After 48 h of infection (Figure 3B and C), MVA-B induced higher production of IL-7, IL-15, MCP-1/CCL2 and MIG/CXCL9 than uninfected MDDC, indicating that some mediators are secreted at later times post-infection and/or at low doses possibly because is necessary some degree of maturation to up regulate such mediators. This evidence concerns the gene IL15 and infection.
