Resumen del contexto y de los objetivos generales del proyecto

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.

Trabajo realizado desde el comienzo del proyecto hasta el final del período abarcado por el informe y los principales resultados hasta la fecha

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.

Avances que van más allá del estado de la técnica e impacto potencial esperado (incluida la repercusión socioeconómica y las implicaciones sociales más amplias del proyecto hasta la fecha)

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.
