Abstract
Abuse of and addiction to psychostimulants remains a challenging clinical issue; yet no effective pharmacotherapy is available. Trace amine associated receptor 1 (TAAR 1) is increasingly recognized as a novel drug target that participates in the modulation of drug abuse. This review analyzed existing preclinical evidence from electrophysiological, biochemical to behavioral aspects regarding the functional interactions between TAAR 1 and dopaminergic system. TAAR 1 knockout mice demonstrate increased sensitivity to dopaminergic activation while TAAR 1 agonists reduce the neurochemical effects of cocaine and amphetamines, attenuate abuse- and addiction-related behavioral effects of cocaine and methamphetamine. It is concluded that TAAR 1 activation functionally modulates the dopaminergic activity and TAAR 1 agonists appear to be promising pharmacotherapies against psychostimulant addiction.Entities:
