Serotonin (5-hydroxytryptamine; 5-HT) is a key neuromodulator involved in the regulation of mood, appetite, aggression, and impulse control. Dysregulation of central 5-HT function has been implicated in alcohol use disorder (AUD) and comorbid depression. This review summarizes clinical and preclinical evidence on the role of 5-HT in AUD development, heterogeneity, and treatment response....
The lack of selective pharmacological tools has limited the full unraveling of G protein-coupled receptor 18 (GPR18) functions. The present study was aimed at discovering the activities of three novel preferential or selective GPR18 ligands, one agonist (PSB-KK-1415) and two antagonists (PSB-CB-5 and PSB-CB-27). We investigated these ligands in several screening tests, considering the...
Chronic methamphetamine (meth) abuse often turns into a compulsive drug-taking disorder accompanied by persistent cognitive deficits and re-occurring psychosis. Possible common neurobiological substrates underlying meth-induced deficits and schizophrenia remain poorly understood. Serotonin 2A (5-HT2A) and metabotropic glutamate 2 (mGlu2) receptors co-regulate psychosis-like behaviors and...
