Alcohol is frequently consumed for stress relief, but the individual determinants and the temporal course of stress-induced alcohol use are not well understood. Preclinical studies may help shed light on these factors. We synthesize here the findings from numerous rodent studies of stress and alcohol interactions. Stress-induced alcohol consumption is age-dependent, has a high genetic load, and results from an interaction of the stress and reward systems. Specifically, glucocorticoids, acting within the nucleus accumbens (NAc), are important mediators of this stress-induced alcohol intake. In addition, increased activation of the corticotropin-releasing hormone (CRH) system within the extended amygdala appears to mediate stress-induced relapse. Finally, these preclinical studies have helped to identify several attractive targets for novel treatments of alcohol abuse and addiction.

Chronic social defeat stress (SDS) is a widely employed preclinical model of depression involving repeated exposure to physical defeats using a resident-intruder model in male mice. Exposure to SDS induces depressive-like phenotypes including anhedonia, social withdrawal, and increased drug and alcohol consumption. Previously, we found that expression of the neurokinin-1 receptor (NK1R) is increased in the nucleus accumbens (NAC) of mice that are sensitive to this stressor and increase their alcohol intake.

The rising prevalence of neurodegenerative disorders underscores the urgent need for effective interventions to prevent neuronal cell death. This study evaluates the neuroprotective potential of phytosome-encapsulated 6-gingerol- and 6-shogaol-enriched extracts from Roscoe (6GS), bioactive compounds renowned for their antioxidant and anti-inflammatory properties. The novel phytosome encapsulation technology employed enhances the bioavailability and stability of these compounds, offering superior therapeutic potential compared to conventional formulations.

All--retinal (atRAL)-induced photoreceptor atrophy and retinal degeneration are hallmark features of dry age-related macular degeneration (AMD) and Stargardt disease type 1 (STGD1). The toxicity of atRAL is closely related to the generation of reactive oxygen species (ROS). Quercetin, a natural product, is known for its potent antioxidant properties; however, its effects in mitigating atRAL-mediated retinal damage remains unclear.
