我们研究了人白细胞表面糖蛋白CD 45(以前称为白细胞共同抗原或T200)在用促肿瘤的佛波醇二酯激活外周T细胞后的磷酸化。将细胞与[32 P]正磷酸盐孵育,用佛波醇二酯处理,并使用单克隆抗体T29/33免疫沉淀CD 45。CD 45在未活化的T细胞中弱磷酸化,但用10,60或200 nM佛波醇12,13-二丁酸酯(PDBu)处理细胞显著增加了糖蛋白的磷酸化。PDBu的这种作用对于CD 45是相对选择性的,因为细胞的活化不影响所有膜磷酸糖蛋白的磷酸化。另一种肿瘤促进剂佛波醇12-肉豆蔻酸酯13-乙酸酯(PMA)的作用与PDBu相当,但非肿瘤促进的佛波醇衍生物4α-佛波醇12,13-二癸酸酯没有改变CD 45磷酸化水平。发现用60 nM PDBu处理T细胞仅30 s后,CD 45的磷酸化明显增加,并且磷酸化在约5 min内达到最大值。
We have studied the phosphorylation of the human leukocyte surface glycoprotein CD45, formerly known as leukocyte common antigen or T200, following activation of peripheral T cells with tumor‐promoting phorbol diesters. The cells were incubated with [32P]orthophosphate, treated with phorbol diesters, and the CD45 was immunoprecipitated using the monoclonal antibody T29/33. CD45 was weakly phosphorylated in nonactivated T cells, but a treatment of the cells with 10, 60 or 200 nM phorbol 12,13‐dibutyrate (PDBu) markedly increased the phosphorylation of the glycoprotein. This effect of PDBu was relatively selective for CD45 since the activation of the cells did not affect the phosphorylation of all membrane phosphoglycoproteins. The effect of another tumor promoter, phorbol 12‐myristate 13‐acetate (PMA), was comparable to that of PDBu, but a nontumor‐promoting phorbol derivative, 4α‐phorbol 12,13‐didecanoate, did not change the level of CD45 phosphorylation. The phosphorylation of CD45 was found to clearly increase after a treatment of T cells with 60 nM PDBu for only 30 s, and the phosphorylation reached its maximum in about 5 min.
