Scientific summary

Dynamic videonanoscopy of immunocancer interactions

Cell junctions play a key role in the integrity of biological tissues through interactions between cell surface proteins. These interactions are profoundly altered during the development of cancerous cells as well as during the passage of leukocytes through the walls of blood vessels, in infectious or tumour contexts. Advances in optical microscopy make it possible to detect a single fluorescent molecule with nanometric precision. This approach provides a resolution comparable to electron microscopy, while being compatible with the observation of living cells.

My goal is to document the dynamics of adhesion molecules by videonanoscopy. The analysis of molecular trajectories using dedicated personal algorithms will allow the identification of interaction, stabilization and intracellular trafficking events. The establishment and dynamic evolution of junctions will be studied in different cellular, immune and cancerous contexts.
