黑色素瘤B16细胞热休克蛋白—抗原肽复合物的体内外抑？…

目的：黑色素瘤Ｂ１６细胞胞浆ＨＳＰ－抗原肽复合物（ＨＡＣ）的制备、免疫原性的诱导及其抑瘤作用的研究。方法：采用Ｔｒｉｓ－ＨＣＩ提取和Ｓｅｐｈａｃｒｙｌ　Ｓ－２００凝胶过滤制备Ｂ１６细胞ＨＡＣ，通过Ｃ５７ＢＬ／６Ｊ小鼠体内诱导特异性ＣＴＬ，再经体内、体外实验检测其抑癌作用。结果：凝胶过滤获得的含６０～９７ｋＤ蛋白的４１，４７和５３管的ＨＡＣ可以降低肿瘤发生率、延长肿瘤出现时间及降低小鼠死亡率。结论：Ｂ１６细胞胞浆中的６０～９７ｋＤ的ＨＡＣ具有免疫原性及抑瘤作用，为制备肿瘤疫苗提供了实验依据。

in vivo and in vitro Anti-Tumor Effeciency of B16 Melanoma HSP-Antigen Peptide Complex (HAC)

Objective: To investigate the anti-tumor efficiency of B16 melanoma HACs in vivo and in vitro.Methods: Tris-HCI extract and Sephacryl S-200 gel filtration were applied to prepare B16 HACs, and the cytolokicity of specific CTL induced by HACs was tested. Results: The 41, 47 and 53 tube HACs obtained by gel filtration could decrease the tumor incidences, delay the time of tumor development and decrease the mortalitites of mice.Conclusion:60 ~ 97 kD HACs from B16 melanoma cytosol have the activites of inhibiting tumor and could be used in effective anti-tumor therapy.
