In 50 old donors antibody synthesis has been detected using a protein A haemolytic plaque assay. Data provide evidence that the plaque forming cell (PFC) capacity of aged peripheral mononuclear cells (PBMC) is significantly depressed (0 . 01 greater than P greater than 0 . 001) in comparison to controls. Additionally, suppression is mediated by adherent cells, since monocyte depleted lymphocytes regain the ability of generating spontaneous plaques. The inhibitory effect of monocytes seems to be prostaglandin-dependent, since indomethacin pre-treated PBMC give rise to a normal number of plaques when compared to young mononuclear cells.
在50名老年供体中，通过蛋白A溶血空斑试验检测到了抗体合成。数据表明，与对照组相比，老年外周血单个核细胞（PBMC）的空斑形成细胞（PFC）能力显著降低（0.01＞P＞0.001）。此外，抑制作用由黏附细胞介导，因为去除单核细胞的淋巴细胞恢复了产生自发空斑的能力。单核细胞的抑制作用似乎依赖于前列腺素，因为与年轻单核细胞相比，吲哚美辛预处理的PBMC产生的空斑数量正常。
