Abstract

Objective To establish an experimental autoimmune encephalomyelitis (EAE)model in female C57BL/6 mice aged 6-8 weeks and investigate its disease phenotype so as to build a better animal model of multiple sclerosis (MS). Methods The EAE model was established in 50 female C57BL/6 mice through intradermal injection of myelin oligodendrocyte glycoprotein 35-55 peptide. We assessed the disease progression daily according to a 15-point score for 90 days, and further observed the brain lesions in terms of pathology. Results There were three courses of disease in the EAE model: chronic course (3 mice), relapse and remission course (7 mice) and monophasic course (11 mice). Interestingly, we identified some mice (28 mice) had changes in coat color, mental and motor activity, as well as inflammatory demyelinating lesions in the brain tissue although their neurological functions were scored as 0 point. Conclusion The EAE model in C57BL/6 female mice shows disease phenotype similar to multiple sclerosis and can be used as a good animal model.
