Research Projects

On the ground of our interests for molecular piracy exerted by tumor cells to survive, adapt and remodel their environment, we explore the signaling mechanisms involved in non-oncogene addiction and loss of vascular homeostasis.
Our research program is organized around four main axis:
1. Cell-Cell Interactions.
2. Intracellular Signaling and Post-Translational Modifications.
3. Extracellular Communication and Vesicles.
