An article published this year inIEEExplore Digital Library using one of our products, Propidium Iodide”, by our customers from Department of Advanced Energy, the University of Tokyo, Kashiwanoha, Kashiwa, Chiba, Japan., in the analysis of how Genotoxicity of tetrahydrofolic acid to hematopoietic stem and progenitor cells. Congrats and Thanks.


Summay:
Plasma irradiation of cancer is expected to activate a cancer-specific immune response; however, its long-term systemic effect in animal models has not been sufficiently investigated. In this study, the long-term systemic effect induced by plasma irradiation was examined using C57BL/6 mice inoculated with B16F10 melanoma. Melanoma tumors on the right hind legs of the mice were resected after treatment with nanosecond pulsed streamer discharge. The results showed that plasma treatment delayed the growth of recurrent tumors at the site of resection. In addition, plasma treatment delayed the growth of tumors re-inoculated at the non-irradiated site on the left leg of the mice after resection. Histological and single-cell analyses revealed that plasma had no direct effect on primary tumors, whereas it enhanced cytotoxic T cell infiltration into re-inoculated tumors. These results suggest that plasma treatment induces cancer-specific long-term immune memory in mice.
