scRNA-seq identified of a unique LILRB4+ microglia subtype associated with stroke. (A) Spatial transcriptomics analysis of LILRB4 expression in the ischemic hemisphere in mice after stroke. (B) t-SNE plots showing the disease origin and the distribution of microglia. (C) Histograms of subcellular components in the control and deletion groups. (D) The t-SNE diagram showing that LILRB4 is expressed mainly in MG3. (E) Violin plot depicting the LILRB4 expression profile of microglia subtypes. (F) Heatmap of differentially expressed genes between LILRB4+ microglia subtype and WT steady state microglia. (G) Selected significantly enriched pathways by gene set enrichment analysis between LILRB4+ microglia and WT subtype
