摘 要:To explore the anti-tumor effect of immunotherapy with recombinant protein vaccine based on FGFR-1 of chicken (cFR-1) in a mouse Meth A fibrosarcoma model, tumor volume and survival rate of the mice were observed at a 3-day interval. Microvessel density (MVD) was detected by immunohistochemistry. Auto-antibodies against self-FGFR-1 were detected by Western blotting and ELISA, respectively. The anti-FGFR-1 antibody-producing B cells (APBCs) were detected by enzyme-linked immunospot (ELISPOT) assay. Eighteen days after inoculation of tumor cells, the tumor volume was significantly smaller in cFR-l-immunized group than in mouse FGFR-1 (mFR-1) immunized group and normal saline (NS) control group (P〈0.05), and the survival time was significantly longer in cFR-l-immunized group than in the control groups (P〈0.01). MVD was significantly lower in cFR-l-immunized group than in mFR-1-immunized group and NS group (16.8 ±5.6 vs 64.6±1.8 and 59.6±8.7, P〈0.01). Antibodies against self-FGFR-1 were found in mFR-1-immunized group, the major antibody subclasses were IgG1 and IgG2b. Compared with the two control groups, the numbers of APBCs in cFR-l-immunized group were significantly increased (P〈0.01) These results demonstrated that the cFR-1-related anti-angiogenesis protein vaccine could induce the production of auto-antibodies against self-FGFR-1, which futher inhibit angiogenesis and growth of solid tumor.To explore the anti-tumor effect of immunotherapy with recombinant protein vaccine based on FGFR-1 of chicken (cFR-1) in a mouse Meth A fibrosarcoma model, tumor volume and survival rate of the mice were observed at a 3-day interval.
