Proinflammatory cytokine and chemokine genes are highly expressed in NPTr epithelial cells infected by S. suis and swine influenza virus. Expression of TNF, IFN-β, IFNλ1, IL-1, IL-6, IL-8, VCAM-1, CCL5, PLAU, and COX-2 genes in NPTr cells infected with S. suis, H1N1, or S. suis/H1N1 when compared to mock-infected cells, as quantified by qPCR assay. Data represent mean relative expression values of mRNA ± SEM. Groups that are significantly different are indicated by different letters (a, b, and c), as determined by One-way ANOVA with p ≤ 0.05.
