Abstract:

Epitope polypeptides of peste des petits ruminants virus (PPRV) were synthesized and its immunogenicity was examined in mice.Four epitope polypeptides against F and H gene of PPRV were selected by the epitope prediction software and acquired by chemical synthesis,then were administered subcutaneously at dose of 100 μg to BALB/c mice,and the epitope antigenicity was analyzed by immunoassays of ELISA,MTT,the killing activity of NK cell and T lymphocyte subsets detection.As a result,H242-255,F528-541 and H349-362 had better humoral immune function among the four epitope polypeptides,while H242-255 and H392-405 had better cellular immune function.Thus,peptide of H242-255 can satisfy the two immunologic functions,and can be used as a candidate epitope vaccine component.The study had great significance by screening efficient epitopes for the development of PPRV epitope vaccines.
