Expression levels of inflammatory cytokines in the magnum and uterus of laying hens infected with NDV. IL-1β/2/6 and IFN-α/β were quantified using SYBR Green-based RT-PCR. Panels a, b, c, d and e depict results for IL-1β, IL-2, IL-6, IFN-α, and IFN-β, respectively, in the magnum and uterus. Statistical analysis was performed by comparison with uninfected chickens. *P <0.05, **P <0.01, ***P <0.001
