Early Effects of Low Dose C Ion or X-Ray Irradiation on Peripheral Blood Lymphocytes of Patients with Alimentary Tract Cancer
The aim of this study was to examine the early effects of low dose 12 C 6+ irradiation or X-ray on peripheral blood lymphocytes (PBL) of patients with alimentary tract cancer and to explore mechanisms that may be involved in an antitumor immune response. We found that the percentage of T lymphocyte...

We found that the percentage of T lymphocyte subsets, the mRNA expression levels of IL-2 and IFN-γ in PBL, and their protein levels in supernatant were significantly increased 24 hours after exposure to low dose radiation.
