几个研究小组已经报道了感染马立克氏病(MD)病毒的鸡淋巴细胞对同种异体MD淋巴母细胞样细胞系的细胞介导的细胞毒性(CMC)。最近,我们建立了从高度近交系鸡中获得的MD肿瘤细胞系,并以其主要和次要组织相容性抗原为特征。利用感染非致癌性MD病毒5B‐1后6 ~ 8天的鸡细胞系和淋巴细胞,研究了同种异体和同基因CMC的差异。异体细胞毒性可以很容易地证明,而同基因细胞毒性是一个罕见的事件。然而,CMC测定时间从4小时增加到8小时,确实增强了同基因细胞毒性。冷抑制实验表明,同种异体细胞毒性直接作用于与靶细胞具有相同主要组织相容性抗原的脾脏淋巴细胞上的同种异体抗原。细胞毒性不受靶细胞或效应细胞性别的影响,也不受效应细胞病毒感染性水平的影响。
Cell‐mediated cytotoxicity (CMC) of lymphocytes obtained from chickens infected with Marek's disease (MD) virus against allogeneic MD lymphoblastoid cell lines has been reported by several research groups. Recently, we established a number of cell lines from MD tumors obtained from highly inbred chickens and characterized for major and minor histocompatibility antigens. Allogeneicversussyngeneic CMC was studied using those cell lines and lymphocytes obtained from chickens 6‐8 days post infection with 5B‐1, a non‐oncogenic MD virus. Allogeneic cytotoxicity could be easily demonstrated, while syngeneic cytotoxicity was a rare event. However, increase of the CMC assay period from 4 to 8 h did enhance syngeneic cytotoxicity. Cold inhibition assays demonstrated that the allogeneic cytotoxicity was directed against alloantigens present on spleen lymphocytes sharing the same major histocompatibility antigens as the target cells. Cytotoxicity was not influenced by the sex of either target or effector cells or by the level of virus infectivity of the effector cells.
