In the present study, we determined the effect of circulating endothelial cell-derived microvesicles (EMVs) isolated from e-cigarette users on human cerebral microvascular endothelial cells (hCMECs) nitric oxide (NO) and endothelin (ET)-1 production and tissue-type plasminogen activator (t-PA) release. EMVs from e-cigarette users reduced brain microvascular endothelial cell NO production, enhanced ET-1 production, and impaired endothelial t-PA release. EMVs are a potential mediating factor in the increased risk of stroke associated with e-cigarette use.
