초록

마늘의 주요 성분인 allicin투여 후 유도되는 사람 말초혈액의 단핵구의 유전자 발현에 미치는allicin의 효과를 규명하였다. DNA microarray를 이용하여, allicin이 chemokines, cytokine, 면역관련 유전자 및 신호전달 관련 유전자의 발현을 유도하는 것을 확인하였다. 반대로 allicin은 Th1 type의 획득면역 관련 유전자의 발현을 억제하였다. 염증세포에 있어서 allicin은 억제효과 및 자극 효과를 동시에 보여주었다. 이는 allicin이 휴지기 세포에서 먼저 증가시킨 특정 유전자의 발현을 이후에 감소시키는 결과를 보여주는 것으로 positive와 negative 효과를 발휘하는 새로운 기전을 제시하는 것이다. Allicin에 대한 광범위하고 새로운 관심을 고려해 볼 때 본 연구에서 보여주는 많은 유전자의 발현 양상은 좀 더 특정적이고 효과적인 치료법을 고안하는 데 유용할 것이다.

The effect of allicin, the major component of garlic (Allium sativum), on the gene expression profiles of peripheral blood mononuclear cells from healthy donors was analyzed. DNA microarray which can detect expression signal of 862 genes revealed that allicin induced the expression of cytokine, chemokine, and immune-related genes in peripheral blood mononuclear cells. In contrast, allicin repressed the expression of adaptive immune-related genes, which are expressed in T helper 1 Iymphocytes. Simultaneous inhibitory and stimulatory effects of allicin were found on inflammatory cells. It is likely that allicin down-regulated the expression of specific genes that were previously up-regulated in resting cells, suggesting a new mechanism by which they exert positive and negative effect. Considering the broad and renewed interest in allicin, the profiles we describe here will be useful in designing more specific and efficient treatment strategies.
