An immunoglobulin G based chimeric protein induced foot-and-mouth disease specific immune response in swine
2000
Abstract Epitopes containing the residues 141aa–160aa and 200aa–213aa from foot-and-mouth disease (FMD) serotype O1K HK type FMDV VP1 were joined to a swine immunoglobulin G single heavy chain constant region (scIgG), creating a novel chimeric protein, named F1-scIgG. In this study, inoculation with F1-scIgG induced both FMD virus-neutralizing antibody response and T cell response in swine. Antisera from these F1-scIgG-inoculated swine protected suckling mice against 1000 lethal dose 50 (1000LD 50 ) FMD challenge. F1-scIgG-inoculated swine were also fully protected against 50LD 50 FMD virus challenge. The present study demonstrates the clear potential for viral epitopes linked with self-Ig in novel FMD vaccine design.
