研究目的:

主要目的:本项目拟首次展开临床诊断试验明确Aβ34作为AD早期诊断的血液标志物的可行性,明确Aβ34试剂盒的敏感性和特异性。旨在通过促进AD的敏感特异外周体液生物标志物的研究,推动AD的主动筛查和主动干预。本项目成功完成后将在国内外首次明确Aβ34作为AD早期诊断具有高度敏感性和特异性的血液标志物的可行性,对推动AD临床诊疗的精准化、促进AD的早期诊疗具有重要意义。 次要目的:我们拟基于项目组自主研发的Aβ34单克隆抗体和相应的试剂盒,进一步研发基于血浆Aβ34的超敏检测试剂盒,并建立基于血浆Aβ34的AD早期诊断和监测体系,具有广泛的临床应用前景。我们拟进一步建立基于Aβ34代谢调控关键靶点的AD早期干预策略,并研发一系列AD治疗药物,造福广大AD患者,可产生显著的社会效益和经济效。  

Objectives of Study:

Main Purpose This project intends to conduct a clinical diagnostic trial for the first time to verify the feasibility of Aβ34 as a blood biomarker for the early diagnosis of Alzheimer's disease (AD), and to determine the sensitivity and specificity of the Aβ34 detection kit. By advancing research on sensitive and specific peripheral fluid biomarkers for AD, it aims to promote active screening and proactive intervention of the disease. Upon successful completion, this project will be the first at home and abroad to confirm the feasibility of Aβ34 as a blood biomarker with high sensitivity and specificity for the early diagnosis of AD, which is of great significance for promoting the precision of clinical diagnosis and treatment of AD and facilitating its early detection and intervention. Secondary Purpose Based on the independently developed Aβ34 monoclonal antibody and corresponding kit by the research team, we plan to further develop an ultrasensitive plasma Aβ34 detection kit and establish an AD early diagnosis and monitoring system based on plasma Aβ34, which has broad clinical application prospects. In addition, we aim to further formulate early intervention strategies for AD targeting key nodes in Aβ34 metabolic regulation and develop a series of therapeutic drugs for AD to benefit numerous AD patients, thereby generating remarkable social and economic benefits.
