Porcine neutrophils were left untreated (Figure 3T0) or were pre-treated with RPL39 siRNA, RPL9 siRNA, a TRP53 inhibitor, or a TRP53 activator before infection with GFP-labeled Salmonella for four (Figure 3T4) and eight hours hpt (Figure 3T8), during which intracellular Salmonella counts were monitored by flow cytometry. This evidence concerns the gene TP53 and infection.
