| Outline of Final Research Achievements |
The asymptomatic group, which is called latent infection of Mycobacterium tuberculosis (LITB), is recognized as vitally important in controlling TB, because a majority of cases develop from latent infections. Thus, it has been required new diagnostic method to exactly establish LTBI. In this study, we examined the biomarker-targeted protein into macrophage-derived exosomes. After infection with active or latent Mycobacterium bovis Bacillus Calmette-Guerin, the expressions of both inflammatory and uninflammatory factor were up-regulated in RAW264.7 macrophages. Therefore, the protein were increased in exosomes from BCG-infected macrophages (BCG-exo) compared with exosomes from uninfected macrophages (none-exo). Moreover, it was identified 9 proteins, which is in BCG-exo derived from BCG-infected macrophages.
