The proportion of peripheral blood lymphocytes with cell surface b5 immunoglobulin (Ig) was compared with serum b5 Ig levels in allotype-suppressed and recovering b5 homozygous rabbits in order to establish the cellular defect in suppression and to determine the relation between lymphocyte membrane Ig and secreted Ig of the same allotype. In rabbits fully suppressed for b5, the absence of circulating b5 Ig is reflected in a complete deletion of b5-bearing lymphocytes. During spontaneous escape from suppression, the appearance of b5-bearing lymphocytes precedes the appearance of detectable serum b5. During recovery from suppression b5-bearing lymphocytes recover rapidly toward normal levels, but circulating b5 levels remain chronically and disproportionately depressed.
比较了同种异型抑制和恢复中的b5纯合兔外周血中具有细胞表面b5免疫球蛋白(Ig)的淋巴细胞比例与血清b5 Ig水平,以确定抑制中的细胞缺陷,并确定淋巴细胞膜Ig与相同同种异型的分泌型Ig之间的关系。在b5完全被抑制的兔子中,循环b5 Ig的缺失反映在携带b5的淋巴细胞完全缺失。在自发从抑制状态逃脱的过程中,携带b5的淋巴细胞的出现先于可检测到的血清b5的出现。在从抑制状态恢复的过程中,携带b5的淋巴细胞迅速恢复到正常水平,但循环b5水平长期且不成比例地保持在低水平。
