The administration of interleukin-12 (IL-12) antibodies to Borrelia burgdorferi-infected C3H/HeN-scid mice increased the severity of acute Lyme arthritis. These results contrasted with the reduction of Lyme arthritis by IL-12 antibodies in immunocompetent animals. These data suggest that downregulation of innate immunity in SCID mice in the absence of B- and T-cell responses leads to an exacerbation of joint inflammation.
给感染伯氏疏螺旋体的C3H/HeN-scid小鼠注射白细胞介素-12(IL-12)抗体,会加重急性莱姆关节炎的严重程度。这些结果与免疫功能正常的动物中IL-12抗体减轻莱姆关节炎的情况形成对比。这些数据表明,在缺乏B细胞和T细胞反应的情况下,SCID小鼠固有免疫的下调会导致关节炎症加剧。
