Mta is a maternally transmitted cell surface antigen found in most mouse strains. It serves as a target for unrestricted T killer cells. All 49 embryos transferred between positive and negative mothers, even as early as 10-15 hr after fertilization, developed into mice with the Mta type of their original mothers. Therefore the genetic element that determines expression of Mta must be transmitted by the egg. Mta+ and Mta- lymphocytes, coexisting for months in lethally irradiated F1 mice reconstituted with a mixture of parental bone marrow cells, retained their Mta type. Thus Mta does not spread by infection.
Mta是一种在大多数小鼠品系中发现的母系传播的细胞表面抗原。它是不受限制的T杀伤细胞的靶标。在阳性和阴性母亲之间转移的所有49个胚胎,即使在受精后10 - 15小时这么早的时候,都发育成具有其原始母亲Mta类型的小鼠。因此,决定Mta表达的遗传元件必定由卵子传递。Mta +和Mta -淋巴细胞,在用亲本骨髓细胞混合物重建的致死性照射的F1小鼠中共存数月,保持它们的Mta类型。因此,Mta不会通过感染传播。
