Breakthrough Reprograms Exhausted T Cells to Fight Tumors

2/11/2026

Summary

Story summary

Researchers at the Salk Institute for Biological Studies and other institutions developed a framework to reprogram exhausted CD8 T cells.
They identify transcription factors ZSCAN20 and JDP2 as key regulators of T cell performance.
By turning off these factors, they restored exhausted T cells’ tumor-killing function while preserving long-term immune memory.
The work challenges the view that immune exhaustion is inevitable and could improve therapies for solid tumors.
