ELF4 is a conserved, immune-enriched transcription factor in human kidney disease, linked to severity and expressed highest in NK cells.
- Why it matters: Chronic kidney injury often ends in fibrosis, but conserved immune regulators that translate across species and connect immune state to disease progression are unclear.
- What they did: The study integrated human kidney transcriptomes with multiple murine kidney fibrosis models, then used Elf4 deletion (including NK-specific ablation), single-cell profiling, and functional assays to test NK maturation and effector programs.
- The result: Elf4 loss attenuated experimental kidney injury, reducing inflammation and fibrosis and impairing late NK maturation; it broadly suppressed cytotoxic and IFN-γ programs by directly sustaining STAT1 and the STAT1–TBX21 program, and NK depletion, IFN-γ neutralization, or antisense Elf4 suppression phenocopied protection.
