Elucidating the molecular basis of cell polarity and mechanisms of intracellular trafficking are fundamental goals in cell biology, not only for the understanding of basic cell function but also because alteration of these processes underlies many diseases. The work in our lab is focused on the study of the molecular mechanisms regulating protein sorting and intracellular trafficking in polarized epithelial cells and neuronal cells, and on the mechanisms of protein(s) and organelle(s) exchanges between cells, with the aim of understanding how these pathways contribute to/are altered in diseases like cancer and neurodegenerative disorders.
To unravel these questions we have applied different approaches including molecular biology, protein/lipid biochemistry, biophysics, mathematical modeling, quantitative high resolution and live imagingin four projects listed below:
