Dengue Virus Type 2 Modulates Endothelial Barrier Function Through CD73

Dengue hemorrhagic fever is characterized by a unique vascular leakage syndrome. The mechanisms of endothelial barrier dysfunction in dengue hemorrhagic fever are not well understood. We examined the modulation of endothelial barrier function in dengue virus type 2 (DENV2) infections using primary human umbilical vein endothelial cells. We demonstrated that the increase in endothelial barrier function within 72 hours after DENV2 infection is mediated by type I interferon-dependent CD73 up-regulation. After 72 hours, DENV2 slowed the recovery of endothelial barrier function in response to tumor necrosis factor-α or vascular endothelial growth factor. This phenomenon was likely caused by type I interferon receptor signaling inhibition and lower CD73 levels in DENV2-infected endothelial cells. Our findings suggest that during DENV2 infection, endothelial barrier homeostasis is maintained by a balance between pro-inflammatory and pro-angiogenic cytokines, and type I interferon-dependent CD73 expression and activity.
