In our current studies, we have used RSA59 infection in vivo, in vitro, and ex vivo as a model to understand whether MHV can directly infect CNS resident microglia and the mechanism of microglial activation in the induction of chronic demyelination. To confirm the RSA59-induced CNS inflammation, brain and spinal cord sections from day 7 (peak of inflammation) and day 30 (peak of demyelination) postinfected mice were stained with H&E or LFB and examined. While Iba1 immunofluorescence was observed in both gray and white matter, double fluorescence/immunofluorescence demonstrated dual labelling of EGFP (viral antigen) positive Iba1 positive microglia/macrophages were present only in the white matter of RSA59 infected mice (Figure 1 ). ./cache/cord-001017-4qfhltg4.txt ./txt/cord-001017-4qfhltg4.txt
