摘要: Porcine reproductive and respiratory syndrome (PRRS) is an economically devastating viral disease of pigs. Safer and more effective vaccines are urgently needed. In this study, a synthetic ORF5 gene of porcine reproductive and respiratory syndrome virus (PRRSV) was adsorbed onto poly(D, L-lactide-co-glycolide)/polyethylenimine (PLGA/PEI) nanoparticles. We prepared a PLGA-nanoparticle-adsorbed PRRSV DNA vaccine and a PEI-DNA complex. The results showed that these model vaccines could significantly enhance humoral and cellular immune responses when compared with the responses induced by pcDNA3.1-SynORF5, a plasmid construct for expression of PRRSV ORF5. PLGA-branched PEI nanoparticles induced the most efficient immune response. The delivery system and adjuvant provide new models for the development of vaccines against PRRSV.
