Special Issue Information

Dear Colleagues,

Tuberculosis (TB) is the second leading infection killer after the current COVID-19 pandemic, and its causal agent is the bacilli Mycobacterium tuberculosis (Mtb). After exposure to Mtb, 5–10% of infected individuals develop active TB (ATB), and 90% develop a TB status called latent tuberculosis (LTB). The immune system of LTB patients controls the infection without eliminating Mtb.

TB patients display a chronic inflammation status. Mtb is an intracellular pathogen that mainly infects macrophages; however, it currently is well known that Mtb manipulates the host’s immune response to survive during the host’s life. Thus, the study of the immune response during TB is fundamental to the development of new therapies, vaccines, and diagnoses. 

Potential topics include but are not limited to the following:

  • Role of Monocytes/Macrophages during the pathogenic mycobacteria infection;
  • Immune responses during latent tuberculosis;
  • Immune response during active tuberculosis;
  • Cell death during the pathogenic mycobacteria infection;
  • Advances in diagnosis development to latent and active tuberculosis.

For this Special Issue, we cordially invite you to contribute with an article that provides new knowledge regarding the role of the immune response against Mtb. Research articles, reviews, case reports, and meta-analyses are welcome to be considered for publication after rigorous peer review.

Is there a CD4+ and CD8+ immunity alteration in patients with pulmonary tuberculosis (TB) and diabetes (DM) that does not recover after antituberculosis treatment? This prospective comparative study evaluated CD4+ and CD8+ lymphocytic subpopulations and antituberculosis antibodies in patients with diabetes and tuberculosis (TB-DM), before and after antituberculosis treatment. CD4+ T cell counts were lower in patients with TB-DM compared to those with only TB or only DM, and these levels remained low even after two months of anti-TB treatment. Regarding the CD8+ T cell analysis, we identified higher blood values in the DM-only group, which may be explained by the high prevalence of latent tuberculosis (LTBI) in patients with DM. IgM antituberculosis antibodies levels were elevated in patients with only TB at baseline, and 2 months post-anti-TB treatment, IgG did not express any relevant alterations. Our results suggest an alteration in CD4+ immunity in patients with TB-DM that did not normalize after antituberculosis treatment. Full article

Tuberculosis (TB) remains a public health problem worldwide and is one of the deadliest infectious diseases, only after the current COVID-19 pandemic. Despite significant advances in the TB field, there needs to be more immune response comprehension; for instance, the role played by humoral immunity is still controversial. This study aimed to identify the frequency and function of B1 and immature/transitional B cells in patients with active and latent TB (ATB and LTB, respectively). Here we show that LTB patients have an increased frequency of CD5+ B cells and decreased CD10+ B cells. Furthermore, LTB patients stimulated with mycobacteria’s antigens increase the frequency of IFN-γ-producing B cells, whereas cells from ATB do not respond. Moreover, under the mycobacterial protein stimulus, LTB promotes a pro-inflammatory environment characterized by a high level of IFN-γ but also can produce IL-10. Regarding the ATB group, they cannot produce IFN-γ, and mycobacterial lipids and proteins stimulate only the IL-10 production. Finally, our data showed that in ATB, but not in LTB, B cell subsets correlate with clinical and laboratory parameters, suggesting that these CD5+ and CD10+ B cell subpopulations have the potential to be biomarkers to differentiate between LTB and ATB. In conclusion, LTB has increased CD5+ B cells, and these cells can maintain a rich microenvironment of IFN-γ, IL-10, and IL-4. In contrast, ATB only maintains an anti-inflammatory environment when stimulated with mycobacterial proteins or lipids. Full article
