Synaptic like microvesicles: do they participate in regulated exocytosis?

abstract：:The present study was designed to investigate the turnover rates of D1 dopamine receptors in the brain and retina of adult and aged rats. To this aim, we monitored the increase in the density of 3H-SCH 23390 binding sites after the administration of the irreversible antagonist N-ethoxycarbonyl-2-ethoxy-1,2 dihydroquin...
