In the present study, we found that lipid peroxidation and inflammation were induced in the brain of mouse model for Down syndrome(DS) at 3 months of age. Although increased lipid peroxidation was not detected in the brain of 1 month-old mouse model for DS, increased inflammation was observed in embryonic mouse brain with DS, suggesting that increased lipid peroxidation and inflammation would be independent in each other. Neuroinflammation in the DS brain could be therapeutic target for developmental retardation of DS brain and memory and learning impairment in DS patients.

在本研究中，我们发现，脂质过氧化和炎症反应诱导的唐氏综合征（DS）小鼠模型在3个月大的大脑。尽管在1月龄DS小鼠模型的脑中未检测到脂质过氧化增加，但在DS胚胎小鼠脑中观察到炎症增加，表明脂质过氧化增加和炎症将彼此独立。DS脑内的神经炎症可能是DS脑发育迟缓和DS患者记忆和学习障碍的治疗靶点。
