Nicotine self-administration is associated with decreased expression of the glial glutamate transporter 1 (GLT-1) and the cystine-glutamate exchange protein xCT in the nucleus accumbens core (NAcore). N-acetylcysteine (NAC), which is an antioxidant, anti-inflammatory, and glutamatergic agent, restores these proteins associated with increased relapse vulnerability. However, the specific molecular mechanisms driving NAC inhibitory effects on cue-induced nicotine reinstatement are unknown. Thus, the present study assessed NAC’s effects on cue-induced nicotine reinstatement are dependent on NAcore GLT-1 expression. Here, rats were treated with NAC in combination with intra-NAcore vivo-morpholinos to examine the role of GLT-1 in NAC-mediated inhibition of cue-induced nicotine seeking. …
