The Ly and Ia phenotypes of T lymphocytes involved in the in vitro generation of helper and suppressor cells were identified. The precursors of both cells are found in adult thymectomized spleen. Helper precursors are Ly-1+2-3-Ia-, while suppressor precursors are Ly-1-2+3+Ia-, although the suppressor effector is Ia+. In both cases a second 'amplifier' cell is required for differentiation of precursors to occur. This cell is found in anti-lymphocyte serum-treated spleen and has the phenotype Ly-1+2+3+Ia-.
确定了参与体外辅助细胞和抑制细胞生成的T淋巴细胞的Ly和Ia表型。两种细胞的前体均存在于成年去胸腺脾脏中。辅助细胞前体为Ly-1+2-3-Ia-,而抑制细胞前体为Ly-1-2+3+Ia-,尽管抑制效应细胞为Ia+。在这两种情况下,前体细胞的分化都需要第二种“放大”细胞。这种细胞存在于抗淋巴细胞血清处理过的脾脏中,其表型为Ly-1+2+3+Ia-。
