Golden-star nanoparticles as adjuvant effectively promotes immune response to foot-and-mouth disease virus-like particles vaccine.

Authors: Teng Z, Sun S, Chen H, Huang J, Du P, Dong H, Xu X, Mu S, Zhang Z, Guo H Abstract Virus-like particles (VLPs) have become a hot topic in modern vaccine research because of its safety, facile production, and immune properties. To further enhance the immune effect of VLPs, we synthesized and used gold-star nanoparticles (AuSNs) as adjuvant for vaccine. Foot-and-mouth disease (FMD) VLPs as target antigen were combined with AuSNs. The FMD VLPs-AuSNs complex was characterized through sodium dodecyl sulfate-polyacrylamide gel electrophoresis, Western blot, ultraviolet light absorption, and morphological measurement analyses. Result indicated that the FMD VLPs-AuSNs complex is non-toxic in different cell lines. AuSNs can effectively promote the entry of FMD VLPs into cells and im...
