Abstract

Spleen cells from chickens inoculated 7 to 8 days previously with Marek's disease virus were cytotoxic for 51Cr-labeled cells of a Marek's disease lymphoblastoid cell line (MSB-1 line) in a 4-h in vitro cytotoxic assay. The cytotoxic activity of spleen cells was inhibited by pretreatment with antithymocyte serum and complement, but not with complement alone or in combination with anti-bursa cell serum or normal preimmune serum. The conclusion was that the effector cell in the above cytotoxic assay was a thymus-derived lymphocyte. Also, pretreatment of target cells with Vibrio cholerae neuraminidase enhanced in vitro cytotoxic activity of effector cells. Similar enzymatic treatment of effector cells had a negligible effect on cytotoxicity.

摘要

在一项4小时的体外细胞毒性试验中,7至8天前接种马立克氏病病毒的鸡的脾细胞对马立克氏病淋巴母细胞样细胞系(MSB-1系)的51Cr标记细胞具有细胞毒性。脾细胞的细胞毒性活性可通过抗胸腺细胞血清和补体预处理来抑制,但单独使用补体或与抗法氏囊细胞血清或正常免疫前血清联合使用则不能抑制。结论是上述细胞毒性试验中的效应细胞是胸腺来源的淋巴细胞。此外,用霍乱弧菌神经氨酸酶预处理靶细胞可增强效应细胞的体外细胞毒性活性。对效应细胞进行类似的酶处理对细胞毒性的影响可忽略不计。
