概括

水性幽默中的高温要求A (HTRA1) 水平与新血管与年龄相关的黄斑变性 (nAMD) 中的补体激活无关. 在nAMD患者中,HTRA1度不反映局部补充活性.

科学领域:

眼科医生眼科眼科
免疫学免疫学免疫学
遗传学是一个遗传学.

背景情况:

神经血管与年龄相关的黄斑变性 (nAMD) 是导致视力丧失的主要原因.
高温要求A (HTRA1) 和补充系统激活在nAMD病变发生中的作用尚未完全理解.

研究的目的:

研究HTRA1与nAMD中的局部补充系统之间的关系.
在nAMD患者的水性幽默中测量HTRA1和补充激活产品.

主要方法:

这是一项涉及121名nAMD患者和55名对照者的横截面研究.
测量水性幽默HTRA1,补充激活产品 (C3a,C4a) 和VEGF.
对ARMS2 A69S的基因定型,这是一种与HTRA1.1的链接不平衡的标志物.

主要成果:

与对照组相比,nAMD患者的HTRA1度在nAMD患者中较高.
在ARMS2 A69S基因型之间,HTRA1度没有显著差异.
在ARMS2风险等位基因 (T等位基因) 的眼睛中,VEGF和C3a度更高.
仅与VEGF度相关的HTRA1度.

结论:

在患有ARMS2风险等位基因的患者中,水性幽默中的HTRA1度没有升高.
HTRA1水平与补充激活产品C3a和C4a没有相关性.
水性幽默中的HTRA1水平似乎不反映nAMD的局部补充激活.

关键词:

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...
