| Type | MGI:General | Description | evoked catecholamine secretions from chromaffin cell are decreased 33% compared to in wild-type mice exocytosis spikes are less than in wild-type cells L-DOPA-treated cells fail to uptake more catecholamines unlike similarly treated wild-type cells chromaffin cells exhibit a reduction in catecholamine secretion per quantal size of exocytosis compared with wild-type cells |
