Disease-associated microglia adopt stage-specific phenotypes that regulate T cell fate and immunity in glioma
Immunity Published 2026-07-24 Research Article DOI: 10.1016/j.immuni.2026.06.024
microglia glioma T cell tumor microenvironment immunity brain tumor
Summary: Characterizes how disease-associated microglia (DAMs) in glioma are not fixed suppressors but evolve with tumor stage. DAMs transition from antigen-presenting and checkpoint-regulatory states to T cell-clearing programs, shaping local T cell responses in the brain. Early-stage microglia promote T cell recruitment and activation, while late-stage microglia adopt immunosuppressive phenotypes that promote T cell exhaustion and exclusion. Identifies molecular drivers of this phenotypic switch and demonstrates that targeting the microglial transition point restores anti-tumor immunity in preclinical models.
Why it matters: Microglia are the most abundant immune cells in the brain tumor microenvironment, yet their role in regulating T cell immunity has been poorly understood. This study reveals that microglia are not passive bystanders but active, stage-dependent regulators of T cell fate — a finding with direct implications for immunotherapeutic strategies in glioblastoma.
Why for Yiru: Microglia-T cell crosstalk in the glioma TME is highly relevant to your interests in tumor-infiltrating immune cells and immunotherapy resistance mechanisms.

pancreatic cancer quiescent tumor cells immunosuppression EREG CAR-T tumor microenvironment
Summary: Using orthotopic PDAC mouse models, identifies a rare population of quiescent PDAC cells that increases after CAR-T cell therapy and exhibits relatively higher clonogenic growth and self-renewal potential than bulk tumor cells. These quiescent cells express high levels of Epiregulin (EREG), a secreted ligand for EGFR and ErbB4, and induce an immunosuppressive microenvironment that limits CAR-T efficacy. Targeting EREG signaling sensitizes PDAC to CAR-T therapy.
Why it matters: Immunotherapy has limited activity in pancreatic ductal adenocarcinoma. This study identifies quiescent tumor cells as key drivers of immunosuppression and CAR-T resistance in PDAC, providing a mechanistic understanding of therapy failure and a potential strategy to overcome it by targeting EREG signaling.
Why for Yiru: The connection between tumor cell quiescence and immunosuppression in PDAC is directly relevant to your interests in tumor microenvironment interactions and immunotherapy resistance. The EREG-EGFR axis provides a potential therapeutic target for combining with cellular therapies.
