However, the potential contribution of PSD-95 to EtOH-related behaviors has not been established. Here, we evaluated knockout (KO) mice lacking PSD-95 for multiple measures of sensitivity to the acute intoxicating effects of EtOH (ataxia, hypothermia, sedation/hypnosis), EtOH drinking under conditions of free access and following deprivation, acquisition and long-term retention of EtOH conditioned place preference (CPP) (and lithium chloride-induced conditioned taste aversion), and intoxication-potentiating responses to NMDAR antagonism. PSD-95 KO exhibited increased sensitivity to the sedative/hypnotic, but not ataxic or hypothermic, effects of acute EtOH relative to wild-type controls (WT). PSD-95 KO consumed less EtOH than WT, particularly at higher EtOH concentrations, although increases in KO drinking could be induced by concentration-fading and deprivation. PSD-95 KO showed normal EtOH CPP 1 day after conditioning, but showed significant aversion 2 weeks later. MK-8776 order Lithium chloride-induced taste aversion was impaired in PSD-95 KO at both time points. Finally, the EtOH-potentiating effects of the NMDAR antagonist Thymidine kinase MK-801 were intact in PSD-95 KO at the dose tested. These data reveal a major, novel role for PSD-95 in mediating EtOH behaviors, and add to growing evidence that PSD-95 is a key mediator of the effects of multiple abused drugs. ""Aims? Impaired ability to form associations between negative events in gambling and aversive somatic reactions may be a predisposing factor for pathological gambling. The current study investigated whether a group of pathological gamblers and a control group differed in aversive classical conditioning. Design? A differential aversive classical conditioning paradigm, which consisted of three phases. In the habituation phase, one 850-Hz tone stimulus and one 1500-Hz tone stimulus were presented three times each in random order. In the acquisition phase, the two tones were presented 10 times each in random order, and one was always followed by a 100-dB burst of white noise. In the extinction phase the two tones were presented three times each without the white noise. Setting? University Quizartinib laboratory testing facilities and out-patient treatment facilities. Participants? Twenty pathological gamblers and 20 control participants. Measurements? Duration of seven cardiac interbeat-intervals (IBIs) following tone offset, gambling severity, tobacco and alcohol use, anxiety and depression. Findings? No group differences were found in the habituation and acquisition phases. However, a significant group?��?stimuli?��?trials?��?IBIs interaction effect was found in the extinction phase (P?
