Gene expression profiles for porcine alveolar macrophage isolated from piglets injected with Mab followed by challenge with two PRRSV strains: PRRSV-JXA1 and PRRSV-HNhx

An PRRSV specific IgG-type Mab-PN9cx3, demonstrated broad recognition and neutralization activity against both PRRSV-1 and PRRSV-2 isolates in vitro, was tested for in vivo protection experiments. Administration of Mab-PN9cx3 20mg in piglets significantly alleviated the pathological changes in lungs and decreased virus loads in PAMs after challenging with two heterogenous PRRSV isolates: HP-PRRSV-JXA1 and PRRSV NADC-30 like HNhx when compared with piglets inoculated virus . Transcriptome profile for porcine alveolar macrophage of different groups were analyzed via RNA-sequencing. Overall design: PAMs isolated from different groups (n=3) were harvested by TRIzol for RNA extraction and subjected to RNA-sequencing
