摘要:

结核病是由结核分枝杆菌复合群引发的人畜共患病,甘露糖帽修饰的脂阿拉伯甘露聚糖(mannose-capped-lipoarabinomannan,ManLAM)是结核分枝杆菌细胞壁上重要的成分,具有免疫调节作用,能够被固有细胞和适应性细胞所识别。作为结核病诊断的生物标记物,存在于体液的ManLAM具有较好的特异性,有区分结核分枝杆菌潜伏感染和活动性结核病的潜力,对于不能获取痰液的结核病患者也具有一定的检测价值。笔者系统介绍ManLAM的结构、生物合成及ManLAM的相关抗体等,并对其在结核病诊断中的研究进展进行总结,以期为结核病诊断技术的研发提供参考。

Abstract:

Tuberculosis is a significant zoonosis caused by Mycobacterium tuberculosis complex. Mannose-capped-lipoarabinomannan (ManLAM), an essential glycolipid component of the cell wall, has immunomodulatory effects and is recognized by intrinsic cells and adaptive cells. ManLAM in body fluids is a biomarker with good specificity for the diagnosis of tuberculosis, and has the potential ability to differentiate the latent tuberculosis infection and active tuberculosis. It also plays a certain role in detecting tuberculosis patients whose sputum could not be obtained. This article mainly introduces the structure, biosynthesis, and the related antibodies of ManLAM and summarizes the research progress in the diagnosis of tuberculosis, in order to provide reference for the development of tuberculosis diagnostic technology.

Key words: Mannans, Mycobacterium tuberculosis, Diagnosis, Review literature as topic
