Fig. 1: miRNA/mRNA sequencing and analysis workflow.

Whole brains of three groups of C57Bl/6 mice (n = 12) were processed and CD45+ve microglia were isolated via immunopanning. Microglia and CD45−ve bulk cell populations were sequenced for miRNA expression and analysed for differential expression using the edgeR/limma-voom pipeline. In addition, mRNA expression was sequenced in microglial populations and normalised read counts were correlated with miRNA data to construct miRNA–mRNA coregulatory networks.
