Co-injection of both GM-CSF-secreting cells with Poly(I:C) led to improved tumor control and survival compared to mice receiving only PBS injections, with 4/10 mice receiving 3T3/GM-CSF cells and 5/10 mice receiving Neuro-2a/GM-CSF cells in conjunction with Poly(I:C) showing complete tumor regression and maintaining long-term survival (Figure 1A,B, p < 0.001). The gene discussed is CSF2; the disease is neoplasm.
