概括
1型糖尿病 (T1D) 由于炎症而加速动脉样硬化. 在T1D患者中,细胞因子TGF-β1的较低水平与动脉厚度增加 (cIMT) 和血管功能降低 (FMD) 相相关.
科学领域:
- 心血管医学 心血管医学
- 内分泌学 在内分泌学.
- 免疫学 免疫学 免疫学
背景情况:
- 1型糖尿病 (T1D) 显著增加动脉样硬化风险,这是心血管事件的主要原因.
- 由风险因素驱动的通过炎症激活内皮细胞,启动动动脉硬化.
- 抗炎性细胞因子TGF-β1显示出抑制动脉样硬化发展的潜力.
研究的目的:
- 研究T1D患者TGF-β1水平和动脉样硬化标志物之间的关系.
- 为了比较T1D患者和健康对照者之间的动脉内膜介质厚度 (cIMT) 和流媒体扩张 (FMD).
- 评估TGF-β1与cIMT和T1D中的口炎的相关性.
主要方法:
- 这是一项涉及40名T1D患者和40名健康对照组 (平均年龄~14.6岁) 的横截面研究.
- 耳内心介质厚度 (cIMT) 通过心声回声学测量.
- 使用高分辨率超声波评估的流介导扩张 (FMD).
- 转化生长因子β1 (TGF-β1) 水平通过间接ELISA量化.
主要成果:
- 与对照组相比,T1D患者的cIMT (0.567比0.387毫米) 显著增加,口腔炎 (7.17比11.22毫米) 显著减少.
- 在T1D患者中,TGF-β1水平显著降低 (39.83比73.67ppg/ml).
- 在TGF-β1和cIMT之间发现了显著的负相关性 (r=-0.685),在TGF-β1和口之间发现了正相关性 (r=+0.55).
结论:

TGF - β Signaling Pathway
7.2K
The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...

Diabetes Mellitus: Type 2 and Gestational
2.1K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
