Introduction: Microglial activation plays a crucial role in the pathology of ischemic stroke. Recently, we demonstrated that fingolimod (FTY720) exerted neuroprotective effects via immunomodulation in ischemic white matter damage induced by chronic cerebral hypoperfusion, which was accompanied by robust microglial activation. In this study, we assessed the pro-angiogenic potential of FTY720 in a murine model of acute cortical ischemic stroke. Methods: The photothrombotic (PT) method was used to induce cortical ischemic stroke in mice. We evaluated cortical damage, behavioral deficits, microglial polarization, and angiogenesis to identify the neuroprotective effects and possible molecular mechanisms of FTY720 in acute ischemic stroke. Results: In vivo, a reduction in neuronal loss and improved motor function were observed in FTY720-treated mice after PT stroke. Immunofluorescence staining revealed that robust microglial activation and the associated neuroinflammatory response in the peri-infarct area were ameliorated by FTY720 via its ability to polarize microglia toward the M2 phenotype. Furthermore, both in vivo and in vitro, angiogenesis was enhanced in the microglial M2 phenotype state. Behaviorally, a significant improvement in the FTY720-treated group compared to the control group was evident from days 7 to 14. Conclusions: Our research indicated that FTY720 treatment promoted angiogenesis via microglial M2 polarization and exerted neuroprotection in PT ischemic stroke.
