Microarray dataset of gene transcription in mouse microglia and peripheral monocytes in contextual fear conditioning

The transcription profile of microglia related to fear conditioning remains unclear. Here, we used Illumina MouseWG-6v2 microarrays to investigate the gene transcription changes in microglia and peripheral monocytes after contextual fear conditioning of C57BL/6 J mice. Mice were trained with or without a single minimized footshock stimulation (0-s or 2-s, 0.4 mA) and re-exposed to the training context without footshock for three different durations 24 h later: 0 min (FS0), 3 min (FS3), or 30 min (FS30). Whole brain microglia and peripheral monocytes were prepared 24 h after re-exposure using a neural tissue dissociation kit, including non-footshock controls for two re-exposure durations (Con3 and Con30). The data can be valuable for researchers interested in glial cells and neurotransmission studies and are related to the research article “Contextual fear conditioning regulates synapse-related gene transcription in mouse microglia”.
