title: WT_6_2
design: Transcriptome profiling of wild-type and PD-L1 knockout immortalized porcine alveolar macrophage (iPAM) cells following PRRSV-1 infection at 0 h, 6 h, and 48 h post-infection, with three biological replicates per condition, to investigate host transcriptional responses to viral infection and the role of PD-L1 in immune regulation.
