Abstract

The in-vitro immunomodulatory function of the activity of murine natural-killer (NK) cells induced by redginseng acidic polysaccharide (RGAP) was examined. RGAP induced the significant enhancement of NK cell activity against the Yac-1 tumor cells. The treatment of splenocytes cultured with RGAP for 16 h resulted in a significant increase in NK activity at the E:T ratio of 100:1, and in a 239 and 250% increase at 10 and $100{\mu}g$/ml, respectively. We also demonstrate that RGAP treatment increased the production of interferon (IFN)-$\gamma$ (17-125%) and tumor necrosis factor (TNF)-${\alpha}$ (15-100%), suggesting that the increase in NK cell cytotoxicity could be due to the enhancement of the NK cell production of both cytokines. In addition, RGAP had a stimulating effect on lymphocyte proliferation in the presence of mitogens. Overall, these results suggest that RGAP has an immunopotentiating effect on NK cells, which can support the development of clinical studies on RGAP.

본 논문은 홍삼 산성 다당류 (RGAP)의 생체외 쥣과 NK 세포 활성 향상에 대한 내용으로 주요 내용은 다음과 같다. RGAP는 Yac-1 종양 세포에서 NK 세포 활성을 향상시켰다. 비장 세포에 16시간 동안 RGAP 10 및 $100{\mu}g$/ml을 처리한 결과, NK 활성이 239와 250% 증가 하였다. 인터페론 (IFN)-$\gamma$ 생성은 17-125% 증가하였고, 종양 괴사 인자 (TNF)-${\alpha}$ 생성도 15-100% 증가 하였다. NK 세포의 세포 독성 증가는 NK 세포가 생성하는 이 두 시토카인 증가가 원인이다. 따라서 RGAP는 NK 세포에 미치는 면역증진 효과가 있다는 내용이다.
