The present study demonstrates that the opsonising antibody titres mediating enhanced IFN-α responses in pDC were similar to neutralizing titres, when antigenically related viruses from the same serotype were employed. Considering the possible importance of opsonising antibodies and pDC in the protection against FMDV, the main aim of this study was to characterize the relationship between neutralizing and opsonising activities of polyclonal sera from immunized pigs.
