Whole body Irradiation (0.05 GY) was found to increase the levels of DC-related cytokines (IL-2, IL-12, and IFN-γ), promoting biomolecules structural modification [71], triggering anti-tumor immunological responses such as scavenging reactive chemical intermediates, promoting DNA damage repair, reducing inflammation, inducing selective cell apoptosis or senescence, and upregulating both the innate and adaptive arms of the anticancer immune system, allowing the transfer of naive helper T cells to Th1 cells [72–75]. This evidence concerns the gene IL2 and neoplasm.
