Abstract

Subpopulations of human peripheral blood leucocytes were isolated by nylon filtration or E-rosette separation and tested for functional activity. As shown previously, zinc ions induce DNA synthesis in unfractionated lymphocyte cultures. E-rosette-forming cells (E-RFC), obtained either by nylon wool filtration or E-rosette separation, responded well to PHA but showed only low levels of proliferative reactivity to zinc and Con A. These dminished responses could be completely restored by the addition of small numbers of autologous, mitomycin-treated monocytes; further experiments suggested that a monocyte-derived soluble factor can substitute for monocytes in this function. B lymphocyte-enriched cell populations, containing less than 1% E-RFC, did not respond to zinc and showed only marginal reactivity to PHA and Con A.

摘要

通过尼龙过滤或E花环分离法分离人外周血白细胞亚群，并检测其功能活性。如先前所示，锌离子可诱导未分级淋巴细胞培养物中的DNA合成。通过尼龙棉过滤或E花环分离获得的E花环形成细胞（E-RFC）对PHA反应良好，但对锌和刀豆球蛋白A的增殖反应水平较低。加入少量经丝裂霉素处理的自体单核细胞可完全恢复这些减弱的反应；进一步的实验表明，单核细胞衍生的可溶性因子可在该功能中替代单核细胞。富含B淋巴细胞的细胞群体，其E-RFC含量低于1%，对锌无反应，对PHA和刀豆球蛋白A仅表现出微弱反应。
