MP4- and MOG:35-55-induced EAE in C57BL/6 mice differentially targets brain, spinal cord and cerebellum.

摘要

Mechanism-oriented studies of EAE rely mostly on gene-modified mice on the C57BL/6 background. Here we report that MP4-induced EAE displays characteristic differences in CNS pathology as compared to MOG peptide 35-55-elicited disease. While in the latter, the topology of CNS infiltration remained unchanged throughout the disease, in MP4-induced EAE it was dynamic and stage-dependent shifting from the brain to the spinal cord and finally to the cerebellum. Unlike in the MOG peptide model, the frequencies and sizes of CNS lesions in MP4-induced disease showed a clear correlation with clinical disease severity. These characteristic features of MP4-induced EAE may contribute to modelling the complex spectrum of disease manifestations seen in MS.
