abstract：:Nerve growth factor (NGF) synthesis in cultured mouse L-M fibroblast and astroglial cells can be increased after the treatment with L-threo-3,4-dihydroxyphenylserine (DOPS). Since the increase of NGF is not blocked by the treatment with decarboxylase inhibitor, DOPS may have direct effect to increase the NGF content. ...
