Link Between the Peripheral Mononuclear Cells' Capacity to Induce Insulin Resistance and Hyperinsulinemia

This is a two-center proof-of-concept study, ancillary to the MetACTIV study, whose objective is to define immune activation profiles from the data of individuals followed by the Caisse Primaire d'Assurance Maladie du Gard (health insurance fund). The IRACTIV study will include a subset of volunteers from the MetACTIV study for whom a blood sample will be taken as part of the IRACTIV study.
