From a biological viewpoint, the function-centred approach recommended by WHO represents a challenge due to the multidimensionality that characterizes intrinsic capacities’ trajectories during aging.
Therefore, to better appraise the functional construct, INSPIRE will develop an integrative view of biological aging. Three classes of parameters transversal to the whole organism, present in all organs and strongly interrelated are crucial in this tissue homeostasis: inflammation and immunity that represents both a warning signals and the house keeping guard of tissue integrity, mesenchymal stem/stroma cells (MSC) allowing support for all function and their adaptation and metabolism that controls any cell decision and the fate of most of them. In top of that senescence both at the level of the cell or the whole organism is a common mechanism involved in many aspect of aging.
The scientific projects resulting from these general objectives are based either on a priori approaches resulting from results already obtained by the partner laboratories; or on non-supervised approaches involving strong collaborations between research centers with complementary skills.
These projects will be based on the various INSPIRE cohorts (human and animals), some examples are given thereafter.
