VEGF /VEGFRs signaling plays a pivotal role in the tumor angiogenesis and the development of the immunosuppressive tumor microenvironment in glioblastomas by inhibiting the maturation of dendritic cells (DCs) and stimulating the proliferation of Tregs, TAMs, and myeloid-derived suppressor cells (MDSCs) with VEGFRs expressions [7, 29–32]. This evidence concerns the gene VEGFA and neoplasm.
