Institut National de la Santé et de la Recherche Médicale ()
The French National Institute of Health and Medical Research (INSERM) is a public scientific and technological institute and the only French public research institute to focus entirely on human health. Since 2008 INSERM has the responsibility for the strategic, scientific and operational coordination of biomedical research thanks to the scientific quality of its teams and its ability to conduct translational research, from the laboratory to the patient’s bed. INSERM has 318 research units that are set up in university hospitals, cancer research centres and other entities such as Pasteur and Curie Institutes. The UMR_S 1134 unit “Integrated Biology of the Red Cell” is located at the National Institute of Blood Transfusion (INTS) in Paris. Work conducted in this unit focuses on red blood cell biology in normal and pathological conditions. The unit has a long history and strong expertise in red cell membrane proteins exhibiting blood group antigens and filling adhesion, transport or structural function. Presently the UMR_S 1134 established an extended network of physicians in the field of red cell and haematological disorders such as sickle cell disease, myeloproliferative neoplasms, hereditary spherocytosis, Gaucher disease.
