title: Response to hepatocarcinoma Hca-F of mice immunized with heat shock protein 70 from elemene combo tumor cell vaccine.
abstract: To analyze immune response to murine hepatocarcinoma Hca-F of mice immunized with heat shock protein 70 (HSP70) derived from elemene combo tumor cell vaccine (EC-TCV) of Hca-F, HSP70 was isolated from EC-TCV by ADP affinity chromatography. Mice were immunized with HSP70 intraperitoneally three times and spleen cells were sampled. For cells, their proliferation and cytotoxicity against Hca-F were measured with MTT assay and their phenotypes were analyzed with flow cytometry. Spleen cells of immunized mice with HSP70 exhibited more potent cytotoxicity against Hca-F and proliferation than that of normal control mice, but less potent than that of mice immunized with EC-TCV. Among three groups, the percent of gammadeltaT lymphocytes in the mice immunized with HSP70 (35.5%) was the highest compared with 6.25% in normal mice, and 28.4% in the mice immunized with EC-TCV. Immunization of HSP70 derived from EC-TCV could elicit potent immune response to Hca-F. HSP70 is one of elements inducing anti-tumor immune responses against Hca-F.
