A soluble factor (TRF) produced by mixtures of allogeneic mouse spleen, lymph node, and thymus cells functionally replaces T cells in a primary IgM antibody response to sheep blood cells in vitro. It is now shown that TRF can also reconstitute an IgG antibody response in T cell-deprived spleen cultures derived from preimmunized mice. The optimal time of addition and the amount of TRF required differ between primary and secondary in vitro systems.
由同种异体小鼠脾脏、淋巴结和胸腺细胞混合物产生的一种可溶性因子(TRF),在体外对绵羊血细胞的初次IgM抗体应答中,在功能上可替代T细胞。现已表明,TRF还能在源自预先免疫小鼠的无T细胞脾脏培养物中重建IgG抗体应答。初次和二次体外系统中TRF添加的最佳时间和所需量有所不同。
