Interleukin-15 is a recently discovered cytokine which is functionally similar to IL-2. In order to learn more about possible targets for modulation of the expression of IL-15 we investigated the expression of IL-15 mRNA and protein in the A549 (human lung carcinoma) cell line. Constitutive expression of IL-15 mRNA was detected in A549 cells. Treatment with TNF-alpha or IL-1 beta (10 ng/ml each) induced an about 2-fold increase of IL-15 mRNA; IFN-gamma induced significant effects only at 100 ng/ml. Stimulation with a combination of TNF-alpha and IFN-gamma was not superior to stimulation with TNF-alpha alone. EGF, KGF and the combination thereof were without effects. IL-15 protein was detected in cellular lysates of unstimulated cells and was increased by stimulation with TNF-alpha or IL-1 beta. No significant amounts of IL-15 protein were detected in cellular supernatants.

Molecular targeting is a promising option to increase the radiation response of tumours and to decrease normal tissue reactions, i.e. to achieve therapeutic gain. Molecular targeting substances in themselves are not curative while radiation is a highly efficient cytotoxic agent, with local recurrences often occurring from only few surviving clonogenic cells. High-dose radiotherapy therefore offers optimal conditions to evaluate the potential of specific biology-driven drugs for oncology. This review summarises the current status of preclinical and clinical research on combined radiation with examples of molecular targeting substances relevant for the treatment of NSCLC (EGFR, COX-2, VEGFR, KGF, TGF-beta, BBI).
