Abstract

Skin biopsies were performed on female (NZB X NZW)F1 mice (B/W) at ages ranging from 1 to 12 months. The control strain was the C57B1/6. Immunoglobulin G and beta 1C globulin deposition was sought using the indirect immunofluorescence method. Both globulins were detected consistently at the dermal-epidermal junction from the age of 6 months. The pattern of staining was granular, and progressed from focal deposition to confluent and diffuse involvement of the basement membrane at 9-10 months of age. No staining was observed in any of the C57B1/6 mice up to 14 months of age. These findings increase the resemblance of B/W disease to human systemic lupus erythematosus.

摘要

对1至12月龄的雌性(新西兰黑鼠×新西兰白鼠)F1小鼠(B/W)进行皮肤活检。对照品系为C57B1/6。采用间接免疫荧光法检测免疫球蛋白G和β1C球蛋白沉积。从6月龄起,在真皮-表皮交界处始终能检测到这两种球蛋白。染色模式为颗粒状,在9至10月龄时从局灶性沉积发展为基底膜的融合性和弥漫性累及。在14月龄之前,任何C57B1/6小鼠均未观察到染色。这些发现增加了B/W疾病与人类系统性红斑狼疮的相似性。
