<i>Rubus occidentalis</i> Ethanol Extract Attenuates Neuroinflammation and Cognitive Impairment in Lipopolysaccharide-Stimulated Microglia and Scopolamine-Induced Amnesic Mice.

ABSTRACT: Background/Objectives: Neuroinflammatory mechanisms, primarily mediated by activated microglia, play a key role in the progression of conditions such as mild cognitive impairment associated with Alzheimer's disease. Rubus occidentalis (R. occidentalis), a black-fruited raspberry native to North America, is reported to possess antimicrobial, antidiabetic, and anticancer properties. This study investigated the neuroprotective and anti-neuroinflammatory effects of a 100% ethanol extract from premature R. occidentalis fruits (ROE) in lipopolysaccharide (LPS)-stimulated BV-2 microglial cells and a scopolamine-induced amnesic mouse model. Methods: C57BL/6N mice were orally administered ROE (100 or 200 mg/kg/b.w.) and donepezil (DNZ, 5 mg/kg) for 9 days and intr
