P2RY12 and Stroke: Microglial cluster expression profiles revealed a significant overlap between genes expressed in the homeostasis-associated microglial cluster 0 and published scRNA-Seq data from uninjured SVZ11, such as P2ry12, Tmem119, Cx3cr1, and HexB; as expected, gene expression in the stroke-associated clusters 1 and 4 did not overlap (Fig. 2f).
