Dopamine organic cation transport

The existence of a carrier-mediated transport in nasal mucosa was first suggested by Kimura et al. [34], P-glycoprotein, organic cation transporter, dopamine transporter, and amino acid transporters have all been identified in the nasal mucosa, especially in the olfactory mucosa [31, 32, 35, 36], These transporters determine the polarized absorption and excretion of their substrates including amino acids, amines, and cations. 

ABBREVIATIONS NET, norepinephrine transporter, originally known as uptake 1 DAT, dopamine transporter ENT (OCT3), extraneuronal transporter, originally known as uptake 2 OCTl, OCT2, organic cation transporters Epi, epinephrine NE, norepinephrine DA, dopamine.
