In limiting dilution analysis, the absolute frequencies of lipopolysaccharide-reactive B cell precursors producing anti-trinitrophenyl antibodies or the MOPC460 idiotype were studied in BALB/c mice, either normal, or immunized with antigen (Ab1), the idiotype (Ab2), or a monoclonal anti-idiotype antibody (Ab3). Anti-idiotype immunity results in the suppression of the B cell precursors for the relevant idiotype, and anti-(anti-idiotype) immunity leads to a 10-fold increase in precursor B cell frequencies, with a comparatively lower increase in antibody-producing precursors. The findings can only be explained by variations in the composition of the B cell compartment in the various immune states.
在有限稀释分析中,研究了正常或用抗原(Ab1)、独特型(Ab2)或单克隆抗独特型抗体(Ab3)免疫的BALB/c小鼠中产生抗三硝基苯抗体或MOPC460独特型的脂多糖反应性B细胞前体的绝对频率。抗独特型免疫导致相关独特型的B细胞前体受到抑制,而抗(抗独特型)免疫导致前体B细胞频率增加10倍,产生抗体的前体增加相对较少。这些发现只能通过不同免疫状态下B细胞区室组成的变化来解释。
