To investigate changes in the levels of inflammatory factors, the CSF and blood of infected mice with EAE were assayed for IFN-γ, IL-4 IL-17A, IL-12p40, TNF-α, IL-6, MCP-1, IL-10, TGF-β, nerve growth factor (NGF) as well as NT3 and survivin concentrations on at Day 6 post-infection. This evidence concerns the gene IL4 and infection.
