Summary: The mu opioid receptor antagonist/kappa opioid receptor (KOR) partial agonist nalmefene (NMF) did not significantly reduce cocaine intake, but acute pretreatment of 1 mg/kg NMF significantly potentiated cocaine motivation. Further research with KOR selective partial or full agonists is required to determine their effect on cocaine reinforcement.

Summary: This study investigated transcriptional and functional changes of the mu opioid receptor in reward-related brain regions induced by intravenous cocaine self-administration in rats. The findings revealed increased mu opioid receptor gene expression and enhanced functionality in the hippocampus of cocaine self-administering animals. The study highlights the hippocampus as an important target for further investigation of neuroadaptive processes leading to cocaine addiction.

Summary: Research has shown that the neurosteroid DHEA has a long-lasting effect on reducing cocaine-seeking behavior and has a positive impact on hippocampal cell structure. The study emphasizes the critical role of astrocytes and neurons in overcoming addiction behavior.

Summary: PPL-103 has shown potential as a pharmacotherapy for the treatment of cocaine use disorder (CUD). It reduces self-administration of cocaine, decreases motivation for cocaine, and attenuates binge-like cocaine taking. PPL-103 also reduces priming- and cue-induced reinstatement of cocaine seeking. Tolerance development was not observed with repeated PPL-103 treatment.

Summary: The study utilized RNA sequencing to analyze brain regions in subjects with OUD, identifying gene transcription related to synaptic remodeling and neuroinflammation. Microglia were implicated as a potential driver for opioid-induced neuroplasticity, with genetic liabilities for risky behavior, ADHD, and depression found in individuals with OUD.

Summary: Research using reduced complexity cross (RCC) strategy has accelerated the discovery of genes related to cocaine addiction traits in rat substrains. By validating differences in compulsive-like behavior and cocaine self-administration traits between two substrains, the effectiveness of using RCC approach has been confirmed.

Summary: This study evaluated the impact of cocaine on thiols and reactive sulfur species in the liver and kidney of rats, finding that cocaine leads to a decrease in reactive sulfur species in the liver and an increase in the kidney, with these changes being maintained during drug abstinence. Additionally, cocaine alters cysteine metabolism towards an anaerobic pathway in the kidney.

Summary: The KOR is involved in the regulation of reward and mood, and drug abuse increases its activation. Long-acting KOR antagonists have been shown to alleviate withdrawal symptoms, but their use in humans comes with safety concerns. This study found that a short-acting KOR antagonist showed efficacy in reducing withdrawal behavior in mice, and computational studies provided insights for the design of future antagonists.

Summary: Substance use disorders and traumatic stress-related pathologies often coexist. The KOR and DYN play a crucial role in this comorbidity, regulating the effects of stress and drug use. The DYN/KOR system is involved in anxiety, depressive symptoms, conditioned fear response, and negative reinforcement after drug use. KOR activation leads to drug-seeking behavior and cross-regulates with corticotropin-releasing factor. The sexual dimorphism of the DYN/KOR system may contribute to gender differences in patients with SUD or/and traumatic stress-related pathologies. Antagonists targeting KOR could be a promising pharmacological strategy for treating this comorbidity.

Summary: Intermittent access (IntA) models have been developed to mimic human cocaine use and have been shown to enhance pharmacological and behavioral effects of cocaine. This study examined sex differences and cue extinction in the IntA model. Results showed that IntA increased motivation for cocaine in females and facilitated punished cocaine self-administration in males. Additionally, after 10 days of IntA training, drug-seeking was dependent on DLS dopamine in males. These findings suggest that IntA is valuable for studying sex differences and early stages of drug use.

Summary: This study found changes in NMDA receptor subunit levels following cocaine abstinence with extinction training, particularly an increase in GluN2A subunit levels in the postsynaptic density fraction, without changing the expression of Grin1 and Grin2A genes in related brain structures. The modulation of NMDA receptor subunits observed after cocaine abstinence with extinction training may be a potential target for cocaine-seeking behavior.

Summary: Cannabinoid CB2 receptors are involved in drug reward and addiction. Repeated cocaine exposure increases CB2R expression in the brain and spleen, while repeated heroin administration leads to a dose-dependent reduction in CB2 mRNA expression in the striatum. Upregulation of CB2R mainly occurs in D-1-MSNs, not in D-2-MSNs or microglia.

Summary: Recent studies suggest that the abrupt cessation of selective serotonin reuptake inhibitors can increase alcohol consumption after an alcohol deprivation period in rats, while the effect of cessation of selective noradrenaline reuptake inhibitors remains unknown. The interruption of subchronic treatment with SNRIs reboxetine led to increased ethanol intake in animals, associated with dysregulation of endocannabinoid/glutamate signaling. This finding could be important for comorbid AUD/MD patients to carefully monitor antidepressant therapy to avoid unwanted effects.

Summary: This study investigated the expression of APOE4 and reelin, as well as cognitive function, in patients with alcohol use disorder (AUD) and controls. The results showed that APOE4 expression levels were similar between patients and controls, but levels of clusterin and reelin were higher in patients with AUD. Multivariate logistic regression analysis identified reelin as a good indicator of cognitive impairment in early abstinence. During a 6-month abstinence period, reelin levels decreased in patients with AUD and cognitive function improved.
