[Abstract] dA6m DNA immunoprecipitation followed by deep sequencing (DIP-Seq) is a key tool in identifying and studying the genome-wide distribution of N6-methyldeoxyadenosine (dA6m). The precise function of this novel DNA modification remains to be fully elucidated, but it is known to be absent from transcriptional start sites and excluded from exons, suggesting a role in transcriptional regulation (Koziol et al., 2015). Importantly, its existence suggests that DNA might be more diverse than previously believed, as further DNA modifications might exist in eukaryotic DNA (Koziol et al., 2015). This protocol describes the method to perform dA6m DNA immunoprecipitation (DIP), as was applied to characterize the first dA6m ...
[摘要] 原代小胶质细胞，在单一培养或与神经元或星形胶质细胞共培养，是研究在中枢神经系统（CNS）中小胶质炎症反应和细胞类型特异性相互作用的机制的强大工具。这个协议提供了如何从新生小鼠幼崽制备高纯度原代小胶质细胞的细节。总的步骤包括脑细胞解离，混合胶质细胞培养和小胶质细胞分离。
[背景] 近年来，神经炎症已成为神经科学研究的热点领域。在患有各种神经疾病的患者的脑中观察到炎症反应，例如神经胶质激活和细胞因子上调（Fan等人，2015; Koshimori等人，2015;花园和坎贝尔，2016）。神经炎症不仅被认为是脑中病理变化的结果，而且也是疾病进展的原因（Schwartz等人，2013）。此外，炎症通路的生理功能，其重要性以前被低估，正被揭示为惊人的多才多艺。例如，补体信号通路的激活通常在神经疾病的中枢神经系统（CNS）中观察到，并且被怀疑参与疾病病理生理学（Michailidou等人，2015; Loeffler ...
