A word from the director

Dr. Michael Schumacher, DR1 INSERM

Our laboratory « Diseases and Hormones of the Nervous System » addresses unmet medical needs related to diseases and lesions of the central and peripheral nervous systems: protecting neural cells, promoting regeneration, including the regeneration of myelin, and improving functional recovery.

January 31, 2024. Male hormones protect against myelin loss by modulating astrocytic chemokines

Multiple sclerosis affects three women for every man. Male hormones including testosterone promote the synthesis of myelin and limit the signs of the disease. Faced with this observation, the research group led by Abdel Ghoumari showed that testosterone and the chemokine receptor CXCR4 involving astrocytes is necessary for myelin regeneration. These results highlight, for the first time, a mechanism of action of pro-myelinating androgens, via chemokine signaling for the combined therapy of myelin pathologies.
