摘要

结果表明,质粒pUC19 DNA刺激CBA小鼠脾细胞体外增殖呈剂量依赖性。质粒DNA的刺激作用与COn A或LPS加和,与PMA协同,被非免疫原性磷酸二酯寡核苷酸和抗小鼠Ig抗体Fab片段抑制。这些数据和odn结合蛋白的亲和标记数据表明,免疫球蛋白受体参与了dna诱导的淋巴细胞活化。

Activation of spleen lymphocytes by plasmid DNA.

It was shown that plasmid pUC19 DNA stimulates in vitro proliferation of CBA mouse splenocytes in a dose-dependent manner. Stimulation effect of the plasmid DNA is additive with COn A or LPS, synergistic with PMA and is inhibited by nonimmunogenic phosphodiester oligonucleotides and Fab fragments of antimouse Ig antibodies. These data and the data of affinity labelling of ODN-binding proteins indicate that immunoglobulin receptors are involved in DNA-induced lymphocyte activation.
