NFKB1 and neuroblastoma: Downstream correction of the stoichiometric insufficiency of IRF1 and NF-kB restores the presentation of tumor antigens in a model NB cell line, providing the proof of principle that complex immune escape phenotypes can be rescued by a limited number of master genes, and that NB can be made sensitive to CTLs that otherwise would be unable to recognize expressed, endogenous NB tumor antigens.
