Immunizations with unmodified tumor cells and simultaneous COX-2 inhibition eradicate malignant rat brain tumors and induce a long-lasting CD8(+) T cell memory.
Malignant brain tumors induce pronounced immunosuppression, which diminishes immune responses generated by immunotherapy. Here we report that peripheral immunotherapy, using irradiated unmodified whole tumor cells, and systemic cyclooxygenase-2 inhibition induce cure in glioma-bearing rats (60% cure rate), whereas neither monotherapy was sufficient to cure any animal. Moreover, the combined therap
