Research themes

Our research team is integrated in the Mediterranean Center for Molecular Medicine (C3M) in Nice, formerly Inserm U1065. Our work focuses on the genesis, differentiation, and transformation of hematopoietic stem cells with a special emphasis on myeloid cells. Our current research project is articulated around 3 main axes: The first one concerns the role of oxydative stress in the maintenance, the proliferation and engraftment of hematopoietic stem cells. The second one studies the role of caspases and autophagy during monocyte differentiation into macrophages and their subsequent polarization. Finally, our last research axe analyses the involvement of lysosomes and different forms of autophagy in the regulation of myeloid leukemia and the development of MDS into AML.

Descriptive figure

Figure 1: NB4 cells are stimulated with All-trans Retinoic Acid (ATRA) for 24h. These cells are then lysed in a nitrogen disintegration bomb and the organelles from these cells are purified by ultracentrifugation on sucrose gradient. The recovered fractions are analyzed by western blot to determine the modifications linked to the ATRA treatment. The antibodies shown (right panel) are purity controls for the different organelles.
