    Abstract

    Myeloid Antigen-Presenting Cell Niches Sustain Antitumor T Cells and License PD-1 Blockade via CD28 Costimulation

    Investigators showed that tumor-specific CD8+ tumor-infiltrating lymphocytes accumulated in tumor islets, where they engage antigen and upregulate PD-1, which restrained their functions.

    Abstract

    Multispecific Targeting of Glioblastoma with Tumor Microenvironment-Responsive Multifunctional Engineered NK Cells

    Scientists describe a unique, sophisticated combinatorial platform for glioblastoma (GMB): a cooperative multifunctional immunotherapy based on genetically engineered human NK cells bearing multiple antitumor functions including local tumor responsiveness that addresses key drivers of GBM resistance to therapy

    Abstract

    Phagocytic Uptake of Polymeric Particles by Immune Cells under Flow Conditions

    Investigators used an in vitro peristaltic pump setup that mimiced pulsatile blood flow to determine if immune cells took up particles under constant fluidic flow.

    Pharmacological Inhibition of BACE1 Suppresses Glioblastoma Growth by Stimulating Macrophage Phagocytosis of Tumor Cells

    By screening a collection of small-molecule compounds, investigators found that inhibiting β-site amyloid precursor protein-cleaving enzyme 1 (BACE1) with MK-8931 potently reprogrammed tumor-promoting macrophages into tumor-suppressive macrophages and promotes macrophage phagocytosis of glioma cells.
