Alcohol and HIV Effects on the Immune System

Alcohol use disorder (AUD) and HIV infection both affect the immune system and frequently coexist in the same person, potentially multiplying the risk of infectious disease. Infectious disease, in turn, continues to be a major health concern and leading cause of morbidity and mortality worldwide, despite major advances in our understanding of the immune system, improvements in sanitation...

The Effects of Stress on Alcohol Consumption

This issue of Alcohol Research: Current Reviews focuses on the impact of stress on alcohol consumption. The significance of stress on alcohol abuse recently has been reemphasized by the alcohol use problems following posttraumatic stress disorder, such as those seen with some combat veterans. Behavior is described as an interaction between genetic constitution and environmental influences. Of the...

Neuroimmune Function and the Consequences of Alcohol Exposure

Induction of neuroimmune genes by binge drinking increases neuronal excitability and oxidative stress, contributing to the neurobiology of alcohol dependence and causing neurodegeneration. Ethanol exposure activates signaling pathways featuring high-mobility group box 1 and Toll-like receptor 4 (TLR4), resulting in induction of the transcription factor nuclear factor kappa-light-chain-enhancer of...

Alcohol and Puberty: Mechanisms of Delayed Development

Adolescence represents a vulnerable period for developing youth. Alcohol use and misuse are especially problematic behaviors during this time. Adolescents are more sensitive to alcohol and less tolerant of its detrimental effects than are adults. Research in humans and animals has revealed that early alcohol consumption can result in delayed pubertal development. Animal studies have shown that...

Effects of Alcohol on Tumor Growth, Metastasis, Immune Response, and Host Survival

Alcohol use and abuse have been implicated as etiological factors in the genesis of an increasing number of cancer types in both men and women. In 2012, the International Agency for Research on Cancer (IARC) listed both beverage alcohol (i.e., ethanol) and its major metabolite, acetaldehyde, as tumor-inducing substances (i.e., carcinogens) in humans. The most recent worldwide statistic from 2002...

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...

Epigenetic Control of Gene Expression in the Alcoholic Brain

Whether a specific gene is transcribed or repressed is determined by the specific status (i.e., conformational state) of the complex of chromosomal DNA and proteins (i.e., the chromatin) and by the recruitment of specific proteins (i.e., transcription factors) to regulatory sites on the DNA (Copeland et al. 2010). Chromatin states can change as a result of enzyme-mediated covalent modifications of...

Impact of Alcohol Abuse on the Adaptive Immune System

In the United States, alcohol use disorder (AUD) is the third-leading cause of preventable death. It is associated with increased susceptibility to bacterial pneumonia; viral infections, such as HIV and hepatitis C virus (HCV); and increased postoperative morbidity and mortality. This increased susceptibility is mediated in part by functional alterations in various cells of the immune system. The...

Early Life Stress as a Predictor of Co-Occurring Alcohol Use Disorder and Post-Traumatic Stress Disorder

During the critical developmental periods of childhood when neural plasticity is high, exposure to early life stress (ELS) or trauma may lead to enduring changes in physiological stress systems and enhanced vulnerability for psychopathological conditions such as post-traumatic stress disorder (PTSD) and alcohol use disorder (AUD) in adulthood. Clinical and preclinical studies have sought to...
