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...

The Role of Innate Immunity in Alcoholic Liver Disease

Heavy consumption of alcohol poses a well-known health risk worldwide. Alcohol’s effects on health and well-being are numerous and include injuries and fatalities resulting from alcohol-induced incapacitation. Moreover, chronic and heavy alcohol consumption affects the integrity and function of vital tissues and organs, causing slow but significant structural and functional damage over time. One...

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...

Alcohol’s Burden on Immunity Following Burn, Hemorrhagic Shock, or Traumatic Brain Injury

The incidence of traumatic injury in alcohol-intoxicated individuals continues to escalate. According to the Centers for Disease Control and Prevention (2012a), more than 38 million American alcohol users consume 5 or more drinks on the same occasion (i.e., binge drink) and do so about 4 times per month. This behavior is highly conducive to unintentional or accidental traumatic injury, which...

The First Line of Defense: The Effects of Alcohol on Post-Burn Intestinal Barrier, Immune Cells, and Microbiome

Each year 2.5 million people die from alcohol abuse and its related morbidities worldwide, making alcohol related deaths among the highest preventable causes of death, and the greatest cause of premature death and disability in men between ages 15 and 59 (World Health Organization 2011). Alcohol abuse predisposes individuals to life-threatening conditions such as alcoholic liver disease (ALD)...

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...

NIH’s Adolescent Brain Cognitive Development Study (ABCD Study)

ABCD Study logo

Adolescence is the stage of life during which most people begin using alcohol, and it is also a time of considerable social, psychological, and physiological change. The brain, particularly the frontal cortex, continues to develop throughout adolescence and does not fully mature until early adulthood. Adolescent alcohol exposure can impair brain development, compromise short- and long-term...

“Maturing Out” of Binge and Problem Drinking

This article reviews literature aiming to explain the widespread reductions in binge and problem drinking that begin around the transition to young adulthood (i.e., “maturing out”). Whereas most existing literature on maturing out emphasizes contextual effects of transitions into adult roles and responsibilities, this article also reviews recent work demonstrating further effects of young adult...

The Epidemiology of Binge Drinking Among College-Age Individuals in the United States

Rates of alcohol consumption continue to be a concern, particularly for individuals who are college age. Drinking patterns have changed over time, with the frequency of binge drinking (consuming four/five or more drinks for women/men) remaining high (30% to 40%). Young adults in the college age range are developmentally and socially at higher risk for drinking at binge levels. Changes in autonomy...

Drinking Patterns and Their Definitions

The number of drinks a person consumes and the rate at which he or she consumes them influence how much alcohol enters the brain and how impaired that person becomes. Many people are surprised to learn what counts as a drink. The amount of liquid in one’s glass, can, or bottle does not necessarily match up to how much alcohol is in the drink. To facilitate research and clinical care and to help...
