“转移因子”(TF)一词系指从对抗原敏感个体的白细胞中抽提的低分子量(小于12,000道尔顿)分子,这些分子似可将特异敏感性授予未接触过此种抗原的受体。因此,这种现象所包含的本质是,把抗原和供体免疫活性细胞特异性相互作用所得到的物质,被动转移给原先缺乏明显敏感性的受体。这 The term “transfer factor” (TF) refers to molecules of low molecular weight (less than 12,000 daltons) extracted from leukocytes of antigen-sensitive individuals that may be able to confer specific sensitivities to subjects not exposed to such antigens body. Therefore, the essence of this phenomenon is the passive transfer of substances resulting from the specific interaction between the antigen and the immunocompetent cells of the donor to recipients that previously lacked appreciable sensitivity.
