The purpose of this study was to further elucidate the radioprotective role of granulocyte colony-stimulating factor (G-CSF) induced in response to irradiation. The induction of G-CSF and interleukin-6 (IL-6) in response to radiation exposure was evaluated in mice. The level of cytokine in serum was determined by multiplex Luminex. The role of G-CSF on survival and tissue injury after total body gamma-irradiation was evaluated by administration of neutralizing antibody to G-CSF before radiation exposure. An isotype control was used for comparison and survival was monitored for 30 d after irradiation. Jejunum samples were used for immunohistochemistry. Ionizing radiation exposure induced significant levels of the hematopoietic cytokines G-CSF and IL-6, in mice receiving 9.2 Gy radiation. Maximal levels of G-CSF were observed in peripheral blood of mice 8h after irradiation. IL-6 levels were maximum at 12h after irradiation. Administration of G-CSF antibody significantly enhanced mortality in irradiated mice. G-CSF antibody-treated mice had higher numbers of CD68(+) cells and apoptotic cells in intestinal villi. Our results confirm that radiation exposure induces elevations of circulating G-CSF and IL-6. Neutralizing antibody to G-CSF exacerbates the deleterious effects of radiation, indicating that G-CSF induced in response to irradiation plays an important role in recovery.
