TEAM J. SCHANSTRA/J. KLEIN

CHRONIC KIDNEY DISEASE

Chronic kidney disease has remained a rather “silent” epidemic but recent data have shown that its prevalence has now exceeded 10% of the general population with wide socioeconomic-impact. Our team therefore focusses on early detection, understanding and discovery of molecules that potentially will be able to slow down kidney disease progression and its cardiovascular complications.

CAKUT: Anomalies of the kidney and the urinary tract

 

Coordinators: Bénédicte Buffin-Meyer, Stéphane Decramer, Jean-Sébastien Saulnier-Blache

Congenital anomalies of the kidney and urinary tract (CAKUT) are rare developmental diseases. Although rare, they are the first cause of end-stage kidney disease in children. We develop tools to detect at an early-stage (often in-utero) patients with a high risk of developing severe disease using body fluid omics analysis and aim to better understand the role of specific proteins in the development of CAKUT.

Acute kidney injury

 

Coordinators: Julie Bellière, Stanislas Faguer

Acute kidney injury (AKI) leads to 1.7 million deaths every year worldwide. Compared to other kidney diseases, AKI is is a highly dynamic disease based on a subtle interplay between the epithelial, vascular and immune cells recruited from the circulation in the injured kidney. We aim to study this interplay to generate multiple anchors for detection and intervention.

Cardiovascular complications in chronic kidney disease

 

Coordinator: Julie Klein

Cardiovascular complications are the major causes of mortality in patients with chronic kidney disease. This is mostly due to vascular calcification. Using body fluid omics analysis, we aim to detect at an early stage those patients at high risk of developing such complications and develop novel pharmacological interventions.

So-EcoHealth

 

Coordinator: Colette Denis

Succinate DeHydrogenase Inhibitors (SDHI), are a family of fungicides increasingly used in agriculture. As mitochondrial dysfunction is recognized as an initiator and contributor to a number of renal diseases, we investigate the impact of SDHI exposure in acute kidney injury and progression towards chronic kidney disease. This project is part of the Holimitox network.
