Cytokine induction following ionizing radiation exposure occurs through transcriptional activation in specific proteins studied to date. This process can be blocked by inhibition of radiation-induced signaling pathways, which may potentially modify certain deleterious effects of radiotherapy, e.g., effects related to production of TNF or TGF-beta. bFGF is another radiation-inducible protein that may participate in repair and protection of irradiated endothelial cells following a complex interaction with cellular receptors. The cytokines such as IL-6, TNF, and IL-1 may be useful to protect hematopoietic cells from radiation, while TNF may enhance the killing of tumor cells. Our understanding of cytokine/radiation interactions is only beginning to be understood, but knowledge of the biology of these interactions may prove clinically useful.
