Totally synthetic peptide-based immunocontraceptive vaccines show activity in dogs of different breeds
چکیده انگلیسی

In this study we examine the immunogenicity of totally synthetic peptide-based immunocontraceptive vaccines in dogs. Seven individual epitope-based vaccines were assembled in which a different T helper (TH) cell epitope derived from the sequence of F protein of canine distemper virus was synthesized in tandem with a peptide representing luteinising hormone releasing hormone (LHRH). Each of the individual TH–LHRH peptide vaccines was inoculated subcutaneously into dogs. The results demonstrate that five of the seven peptide vaccines were able to elicit strong anti-LHRH antibody responses in beagle foxhounds accompanied by a concomitant suppression in the levels of the hormones testosterone and progesterone in the majority of the animals. A pool of these five peptides was then used to inoculate five different breeds of dogs. All animals responded with high levels of anti-LHRH antibody. An investigation of the proliferative responses of peripheral blood mononuclear cells (PBMC) obtained from inoculated dogs showed that the majority of breeds responded to each of the individual T helper cell epitope tested. The results provide a strategy for development of an immunocontraceptive vaccine for use in multiple breeds of dogs.
