TLR 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.
