    Infiltration of CD163-positive macrophages in glioma tissues after treatment with anti-PD-L1 antibody and role of PI3Kγ inhibitor as a combination therapy with anti-PD-L1 antibody in in vivo model using temozolomide-resistant murine glioma-initiating cells

    Although chemoimmunotherapy often lengthens glioblastoma (GBM) survival, early relapses remain problematic as immunosuppressive M2 macrophages (Mϕ) that function via inhibitory cytokine and PD-L1 production ca...
