Incubation of striatal synaptosomes under depolarizing conditions (veratridine or KCl) increased the release of dopamine (DA) and produced a small increase in DA synthesis. This was not accompanied by an activation of either soluble or membrane-bound tyrosine hydroxylase, but was associated with a large depletion of synaptosomal DA. Thus, depolarization may increase DA synthesis by reducing the inhibition of tyrosine hydroxylase by end-product.
在去极化条件下（藜芦碱或氯化钾）孵育纹状体突触体，可增加多巴胺（DA）的释放，并使DA合成略有增加。这并未伴随可溶性或膜结合型酪氨酸羟化酶的激活，但与突触体DA的大量消耗有关。因此，去极化可能通过减少终产物对酪氨酸羟化酶的抑制来增加DA合成。
