研究目的:

通过比较原发性干燥综合征患者与对照组唾液腺免疫细胞转录组学特征,建立原发性干燥综合征唾液腺的免疫微环境图谱,进一步揭示该病的发病机制。了解导致原发性干燥综合征唾液腺功能障碍的关键致病因子,找到可用于该病诊断和治疗的生物学标志物。  

Objectives of Study:

By comparing the transcriptomic characteristics of salivary gland immune cells in patients with primary Sj?gren's syndrome and healthy controls, we aimed to establish an immune microenvironment landscape of the salivary glands of primary Sj?gren's syndrome to further reveal the pathogenesis of the disease. Second, we also aimed to identify key causative factors that cause salivary gland dysfunction in primary Sj?gren's syndrome and some biomarkers that can be used in the diagnosis and treatment of the disease.
