Tuberculosis (TB) caused by Mycobacterium tuberculosis remains a deadly infectious disease. The thin pipeline of new drugs for TB, the ineffectiveness in adults of the only vaccine available, i.e. the Bacillus Calmette-Guerin vaccine, and increasing global antimicrobial resistance, has reinvigorated interest in immunotherapies. Nanoparticles (NPs) potentiate the effect of immune modulating compounds (IMC), enabling cell targeting, improved transfection of antigens, enhanced compound stability and provide opportunities for synergistic action, via delivery of multiple IMCs. In this review we describe work performed in the application of NPs towards achieving immune modulation for TB treatment and vaccination. Firstly, we present a comprehensive review of M. tuberculosis and how the bacterium modulates the host immune system. We find that current work suggest great promise of NP based immunotherapeutics as novel treatments and vaccination systems. There is need to intensify research efforts in this field, and rationally design novel NP immunotherapeutics based on current knowledge of the mycobacteriology and immune escape mechanisms employed by M. tuberculosis.

Aims: Mycobacterium tuberculosis (Mtb) remains a major global health challenge, particularly due to increasing drug resistance. Beyond the well-characterized mutations, the mechanisms involved in driving resistance appear to be more complex. This study investigated the differential gene expression of Ethiopian drug-resistant Mtb sub-lineage 4.

In the current medical era, the proliferation and dissemination of drug-resistant strains of Mycobacterium tuberculosis continue to pose a significant worldwide health hazard, necessitating the development of new and innovative medications to combat tuberculosis. Decaprenylphosphoryl-β-D-ribose 2'-epimerase (DprE1) is a crucial enzyme for cell wall synthesis in Mycobacterium tuberculosis (Mtb). Its importance is due to its eminent contribution in forming lipoarabinomannan and arabinogalactan.

Alveolar macrophages (AMs) are lung-resident myeloid cells and airway sentinels for inhaled pathogens and environmental particles. While AMs can be highly inflammatory in response to respiratory viruses, they do not mount proinflammatory responses to all airborne pathogens. For example, we previously showed that AMs fail to mount a robust proinflammatory response to Mycobacterium tuberculosis.
