本文用ABC－ELISA法、免疫荧光法和3H－TdR掺入法对比研究了激活人淋巴细胞TfR表达与IL－2R表达的动态关系及与DNA合成的相关性。发现TfR和IL－2R的表达动态学具有相似性淋巴细胞处于静息状态时未能检TfR／IL－2R，而受PHA激活后IL－2R的表达（培养后12h）早于TfR表达（培养后19h），两者均在66～72h达高峰，以后渐下降。TfR和IL－2R的表达及它们与DNA合成均存在直线相关关系（rTfR，IL-2R＝0．965，rTfR，DNA＝0．901，rIL-2R＝0．946，P值均小于0．05）。 In this study, the dynamic relationship between TfR expression and IL-2R expression in activated human lymphocytes and the correlation with DNA synthesis were studied by ABC-ELISA, immunofluorescence and 3H-TdR incorporation. TfR and IL-2R expression kinetics were found to be similar TfR / IL-2R was not detected at rest in lymphocytes, whereas IL-2R expression was earlier than TfR expression at 12 h after PHA activation (culture After 19h), both reached a peak at 66 ~ 72h, then gradually decreased. There was a linear correlation between TfR, IL-2R and their DNA synthesis (rTfR, IL-2R = 0.965, rTfR, DNA = 0.901, rIL-2R = 0.946, P values ​​were less than 0). 05).
