Dual RNA-Seq of Human Leprosy Lesions Identifies Bacterial Determinants Linked to Host Immune Response. Cell Rep 2019; 26:3574-3585.e3.

Abstract
To understand how the interaction between an intracellular bacterium and the host immune system contributes to outcome at the site of infection, we studied leprosy, a disease that forms a clinical spectrum, in which progressive infection by the intracellular bacterium Mycobacterium leprae is characterized by the production of type I IFNs and antibody production. Dual RNA-seq on patient lesions identifies two independent molecular measures of M. leprae, each of which correlates with distinct aspects of the host immune response. The fraction of bacterial transcripts, reflecting bacterial burden, correlates with a host type I IFN gene signature, known to inhibit antimicrobial responses. Second, the bacterial mRNA:rRNA ratio, reflecting bacterial viability, links bacterial heat shock proteins with the BAFF-BCMA host antibody response pathway. Our findings provide a platform for the interrogation of host and pathogen transcriptomes at the site of infection, allowing insight into mechanisms of inflammation in human disease.

Abstract
Even after decades searching for a new and more effective vaccine against tuberculosis, the scientific community is still pursuing this goal due to the complexity of its causative agent, Mycobacterium tuberculosis (Mtb). Mtb is a microorganism with a robust variety of survival mechanisms that allow it to remain in the host for years. The structure and nature of the Mtb envelope play a leading role in its resistance and survival. Mtb has a perfect machinery that allows it to modulate the immune response in its favor and to adapt to the host's environmental conditions in order to remain alive until the moment to reactivate its normal growing state. Mtb cell envelope protein, carbohydrate and lipid components have been the subject of interest for developing new vaccines because most of them are responsible for the pathogenicity and virulence of the bacteria. Many indirect evidences, mainly derived from the use of monoclonal antibodies, support the potential protective role of Mtb envelope components. Subunit and DNA vaccines, lipid extracts, liposomes and membrane vesicle formulations are some examples of technologies used, with encouraging results, to evaluate the potential of these antigens in the protective response against Mtb.

Abstract
Despite worldwide availability of the vaccines against most of the infectious diseases, BCG and various programs such as Directly Observed Treatment Short course (DOTS) to prevent tuberculosis still remains one of the most deadly forms of the disease affecting millions of people globally. The evolution of multi drug resistant strains (MDR) has increased the complexity further. Although currently available marketed BCG vaccine has shown sufficient protection against childhood tuberculosis, it has failed to prevent the most common form of disease i.e., pulmonary tuberculosis in adults. However, various vaccine candidates have already entered phase I clinical trials and have shown promising outcomes. The most prominent amongst them is the heterologous prime-boost approach, which shows a great promise towards designing and development of a new efficacious tuberculosis vaccine. It has also been shown that the use of various viral and non-viral vectors as carriers for the potential vaccine candidates will further boost their effect on subsequent immunization. In this review, we briefly summarize the potential of a few novel nano-carriers for developing effective vaccination strategies against tuberculosis.

Abstract
Vaccines were initially developed on an empirical basis, relying mostly on attenuation or inactivation of pathogens. Advances in immunology, molecular biology, biochemistry, genomics, and proteomics have added new perspectives to the vaccinology field. The use of recombinant proteins allows the targeting of immune responses focused against few protective antigens. There are a variety of expression systems with different advantages, allowing the production of large quantities of proteins depending on the required characteristics. Live recombinant bacteria or viral vectors effectively stimulate the immune system as in natural infections and have intrinsic adjuvant properties. DNA vaccines, which consist of non-replicating plasmids, can induce strong long-term cellular immune responses. Prime-boost strategies combine different antigen delivery systems to broaden the immune response. In general, all of these strategies have shown advantages and disadvantages, and their use will depend on the knowledge of the mechanisms of infection of the target pathogen and of the immune response required for protection. In this review, we discuss some of the major breakthroughs that have been achieved using recombinant vaccine technologies, as well as new approaches and strategies for vaccine development, including potential shortcomings and risks.

Abstract
Considering that mycobacterial heat-shock protein 65 (hsp65) gene transfer can elicit a profound antitumoral effect, this study aimed to establish the safety, maximum-tolerated dose (MTD) and preliminary efficacy of DNA-hsp65 immunotherapy in patients with advanced head and neck squamous cell carcinoma (HNSCC). For this purpose, 21 patients with unresectable and recurrent HNSCC were studied. Each patient received three ultrasound-guided injections at 21-day intervals of: 150, 600 or 400 microg of DNA-hsp65. Toxicity was graded according to CTCAE directions. Tumor volume was measured before and after treatment using computed tomography scan. The evaluation included tumor mass variation, delayed-type hypersensitivity response and spontaneous peripheral blood mononuclear cell proliferation before and after treatment. The MTD was 400 microg per dose. DNA-hsp65 immunotherapy was well tolerated with moderate pain, edema and infections as the most frequent adverse effects. None of the patients showed clinical or laboratory alterations compatible with autoimmune reactions. Partial response was observed in 4 out of 14 patients who completed treatment, 2 of which are still alive more than 3 years after the completion of the trial. Therefore, DNA-hsp65 immunotherapy is a feasible and safe approach at the dose of 400 microg per injection in patients with HNSCC refractory to standard treatment. Further studies in a larger number of patients are needed to confirm the efficacy of this novel strategy.

Abstract
Behcet's disease (BD) is a chronic, recurrent, inflammatory, multisystemic disorder characterized primarily by vasculitis. The etiopathogenesis of BD involves immunogenetics, infectious organisms (streptococcus, herpes simplex virus), immunoregulation and vascular dysfunctions. We previously found that immunoregulation associated with viral infection was important to the development of BD-like symptoms. Recently, we demonstrated that Th2 cytokines up-regulated by Th2 adjuvant were efficient in attenuating or improving these BD-like symptoms. In order to directly augment IL-4 expression, a DNA vector (pCIN-mIL-4) was administered to BD-like mice using the Helios gene gun system. Two injections of the pCIN-mIL-4 vector, spread over 2 weeks, attenuated or improved the mucocutaneous symptoms of 10 out of 12 BD-like mice in our study. The improved mucocutaneous symptoms were crust in face, ulcer in mouth, scruff, back, genital and erythema. This improvement also correlated with induction of IL-4 mRNA in lymph nodes, protein in serum and intracellular IL-4 staining in splenocytes. Normal control mice (n = 10) injected with the pCIN-mIL-4 vector expressed IL-4 mRNA and showed more splenocytes stained with anti-IL-4 antibody (5.77 +/- 0.92%) than did mice injected with the pCIN control vector (3.34 +/- 0.25%; p = 0.02). These findings indicate that an IL-4 DNA vector could be used to express mRNA and protein in vivo and further suggest that such an IL-4 DNA vector could be used as a therapeutic treatment in recurrent inflammation shifted to T helper type 1 cytokine production.

Abstract
The great challenges for researchers working in the field of vaccinology are optimizing DNA vaccines for use in humans or large animals and creating effective single-dose vaccines using appropriated controlled delivery systems. Plasmid DNA encoding the heat-shock protein 65 (hsp65) (DNAhsp65) has been shown to induce protective and therapeutic immune responses in a murine model of tuberculosis (TB). Despite the success of naked DNAhsp65-based vaccine to protect mice against TB, it requires multiple doses of high amounts of DNA for effective immunization. In order to optimize this DNA vaccine and simplify the vaccination schedule, we coencapsulated DNAhsp65 and the adjuvant trehalose dimycolate (TDM) into biodegradable poly (DL-lactide-co-glycolide) (PLGA) microspheres for a single dose administration. Moreover, a single-shot prime-boost vaccine formulation based on a mixture of two different PLGA microspheres, presenting faster and slower release of, respectively, DNAhsp65 and the recombinant hsp65 protein was also developed. These formulations were tested in mice as well as in guinea pigs by comparison with the efficacy and toxicity induced by the naked DNA preparation or BCG. The single-shot prime-boost formulation clearly presented good efficacy and diminished lung pathology in both mice and guinea pigs.

Selection of novel TB vaccine candidates and their evaluation as DNA vaccines against aerosol challenge. Vaccine 2006; 24:6340-50.

Abstract
Putative TB vaccine candidates were selected from lists of genes induced in response to in vivo-like stimuli, such as low oxygen and carbon starvation or growth in macrophages, and tested as plasmid DNA vaccines for their ability to protect against Mycobacterium tuberculosis challenge in a guinea pig aerosol infection model. This vaccination method was chosen as it induces the Th1 cell-mediated immune response required against intracellular pathogens such as M. tuberculosis. Protection was assessed in the guinea pig model in terms of mycobacteria present in the lungs at 30 days post-challenge. Protection achieved by the novel candidates was compared to BCG (positive control) and saline (negative control). Four vaccines encoding for proteins such as PE and PPE proteins, a zinc metalloprotease and an acyltransferase, gave a level of protection that was statistically better than saline in the lungs. These findings have enabled us to focus on a sub-set of vaccine candidates for further evaluation using additional vaccination strategies.

Abstract
A selection of previously identified protective Mycobacterium tuberculosis DNA vaccines were re-formulated as proteins and administered with a Th1-inducing adjuvant to help stimulate the relevant immune responses necessary for protection. All three candidate-vaccines conferred high levels of antigen-specific cellular and humoral responses, as indicated by lymphocyte proliferation and serum IgG levels. Protective efficacy was also assessed in comparison with the current vaccine, BCG (the 'gold-standard' against which new vaccines are tested), and a saline (negative) control. One candidate (Rv1806-1807) induced protection in the guinea pig aerosol infection model 30 days post-challenge on the basis of reducing the bacterial burden of M. tuberculosis in the lungs.

Abstract
Heat shock proteins (HSPs) are highly conserved among different organisms. A mycobacterial HSP65 DNA vaccine was previously shown to have prophylactic and immunotherapeutic effects against Mycobacterium tuberculosis infection in mice. Here, BALB/c mice were immunized with mycobacterial DNA-hsp65 or with DNA-hsp65 and trehalose dymicolate (TDM), both carried by biodegradable microspheres (MHSP/TDM), and challenged with Leishmania (Leishmania) major. MHSP/TDM conferred protection against L. major infection, as indicated by a significant reduction of edema and parasite loads in infected tissues. Although high levels of interferon-gamma and low levels of interleukin (IL)-4 and IL-10 were detected in mice immunized with DNA-hsp65 or MHSP/TDM, only animals immunized with MHSP/TDM displayed a consistent Th1 immune response, i.e., significantly higher levels of anti-soluble Leishmania antigen (SLA) immunoglobulin G (IgG)2a and low anti-SLA IgG1 antibodies. These findings indicate that encapsulated MHSP/TDM is more immunogenic than naked hsp65 DNA, and has great potential to improve vaccine effectiveness against leishmaniasis and tuberculosis.

Abstract
We investigated the immunogenicity and protective efficacy of DNA vaccine combinations expressing mycobacterial heat shock protein 65 (Hsp65) and interleukin-12 (IL-12) using gene gun bombardment and the hemagglutinating virus of Japan (HVJ)-liposome method. A mouse IL-12 expression vector (mIL-12 DNA) encoding single-chain IL-12 proteins comprised of p40 and p35 subunits were constructed. In a mouse model, a single gene gun vaccination with the combination of Hsp65 DNA and mIL-12 DNA provided a remarkably high degree of protection against challenge with virulent Mycobacterium tuberculosis; bacterial numbers were 100-fold lower in the lungs compared to BCG-vaccinated mice. To explore the clinical use of the DNA vaccines, we evaluated HVJ-liposome encapsulated Hsp65 DNA and mIL-12DNA (Hsp65 + mIL-12/HVJ). The HVJ-liposome method improved the protective efficacy of the Hsp65 DNA vaccine compared to gene gun vaccination. Hsp65 + mIL-12/HVJ induced CD8+ cytotoxic T lymphocyte activity against Hsp65 antigen. Most importantly, Hsp65+mIL-12/HVJ vaccination resulted in a greater degree of protection than that evoked by BCG. This protective efficacy was associated with the emergence of IFN-gamma-secreting T cells and activation of proliferative T cells and cytokines (IFN-gamma and IL-2) production upon stimulation with Hsp65 and antigens from M. tuberculosis. These results suggest that Hsp65 + IL-12/HVJ could be a promising candidate for a new tuberculosis DNA vaccine, which is superior to BCG vaccine.

Abstract
Tuberculosis (TB) remains a threat for public health, killing around 3 million people a year. Despite the fact that most cases can be cured with antibiotics, the treatment is long and patients relapse if chemotherapy is not continued for at least 6 months. Thus, a better characterization of the working principles of the immune system in TB and identification of new immunotherapeutic products for the development of shorter regimens of treatment are essential to achieve an effective management of this disease. In the present work, we demonstrate that immunotherapy with a plasmid DNA encoding the Mycobacterium leprae 65 kDa heat-shock protein (hsp65) in order to boost the efficiency of the immune system, is a valuable adjunct to antibacterial chemotherapy to shorten the duration of treatment, improve the treatment of latent TB infection and be effective against multidrug-resistant bacilli (MDR-TB). We also showed that the use of DNA-hsp65 alone or in combination with other drugs influence the pathway of the immune response or other types of inflammatory responses and should augment our ability to alter the course of immune response/inflammation as needed, evidencing an important target for immunization or drug intervention.

Abstract
Over the last 5 years, physical methods of plasmid delivery have revolutionized the efficiency of nonviral gene transfer, in some cases reaching the efficiencies of viral vectors. In vivo electroporation dramatically increases transfection efficiency for a variety of tissues. Other methods with clinical precedent, pressure-perfusion and ultrasound, also improve plasmid gene transfer. Alternatives such as focused laser, magnetic fields and ballistic (gene gun) approaches can also enhance delivery. As plasmid DNA appears to be a safe gene vector system, it seems likely that plasmid with physically enhanced delivery will be used increasingly in clinical trials.

Abstract
Vacinas de DNA, ainda em fase de experimentação e testes clínicos, podem se tornar uma importante ferramenta de combate a doenças infecciosas para as quais, até hoje, não existe prevenção segura e eficaz, como a tuberculose. Nos últimos anos vários estudos têm sido dedicados ao desenvolvimento de vacinas de DNA que codificam proteínas de micobactérias, entre as quais destacam-se as que codificam o antígeno 85 (Ag 85) e a proteína de choque térmico de 65 kDa (hsp65). Estes dois antígenos foram os mais estudados apresentando resultados bastante satisfatórios em ensaios pré-clínicos e com grande volume de dados registrados na literatura. Além de proteger contra infecção experimental por Mycobacterium tuberculosis virulenta, a vacina DNA-hsp65 também apresenta atividade terapêutica, ou seja, é capaz de curar os animais previamente infectados, inclusive aqueles com bacilos resistentes a múltiplas drogas. Esta vacina, hoje em avaliação clínica no Brasil também para o tratamento de câncer, é capaz de induzir a produção de citocinas de padrão Th1 tal como IFN- interferon-gama, associadas ao controle da doença. Além disso, a vacina de DNA-hsp65 é capaz de estimular clones de células CD8 citotóxicos e CD4 que podem ser caracterizados como células de memória sendo responsáveis por conferir imunidade duradoura contra a infecção. Quando utilizada na terapia da infecção, a vacina de DNA-hsp65 faz com que haja uma mudança no padrão de resposta imune, induzindo a secreção de citocinas de padrão Th1 criando um ambiente favorável à erradicação do bacilo. Os resultados demonstram ainda que a via de administração e a formulação na qual a vacina é administrada exerce fundamental influência no padrão e duração da resposta imune desencadeada. O conjunto de resultados hoje disponíveis mostra que uma vacina de DNA contra a tuberculose contribuirá de maneira significativa no controle desta doença.

Abstract
The use of protein or DNA in vaccination process rather than living or attenuated microorganism, aims at the increase of the vaccines safety. However, in these cases, the use of adjuvant is frequently required to improve their immunogenicity. In this study, we show the importance of the adjuvant in a vaccine formulation. Vaccines for tuberculosis provide an instructive example, based on the mycobacterial 65 kDa heat shock protein (hsp65). The same antigen can elicit completely different patterns of immune response depending on how it is administered. Thus, the same antigen might or not protect mice from challenge with Mycobacterium tuberculosis, depending on the formulation. These data suggest that, despite the name, the adjuvant plays a fundamental role on the vaccination process.
