Figure 5From: Comparative expression of Toll-like receptors and inflammatory cytokines in pigs infected with different virulent porcine reproductive and respiratory syndrome virus isolatesTLR mRNA expression in porcine PAMs (A) and cerebral medullar tissues (B) determined by real-time PCR. PAMs and cerebral medullar tissues were collected at necropsy conducted at 15 d.p.i. (*) indicates a significant difference (p < 0.05) between groups. Data are presented as means (± SEM) generated from 6 pigs in the LP, LP-der, and control groups or 4 pigs in group HP.Back to article page
