How Tamm‑Horsfall protein helps kidneys recover after sudden injury
The immunomodulatory function of Tamm-Horsfall protein in acute kidney injury
This project looks at whether a kidney protein called Tamm‑Horsfall helps the kidney heal after sudden injury in people with acute kidney injury.

What this research studies
Researchers will use mice that either make or lack Tamm‑Horsfall protein (THP) to see how the protein affects immune cells in the kidney after acute injury. They will track neutrophil entry, the number and activity of healing macrophage‑type cells, and tissue repair over time using imaging and laboratory tests. The work builds on earlier findings that THP influences immune cell behavior and focuses on how THP supports recovery. Results are intended to guide future efforts to develop therapies that alter THP activity to help people recover from acute kidney injury.
Who could benefit from this research
Good fit: People hospitalized with acute kidney injury or those at high risk for AKI (for example after major surgery or severe infection) would be most relevant to future therapies based on this work.
Not a fit: People with long‑standing end‑stage kidney disease on dialysis or chronic kidney conditions unrelated to acute injury are unlikely to benefit directly from these findings.
Why it matters
Potential benefit: If successful, this work could point to new treatments that boost the kidney's natural healing and improve recovery after acute kidney injury.
How similar studies have performed: Previous animal studies by this team showed THP affects neutrophil infiltration and recovery, but using THP‑based approaches as treatments remains an early, mostly preclinical strategy.
