“…OCT3 expression has also been observed on DAT+ neurons (Mayer et al., 2018), suggesting possible co‐expression at dopamine terminals. Interestingly, OCT3 also appears to be present on striatal cholinergic neurons (Vialou, Balasse, Dumas, Giros, & Gautron, 2007), which strongly regulate terminal dynamics in the nucleus accumbens (Melchior, Ferris, Stuber, Riddle, & Jones, 2015; Siciliano, McIntosh, Jones, & Ferris, 2017; Yorgason, Rose, McIntosh, Ferris, & Jones, 2015). Therefore, it is possible that there may be additional effects of OCT3 activity on cholinergic neurons, which may alter catecholamine clearance kinetics.…”
