-1, c-jun 전사인자의 전사를 억제함으로써 MC/9 비만세포에서의 Th2 싸이토카인의 생성을 감소시키는 효과를 갖는 것을 나타낸다. 따라서 은행잎 유래 플라보놀 성분이 아토피 피부염 치료제로서 활용가능성이 있음을 보고하고자 한다.

The effects of Flavonol contents from Ginkgo biloba leaf on anti-atopy activity have not rarely been verified. This study is to investigate the effects of flavonol on Th2 cytokine production in MC/9 mast cells. For this, flavonol was analyzed by ELISA and Real-time PCR. Analysis results showed that flavonol significantly suppressed production of Th2 cytokines(IL-13, MIP-1a) in a dose dependent manner. The mRNA expression of IL-4, IL-5, IL-13, TNF-a were effectively restrained by Flavonol at the concentration 25,50,$100{\mu}g/m{\ell}$. And decrease of expression of NFAT-1, c-jun protein was confirmed by western blot analysis. These results indicate that flavonol has effects of decreasing the Th2 cytokine production in the MC/9 mast cell causing inhibition of transcription factors such as NFAT-1, c-jun. Thus, we would like to brief that flavonol may have the applicability as therapeutic agent for atopic dermatitis.
