“…Restoration of opioid-induced GLT-1 deficits with chronic administration of the cysteine pro-drug, N-acetylcysteine, was also effective in reducing heroin seeking (Murray et al, 2012; Reissner et al, 2015; Zhou and Kalivas, 2008). Interesting, both ceftriaxone and N-acetylcysteine display anti-inflammatory properties making it difficult to disentangle their ability to suppress immune activation from their effects on restoring glutamate homeostasis (Csontos et al, 2012; Karalija et al, 2014; Kaur and Prakash, 2017; Lujia et al, 2014; Mahmoud and Ammar, 2011; Purwanto and Prasetyo, 2012; Wei et al, 2012). Regardless, it seems that opioid-induced immune activation and disrupted glutamate homeostasis may be interrelated phenomena that alter neuronal functioning ultimately influencing the behavioral effects of acute and chronic opioid administration.…”
