Abstract

Analyses of cell surface determinants of splenocytes from copper-deficient C58 mice indicate alterations in lymphocyte subpopulation characteristics. Both the absolute number and the relative percentage of surface immunoglobulin-bearing (B) cells from copper-deficient mice were significantly greater than those from copper-supplemented controls. The relative percentage of Thy 1.2-positive (T) cells was decreased, and the decrease was most prominent within the Lyt 1-positive (helper) T-cell subset. The functional responsiveness of both B cells and T cells was decreased in copper deficiency.

摘要

对缺铜C58小鼠脾细胞的细胞表面决定簇分析表明淋巴细胞亚群特征发生改变。缺铜小鼠表面带有免疫球蛋白的(B)细胞的绝对数量和相对百分比均显著高于补铜对照组。Thy 1.2阳性(T)细胞的相对百分比降低,且在Lyt 1阳性(辅助)T细胞亚群中降低最为显著。缺铜时B细胞和T细胞的功能反应性均降低。
