To test whether the modified chemokine production patterns in BCG- and IFNα + poly-I:C-treated bladder cancer tissues result in their differential ability to attract CTLs, supernatants of the differentially-treated bladder cancer tissues were tested for their ability to attract ex vivo-induced effector CD8+ T cells (pre-activated by SEB-loaded LPS + IFNγ matured DCs, capable of high IL-12 production [36,37]). This evidence concerns the gene IFNG and urinary bladder carcinoma.
