Immunity, mobility, and aging

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.

Immunity and the constant construction and maintenance of biological boundaries

Recent data show that the immune system is not just a system of elimination and defence, but is involved, much more broadly, in development, regulation, and repair. One key problem is to determine how the immune system constantly patrols and repairs biological boundaries, such as the epithelium and the endothelium. We are particularly interested in how innate lymphoid cells (ILCs) and gammadelta T cells are involved in this process. We are developing, with Patrick Blanco’s group, a translational program exploring the role of ILC2s in controlling and maintaining the endothelium, both in physiological and pathological conditions, including in fibrosis and systemic sclerosis.

Understanding immunogenicity

Understanding the triggering of an immune response

The aim of this interdisciplinary project is to offer, through the articulation of conceptual, experimental, and medical perspectives, a better characterization of how the immune system is activated. What triggers an effector or a regulatory immune response? How can concepts, theories, and models help us understand how the immune system is activated? One aspect of this investigation is the assessment of the “discontinuity theory” Pradeu, Jaeger and Vivier 2013; Pradeu and Vivier 2016), which states that effector immune responses are triggered by sudden changes in the molecular patterns with which immune receptors interact.
