The scientific projects of the team are developed handin-hand with national and international bodies (in particular with the Cancéropôle Grand Sud-Ouest (Greater South-West Cancer Centre and European networks). The team implements cutting-edge molecular and cell biology methods (in particular transgenesis and homologous recombination) for three types of research objectives :

Fundamental : molecular mechanisms that regulate antibody production / study of genetic remodeling associated with the differentiation and maturation of immunity cells and more particularly B lymphocyte / biology of B lymphomagenesis B and tumour transformation /physiology of the normal B lymphocyte, etc.

In relation to experimental medicine issues : development of mechanistic models for studying immunopathological or onco-hematological disorders / participation in clinical research / involvement with the National Reference Centre on amyloidosis and immunoglobulin deposition diseases / implementation of new diagnostic tools for lymphomas;

Finalized : approaches that are specifically related to improving the diagnosis and treatment of tumoral (in particular hematological) and dysimmune pathologies / technological developments that focus on flow cytometry methods. This array of theme variations, which focuses mainly on the B lymphocyte, provides mutual benefit in the different research areas. Studying pathological mechanisms and possible therapeutic applications simultaneously promotes fundamental research and can occasionally guide it. The location within the medical cluster privileges interactions and complementarity between fundamental and clinical research.
