Thymocytes from preleukemic AKR mice aged 5-6 mo have an altered pattern of cell surface antigens. The expression of four MuLV-related antigens on the cell surface (GIX, GCSA, gp70, p30) is markedly increased in comparison to 2-mo-old AKR mice and approximates the heightened levels of these antigens found on thymic leukemia cells. H-2 and Thy-1 alloantigens also show characteristic modifications in relation to age and leukemia development. In contrast to the high Thy-1/low H-2 levels on 2-mo-old AKR thymocytes, thymocytes from 6-mo-old mice and thymic leukemia cells frequently show a low Thy-1/high H-2 surface phenotype. As thymocytes from mouse strains with a low incidence of leukemia do not show these changes, they appear to represent a stage in the conversion of normal cells to leukemia cells.
5至6月龄的白血病前期AKR小鼠的胸腺细胞具有改变的细胞表面抗原模式。与2月龄的AKR小鼠相比,细胞表面四种与小鼠白血病病毒(MuLV)相关的抗原(GIX、GCSA、gp70、p30)的表达显著增加,接近在胸腺白血病细胞上发现的这些抗原的升高水平。H-2和Thy-1同种异体抗原也显示出与年龄和白血病发展相关的特征性改变。与2月龄AKR胸腺细胞上高Thy-1/低H-2水平相反,6月龄小鼠的胸腺细胞和胸腺白血病细胞经常显示出低Thy-1/高H-2表面表型。由于白血病发病率低的小鼠品系的胸腺细胞没有显示出这些变化,它们似乎代表了正常细胞向白血病细胞转化的一个阶段。
