ABSTRACT
<p><b>OBJECTIVE</b>To investigate the efficacy of CD151 gene delivery in promoting blood perfusion in swines after myocardial infarction.</p><p><b>METHODS</b>Swines received coronary artery ligation and intramyocardial injection with rAAV-CD151, rAAV-anti-CD151 or rAAV-GFP. Eight weeks after vector injection, Western blot, immunostaining and 13N-labeled NH3 PET were performed to detect gene expression and biological effects of various treatments.</p><p><b>RESULTS</b>High level of CD151 protein expression was detected in the rAAV-CD151 group. The capillary density in the rAAV-CD151 group [(83.8 +/- 6.7) n/mm2] was significantly higher than that in the control group [(33.2 +/- 4.5) n/mm2] and rAAV-GFP group [(41.6 +/- 5.6) n/mm2] (all P<0.05); the arteriole density in the rAAV-CD151 group [(16.4 +/- 2.5) n/mm2] was also higher than that in the control group [(6.6 +/- 2.3) n/mm2] and the rAAV-GFP group [(8.4 +/- 1.6) n/mm2] (all P<0.05). However, the lowest capillary density and arteriole density were evidenced in rAAV-anti-CD151 group. Myocardial blood perfusion was significantly increased in rAAV-CD151 group and significantly reduced in rAAV-anti-CD151 group (all P<0.05 vs. control).</p><p><b>CONCLUSION</b>Intramyocardial injection of rAAV-CD151 could enhance the myocardial express of CD151 protein, increase capillary and arteriole densities and improve blood perfusion in swine with myocardial infarction.</p>
