This study shows chronic alcohol exposure increases social avoidance in male mice by enhancing serotonergic inputs to the nucleus accumbens, which inhibits dopamine release and reduces social motivation.

The paper examines how chronic ethanol exposure affects ACE2 and TMPRSS2 expression in specific brain regions, suggesting increased vulnerability to SARS-CoV-2 neuroinvasion.

This study shows that adolescent ethanol exposure in mice leads to long-term pain sensitivity, neuroinflammation, and serotonergic deficits, with microglial activation in the dorsal raphe nucleus as a key driver.
