CD40L-CD40 interactions regulate endothelial cell surface tissue factor and thrombomodulin expression

Abstract excerpt

During immune responses, activated endothelial cells down-regulate thrombomodulin and up-regulate tissue factor expression leading to the development of a procoagulant surface. CD4+ T cells are known to promote endothelial cell procoagulant activity, however, the molecular interactions that mediate this effect are not completely known. CD40L is an activation-induced CD4+ T cell surface molecule that functionally...
