Epigenetic Targets for Reversing Immune Defects Caused by Alcohol Exposure

Extensive clinical and experimental data suggest that alcohol consumption has dose-dependent modulatory effects on the immune system that influence the two arms of the immune response (i.e., innate and adaptive immune responses). In many other organ systems, such as the brain and liver, alcohol consumption has been shown to alter factors that can modify gene expression without changing the DNA...

How Does Stress Lead to Risk of Alcohol Relapse?

It has long been known that stress increases the risk of alcohol relapse (Sinha 2001). Clinical observations, surveys, and epidemiological studies document an association between self-reports of stressors and subsequent return to drinking. Studies assessing alcohol relapse after treatment completion and discharge also indicate the contribution of highly stressful events independent of alcohol use...

Clinical Laboratory Stressors Used to Study Alcohol–Stress Relationships

A comprehensive understanding of the relationship between stress and alcohol use is important for understanding the risks of developing alcohol problems and subsequent relapse. Although the relationship is complex, substantial evidence supports that exposure to chronic stress early in life (e.g., Sher et al. 1997), adult trauma (Kessler et al. 1995), and the presence of anxiety disorders (Grant et...

Stress Glossary

Adrenocorticotropic hormone (ACTH): Also known as corticotropin, is a hormone produced and secreted by the anterior pituitary gland. It is an important component of the hypothalamic–pituitary–adrenal (HPA) axis and often is produced in response to biological stress (along with corticotropin-releasing factor from the hypothalamus). Its principal effects are increased production and release of...

Overview: Stress and Alcohol Use Disorders Revisited

In the 13 years since Alcohol Research & Health (now titled Alcohol Research: Current Reviews) first visited the topic of “Alcohol and Stress” (see Vol. 23, No. 4, 1999), there has been a sustained flow of new information in the field prompting us to publish this updated edition. Indeed, one could argue that this second look at the topic is long overdue. An entirely new lexicon of terms1 has been...

Childhood Trauma, Posttraumatic Stress Disorder, and Alcohol Dependence

Children exposed to severe adversity early in life are at increased risk of subsequently developing mental health problems, including alcohol dependence. In general, the onset of trauma precedes the onset of alcohol dependence. Although it is impossible to establish a direct causal relationship, this temporal relationship suggests a robust and positive relationship between exposure to early-life...

Genetic and Environmental Determinants of Stress Responding

The development of alcohol dependence is a complex process influenced by both genetic and environmental risk factors (Prescott and Kendler 1999). The relative contributions of genetic and environmental influences fluctuate across development. During adolescence the initiation of alcohol use is strongly influenced by environmental factors (Dick et al. 2007; Heath et al. 1997; Karvonen 1995...

Anxiety and Alcohol Use Disorders: Comorbidity and Treatment Considerations

Co-occurring anxiety disorders and alcohol use disorders (AUDs) are of great interest to researchers and clinicians. Cumulative evidence from epidemiological and clinical studies over the past few decades has highlighted both the frequency and clinical impact of this comorbidity. Investigations into the unique connections between specific anxiety disorders and AUDs have shown that this association...

Alcohol Dependence and Genes Encoding α2 and γ1 GABAA Receptor Subunits

Even though the consequences of alcohol dependence (AD) clearly are devastating and obvious to observers, the molecular mechanisms involved in the development of the disease are far from clear and understood. The search for these mechanisms is made even more difficult by the vast number of genes, proteins, and pathways in the human body that potentially could be involved, and by the obvious...

Identifying Genetic Variation for Alcohol Dependence

Over the last decade, three large-scale projects have catalyzed a revolution in genetic technologies and studies. First, the Human Genome Project laid the foundation for modern genetic studies of disease by determining the basic sequence of the 3 billion building blocks (i.e., base pairs) that make up the human genome and by identifying the approximately 25,000 genes included in this sequence (htt...
