Exposure to lipopolysaccharides (LPS) during pregnancy have been linked to alterations in the offspring's central nervous system. Cherries are a source of anthocyanins, which possess neuroprotective properties. The study aimed to evaluate the neuroprotective effects of cherry juice (CJ) on memory and hippocampal cell counts in offspring exposed to LPS during gestation and the gestation-lactation periods. At postnatal day 90, rat pups were divided into five groups: Control (saline solution), LPS-G (LPS during gestation), LPS-G+CJ (LPS during gestation+CJ), LPS-GL (LPS during gestation-lactation), and LPS-GL+CJ (LPS during gestation-lactation+CJ). A battery of behavioral tests was conducted to assess short- and long-term memory and anxiety-like behavior. Histological analysis was performed on hippocampal regions. Leukocyte levels were measured as markers of systemic inflammation. Results showed that pups in the LPS-G and LPS-GL groups exhibited impaired memory, increased anxiety-like behavior, elevated leukocyte levels, and reduced cell counts in the dentate gyrus and CA1 regions, as well as in CA2 (LPS-G) and CA3 (LPS-GL). Cherry juice administration in the LPS-G+CJ and LPS-GL+CJ groups improved memory performance, normalized leukocyte levels, and restored hippocampal cell counts. These findings suggest that cherry juice exerts neuroprotective effects against LPS-induced neuroinflammation during gestation and the gestation-lactation periods.
孕期暴露于脂多糖(LPS)与后代中枢神经系统的改变有关。樱桃是花青素的来源,具有神经保护特性。本研究旨在评估樱桃汁(CJ)对孕期及妊娠哺乳期暴露于LPS的后代的记忆和海马细胞计数的神经保护作用。在出生后第90天,将幼鼠分为五组:对照组(生理盐水)、LPS-G组(孕期暴露于LPS)、LPS-G+CJ组(孕期暴露于LPS+CJ)、LPS-GL组(妊娠哺乳期暴露于LPS)和LPS-GL+CJ组(妊娠哺乳期暴露于LPS+CJ)。进行了一系列行为测试以评估短期和长期记忆以及焦虑样行为。对海马区域进行了组织学分析。测量白细胞水平作为全身炎症的标志物。结果表明,LPS-G组和LPS-GL组的幼鼠表现出记忆受损、焦虑样行为增加、白细胞水平升高,齿状回和CA1区域以及CA2(LPS-G组)和CA3(LPS-GL组)的细胞计数减少。LPS-G+CJ组和LPS-GL+CJ组给予樱桃汁可改善记忆表现、使白细胞水平正常化并恢复海马细胞计数。这些发现表明,樱桃汁对孕期及妊娠哺乳期LPS诱导的神经炎症具有神经保护作用。
