Non-tumor-bearing and Ad5E1 clone 2.1 tumor-bearing eyes of C57BL/6, IFN-γ KO and SCID mice were harvested. RNA was isolated and converted to cDNA. mRNA expression of IL-17 (A), IL-6 (B), CD8 (C) and perforin (D) was determined by qPCR. Samples were normalized to GAPDH and compared to IL-6 KO eye. As positive controls for IL-17 and IL-6, Th17-polarized CD4+ T cells and RAW 264.6 cells polarized into a Th17 or M1 phenotype, respectively. Data are a representative of two independent experiments. TB, tumor-bearing; n.d., not detected.
