Abstract:

Mycobacterium tuberculosis (MTB) cell wall contains rich lipids, which helps to maintain its own virulence and the long-term latent in the host. Lipoarabinomannan (LAM) is an important component in the cell wall of MTB, and its complex and unique structure is crucial for the growth, survival and virulence of MTB. In this review, we summarized the structure, biosynthetic pathway of LAM and its role in immune response as well as its application value in tuberculosis diagnosis. It could provide a new vision and ideas for its potential as a new biomarker for tuberculosis diagnosis.
