When Neutrophils Do Not Die: Senescence as a New Axis of Tumor Immunosuppression.

Neutrophil senescence driven by glucose deprivation promotes tumor growth by suppressing immune responses in colorectal cancer liver metastases.

• Why it matters: Understanding how neutrophils contribute to tumor immunosuppression can reveal new targets for cancer therapy, especially in the tumor microenvironment where immune evasion occurs.
• What they did: Chen and colleagues used single-cell RNA sequencing to analyze neutrophils in metastatic colorectal cancer, identifying a senescent TAN1 population induced by glucose deprivation that supports tumor progression.
• The result: The findings suggest that targeting neutrophil senescence or metabolic pathways could enhance immune infiltration and inhibit tumor growth, offering potential new strategies for cancer treatment.
