Interferons play a major role in microglial-mediated neuroinflammation in Alzheimer's disease (AD). We investigated the interferon transcriptome (AD versus non-AD) using N9 and murine microglia. We identified 64 interferon-related differentially expressed genes (DEG) in LPS-stimulated N9 microglia versus control cells, 26 DEG in microglia from 5XFAD versus wild-type mice, with 13 DEG common to both datasets. Network analyses identified potential key mediators (Cxcl10, Ifit3) of the interferon response in AD. Gene-drug interaction analysis identified therapeutics targeting interferon-related genes. These data characterize the microglial interferon response in AD, providing new targets and therapeutics directed towards interferon-related neuroinflammation in AD.
干扰素在阿尔茨海默病(AD)中的小胶质细胞介导的神经炎症中发挥重要作用。我们使用 N9 和小鼠小胶质细胞研究了干扰素转录组(AD 与非 AD)。我们在 LPS 刺激的 N9 小胶质细胞与对照细胞中鉴定出 64 个干扰素相关差异表达基因(DEG),在 5XFAD 小鼠与野生型小鼠的小胶质细胞中鉴定出 26 个 DEG,两个数据集共有 13 个 DEG。网络分析确定了 AD 中干扰素反应的潜在关键介质(Cxcl10、Ifit3)。基因-药物相互作用分析确定了针对干扰素相关基因的治疗方法。这些数据描述了 AD 中小胶质细胞的干扰素反应,为针对 AD 中与干扰素相关的神经炎症的新靶点和治疗方法提供了信息。
