IL10 and glioblastoma: In a parallel study with the GL261 GBM model (Supplementary Fig. 6a), triple treatment similarly decreased the populations of IL-10+F4/80+ Mφs (Supplementary Fig. 6b), enhanced the infiltration of CD45+CD8+ T cells into the tumors (Supplementary Fig. 6c), and increased the populations of CD45+CD8+IFN-γ+ active T cells (Supplementary Fig. 6d).
