title: Formation of virus-like particles from O-type foot-and-mouth disease virus in insect cells using codon-optimized synthetic genes.
abstract: A recombinant baculovirus was constructed to simultaneously express codon-optimized virus-like particles (VLP), A VP1-2A-VP3 and VP0 of serotype O foot-and-mouth disease virus (FMDV), from individual promoters. The target proteins were expressed in insect cells at high level, as shown by indirect sandwich ELISA; and the expressed VP1-2A-VP3 could autocatalytically be cleaved into the individual proteins, VP1-2A and VP3, as shown by Western-blot analyses. In addition, in the insect cells, the structural proteins, VP0, VP3 and VP1-2A, self-assembled into virus-like particles resembling the authentic FMDV particles. This information should prove useful for the development of more efficient VLP assembly using shorter genes.
