背景情况:
- 补体系统是免疫调节和炎症的组成部分,与椎间盘退化 (IDD) 有关.
- 虽然已知变性磁盘的局部补充激活,但在变性磁盘疾病 (DDD) 血中系统补充表达尚不清楚.
研究的目的:
- 在患有退行性磁盘疾病 (DDD) 的患者的血中研究系统补充蛋白表达.
- 探索血补充蛋白作为DDD的血基生物标志物的潜力.
主要方法:
- 使用高通量质谱分析了40名DDD患者的血蛋白质组 (Modic变化和非Modic变化) 和20名健康志愿者.
- 分析了蛋白质组数据,以确定差异表达的补充蛋白,并评估与诸如C反应蛋白 (CRP) 等系统性炎症标记物的相关性.
主要成果:
- 蛋白质组分析在DDD患者和健康志愿者之间发现了血蛋白质概况的显著差异,补充和凝血级联的丰富.
- 大多数补充蛋白在DDD血中被上调,有显著的例外包括C1q复合体和补充因子D (CFD).
- 在DDD血中C-反应蛋白 (CRP) 水平升高表明系统性炎症,尽管血和组织补充水平之间的相关性很弱.

Regulated Protein Degradation
It is vital to regulate the activity of enzymatic as well as non-enzymatic proteins inside the cell. This can be achieved either through creating a balance between their rate of synthesis and degradation or regulating the intrinsic activity of the protein. Both these regulation mechanisms play an essential role in the normal functioning of cells.
Protein degradation plays two important roles in the cells. It helps to protect cells from misfolded or damaged proteins before they lead to a...

Degenerative Disc Disease I: Introduction
Degenerative disc disease is a chronic condition in which intervertebral discs gradually lose structure and function. It is not infectious or autoimmune; rather, it results from age-related biochemical and mechanical changes, influenced by genetic, metabolic, and environmental factors.Structure and Function of DiscsThe spine contains 23 intervertebral discs that absorb load, distribute forces, maintain spacing, and allow flexibility. Each disc consists of a nucleus pulposus, a gel-like core...
Degenerative Disc Disease ll: Pathophysiology
The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...
