We have reported before that treatment of tumor bearing mice with a combination of the anti-cancer chemotherapy cyclophosphamide (CTX) and immunotherapy can result in complete tumor regression using T-cell receptor (TCR) transgenic CD8\n                    <jats:sup>+<\/jats:sup>\n                    T cells specific to antigens. This study aimed to determine whether chemotherapy can cure immunogenic tumor which expresses non-self-tumor antigen and result in antitumor immunity. Either EL4 cell line, a poorly immunogenic thymoma, or EG7, a clone of EL4 cells transfected with ovalbumin (OVA), as a non-self-antigen were inoculated subcutaneously into wild type or splenectomized C57BL\/6 mice and then treated once with intraperitoneal (i.p.) injection of 4\u2009mg CTX\/mouse. In certain experiments, the mice were rechallenged with the same tumor type 1\u20132\u2009months after the primary challenge. Treatment of EL4 bearing mice with CTX induced transient antitumor effect followed by tumor progression. Interestingly, however, treatment of EG7-bearing mice with CTX resulted in regression of early and advanced tumors. EG7 tumor-free mice rejected the second and the third challenges with EG7 cells, but not with challenge EL4 cells. These antitumor effects did not require spleen, since splenectomized mice showed similar antitumor effects of CTX on EG7 cells. Taken together, these data indicate that expression of non-self-antigen by poorly immunogenic tumor might be a reliable means to increase its immunogenicity and its response to chemotherapy.\n
