Research focus
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.
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: “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.

This article may help explain addiction science through research on opioid, alcohol, dopamine, brain science. The source abstract begins by describing: “It is well documented that ethanol exposure alters GABA (γ-aminobutyric acid)-releasing synapses, and ethanol addiction is associated with endogenous opioid system.”
Key finding: These neuroadaptations to ethanol might contribute to early stage of addiction.

This article may help explain addiction science through research on alcohol, cannabis, nicotine, dopamine. The source abstract begins by describing: “In this Opinion article, Nutt and colleagues examine the history of and current evidence for the dopamine theory of addiction.”
Key finding: These observations have implications for understanding reward and treatment responses in various addictions.

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.
