Porcine reproductive and respiratory syndrome virus (PRRSV) non-structural protein (NSP)1 transcriptionally inhibits CCN1 and CCN2 expression by blocking ERK-AP-1 axis in pig macrophages in vitro

Porcine reproductive and respiratory syndrome virus (PRRSV) is a causative pathogen of PRRS that has generated a serious adverse impact on current global pork production. PRRSV primarily infects pig alveolar macrophages, but poor induction of innate immunity after infection often leads to more severe complications. Defining the functional role of each PRRSV non structural protein (NSP) within host cells might be helpful in understanding how...
