1 Fig. 5 Combination intravenous reovirus and checkpoint inhibition in an orthotopic syngeneic brain tumor model. Combination intravenous reovirus and checkpoint inhibition in an orthotopic syngeneic brain tumor model. C57/BL6 reovirus-vaccinated mice (22) were injected with GL261 cells intracranially on day 1 and treated using combinations of granulocyte-macrophage colony-stimulating factor (GM-CSF) plus intravenous reovirus and/or anti–PD-1 antibody. (A) Kaplan-Meier survival plot, with Mantel-Cox comparison of survival curves: control versus anti–PD-1 (P = ), control versus GM-CSF/reovirus (P = ), control versus GM-CSF/reovirus + anti–PD-1 (P < ), GM-CSF/reovirus versus GM-CSF/reovirus + anti–PD-1 (P < ), and anti–PD-1 versus GM-CSF/reovirus + anti–PD-1 (P < ). (B) Representative brain tumor hematoxylin and eosin–stained sections from PBS-treated and GM-CSF/reovirus-treated mice. Black arrows mark vascular endothelial cells; white arrows mark lymphocytes. Scale bars, 30 μm. (C) Flow cytometry quantification of CD3+ CD4+ IFN-γ+ or CD3+ CD8+ IFN-γ+ TILs from PBS-treated or GM-CSF/reovirus-treated mice. Graph shows the mean ± SD of four samples.
