Pathophysiology of glomerular diseases

Research topic

Our work is devoted to the study of human glomerular diseases, the leading causes of renal failure in the world, with two main axes around idiopathic nephrotic syndrome (axis 1) and nephro-oncology (axis 2).

 

In the first axis, the team studies the immunopathological mechanisms of glomerulopathies. Its work has made it possible to identify certain candidate genes for which animal models have been developed or are in progress. Current work aims to functionally characterize some of these models.

 

The team is also exploring the immuno-pathogenic link between environmental stress (infection, pollution) and flare-ups and relapses of idiopathic nephrotic syndrome.

 

The team’s second line of research aims to understand the pathogenic mechanisms underlying glomerulopathies induced by oncology therapies (chemotherapy or targeted biological treatments), at the cellular and molecular level. Indeed, this work involves the study of cell signalling pathways, as well as the study of communication between the different cell types of the glomerulus (podocytes, parietal epithelial cells, endothelial cells).
The team is developing innovative therapeutic approaches based on the treatment of experimental podocytopathies by nano-interference .

 

The team benefits from the coordination of the National Reference Centre for Idiopathic Nephrotic Syndrome and access to its cohorts and biobanks.
