Cell Biology

The program offers a refresher course and an in-depth study of the major concepts and methodologies of cell biology, organized around different themes:

1 Cytoskeleton:Introduction to the different types of cytoskeleton. Polymerization properties of actin and tubulin. Proteins associated with the cytoskeleton and regulating polymerization. Molecular motors. Principles of cell migration.

2.cell adhesion & signaling: cell-cell and cell-extracellular matrix adhesive structures, their molecular organization and dynamics. Functions and regulation during development and pathogenesis. Regulation by signaling pathways. Mechanotransduction.

3 Addressing and cell trafficking: Ubiquitination and proteasome. Addressing to subcellular compartments, endocytosis and secretion pathways. Molecular basis of vesicular transport, budding, fusion, molecular motors. Signaling in membrane trafficking, trafficking-related genetic diseases and pathogen detour.

4 Cell cycle: Historical introduction. Molecular regulation of the cell cycle. The mitotic spindle, microtubule dynamics and molecular motors, chromosome attachment mechanisms, checkpoints, regulation of mitosis exit and cytokinesis. Mitotic disorders associated with cancer cells.

5 Stem cells: cell differentiation, toti-, pluri- and multipotency, embryonic, adult and cancer stem cells.

6 Programmed cell death: Apoptosis, autophagy, necrosis. Stages and modalities of apoptosis, signaling pathways involved. Role in maintaining homeostasis. Pathophysiological consequences of deregulation of programmed cell death.

Different study models are presented, to introduce the importance of the contribution of biological diversity to the discovery of cellular and molecular mechanisms, and to the understanding of human pathologies.
