Initiated by Jean-François Moreau, this project is based on the idea that mobility is central to immunity. In the transition from unicellularity to multicellularity, all cells have mostly lost their mobility – except for the immune cells. We are interested in better characterizing this link between immunity and mobility, and the way it emerged through evolution. On this ground, we propose a novel hypothesis about aging and immunosenescence, based on the idea that the increasing stiffness and cross-linking of the senescent ECM lead to progressive immunodeficiency via an age-related decrease in T cell mobility and the death of these cells.
