Adolescent Binge Ethanol Exposure Confers Lasting Adult Alcohol Tolerance due to Neuroimmune Activation: Reversal by Inhibition of HMGB1.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Epidemiological studies suggest heavy adolescent binge drinking is strongly associated with later development of an alcohol use disorder (AUD). Alcohol tolerance (i.e., an acquired reduction in acute alcohol responsivity) is a universally recognized symptom of AUD, but the direct contribution of adolescent binge drinking to adult alcohol tolerance is poorly understood. To investigate the contributions of adolescent binge ethanol exposure to lasting acquisition of acute tolerance, we used our ethanol response battery (ERB) to assess intoxication rating, hypothermia, motor coordination and balance across cumulative ethanol doses (i.e., 0.0, 0.5, 1.0, 2.0 and 3.0 g/kg) in adult female Wistar rats following adolescent intermittent ethanol (AIE), lipopolysaccharide (LPS) and glycyrrhizic acid treatment following AIE. We report AIE confers lasting alcohol tolerance across cumulative ethanol doses and blunts acute ethanol-induced increases in proinflammatory HMGB1 plasma levels. Adolescent LPS (1.0 mg/kg, i.p.) treatment, which mimics AIE-induced HMGB1-mediated neuroinflammation, induces adult alcohol tolerance and blunts HMGB1 release across cumulative ethanol doses on the ERB. Assessment of proinflammatory HMGB1 involvement in AIE-induced acquisition of lasting alcohol tolerance showed that post-AIE administration of the HMGB1 inhibitor glycyrrhizic acid reversed the AIE-induced acquisition of alcohol tolerance in adulthood. These data reveal that (1) adolescent binge drinking confers long-lasting low ethanol responsivity (i.e., tolerance), (2) proinflammatory neuroimmune activation contributes to the development of alcohol tolerance and (3) blockade of proinflammatory HMGB1 signalling reverses AIE-induced acquisition of alcohol tolerance in adulthood. These findings suggest a potential mechanistic target for the development of novel therapeutics for the treatment of AUD.
