摘要: 目的 探讨腺病毒载体介导Fas 配体(FasL) 基因导入对大鼠颈动脉损伤后血管中层平滑肌细胞密度的影响。方法 实验分治疗组(Ad-FasL 组) 和正常对照组两组(Ad-βgal 组), 每组动物均为6 只。利用重组腺病毒载体分别将Ad-FasL 、Ad-βgal 导入大鼠颈动脉球囊损伤的内膜, 3 、14 d 后观察其对血管中层平滑肌细胞密度的影响。结果 与正常对照组相比较, 通过腺病毒载体介导导入FasL 基因的被球囊损伤的大鼠颈动脉,3 d 后损伤血管中层平滑肌细胞密度降低, 14 d后血管中层平滑肌细胞密度恢复到正常水平。结论 FasL 可抑制血管中层平滑肌细胞密度, 从而抑制球囊损伤后的内膜增生。

Abstract: AIM: To investigate the effects of Fas ligand (FasL) gene transduction mediated by adenoviral vector on the density of medial layer vascular smooth muscle cell after rat carotid artery injury.METHODS: SD rats were divided into treatment group (Ad-FasL group) and normal control group(Ad-βgal group) (n=6).Ad-βgal, Ad-FasL gene were transduced into endomembrane of balloon injury of rat carotid artery using recombination adenovirus vector, the density of medial layer vascular smooth muscle cell was observed after 3, 14 days, respectively.RESULTS: Compared with the normal control group, the density of medial layer vascular smooth muscle cell decreased after injury for 3 days, and returned to normal levels after injury for 14 days.CONCLUSION: FasL gene transduction into the vessel wall could decrease the density of medial layer vascular smooth muscle cell and inhibit the endomembrane accrementition.
