Porcine reproductive and respiratory syndrome (PRRS) is an epidemic animal infectious disease worldwide. In our previous research it was suggested that matrine could inhibit PRRSV infection both in vitro and in vivo, but the antiviral mechanisms are still undecided. Network pharmacology can well solve the difficult problem of “multiple targets, multiple pathways” in the research of TCM action targets. The results of network pharmacology indicated that matrine exerts its anti-PRRSV effect by targeting HSPA8 and HSP90AB1. The results of real-time fluorescent quantitative PCR and western blot showed that infection with PRRSV induced a significant increase in the expression of HSPA8 and HSP90AB1 whereas matrine treatment could significantly reverse it, and the number of viruses of PRRSV also decreased. In this study, the method of network pharmacology was used to explore HSPA8 and HSP90AB1 which were the potential targets of matrine against PRRSV on Marc-145 cells.

Because mathematics, physics, and chemistry have already been broadly applied in the practice of production, people generally have a better understanding of their content and applicability. On the other hand, many people are still very unfamiliar with the field of anthropometry. What does this discipline study? Of what use is it? In many cases, people know nothing at all about it.
