Abstract:

Porcine circovirus type 3 (PCV3) is an important emerging pathogen of swine disease, which has been reported in swine industry of several countries and regions since its discovery in 2015. Current understanding of PCV3 pathogenesis is limited. The majority of studies are focus on the retrospective investigation, genetic characterization, phylogenetic analysis and establishment of detection methods. PCVs-host relationship is close and complex, which involves various cellular and viral processes. The interaction between them determines cell fate and transmission and survival of PCVs. Recently, some researchers have conducted studies on the PCV3-host interaction at the virus component or whole virus level by utilizing transient expression system, clinical isolation and propagation and reverse genetics system. This review summarizes the recent progress on host response to viral infection, virus-host proteins interaction and viral life cycle, and could be helpful in understanding PCV3 pathogenesis.

Key words: porcine circovirus type 3, host response, viral life cycle
