Fig. 1. Post-vaccination gene expression levels of TNF-a, IL-6, IFN-g and IL-10 in the BAL fluid of vaccinated (A, B and D groups) and non-vaccinated control
(C) pigs. Data are reported as relative (RQ: relative quantification) values normalized to GAPDH gene expression levels (mean values standard deviation).
The asterisk refers to statistically significant differences between groups; p < 0.05.
