    潍坊医学院000112摘 要:目的研究香菇多糖增强肿瘤浸润淋巴细胞(TIL)抗瘤作用机制。方法将从肺癌中分离的TIL分别置于含IL-2或IL-2加香菇多糖培养液中培养30d,观察TIL对TNF-α、IFN-γ的分泌及淋巴细胞表型的作用。结果用两种方法分别培养25d时,IL-2加香菇多糖培养的TIL对TNF-α、IFN-γ的分泌作用均明显高于IL-2培养的TIL(P<0.05)。CD8+的比例明显高于IL-2组。结论香菇多糖增强TIL抗瘤作用与促进TNF-α、IFN-γ的分泌及细胞表型变化有关。

    Abstract:Objective To study the mechanism of Lentinan on increasing antitumor activity of tumor infiltrating lymphocytes(TIL).Method TIL isolated from patients with lung cancer was cultured in IL-2 or IL-2 combined with Lentinan for 30 days,the production of TNF-α,IFN-γ and phenotypes of TIL were observed.Result At 25 days,the percentage of CD8+and production of TNF-α,IFN-γof TIL cultured in IL-2 combined with Lentinan were higher than that of TIL cultured in IL-2(P<0.05).Conclusion That Lentinan enhance the antitumor activity of TIL relates to the increase of TNF-α,IFN-γand change of phenotype.
