Nephritic changes of transgenic mice with high serum titer of anti-keratin autoantibody / 中华风湿病学杂志

ABSTRACT

Objective To analyze the autoimmune status of kidney in transgenic mice with high serum titer of anti-keratin autoantibody(AK auto Ab).Methods AK auto-Ab transgenie mice were set-up with conventional procedures,and the mice older than 20 weeks were selected for study.Urinary protein was quan- tified by Bradford method,and SDS-PAGE electrophoresis was used to analyze the type of proteinuria.Speci- mens of kidney were subjected to HE and PAS stain and immunofluorescence analysis and electrum microscopy observation were also performed.Results Compared with littcrmates,transgenie mice showed higher urinary proteins level(P
