| Popis | Background Alcohol use disorder (AUD) has been associated with Alzheimer’s disease (AD) and dementia, yet the underlying mechanisms and specific role of ethanol in AD progression remain poorly understood. Neuroinflammation has emerged as a key contributor to both AD pathogenesis and ethanol-induced brain damage. Activation of innate immune cells and signaling pathways, in particular NLRP3 inflammasome, plays a pivotal role in both AD and ethanol-induced inflammation. Thus, we postulated that excessive ethanol consumption could contribute to AD progression via amplified neuroinflammation. Methods The 12–15-month-old WT and APP/PS1 mice received water or ethanol (3.5 g/kg) binge every alternate day for a period of one month. The effects of ethanol on amyloid pathology, microglia and astrocyte activation, and NLRP3 inflammasome activation were evaluated in the mouse brains. The effect … |
