Four patients with common, variable agammaglobulinemia were preveiously reported to have normal numbers of circulating B lymphocytes which synthesized normal amounts of IgG in tissue culture but failed to secrete the newly synthesized IgG. The B lymphocytes of these patients fail to incorporate [3H]mannose and/or [3H]glucosamine into newly synthesized IgG, whereas such incorporation appears to occur just before IgG secretion in cultures of normal B lymphocytes.
先前报道,4例普通变异型无丙种球蛋白血症患者循环B淋巴细胞数量正常,这些细胞在组织培养中合成正常量的IgG,但无法分泌新合成的IgG。这些患者的B淋巴细胞不能将[3H]甘露糖和/或[3H]氨基葡萄糖掺入新合成的IgG中,而在正常B淋巴细胞培养物中,这种掺入似乎恰好在IgG分泌之前发生。
