Addition of 40 microM 2'deoxyguanosine (2'd Guo) results in enhancement of human lymphocyte cultures stimulated with pokeweed mitogen, assessed by staining intracytoplasmic immunoglobulins. Furthermore, B cell responses were enhanced under experimental conditions favouring T cell suppression rather than help. Experiments with enriched B cell fractions indicate that 2'dGuo does not directly stimulate B cell responses. The enhancement by 2'dGuo was still observed in the presence of irradiated (non-proliferating) T cells. The mechanism of enhancement by 2'dGuo is discussed in terms of its effect on proliferation-independent suppressor T cells.
添加40微摩尔的2'-脱氧鸟苷(2'd Guo)可增强经商陆有丝分裂原刺激的人淋巴细胞培养物,这是通过对细胞质内免疫球蛋白进行染色来评估的。此外,在有利于T细胞抑制而非辅助的实验条件下,B细胞反应得到增强。对富集的B细胞组分进行的实验表明,2'dGuo不会直接刺激B细胞反应。在存在经辐照(不增殖)的T细胞的情况下,仍可观察到2'dGuo的增强作用。根据其对不依赖增殖的抑制性T细胞的作用,讨论了2'dGuo的增强机制。
