概括

唾液的代谢变化可以区分Sjögren综合征 (SS) 患者与健康个体. 这项研究确定了与氧化应激和SS唾液中T细胞激活相关的关键代谢物.

科学领域:

免疫学免疫学免疫学
代谢学代谢学代谢学
自免疫性疾病自免疫性疾病

背景情况:

肖格伦综合征 (Sjögren's Syndrome,简称SS) 是一种慢性自身免疫性疾病,影响外分泌腺.
代谢变化与自身免疫性疾病有关,但它们在SS中的作用未得到充分研究.
唾液腺是SS的主要目标,使其成为代谢研究的重点.

研究的目的:

研究SS患者的唾液腺微环境中的代谢变化.
利用有针对性的代谢学方法来识别与SS.相关的特定代谢概况.
探索唾液代谢物作为SS.生物标志物的潜力.

主要方法:

从10名SS患者和10名健康志愿者收集了唾液样本.
超高性能液态染色学合质谱法 (UPLC-MS) 用于代谢分析.
使用有针对性的代谢学方法来分析特定的代谢物.

主要成果:

在SS患者中观察到乳酸盐,氨酸和酸盐的水平增加,表明氧化应激升高.
较高度的阿尔金因,白氨酸,氨酸和异氨酸表明增强的T细胞生长和扩散在SS.
在唾液样本中,在SS患者和健康对照人群之间确定了不同的代谢概况.

结论:

唾液代谢学可以将SS患者与健康个体区分开来.
唾液代谢概况可能反映了SS中受损的唾液腺体内的细胞变化.
这种方法为SS诊断和了解疾病机制提供了潜在的非侵入性方法.

Salivary Glands and Saliva

Salivary Glands and Saliva

The salivary glands, of which there are three pairs known as the parotid, submandibular, and sublingual glands, play a crucial role in maintaining oral health and initiating the digestive process. Positioned near the ears, beneath the masseter muscle, the parotid glands secrete saliva into the oral cavity through the parotid duct of Stensen. Meanwhile, the submandibular glands, located on the floor of the mouth, secrete saliva through channels named submandibular ducts. The sublingual glands,...
