Specificity of the rat antibody against type II collagen was investigated using rat, bovine and human type II collagen preparations. PVG/c rats showed the highest antibody level in assays with autologous rat type II collagen than with heterologous (bovine or human) type II collagen even when immunized with heterologous one. On the other hand, the rat exhibited significantly low antibody response when they were immunized with autologous type II collagen. The results indicate that rats develop strong antibody response against self type II collagen when immunized with heterologous collagen and this unique specificity of anti-type II collagen antibody response suggests that autoimmunity is involved in the pathogenesis of collagen-induced arthritis in rats.
使用大鼠、牛和人II型胶原制剂研究了大鼠抗II型胶原抗体的特异性。即使使用异源(牛或人)II型胶原免疫,PVG/c大鼠在用自体大鼠II型胶原进行的检测中显示出的抗体水平也高于用异源II型胶原进行检测时的抗体水平。另一方面,当用自体II型胶原免疫时,大鼠表现出明显较低的抗体反应。结果表明,大鼠在用异源胶原免疫时会针对自身II型胶原产生强烈的抗体反应,这种抗II型胶原抗体反应的独特特异性表明自身免疫参与了大鼠胶原诱导性关节炎的发病机制。
