Innate Lymphoid Cells in Septic Shock

The investigators will take two kits of blood samples for the group 1, one during the early stage of the septic shock (48 first hours of care) and one during the late stage of the disease (between the fourth and the sixth day). We'll take only one kit of blood samples for the group 2. One kit includes one EDTA tube (5 mL) and five Lithium Heparin tubes (25 mL). The immune mapping will be made by Julien Carvelli, a gold medalist resident, in the framework of a Master 2. The analyses will be made in the laboratory of immunology in the Conception Hospital (Pr Vivier's team).
