TLR2-mediated NF-κB signaling pathway is involved in PPV1-induced apoptosis in PK-15 cells.

ABSTRACT: Porcine parvovirus 1 (PPV1) mainly induces severe reproductive failure in pregnant swine, and causes huge economic losses to the swine industry. Cell apoptosis induced by PPV1 infection has been identified the major cause of reproductive failure. However, the molecular mechanism was not fully elucidated. In this study, the potential mechanism of PPV1 induced apoptosis in PK-15 cells was investigated. Our results showed that PPV1 induced apoptosis in PK-15 cells. Further studies revealed toll-like receptor 2 (TLR2) was involved in the PPV1-mediated apoptosis. TLR2 siRNA significantly decreased the apoptosis. Finally, our study showed NF-κB was activated by TLR2 during PPV1-induced apoptosis. The activation of NF-κB signaling was demonstrated by the phosphorylation of p65, p65 nuclear transl
