Abstract. Dopamine D2-autoreceptors play a key role in regulating the activity of dopamine neurons and control the synthesis, release and uptake of dopamine. These G i/o-coupled inhibitory receptors play a major part in shaping dopamine transmission.2-autoreceptors also regulate dopamine transmission by increasing the activity of DAT (Cass and Gerhardt, 1994, Dickinson et al., 1999, Mayfield and Zahniser, 2001, Schmitz et al., 2002, Wu et al., 2002 and Benoit-Marand et al., 2011).
