由于缺乏明确的生物标志物,早期诊断1型糖尿病 (T1D) 是一个挑战. 本综述探讨了古典和新兴的生物标志物,包括遗传和分子标志物,以改善早期T1D检测和风险评估.
科学领域:
- 免疫学 免疫学 免疫学
- 遗传学 遗传学 是一个
- 生物化学 生物化学
背景情况:
- 1型糖尿病 (T1D) 是一种自身免疫性疾病,导致胰腺β细胞的破坏,通常从童年开始.
- 目前T1D的诊断方法和生物标志物在早期检测和了解疾病机制方面存在局限性.
- 阴险的发病和缺乏明确的早期生物标志物阻碍了及时的诊断和预防策略.
研究的目的:
- 批判性地审查1型糖尿病 (T1D) 诊断的经典和新兴生物标志物.
- 评估生物标志物,使得T1D在显著的胰腺小岛破坏之前能够早期检测到.
- 识别当前T1D诊断中的差距,并指导未来研究的标记物选择.
主要方法:
- 对T1D生物标志物的现有文献的审查,包括遗传 (HLA-哈普类型,非HLA SNPs,GWAS,PRS),自身抗体,C-,细胞因子,cfDNA,microRNA,免疫细胞和TCRs.
- 探索新的方法,如单细胞转录组学和FTIR光谱学.
- 分析大规模研究中有希望的生物标志物的证据基础.
主要成果:
- 经典的生物标志物,如HLA-haplotype和自身抗体已经确立,但对早期预测有局限性.
- 新兴的生物标志物,如细胞因子,cfDNA,microRNA和特定的免疫细胞,对早期T1D检测有希望.
- 像GWAS,单细胞转录组学和FTIR光谱学等先进技术为T1D风险评估和诊断提供了新的途径.
结论:
- 虽然一些新的生物标志物仍处于研究阶段,但它们具有改善T1D诊断的巨大潜力.
- 将新兴生物标志物与经典标志物相结合,可以提高T1D早期和临床前检测的灵敏度和特异性.
- 需要进一步的研究来验证这些生物标志物,并开发T1D的全面诊断面板.

Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
