The Prevention and Therapeutic Effects of Hsp70-Antigen Peptide Complexes on B16 Tumor Pulmonary Metastasis in Mice / 中国肿瘤生物治疗杂志

Objective: To explore the preventive and therapeutic effects of Hsp70-antigen peptide complexes (HACs) on pulmonary metastasis of malanoma B16 cells in mice. Methods: Antigen peptide mixtures were prepared from massive tumors and metastatic foci respctively, and bound with Hsp70 in vitro. The HACs were used to mice to prevent the formation of micrometastatic foci after the injection of B16 cells through tail vein, or treat the existent micrometastatic foci in lung The number of metastatic foci was counted and the cytotoxicity of splenocytes to B16 cells was determined. Results: After immunization with HACs, the number of metastatic foci in mice decreased significantly (P
