This article may help explain addiction science through research on opioid, alcohol, dopamine, brain science. The source abstract begins by describing: “Opioid-alcohol polysubstance use is prevalent and worsens treatment outcomes.”
Key finding: Thus, alcohol alters the motivation to seek oxycodone in a sex-dependent manner and the neural circuitry engaged by cue-primed reinstatement of sucrose and oxycodone-seeking.
Why this may help: This may help explain why addiction can involve brain, behavior, mental health, craving, relapse, or treatment factors rather than simple willpower alone. It should be read as research information, not personal medical advice.
This article may help explain addiction science through research on opioid, alcohol, dopamine, brain science. The source abstract begins by describing: “The mechanisms contributing to alcohol use disorder (AUD) are complex and the orexigenic peptide ghrelin, which enhances alcohol reward, is implied as a crucial modulator.”
Key finding: Collectively, our data show that DAG attenuates alcohol-related responses in rodents, an effect opposite to that of ghrelin, and contributes towards a deeper insight into behaviors regulated by the ghrelinergic signaling pathway.

This article may help explain addiction science through research on opioid, cocaine, brain science, withdrawal. The source abstract begins by describing: “Persistent vulnerability to drug-seeking is driven by enduring synaptic adaptations, yet current μ-opioid receptor-targeting pharmacotherapies provide limited efficacy against these neuroadaptations.”
Key finding: By targeting a pathway independent of classical opioid receptor signaling, CA4 inhibition represents a mechanistically distinct strategy that may reduce relapse vulnerability in OUD.

This article may help explain addiction science through research on opioid, cocaine, dopamine, brain science. The source abstract begins by describing: “Persistent transcriptional events in ventral tegmental area (VTA) and other reward relevant brain regions contribute to enduring behavioral adaptations that characterize substance use disorder.”
Key finding: These findings establish an essential role for H3Q5dop, and its downstream transcriptional consequences, in heroin-induced functional plasticity in VTA.

This article may help explain addiction science through research on opioid, alcohol, nicotine, brain science. The source abstract begins by describing: “Preclinical and human studies indicate psilocybin may reduce perseverant maladaptive behaviors, including nicotine and alcohol seeking.”
Key finding: We conclude that psilocybin reduces heroin relapse and highlight IL-17a signaling as a potential downstream pathway of psilocybin that also reduces heroin seeking.

This article may help explain addiction science through research on opioid, brain science, withdrawal, relapse. The source abstract begins by describing: “Opioid use disorder (OUD) is a chronic relapsing disorder that is a major burden for the lives of affected individuals, and society as a whole.”
Key finding: Altogether, these animal models will contribute to study behavioural and neuronal circuitries involved in the several negative affective signs characterizing OUD.
