严重肢体缺血是外周动脉疾病的一种破坏性表现,没有有效的策略来改善发病率和死亡率结果。我们测试了细胞线粒体功能是肢体病理学的关键组成部分的假设,改善线粒体功能代表了一种新的治疗模式。BALB/c小鼠用治疗性脑靶向肽(MTP-131)处理并经受肢体缺血(HLI)。与媒介物对照相比,MTP-131挽救了肢体肌肉毛细血管密度和血流量(对侧的64.7 ± 11%对39.9 ± 4%),并改善了肌肉再生。在HLI第7天,MTP-131还增加了所有条件下的电子传递系统通量。在体外,暴露于实验性缺血的原代肌细胞表现出显著降低(约75%)的细胞呼吸,这在恢复期被MTP-131挽救。与肌细胞相比,内皮细胞(HUVEC)呼吸固有地保护缺血(约30%减少),但也被MTP-131增强。这些研究结果表明缺血组织生物能量学和肢体血流之间的重要联系,并表明线粒体可能是一个药物治疗干预在严重的肢体缺血。
Critical limb ischemia is a devastating manifestation of peripheral arterial disease with no effective strategies for improving morbidity and mortality outcomes. We tested the hypothesis that cellular mitochondrial function is a key component of limb pathology and that improving mitochondrial function represents a novel paradigm for therapy. BALB/c mice were treated with a therapeutic mitochondrial-targeting peptide (MTP-131) and subjected to limb ischemia (HLI). Compared to vehicle control, MTP-131 rescued limb muscle capillary density and blood flow (64.7 ± 11% of contralateral vs. 39.9 ± 4%), and improved muscle regeneration. MTP-131 also increased electron transport system flux across all conditions at HLI day-7. In vitro, primary muscle cells exposed to experimental ischemia demonstrated markedly reduced (~ 75%) cellular respiration, which was rescued by MTP-131 during a recovery period. Compared to muscle cells, endothelial cell (HUVEC) respiration was inherently protected from ischemia (~ 30% reduction), but was also enhanced by MTP-131. These findings demonstrate an important link between ischemic tissue bioenergetics and limb blood flow and indicate that the mitochondria may be a pharmaceutical target for therapeutic intervention during critical limb ischemia.
