Figure 4. Immune responses of CiIFN1/3 to plasmids containing CpG ODNs.
Left, the mRNA expressions of CiIFN1 (A) and CiIFN3 (B) were measured at 24 and 48 h post-infection. CIK cells were stimulated with PBS (control) or plasmids containing CpG ODNs and infected with GCRV. Other captions were the same as Figure 3. Right, CIK cells were co-transfected with 800 ng of pRL-TK and IFN1pro-luc (A) or IFN3pro-luc (B) in 24-well plates. At 16 h post-transfection, the cells were stimulated with PBS (control) or plasmids and infected with GCRV for 16 h or uninfected. Dual luciferase reporter assays were conducted at 12 h after GCRV infection. Treatment durations in this assay was far shorter than those in qRT-PCR which caused different results. Error bars indicate standard deviation (n = 4). Asterisks indicate significant difference from control (*, P ≤ 0.05).
