IL11 and ischemic stroke: In one of the pericytes clusters, the authors observed the upregulation of transcripts that we also identified in this study, such as Il11, Ednrb, Adamts4, Ccl2, and Il6. The authors describe that the pericytes belonging to this cluster highly expressed gene sets involved in immune functions after ischemic stroke, including Oncostatin-M-induced BBB breakdown, HIF-1, and cytokine-mediated signaling pathway.
