Stress is central to many neuropsychiatric conditions, including alcohol use disorder (AUD). Stress influences the initiation and continued use of alcohol, the progression to AUD, and relapse. Identifying the neurocircuits activated during stress, and individual variability in these responses is critical for developing new treatment targets for AUD, particularly to mitigate stress-induced relapse.

Background: Chronic and excessive alcohol consumption is the leading cause of death due to chronic liver disease. Alcohol-related liver disease (ALD) encompasses a broad spectrum of clinical and pathological features, ranging from asymptomatic and reversible pathologies to hepatocellular carcinoma (HCC), a highly prevalent and deadly liver cancer. Indeed, alcohol consumption is one of the main worldwide etiologies of HCC.

and are mostly cultivated in tropical climates for culinary and perfumery purposes, yet their potential medicinal properties remain underreported. The aim of this study was to examine the antioxidant and immunomodulatory activities of ethanol extracts from (EESC) and (EEPC). Reflux extraction was carried out using 96% ethanol on the collected plant specimens to produce EESC and EEPC.

Alcohol use disorder is associated with altered function of cortical-amygdala-striatal circuits such as the orbitofrontal cortex (OFC), basolateral amygdala (BLA) and their connections to the dorsal medial striatum (DMS) shown to be involved in goal-directed actions. Using retrobead tracing, we previously reported enhanced excitability of DMS-projecting OFC neurons in mice following 3-to-7-day withdrawal from chronic intermittent ethanol (CIE) exposure. In the same animals, spiking of DMS-projecting BLA neurons was decreased at 3-days post-withdrawal followed by an increase in firing at 7- and 14-days.

Background And Aims: Alcohol-related liver disease (ALD) is one of the leading causes of severe liver disease with limited pharmacological treatments for alcohol-related steatohepatitis (ASH). CD44, a glycoprotein mainly expressed in immune cells, has been implicated in multiple inflammatory diseases but has never been studied in the ALD context. We therefore studied its contribution to ASH development in mice and its expression in ALD patients.
