Résumé du contexte et des objectifs généraux du projet

Cell-to-cell communication is a fundamental biological mechanism that allows the adaptation of any organism to environmental changes. Cells sense and respond to environmental cues, such as nutrient availability and stress, via the activation of important signaling molecules, whose activity is crucial to ensure the correct biological responses to constantly changing external demands. Importantly, these mechanisms are often de-regulated in several human diseases, ranging from metabolic disorders to cancer. Despite their relevance, the mechanisms by which cells sense and signal environmental and nutritional inputs is poorly understood. The main goal of this project is to get a deeper molecular understanding on these processes and on their relevance to disease.

Travail effectué depuis le début du projet jusqu’à la fin de la période considérée dans le rapport et principaux résultats atteints jusqu’à présent

Cell-to-cell communication represents an essential process for the coordination of cell functions and the environmental adaptation of multicellular organisms. Primary mediators of such communication are represented by small cellular vesicles released by most cell types known as exosomes.
This project has extended our knowledge on the molecular mechanisms controlling exosome biogenesis and secretion. Furthermore, this project has provided new important data identifying the mechanism by which cells sense and signal nutrient availability in physiological and pathological conditions.

Progrès au-delà de l’état des connaissances et impact potentiel prévu (y compris l’impact socio-économique et les conséquences sociétales plus larges du projet jusqu’à présent)

De-regulation of the mechanisms responsible for nutrient sensing and cell-to-cell communication has been associated to multiple human diseases, including metabolic disorders and cancer. The data generated in this project have profoundly advanced our understanding on the cellular events that modulate such processes. This will have a major impact on both basic and translational science, as it identifies key therapeutic targets for metabolic disease conditions.
