Pseudorabies is a highly contagious viral disease caused by the pseudorabies virus (PRV), and it is one of the most devastating diseases for the swine industry worldwide. However, the host-virus interaction and virus-related host factors at the mRNA level in virus natural host (pig) cells, are not fully understood. Here, we performed time-course RNA sequencing of the PK-15 cells infected with a recombinant strain PRV-Becker-GFP to study the dynamic competition between the host and the virus. At early stage of infection (3 hpi), our results suggested that the activation of cytosolic DNA-sensing pathway and NOD-like receptor signaling pathway might play a role in recognition of PRV, and the activation of NF-kappa B signaling pathway and TNF signaling pathway might be involved in immune response against the virus. However, all these pathways were subsequently inhibited by PRV. Additionally, our data indicated the fatty acid degradation pathway was significantly downregulated during late stage of infection (9 hpi), which was likely to accumulate fatty acids for viral envelope synthesis. Moreover, we verified the expression of 5 representative genes (ALDH1B1, ACAA2, ACSL3, ADH5, and EHHADH) related to fatty acid degradation pathway by RT-qPCR. Overall, our findings provide valuable information to better understand host-virus interactions and the immune escape mechanism of PRV-Becker as a virulent strain, offering novel targets for porcine anti-PRV breeding research and potential clinical treatment.
