研究目的: |
自身免疫性肝病(AILD)起病隐匿、致死率高,自身抗体是主要的血清学标志物。但是目前临床采用的检测技术以定性和半定量方法为主,现有AILD诊断方法存在方法学落后及灵敏度低等缺陷,难以实现AILD“早发现、早诊断、早治疗”。本项目通过可高度调控纳米材料合成技术及可编程的DNA walker和磁珠富集信号放大技术,设计构建可用于多靶标ANA、ASMA、抗-SLA、ANCA、抗-LKM和抗-LC1联合检测的生物传感系统,实现AILD高灵敏度定量评价,通过数学模型实现AILD精准评估。 |

Objectives of Study: |
Autoimmune Liver Disease (AILD) often presents insidiously with a high mortality rate. Autoantibodies serve as the primary serological markers for diagnosis. However, current clinical detection technologies predominantly rely on qualitative and semi-quantitative methods, which suffer from methodological limitations and low sensitivity, hindering the goal of "early detection, early diagnosis, and early treatment" for AILD. This project aims to address these challenges by leveraging highly tunable nanomaterial synthesis technology, programmable DNA walkers, and magnetic bead-based signal amplification strategies to design and construct a biosensing system capable of multiplex detection of key autoantibodies, including ANA, ASMA, anti-SLA, ANCA, anti-LKM, and anti-LC1. The system will enable high-sensitivity quantitative evaluation of AILD and further establish mathematical models to enable precise assessment of disease progression and severity. |
