Basic & Clinical Research

We use an integrative physiological approach to learn more about the central role that the kidneys play in the homeostatic regulation of body fluid composition. The research of Kidney.CH is organized in 3 work packages, each of which focuses on a kidney centred homeostatic theme.

    Mineralisation in kidney disease

    The tubular segments of the kidney play essential roles in the handling of specific solutes that either promote (e.g. Ca2+, Pi, oxalate) or inhibit (e.g. Mg2+, citrate, uromodulin) the formation of crystals in the lumen of the nephron, which may lead to kidney stones, kidney injury, inflammation, and eventually result in the evolution of chronic kidney disease (CKD). The main objective of this WP is to establish biochemical and/or genetic risk profiles and to identify potential targets to prevent or slow the development of CKD associated with crystallization disorders.

    Uromodulin: from physiology to kidney disorders

    Olivier Devuyst

    This project focus on the following scientific questions:

    1. What are the physiological regulators of uromodulin production and what are the roles of the uromodulin matrix inside the lumen of kidney tubules?
    2. By which mechanisms UMOD mutations cause tubulointerstitial kidney disease and what is the role of ER/oxidative stress, unfolded protein response (UPR) and autophagy in the progression of CKD?
    3. What is the role of UMOD promoter variants and uromodulin in complex disorders including CKD and kidney stones?

    Phosphate transporters in renal disease

    Carsten Wagner

    Renal phosphate (Pi) transport is mediated by several Pi transporters that when mutated in humans cause hypophosphatemia, hypercalciuria and kidney stones. Genetic variants in the two main Pi transporters, SLC34A1 and SLC34A3, are common. We examine the clinical and functional relevance of these variants for kidney stone disease and chronic kidney disease.

    Magnesium & CKD

    Uyen Huynh-Do

    In this project a well characterized kidney transplant cohort is studied for a longitudinal analysis of the prevalence, determinants and impact of hypomagnesaemia on surrogate markers and hard endpoints of CKD and chronic venous disease (CVD) progression. The human studies are complemented by mechanistic studies in a mouse model of accelerated calcification and with development of end stage renal disease.
