ABSTRACT
Background:
Nanosecond pulsed electric fields (nsPEFs) showed an inhibitory effect on proliferation of malignant melanoma. In this study, the growth of melanoma were inhibited by changing the systemic immunity. Material andMethods:
C57BL/6 mice with B16 malignant were exposed to 200 pulses of 100 ns duration, 30kV/cm. The mice were executed four days later. T lymphocyte has been extracted from spleen. Cell viability was evaluated by CCK-8 assay. CD3+CD4+T cells, CD3+CD8+T cells, regulatory T cells (Treg) and myeloid-derived suppressor cells (MDSC) were analyzed by flow cytometry. TNF-alfa, IL-2, IL-10, TGF-β, IFN-γ levels in supernatants were assessed by ELISA.Results:
C57 malignant melanoma model were established successfully. After the treatment of nsPEFs (30 kV/cm 100 ns 200p), the numbers of T lymphocytes were increased. CD3+CD4+T cells changed from 48% to 51.2%; CD3+CD8+T lymphocytes increased from 39.6% to 40.4%. Treg cells reduced from 4.3% to 2.4%, MDSC decreased by 39.0% to 19.7%. In addition, the level of TNF-α, IL-2 were increased (P < 0.05) and the level of IL-10 were decreased (P < 0.05) and the level of TGF-β and IFN-γ remained stable (P > 0.05).Conclusions:
Tumor growth can be effectively inhibited by nsPEFs in vivo, which activate targets of immune respones, accumulation of inflammatory cells and immune cytokinesRESUMEN
