Tuberculosis (TB) has been the leading lethal infectious disease worldwide since 2014, and about one third of world's population latent TB infection (LTBI). It is largely attributed to difficulties in diagnosis treatment LTBI patients. Exosomes offer a new perspective on investigation process infection. In this study, we performed small RNA sequencing explore profiles serum exosomes derived from patients healthy controls (HC). Our results revealed distinct miRNA profile three groups. We...

The lack of effective differential diagnostic methods for active tuberculosis (TB) and latent infection (LTBI) is still an obstacle TB control. Furthermore, the molecular mechanism behind progression from LTBI to has been not elucidated. Therefore, we performed label-free quantitative proteomics identify plasma biomarkers discriminating pulmonary (PTB) LTBI. A total 31 overlapping proteins with significant difference in expression level were identified PTB patients (n = 15), compared...
