摘要：Antiviral innate immunity plays a central role at the early stage of viral life cycles. The highly pathogenic porcine reproductive and respiratory syndrome virus (HP-PRRSV) is a major concern for the swine industry and causes high degrees of morbidity and mortality. The intracellular signalling cascades of the innate immune system triggered by HP-PRRSV often lead to the elim- ination of infection. However, HP-PRRSV induces pathological changes and can cause aberrant immune responses in the host, resulting in acute lung injury and immune dysfunction. Studies of the innate immune responses to HP-PRRSV infection are crucial to gaining insight into HP-PRRSV- induced pathogenesis and for the development of novel protective vaccines. In this review, we discuss the innate immune responses against HP-PRRSV infection and suggest new areas of investigation into this important interface between pathogen and host.
