The homology modeling suggested the position between G85 and S86 of the PCV2 Cap is an ideal insertion site for GP5 epitope B.
The PCV2 chimeric VLPs from recombinant Cap was successfully generated.
The PCV2 chimeric VLPs retain the capacity of entry into PK-15 cells.
The PCV2 chimeric VLPs are capable of inducing strong humoral and cellular immune responses in mice.
The PCV2 chimeric VLPs provide a new platform to develop a bivalent or multivalent vaccine.
