概括
与健康个体相比,银病患者的细胞外矩阵 (ECM) 碎片,如C4M,PRO-C3和PRO-C4在银病患者中升高. 然而,这些生物标志物在阿达利穆马布治疗后没有变化,这表明对监测牛皮治疗反应的效用有限.
科学领域:
- 生物化学 生化学
- 皮肤病学 皮肤病学
- 生物标志物发现发现
背景情况:
- 细胞外矩阵 (ECM) 碎片正在成为潜在的生物标志物.
- 之前的研究在脊椎关节炎和牛皮性关节炎中发现了ECM碎片.
- 它们在牛皮病和治疗反应中的作用需要进一步调查.
研究的目的:
- 为了调查特定的ECM碎片是否可以区分牛皮患者与健康对照.
- 评估这些ECM碎片作为治疗银病治疗反应的生物标志物的潜力.
主要方法:
- 从59名牛皮患者和52名健康对照人群中采集了血液样本 (EDTA血).
- 使用验证的ELISA和自动化化学发光试验量化了12个ECM碎片.
- 响应阿达利穆马布治疗的9名牛皮患者提供了随访样本.
主要成果:
- 与对照人群相比,在牛皮患者中观察到C4M (原IV降解),PRO-C3 (组织纤维化) 和PRO-C4 (表皮底膜周转) 的显著升高水平 (p=0.005,p=0.016,p=0.018).
- 即使在成功的治疗结果下,阿达利穆马布治疗也没有显著改变C4M,PRO-C3或PRO-C4.4的水平.
- 这些发现表明,虽然这些ECM碎片可以作为诊断指标,但它们对阿达利姆巴的治疗变化不敏感.
结论:
- 与健康个体相比,牛皮患者的C4M,PRO-C3和PRO-C4水平升高.
- 在响应者中,这些ECM片段似乎没有受到阿达利穆马布治疗的调节.
- 需要进一步的研究来探索ECM碎片作为牛皮的预测性或药理学生物标志物的实用性.

Overview
In order to maintain tissue organization, many animal cells are surrounded by structural molecules that make up the extracellular matrix (ECM). Together, the molecules in the ECM maintain the structural integrity of tissue as well as the remarkable specific properties of certain tissues.
Composition of the Extracellular Matrix
The extracellular matrix (ECM) is commonly composed of ground substance, a gel-like fluid, fibrous components, and many structurally and functionally diverse...

Unlike epithelial tissue, which is composed of cells closely packed with little or no extracellular space in between, connective tissue cells are dispersed in a matrix. This extracellular matrix (ECM) is composed of fibrous proteins like collagen, elastin, and fibronectin in a ground substance consisting of interstitial fluid, cell adhesion proteins, and proteoglycans. The proteoglycans form a gel-like material in the spaces between cells and provide hydration, buffering, binding, and force...
