Abstract:
Objective: To establish an experimental autoimmune encephalomyelitis (EAE) model in C57BL/6 mice, providing a basis for studying the immunopathological mechanism and experimental therapy of multiple sclerosis. Methods: Twenty-five C57BL/6 mice were immunized with both 300μg MOG35-55 in complete Freund's adjuvant (CFA) and 109/ml Bordetella pertussis vaccine (BPV) to establish EAE model. Mice in adjuvant group (n=8) were treated with CFA, BPV and normal saline; mice in control group (n=7) were treated with normal saline. The pathologic changes of the central nervous system were studied by H-E staining and Luxol Fast Blue (LFB) staining. Results: The clinic symptoms of EAE were present in 22 mice in model group since the 11th day post-immunization, with the incidence being 88%. There was no evident EAE symptom in CFA group and control group. Light microscopy showed there were abundant inflammatory cells infiltrated in the cerebral and spinal cord tissues in EAE mice, with evident demyelination in white matter. Conclusion: This method is easy to be carried out; the model established by it is stable and worth popularizing.
