Research themes

Our project aims at investigating the cellular and molecular mechanisms that regulate autophagic pathway during stress response in cooperation with other endomembranes, in physiological and pathophysiological situations.
We study intracellular signaling and trafficking pathways (golden lines, figure below) that connect the autophagosome with endomembranes (primary cilium, mitochondria, endosomes, ER, etc.), or infectious agents, during integration of nutritional and mechanical stresses.
