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
