Immunity & ageing : I & A

|November 28, 2023

概括

炎症标志物,特别是那些表明先天免疫激活的标志物,与脆弱性有关. 这表明,与年龄相关的健康状况下降和累积的缺陷与可检测的轻度炎症有关.

科学领域:

老年学是一门学科.
免疫学免疫学免疫学
生物标志物生物标志物

背景情况:

脆弱性是一种与年龄相关的疾病,其特点是增加脆弱性和减少性.
衰老通常伴随着炎症,一种慢性低度炎症的状态.
现有的脆弱性评估包括问卷 (SF-36,EQ-5D-3L) 和脆弱性指数.

研究的目的:

调查29个循环炎症标志物与脆弱度量之间的关联.
探索连接衰老,炎症和脆弱的潜在机制.

主要方法:

一项前性队列研究在317名参与者 (年龄25-90岁) 中使用脆弱指数 (31个缺陷),EQ-5D-3L和SF-36物理域评估了脆弱性.
循环炎症标志物和病毒血清阳性 (CMV/EBV) 用Quanterix,Luminex和ELISA进行测量.
统计分析将炎症标志物与脆弱性指标相关联,调整为年龄和BMI.

主要成果:

这四种虚弱度都与年龄和BMI有很强的相关性.
19个生物标志物显示了与年龄相关的相关性,具有不同的模式 (线性,特定于年龄段,平稳).
经过年龄调整后,IL-6,CRP,IL-1RA,YKL-40和弹性酶显著与虚弱相关;BMI调整减少了这些关联.

结论:

循环的炎症标志物,特别是那些反映天生的免疫激活的标志物,与脆弱性有关.
这些发现支持了与年龄相关的健康下降,赤字积累和可检测的低级炎症之间的联系.
特定的炎症标志物可能表明伴随脆弱的炎症过程.

关键词:

Aging

Aging

Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers

Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...
