Introduction: Nitrous oxide (N2O) abuse is a growing international concern, with limited effective intervention strategies. This study investigates the potential of Cryptotanshinone (CTS) and its metabolite tanshinone IIA (TAN IIA) in alleviating N2O-induced conditioned place preference (CPP) behavior and modulating dopamine D1 receptor (D1R) and TrkB pathway Methods: In vivo, a CPP mouse model...
Recreational use of nitrous oxide (N2O) has risen dramatically over the past decades. This study aimed to examine its rewarding effect and the underlying mechanisms. The exposure of mice to a subanesthetic concentration (20%) of N2O for 30 min for 4 consecutive days paired with N2O in the morning and paired with the air in the afternoon produced apparent rewarding behavior in the conditioned...
The development of ketamine-like rapid antidepressants holds promise for enhancing the therapeutic efficacy of depression, but the underlying cellular and molecular mechanisms remain unclear. Implicated in depression regulation, the neuropeptide pituitary adenylate cyclase-activating polypeptide (PACAP) is investigated here to examine its role in mediating the rapid antidepressant response. The...
Aberrant neuronal Sigma-1 receptor (Sig-1r)-mediated endoplasmic reticulum (ER)- mitochondria signaling plays a key role in the neuronal cytopathology of Alzheimer's disease (AD). The natural psychedelic N, N-dimethyltryptamine (DMT) is a Sig-1r agonist that may have the anti-AD potential through protecting neuronal ER-mitochondrial interplay. 3×TG-AD transgenic mice were administered with...
