Rat monoclonal antibodies with reactivity directed against mouse GMG cells have been produced. One of the antibodies (GMG-1) reacts with a surface antigen of GMG cells and cross-reacts with T lymphocytes. Another (GMG-2) reacts with an intracellular antigen in GMG cells and with asialo-GM1 positive cells in the spleen. Three antibodies (GMG-3, -4, -5) bind to intracellular antigens in GMG cells. The cross-reactivity of these antibodies is discussed with reference to the lineage relationship of GMG cells to NK cells and T cells and the recent suggestion that NK cells and T cells have a common progenitor cell. It is proposed that GMG cells share this common progenitor cell but are otherwise independent of the NK or T cell lineages.
已制备出对小鼠GMG细胞具有反应性的大鼠单克隆抗体。其中一种抗体(GMG-1)与GMG细胞的表面抗原发生反应,并与T淋巴细胞发生交叉反应。另一种抗体(GMG-2)与GMG细胞中的细胞内抗原以及脾脏中去唾液酸GM1阳性细胞发生反应。三种抗体(GMG-3、-4、-5)与GMG细胞中的细胞内抗原结合。参照GMG细胞与NK细胞和T细胞的谱系关系以及最近关于NK细胞和T细胞具有共同祖细胞的观点,讨论了这些抗体的交叉反应性。有人提出,GMG细胞共享这种共同祖细胞,但在其他方面独立于NK或T细胞谱系。
