基因不相容的胎儿移植物能逃脱母亲的免疫攻击而存活下来的机制,至今仍未完全明了。各家对T细胞、T细胞亚群及B细胞的报导是矛盾的,且均未检测T细胞亚群的功能。本文作者检测了人妊娠时单克隆抗体(McAb)确定的T细胞、具有辅助和抑制表型的T细胞、NK细胞、体内激活的T细胞 The mechanism by which genetically incompatible fetal grafts survived the mother’s immune attack survives is still not fully understood. Each reported conflicting T-cell, T-cell subsets and B cells, and none of the tested T cell subsets functioned. The authors examined monoclonal antibodies (McAb) -determined T cells in human pregnancy, T-helper and suppressor phenotype T cells, NK cells, in vivo activated T cells
