C(6)-Ceramide-Coated Catheters Promote Re-Endothelialization of Stretch-Injured Arteries.

OBJECTIVE: Drug eluting stents have recently been associated with the increased risk of adverse thrombogenic events and/or late luminal loss, which is highly associated with incomplete re-endothelialization. The increased risks behoove the design of alternative delivery modalities and/or drugs that do not compromise the re-endotheliaization process. The objective of the present study is to elucidate the biological mechanism(s) by which non-stent-based delivery modalities for the anti-proliferative lipid metabolite, C(6)-ceramide, could lead to a reduction in arterial injury after angioplasty.
