Abstract

Cytostatic effector cells against M-locus (Mls) determinants were generated in mice by immunization with Mls incompatible lymphocytes. A post-labelling assay of 14C-labelled uridine uptake by macrophage targets was employed to meaure the inhibitory activity of the effector cells. Using lymphocytes from Mls pseudocongenic mice to immunize donors of effector cells, it was confirmed that the cytostatic effect was via the Mls determinants expressed on the macrophage targets. Cytotoxic effector cells against M-locus (Mls) determinants were not detected by the cell-mediated lympholysis assay (CML) in a five day mixed lymphocyte culture (MLC) between Mls incompatible lymphocytes. Specificity of cytotoxic cells generated by culturing in vivo preimmunized responder cells and Mls incompatible stimulator lymphocytes did not correlate with the Mls determinant of the stimulator lymphocytes.

摘要

通过用与M位点(Mls)不相容的淋巴细胞免疫,在小鼠体内产生了针对Mls决定簇的细胞生长抑制效应细胞。采用对巨噬细胞靶标摄取14C标记尿苷的标记后测定法来测量效应细胞的抑制活性。利用来自Mls假同基因小鼠的淋巴细胞免疫效应细胞供体,证实细胞生长抑制效应是通过巨噬细胞靶标上表达的Mls决定簇介导的。在Mls不相容淋巴细胞之间进行的为期五天的混合淋巴细胞培养(MLC)中,细胞介导的淋巴细胞溶解试验(CML)未检测到针对M位点(Mls)决定簇的细胞毒性效应细胞。体内预免疫应答细胞与Mls不相容刺激淋巴细胞培养产生的细胞毒性细胞的特异性与刺激淋巴细胞的Mls决定簇不相关。
