研究目的: |
本研究以系统性红斑狼疮(SLE)情绪障碍的发病机制为切入点,旨在明确5-HTTLPR基因多态性通过杏仁核结构和功能改变影响SLE情绪障碍的作用机制,并为SLE情绪障碍的早期识别与精准干预提供理论依据。具体目的包括: (1)明确SLE患者5-HTTLPR基因多态性与情绪障碍(焦虑、抑郁)及免疫炎症紊乱的相关性,从遗传-免疫交互角度阐明SLE情绪障碍的易感机制; (2)利用多模态磁共振成像技术,系统评估伴与不伴情绪障碍的SLE患者杏仁核亚区体积、微结构完整性及功能连接的改变特征,明确杏仁核亚区损伤在SLE情绪障碍中的神经病理基础; (3)通过构建中介效应模型,验证5-HTTLPR基因多态性是否通过杏仁核亚区结构及功能损害的介导途径导致SLE情绪障碍,并量化该中介效应,从而整合遗传、影像与免疫多维度证据,揭示SLE情绪障碍的潜在因果通路。最终,本研究期望发现可用于早期识别SLE情绪障碍的影像-遗传联合标志物,并为开发靶向神经-免疫交互通路的诊疗策略提供新思路。 |

Objectives of Study: |
This study aims to elucidate how 5-HTTLPR gene polymorphism affects mood disorders in systemic lupus erythematosus (SLE) through amygdala structural and functional alterations, providing a theoretical basis for early identification and targeted intervention. Specifically: (1) To determine the association between 5-HTTLPR polymorphism and mood disorders (anxiety/depression) as well as immune-inflammatory dysregulation in SLE patients; (2) To characterize amygdala subregional volumetric, microstructural, and functional connectivity changes in SLE patients with versus without mood disorders using multimodal MRI; (3) To verify and quantify the mediating role of amygdala subregional damage in the pathway from 5-HTTLPR polymorphism to SLE mood disorders through mediation analysis, thereby integrating genetic, neuroimaging, and immunological evidence to reveal the underlying neuro-immune mechanisms.Ultimately, this study seeks to identify potential imaging-genetic biomarkers for early recognition of SLE mood disorders and to inform novel therapeutic strategies targeting neuro-immune pathways. |
