코디세핀이 마우스 복강 대식세포에서 전염증성 사이토카인의 생성에 미치는 영향

국문 초록 (Abstract)

본 연구는 동충하초(Cordyces militaris) 유래의 기능성 물질인 코디세핀의 면역활성을 검증하기 위하여 C57BL6 마우스 복강 대식세포를 이용하여 코디세핀이 대식세포의 활성화에 미치는 영향에 대하여 시험하였다. 그 결과 LPS에 의해 유도된 마우스 복강세포는 코디세핀의 작용에 의해 IL-1β, IL-12, TNF-α의 염증성 사이토카인의 생성이 증대되어 초기 염증매개 반응을 유도하여 선천면역반응의 활성화와 그리고 면역작용에 있어 후기 적응면역의 전환으로의 T 림프구의 활성화가 예상된다. 또한 IL-6의 생성증대로 활성화된 T 림프구에 의해 B 림프구의 항체생성반응을 매개하는 면역반응도 상승할 것으로 사료된다. 그리고 대식세포에 의한 염증반응에서 염증매개인자인 NO와 H₂O₂의 생성을 증대시킴에 따라 대식세포의 독성작용을 활성화시켜 염증반응을 효과적으로 유도할 것으로 보이며, 또한 H₂O₂의 후기 생성을 저해하였는데 이는 염증반응에 유도될 수 있는 세포의 손상으로부터 세포를 보호할 수 있을 것으로 사료된다. 따라서 코디세핀은 외부인자로부터 염증매개성 면역반응의 증강작용을 나타내는 것으로 사료된다.

The effect of cordycepin purified from Cordyceps militaris on macrophage activation was investigated in peritoneal macrophages isolated from C57BL6 mice. Lipopolysaccharide-induced mouse peritoneal cells showed that cordycepin treatment increased the expression of the inflammatory cytokines interleukin (IL)-1β, IL-12, and tumor necrosis factor-α (TNF-α), leading to early inflammation-mediated reactions, the activation of immunological responses, and T lymphocyte activation. T lymphocytes, activated by a greater production of IL-6, resulted in antibody-generating immune reactions, suggesting that cordycepin was effective at inducing immunological responses. Consistent with the increase in the inflammation-mediating factors including nitric oxide (NO) and hydrogen peroxide (H₂O₂), the toxic response of macrophages was activated and effectively induced inflammation. These findings demonstrate that cordycepin is involved in reducing cell injury provoked by inflammatory reactions. Therefore, these results suggest that cordycepin treatment of mouse peritoneal cells induces inflammation-mediated immunological responses and immunostimulation.
