Abstract
Tuberculosis remains a major health threat globally and a more effective vaccine than the current Bacillus Calmette Guerin (BCG) is required, either to replace or boost it. The Spore-FP1 mucosal vaccine candidate is based on the fusion protein of Ag85B-Acr-HBHA/heparin-binding domain, adsorbed on the surface of inactivated Bacillus subtilis spores. The candidate conferred significant protection against Mycobacterium. tuberculosis challenge in naïve guinea pigs and markedly improved protection in the lungs and spleens of animals primed with BCG. We then immunized rhesus macaques with BCG intradermally, and subsequently boosted with one intradermal and one aerosol dose of Spore-FP1, prior to challenge with low dose aerosolized M. tuberculosis Erdman strain. Following vaccination, animals did not show any adverse reactions and displayed higher antigen specific cellular and antibody immune responses compared to BCG alone but this did not translate into significant improvement in disease pathology or bacterial burden in the organs.

Abstract
Specific T cell responses are central for protection against infection with M. tuberculosis. Here we show that mycobacteria-specific CD4 and CD8 T cells accumulated in the lung but not in the mediastinal lymph node (MLN) at different time points after M. tuberculosis infection or BCG immunization. Proliferating specific T cells were found in the lung after infection and immunization. Pulmonary, but not MLN-derived CD4 and CD8 T cells, from M. tuberculosis-infected mice secreted IFN-γ after stimulation with different mycobacterial peptides. Mycobacteria-specific resident memory CD4 and CD8 T cells (TRM) expressing PD-1 accumulated in the lung after aerosol infection and intratracheal (i.t.) -but not subcutaneous (s.c.)- BCG immunization. Chemical inhibition of recirculation indicated that TRM were generated in the lung after BCG i.t. immunization. In summary, mycobacteria specific-TRM accumulate in the lung during i.t. but not s.c. immunization or M. tuberculosis infection. Collectively our data suggests that priming, accumulation and/or expansion of specific T cells during BCG immunization and M. tuberculosis infection occurs in the lung.

Abstract
We have reported previously that T cells from patients with multi-drug-resistant tuberculosis (MDR-TB) express high levels of interleukin (IL)-17 in response to the MDR strain M (Haarlem family) of Mycobacterium tuberculosis (M. tuberculosis). Herein, we explore the pathways involved in the induction of Th17 cells in MDR-TB patients and healthy tuberculin reactors [purified protein derivative healthy donors (PPD+ HD)] by the M strain and the laboratory strain H37Rv. Our results show that IL-1β and IL-6 are crucial for the H37Rv and M-induced expansion of IL-17+ interferon (IFN)-γ- and IL-17+ IFN-γ+ in CD4+ T cells from MDR-TB and PPD+ HD. IL-23 plays an ambiguous role in T helper type 1 (Th1) and Th17 profiles: alone, IL-23 is responsible for M. tuberculosis-induced IL-17 and IFN-γ expression in CD4+ T cells from PPD+ HD whereas, together with transforming growth factor (TGF-β), it promotes IL-17+ IFN-γ- expansion in MDR-TB. In fact, spontaneous and M. tuberculosis-induced TGF-β secretion is increased in cells from MDR-TB, the M strain being the highest inducer. Interestingly, Toll-like receptor (TLR)-2 signalling mediates the expansion of IL-17+ IFN-γ- cells and the enhancement of latency-associated protein (LAP) expression in CD14+ and CD4+ T cells from MDR-TB, which suggests that the M strain promotes IL-17+ IFN-γ- T cells through a strong TLR-2-dependent TGF-β production by antigen-presenting cells and CD4+ T cells. Finally, CD4+ T cells from MDR-TB patients infected with MDR Haarlem strains show higher IL-17+ IFN-γ- and lower IL-17+ IFN-γ+ levels than LAM-infected patients. The present findings deepen our understanding of the role of IL-17 in MDR-TB and highlight the influence of the genetic background of the infecting M. tuberculosis strain on the ex-vivo Th17 response.

Abstract
Tuberculous pleural effusion is characterized by a T helper type 1 (Th1) profile, but an excessive Th1 response may also cause tissue damage that might be controlled by regulatory mechanisms. In the current study we investigated the role of regulatory T cells (Treg ) in the modulation of Th1 responses in patients with tuberculous (TB) pleurisy. Using flow cytometry we evaluated the proportion of Treg (CD4(+) CD25(high) forkhead box protein 3(+) ), interferon (IFN)-γ and interleukin (IL)-10 expression and CD107 degranulation in peripheral blood (PB) and pleural fluid (PF) from patients with TB pleurisy. We demonstrated that the proportion of CD4(+) CD25(+) , CD4(+) CD25(high) FoxP3(+) and CD8(+) CD25(+) cells were increased in PF compared to PB samples. Mycobacterium tuberculosis stimulation increased the proportion of CD4(+) CD25(low/neg) IL-10(+) in PB and CD4(+) CD25(low/neg) IFN-γ(+) in PF; meanwhile, CD25(high) mainly expressed IL-10 in both compartments. A high proportion of CD4(+) CD107(+) and CD8(+) CD107(+) cells was observed in PF. Treg depletion enhanced the in-vitro M. tuberculosis-induced IFN-γ and CD4(+) and CD8(+) degranulation responses and decreased CD4(+) IL-10(+) cells in PF. Our results demonstrated that in TB pleurisy Treg cells effectively inhibit not only IFN-γ expression but also the ability of CD4(+) and CD8(+) cells to degranulate in response to M. tuberculosis.

Abstract
Tuberculosis (TB) is one of the world's most pernicious diseases mainly due to immune evasion strategies displayed by its causative agent Mycobacterium tuberculosis (Mtb). Blood monocytes (Mos) represent an important source of DCs during chronic infections; consequently, the alteration of their differentiation constitutes an escape mechanism leading to mycobacterial persistence. We evaluated whether the CD16(+)/CD16(-) Mo ratio could be associated with the impaired Mo differentiation into DCs found in TB patients. The phenotype and ability to stimulate Mtb-specific memory clones DCs from isolated Mo subsets were assessed. We found that CD16(-) Mos differentiated into CD1a(+) DC-SIGN(high) cells achieving an efficient recall response, while CD16(+) Mos differentiated into a CD1a(-) DC-SIGN(low) population characterized by a poor mycobacterial Ag-presenting capacity. The high and sustained phosphorylated p38 expression observed in CD16(+) Mos was involved in the altered DC profile given that its blockage restored DC phenotype and its activation impaired CD16(-) Mo differentiation. Furthermore, depletion of CD16(+) Mos indeed improved the differentiation of Mos from TB patients toward CD1a(+) DC-SIGN(high) DCs. Therefore, Mos from TB patients are less prone to differentiate into DCs due to their increased proportion of CD16(+) Mos, suggesting that during Mtb infection Mo subsets may have different fates after entering the lungs.

Abstract
Bacillus thuringiensis is classified into serovars on the basis of H-flagellar antigens. Several alternative typing methods have been described. Among them, a B. cereus group-specific repetitive extragenic palindromic (Rep)-PCR fingerprinting technique was shown to be discriminative and able to identify B. thuringiensis serovars. The aim of this study was to investigate the genomic diversity and relationship among B. thuringiensis strains collected from different Argentinean ecosystems. Thirty-seven B. thuringiensis reference strains and 131 Argentinean isolates were analyzed using a B. cereus group-specific Rep-PCR. Fourteen different patterns were identified among the Argentinean isolates. Eight could not be associated to any pattern obtained from a reference strain. The pattern identical to the serovar kurstaki HD-1 strain was the most frequently identified in 68 native isolates. The profiles allowed tracing a single dendrogram with two groups and eight main lineages. Some strains showed distinctive patterns despite belonging to the same serovar. An intraspecific diversity resulted from this analysis that was highlighted by this technique since strains from a given serovar showed distinct profiles. This study may help to establish a system of B. thuringiensis classification with a higher discrimination level than established by the H antigen serotyping.

Abstract
BACKGROUND The proinflammatory cytokine interleukin 17 (IL-17) plays an important role in immune responses but it is also associated with tissue-damaging inflammation. So, we evaluated the ability of Mycobacterium tuberculosis clinical isolates to induce IL-17 in tuberculosis (TB) patients and in healthy human tuberculin reactors (PPD(+)HD). METHODS IL-17, interferon γ (IFN-γ), and interleukin 23 (IL-23) receptor expression were evaluated ex vivo and cultured peripheral blood mononuclear cells from TB and PPD(+)HD stimulated with irradiated clinical isolates from multidrug resistant (MDR) outbreaks M (Haarlem family) and Ra (Latin American-Mediterranean family), as well as drug-susceptible isolates belonging to the same families and laboratory strain H37Rv for 48 hours in T-cell subsets by flow cytometry. RESULTS We observed that: (1) MDR strains M and Ra are stronger IL-17 inducers than drug-susceptible Mtb strains of the Haarlem and Latin American-Mediterranean families, (2) MDR-TB patients show the highest IL-17 expression that is independent on the strain, (3) IL-17 expression is dependent on CD4(+) and CD8(+) T cells associates with persistently high antigen load. CONCLUSIONS IL-17--producing T cells could play an immunopathological role in MDR-TB promoting severe tissue damage, which may be associated with the low effectiveness of the second-line drugs employed in the treatment.
