Background-Renarrowing of dilated arterial sites (restenosis) hampers the clinical benefits of coronary angioplasty. Infiltration and activation of monocytes in, the arterial wall mediated by monocyte chemoattractant protein-1 (MCP-1) might be a major cause of restenosis after angioplasty. However, there is no direct evidence to support a definite role of MCP-1 in the development of restenosis.Methods and Results-We recently devised a new strategy for anti-MCP-1 gene therapy by transfecting an N-terminal deletion. mutant of the MCP-1 gene into skeletal muscles. We used this strategy to investigate the role of MCP-1 in the development of restenotic changes after balloon injury in the carotid artery in hypercholesterolemic rabbits. Intramuscular transfection of the mutant MCP-1 gene suppressed monocyte infiltration/activation in the injured arterial wall and thus attenuated the development of neointimal hyperplasia and negative remodeling.Conclusions-MCP-1-mediated monocyte infiltration is necessary in the development of restenotic changes to balloon injury in hypercholesterolemic rabbits. This strategy may be a useful and practical form of gene therapy against human restenosis.
