Effect of dexamethasone on the expression of
mRNAs for the cytokines IFN-γ, TNF-α, and IL-6 and chemokines
MIP-1β and mob-1 in BDV-infected rat brains. Total RNA
was subjected to RT-PCR by using gene-specific primers, and the
amplified DNA was analyzed by Southern blotting as described in
Materials and Methods. CTR, brain RNA from normal
uninfected rats; BDV, brain RNA from BDV-infected rats at days 17 and
22 postinfection; +Dexamethasone, brain RNA from dexamethasone-treated
rats.
