Specifically purifed anti-human delta stimulated the in vitro incorporation of [3H]thymidine by human peripheral lymphocytes from patients with chronic lymphocytic leukaemia (CLL). The peak response varied between individuals; those with 5--52% IgD-bearing lymphocytes exhibited maximum stimulation at 3 days, whereas a patient with only 1% IgD-bearing cells showed optimal activation at 6 days. In agreement with others, our data indicated that, in most instances, lymphocytes from patients with CLL respond poorly to PHA. One of the most important findings in this study is the enhancement of PHA responsiveness by anti-delta. Lymphocytes that exhibited reduced responsiveness to PHA alone, when pre-treated with anti-delta, showed transformation greater than the sum of the anti-delta plus PHA responses.
特异性纯化的抗人δ抗体刺激了慢性淋巴细胞白血病(CLL)患者外周血淋巴细胞在体外对[3H]胸腺嘧啶核苷的掺入。峰值反应在个体间有所不同;携带IgD淋巴细胞占5% - 52%的患者在3天时表现出最大刺激,而携带IgD细胞仅占1%的一名患者在6天时显示出最佳激活。与其他人的研究结果一致,我们的数据表明,在大多数情况下,CLL患者的淋巴细胞对PHA反应较差。本研究中最重要的发现之一是抗δ抗体增强了PHA反应性。单独对PHA反应性降低的淋巴细胞,在用抗δ抗体预处理后,其转化程度大于抗δ抗体加PHA反应的总和。
