Team 3 leaders: Pr. Gilles Blancho & Dr. Sophie Limou
 

Research program

Team 3 results from the merging of two teams previously working in the field of transplantation and immunotherapy on the one hand and in the field of translational immunogenetics on the other hand. Our new Team 3 will develop complementary and integrative "wet-lab" and "dry-lab" strategies to improve the understanding of these complex pathophysiological mechanisms. Our main objectives are 1) to identify immunologic, genetic and HLA/immunogenetic determinants of kidney allotransplantation failure and of other immune-mediated kidney diseases, 2) to characterize the immunological role of unclassified human cell surface proteins and to define their potential as new targets for immunotherapies and 3) to integrate these findings in personalized clinical decision processes.

Our team has a history of clinical data development (genomic and digital applications) and of translational research from bench to bedside (e.g. FR104 immunotherapy, OneStudy). We also lead local technological platforms that support our projects: Our research program is divided into two main axes:

1. Transplantation, immunogenomics and immunotherapies

We develop immunogenomic strategies for kidney transplantation in order to better define HLA and non-HLA incompatibilities between donor and recipient and to characterize the determinants of chronic graft rejection, such as HLA and non-HLA donor specific antibodies (DSA). Using animal models, we aim at pre-conditioning kidney grafts before transplantation to protect them against HLA DSA and other immune aggressions through various strategies, including accommodation. In addition, we study immune functions of uncharacterized human cell surface proteins (surfaceome), such as CD28H and SIRPgamma, in order to define their immunotherapeutic potential. Finally, data integration and machine learning will allow us to develop clinical scores and a personalized medecine application to guide the follow-up of transplanted patients.

2. Nephrogenomics, integrative functional immunogenetics and immune-related kidney injuries

Our ambition is to promote in silico functional immunogenomics by statistically inferring knowledge from SNPs to better understand the immune mechanisms underlying kidney injury. In addition, we are working to better characterize the factors regulating trafficking of extracellular vesicles carrying miRNAs that damage the vascular endothelium during inflammation in ANCA-associated vasculitis (AAV), in order to investigate therapeutic strategies. Finally, we have recently started to develop nephrogenomics as a strategy to support diagnosis and discovery of new therapeutic targets for kidney injury (e.g. phosphate diabetes...)
