Analysis of the B and T cell response in guinea pigs induced with recombinant vaccinia expressing foot-and-mouth disease virus structural proteins
Recombinant vaccinia viruses expressing foot-and-mouth disease virus (FMDV) P1 and VP1 genes have been used to study the immune response induced by these vital polypeptides in guinea pigs. Anti-FMDV antibodies, but not neutralizing activity, were detected in the sera from immunized animals. The results indicate that both CD4+ and CD8+ FMDV-specific T cells were induced by the vaccinia recombinants. Consistently with the activation of CD4+ T cells, lymphocytes from immunized animals specifically proliferated in vitro in response to whole virus. The induction of virus-specific CD8+ T cells was determined by CTL assay of immune splenocytes restimulated in vitro with FMDV infected cells. Altogether, the results obtained indicate that both B and T cell immune responses to FMDV are elicited upon immunization of guinea pigs with vaccinia recombinants expressing FMDV structural polypeptides.
