已知CD 5 +B淋巴细胞(B1 a)群体参与对微生物TI抗原的大多数免疫应答。此外,已知缺乏针对TI-2抗原的免疫应答的xid小鼠缺乏B1 a群体,这表明B1 a细胞在TI-2免疫应答中的作用。我们以前建立了寡糖人血型A抗原刺激小鼠TI-2免疫应答。在这项工作中,我们表明,抗A分泌杂交瘤的频率较高的小鼠脾B1 a人口和体内抗CD 5治疗减少抗A免疫反应,而不影响对TD RBC抗原的反应。通过体外抗CD 5处理脾细胞观察到类似的效果。体内抗CD 5治疗也干扰了脾细胞数量的免疫依赖性增加。这些结果与B细胞CD 5受体在TI-2免疫应答的调节中可能通过其与CD 72配体的相互作用介导的重要作用一致。
The CD5+B lymphocyte (B1a) population is known to be involved in most immune responses to microorganism TI antigens. Moreover, xid mice deficient for immune responses against TI-2 antigens are known to lack the B1a population, suggesting a role for B1a cells in TI-2 immune responses. We previously established that the oligosaccharide human blood group A antigen stimulated murine TI-2 immune responses. In this work, we show that the frequency of anti-A-secreting hybridomas was higher in mice with larger splenic B1a populations and that in vivo anti-CD5 treatment reduced anti-A immune response without affecting the response against TD RBC antigens. A similar effect was observed by in vitro anti-CD5 treatment of splenocytes. The in vivo anti-CD5 treatment also interfered with the immunization-dependent increase in splenocyte numbers. These results are in agreement with an important role for the B-cell CD5 receptor in the regulation of TI-2 immune responses possibly mediated by its interaction with the CD72 ligand.
