概括
糖尿病外围神经病变 (DPN) 与明显的角膜树突细胞 (DC) 模式有关. 在DPN患者中,不成熟的DC积聚在神经之外,而成熟的DC则在疼痛的DPN中在神经附近减少,这表明糖尿病神经病变中免疫参与.
科学领域:
- 眼科医生 眼科 眼科
- 免疫学 免疫学 免疫学
- 神经学 神经学
背景情况:
- 角膜树突细胞 (DCs) 是反映系统性炎症的免疫细胞.
- 调查角膜DC模式可能为糖尿病及其并发症提供见解.
研究的目的:
- 探索角膜DC密度和成熟度与糖尿病,糖尿病外围神经病变 (DPN) 和神经病痛之间的关联.
- 为了在疼痛的DPN,无痛的DPN,没有DPN的糖尿病和健康的对照中区分DC配置文件.
主要方法:
- 用角膜共聚焦显微镜量化和分类DCs (成熟/不成熟) 以及它们与角膜神经的接近.
- 参与者包括1型糖尿病 (T1DM) 和疼痛的DPN (n=19),T1DM和无痛的DPN (n=15),没有DPN的T1DM (n=19) 和健康的对照 (n=20) 的个人.
主要成果:
- 两组之间没有发现DC总密度的显著差异.
- 与没有DPN的人相比,患有DPN (疼痛或无痛) 的人显示出远离角膜神经的不成熟DCs增加.
- 与其他组相比,疼痛DPN与角膜神经附近成熟DCs的密度较低有关.
结论:
- 明显的角膜直流分布模式与疼痛和无疼痛的DPN相关.
- 研究结果表明,糖尿病神经病变和神经病痛的发展中可能存在免疫媒介机制.
- 需要进一步的研究来澄清这些观察的病理生理学意义.

Nociception
33.0K
Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain.

Local Anesthetics: Differential Sensitivity of Nerve Fibers
1.3K
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...

Psychoneuroimmunology: Diabetes and Cancer

Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...
