• Porcine reproductive and respiratory syndrome virus (PRRSV) is known to infect and replicate preferentially in pulmonary alveolar macrophages (PAMs). We applied proteomic approaches to investigate the change in cellular proteins of PAMs infected with PRRSV in vitro. A total of 23 cellular proteins with significant alteration in different courses postinfection were identified. These proteins could be classified into the functions associated with morphogenesis, protein synthesis, metabolism, and stress response and ubiquitin-proteasome pathway. Of the altered proteins, two proteins, heat shock 27 kDa protein (HSP27) and superoxide dismutase 2 (SOD2), involved in stress response or ubiquitin-proteasome pathway were observed to be up-regulated. Our study is the first attempt to analyze the cellular protein profile of PRRSV-infected PAMs by proteomics and provide valuable information for better understanding the function alterations of PAMs induced by PRRSV infection.
