Using a panel of antibodies specific for H and L chain variable region subgroups, a panel of human monoclonal cold agglutinin (CA) and rheumatoid factor (RF) autoantibodies were analyzed. The vast majority of the two types of autoantibodies utilized VkIII L chains, many of which probably derive from the Humkv325 gene. However, while most RFs (77%) utilized VHI H chains, all the CAs used VHII subgroup H chains. These results are consistent with a model of autoantibody generation, wherein binding specificity is H chain defined in a set of antibodies that use a multipotential L chain.
利用一组针对重链和轻链可变区亚组的抗体,对一组人单克隆冷凝集素(CA)和类风湿因子(RF)自身抗体进行了分析。这两种自身抗体绝大多数使用VkIII轻链,其中许多可能源自Humkv325基因。然而,虽然大多数RF(77%)使用VHI重链,但所有CA都使用VHII亚组重链。这些结果与自身抗体产生模型一致,即在一组使用多能轻链的抗体中,结合特异性由重链定义。
