Binge ethanol consumption-associated behavioral impairments in male mice using a gelatin-based drinking-in-the dark model.

Alcohol 2021 May 21. Epub 2021 May 21.

Department of Pharmacodynamics, University of Florida, Gainesville, FL 32610. Electronic address:

Background: Acute intoxication caused by binge ethanol drinking is linked to widespread impairments in brain functions. Various alcohol administration paradigms have been used in animals to model the heterogenous clinical manifestation of intoxication in people. It is challenging to model a procedure that produces "visible intoxication" in rodents; however manipulation of variables such as route of alcohol administration, time of availability, frequency, duration and amount of ethanol exposure have achieved some success.

Deficit of β-endorphin neurons in the hypothalamus and high expression of MOR in mesolimbic structures are related to high alcohol consumption in outbred rats.

Alcohol 2021 May 19;95:1-6. Epub 2021 May 19.

Laboratorio de Farmacología y Conducta, Instituto de Neurociencias, CUCBA, Universidad de Guadalajara, Guadalajara, Jalisco, 44130, México. Electronic address:

Clinical studies have postulated that β-endorphin deficiency generates excessive alcohol consumption, and it has been shown that the reduction of β-endorphin neurons increases alcohol intake in animal models. The β-endorphin produce their rewarding effect when they act mainly on the μ-opioid receptors (MOR) located in mesolimbic structures. Thus, it is possible that individual differences in these components of the endogenous opioid system are related to different levels of alcohol consumption. Read More

Effects of ceftriaxone on ethanol drinking and GLT-1 expression in ethanol dependence and relapse drinking.

Alcohol 2021 May 16;92:1-9. Epub 2021 Jan 16.

Charleston Alcohol Research Center, Department of Psychiatry and Behavioral Sciences, Medical University of South Carolina, Charleston, SC, United States; Department of Neuroscience, Medical University of South Carolina, Charleston, SC, United States; Ralph A. Johnson Veterans Administration Medical Center, Charleston, SC, United States.

Repeated cycles of chronic intermittent ethanol (CIE) exposure increase voluntary consumption of alcohol (ethanol) in mice. Previous reports from our laboratory show that CIE increases extracellular glutamate in the nucleus accumbens (NAc) and that manipulating accumbal glutamate concentrations will alter ethanol drinking, indicating that glutamate homeostasis plays a crucial role in ethanol drinking in this model. A number of studies have shown that ceftriaxone increases GLT-1 expression, the major glutamate transporter, and that treatment with this antibiotic reduces ethanol drinking. Read More
