Abstract

Th1 antigen-specific T cells secrete interferon-γ, which is able to kill antigen-specific cancer cells and is helpful for cancer vaccines. The aim of the present study was to explore whether B16 cell lysates plus polyinosinic-cytidylic acid (poly I:C) can effectively inhibit the progression of melanoma in an animal model. In the present study, C57BL/6 mice were divided into three groups, with each group containing more than six mice. The groups of mice were immunized twice with B16 cell lysates plus poly I:C, B16 cell lysates, or phosphate-buffered saline only, respectively. The in vivo results demonstrated that splenocytes from the mice immunized with B16 cell lysates plus poly I:C contained higher percentages of CD3+CD8+ T lymphocytes and CD3+CD4+ T lymphocytes, which were detected by a fluorescence-activated cell sorter, and produced higher levels of antigen-specific splenocyte proliferation activity, as detected by MTT assay. The splenocytes from the mice immunized with B16 cell lysates in combination with poly I:C produced higher levels of interferon‑γ, as detected by quantitative polymerase chain reaction and ELISA, as well as cytotoxic T lymphocyte activity when stimulated in vitro with B16 lysates. Additionally, subcutaneous immunization of the C57BL/6 mice with B16 cell lysates plus poly I:C conferred greater protection against tumor-forming B16 melanoma cells than that of the mice immunized with injection of B16 cell lysate alone. In conclusion, the cancer vaccine of B16 cell lysates plus poly I:C exerts potently protective effects that polarize responses toward Th1 and elicit antitumor immunity.
