Differential sensitivity of monoamine transport systems to inhibitors in PHT and BeWo cells. Uptake of serotonin (A, B), norepinephrine (C, D), and dopamine (E, F) recorded in the presence of 100 µM paroxetine (PRX), 20 nM nisoxetine (NIS), 50 nM GBR 12935, 100 µM decynium-22 (D22), and 100 µM cortisol (CORT). Values are percentages of the recorded uptake by inhibitor-free controls (CTRL). Presented data are means ± SD (n ≥ 4), with indications of statistical significance obtained from paired t-tests compared to CTRL: *p ≤ 0.05, **p ≤ 0.01
