In this report, we demonstrate that IL-4 is sufficient to stimulate both the proliferation and differentiation of Lyt-2+, Ia- splenic CTL precursors stimulated with the mitogenic lectin Con A. The response to IL-4 and Con A was not dependent on a putative endogenous production of IL-2 within the cultures, as demonstrated by an absence of an inhibitory effect by an anti-IL-2-R blocking mAb. Our results indicate that IL-2 and IL-4 can support an equivalent proliferative response by lectin-stimulated Lyt-2+ T lymphocytes, while IL-4 is more efficacious in stimulating their differentiation into mature cytolytically active cells.
在本报告中,我们证明白细胞介素-4(IL-4)足以刺激用促有丝分裂凝集素伴刀豆球蛋白A(Con A)刺激的Lyt-2⁺、Ia⁻脾细胞毒性T淋巴细胞(CTL)前体细胞的增殖和分化。如抗IL-2受体阻断单克隆抗体无抑制作用所示,对IL-4和Con A的反应不依赖于培养物中假定的内源性IL-2产生。我们的结果表明,IL-2和IL-4可支持凝集素刺激的Lyt-2⁺ T淋巴细胞产生同等的增殖反应,而IL-4在刺激它们分化为成熟的具有细胞溶解活性的细胞方面更有效。
