suPAR is a biomarker and
therapeutic target for AKI
Catalytic iron is a biomarker
and therapeutic target in AKI
A common genetic variant in HO-1 predicts risk of AKI following cardiac surgery
Immune checkpoint inhibitors cause AKI through tubulo-interstitial nephritis
FGF23 is an early marker of AKI
and death after cardiac surgery
and in critically ill patients
The Leaf Lab conducts patient-oriented research in acute kidney injury (AKI) and critical illness. Our goal is to develop novel approaches to prevent AKI, and to improve outcomes in patients who suffer from AKI. Read more about AKI.
Our research is highly collaborative and interdisciplinary and includes:
• Randomized trials
• Biomarker studies
