Research focus
This article may help explain addiction science through research on alcohol, cocaine, methamphetamine, brain science. The source abstract begins by describing: “The central nucleus of the amygdala (CeA) is a key hub of the neural circuitry regulating alcohol and stress interactions.”
Key finding: Together, these data identify CeA CART cells as a subpopulation of PKCδ cells that influence stress × alcohol interactions and mediate stress-induced alcohol seeking behaviours.
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, cocaine, methamphetamine, dopamine. The source abstract begins by describing: “Substance use disorder (SUD) represents a substantial challenge in neuropsychiatric medicine, with the molecular mechanisms underlying its etiology remaining elusive.”
Key finding: Our findings highlight the significant role of circHomer1 in regulating cocaine reward and identify a novel molecular regulator of the actions of cocaine on the brain’s reward circuitry, providing a new strategy for treating drug addiction.

This article may help explain addiction science through research on opioid, cocaine, methamphetamine, dopamine. The source abstract begins by describing: “Methamphetamine (METH) is a widely abused psychostimulant, whose hyper-rewarding property is believed to underlie its addictive effect, but the molecular mechanism regulating this effect remains unclear.”
Key finding: Our findings demonstrate an important role for NAc novel-m009C in regulating METH reward, reveal a novel molecular regulator of the actions of METH on brain reward circuitries and provide a new strategy for treating METH addiction based on the modulation of small non-coding RNAs.

This article may help explain addiction science through research on opioid, alcohol, cocaine, methamphetamine. The source abstract begins by describing: “Substance use disorders (SUDs) are common and costly conditions that are partially attributable to genetic factors.”
Key finding: Overall, the findings highlight similarities and differences in immunogenetic profiles of SUDs that may influence the prevalence and co-occurrence of problematic SUDs and may contribute to assessment of SUD risk of an individual on the basis of their HLA genetic makeup.

This article may help explain addiction science through research on alcohol, cannabis, brain science, withdrawal. The source abstract begins by describing: “Alcohol use disorder (AUD) remains a pervasive public health issue with limited effective treatments.”
Key finding: These findings indicate that chronic CBD administration attenuates both behavioral and neurobiological facets of alcohol dependence by modulating neuronal excitability and preventing neurodegeneration, supporting its therapeutic potential for AUD and providing mechanistic insights for future research.

This article may help explain addiction science through research on cocaine, brain science, craving, relapse. The source abstract begins by describing: “Cocaine use disorder represents a public health crisis with no FDA-approved medications for its treatment.”
Key finding: These findings suggest that gut bacteria, via their metabolites, are key regulators of drug-seeking behaviors, positioning the microbiome as a potential translational research target.
