Autoantibodies against mouse FGFR-1 were identified by Western blot analysis and ELISA. Compared with the two control groups, the number of APBCs, which were detected by ELISPOT assay, was significantly in- creased in the spleens of mice immunized with cFR1 （P〈0.05）. IgG1 and IgG2b, which were detected by ELISA, were the major subclasses and were substantially increased in response to chicken FGFR-1 when compared with control group. The recombinant chicken FGFR-1 protein used as a vaccine can induce autoantibodies against self-FGFR-1 in mice and provide a basis for the active immunotherapy of tumor angiogenesis.展开更多
