概括

在外围动脉疾病模型中,金属蛋白酶ADAMTS13对于恢复血液流动并非至关重要. 在患有后肢缺血的小鼠中,ADAMTS13缺乏并没有阻碍血管生成或动脉生成.

科学领域:

血管生物学血管生物学
心血管研究的心血管研究.
动脉样硬化是一种动脉样硬化.

背景情况:

周围动脉疾病 (PAD) 由动脉样硬化引起,导致慢性缺血症.
动脉生成和血管生成是恢复血液流动的关键机制.
金属蛋白酶ADAMTS13在缺血血管重塑中的作用尚不清楚.

研究的目的:

研究ADAMTS13在缺血引起的动脉发生和血管发生中的作用.
用后肢缺血模型比较ADAMTS13缺乏和野生型小鼠的血管改造.

主要方法:

小鼠后肢缺血模型.
激光多普勒测量用于 perfusion 恢复.
免疫组织化学用于细胞增殖和透.
在体内显微镜检测血栓活性.

主要成果:

缺乏ADAMTS13并没有影响 perfusion 恢复,附带动脉生长或毛细血管形成.
血小板粘附量略有增加,但没有发生血栓塞.
炎症反应 (巨/中性粒细胞透,极化) 没有受到影响.
缺少ADAMTS13并没有影响体内血管生成.

结论:

在无菌条件下,ADAMTS13对与缺血相关的血管新生和动脉新生无关紧要.
ADAMTS13可能只适用于严重的血栓炎症.

Regulation of Angiogenesis and Blood Supply

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Mechanism of Angiogenesis

Mechanism of Angiogenesis

Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...
