Brief Summary: This study investigated the synthesis pathway of pregnenolone (PREG) in the central nervous system. It identified the P450 enzyme CYP1B1 to be responsible for the production of PREG in human glial cells.Comment: Steroids have important functions in the central and peripheral nervous systems, including modulation of behavior, pain, stress and inflammation.
