Reinvigorating exhausted T cells in cancer and chronic viral infections cells. However, in chronic viral infection and cancer, the killer cells often lapse into “exhausted” CD8+ T cells that no longer can stem disease

Researchers at University of Alabama at Birmingham identify Gfi1 as a crucial regulator of exhausted CD8+ T cell subsets. Fine-tuning Gfi1 activity may prevent or reverse T cell exhaustion, bolstering immune checkpoint blockade therapy. The study suggests potential for improving cancer treatment and controlling chronic infections.
