Cultured astrocytes contain immunologically specific aromatic L-amino
acid decarboxylase (AADC) protein and express the AADC gene. Following
incubation with L-Dopa, glial cultures synthesize and metabolize dopa
mine. The addition of pyridoxal 5-phosphate did not change the rate of
dopamine synthesis. The formation of dopamine was blocked by NSD-1015
. These experiments show that mouse cultured astrocytes are capable to
convert L-Dopa into dopamine in a dose-dependent fashion.
