The REGOS team of the Inserm U1229-RMeS laboratory is pleased to announce the recent funding of the OVERbone proposal as an ANR collaborative research project. OVERbone will be coordinated by Valérie Geoffroy and Angélique Galvani (Inserm U1229, RMeS) and will be carried out with Pierre Weiss (Inserm U1229, RMeS) and in collaboration with Patricia Abellan and Jean Le Bideau (IMN, CNRS U6502). OVERbone aims to investigate a novel mechanism of bone formation based on extracellular vesicles (EVs) secreted by bone cells, that could be used as therapy for bone regeneration. In addition, OVERbone will demonstrate that these EVs are altered during aging either in quantity or in quality and that this alteration contributes to bone aging.

Launching of the second transversal Inserm program dedicated to Aging (AGEMED 2.0)

The STEP Team is happy to announce that the second transversal Inserm program dedicated to Aging (AGEMED 2.0) will receive a 1.5 M€ grant for the next three years. This research program, coordinated by Eric Gilson (Nice), gathers 11 Research teams from Paris, 2 from Marseille and Grenoble and 1 from Montpellier and Nantes (RMeS STEP team, J.Guicheux and C. Vinatier). The long-term vision of this Inserm program on aging is to ameliorate age-related disorders, improving overall healthspan and reducing public health costs. AGEMED 2.0 will be organized around two main axis. The first axis aims at deciphering the cell senescence code to improve healthspan in chronic obstructive pulmonary disease, idiopathic pulmonary fibrosis and osteoarthritis. The second axis deals with integrated approaches to prevent and treat neuroaging disorders in various pre-clinical models. RMeS will receive a financial support for three years to test the efficacy of senolytic compounds in several murine models of osteoarthritis.
