Abstract
Attempts were made to improve the efficacy of PCR amplified immunoassay (I-PCR) for diagnosing abdominal TB cases by utilizing the gold nanoparticle (AuNP)-based I-PCR, where AuNPs were functionalized with detection antibodies/oligonucleotides that exhibited 84.3% sensitivity and 95.1% specificity. This assay would improve the ongoing algorithms used in abdominal TB diagnosis.

Abstract
Tuberculosis (TB) currently remains a major life-threatening disease as it can be fatal if not treated properly or in a timely manner. Herein, we first describe a disposable and cost-effective paper-based electrochemical biosensor based on a gold particle-decorated carboxyl graphene (AuPs/GCOOH)-modified electrode for detecting heat shock protein (Hsp16.3), which is a specific biomarker indicating the onset of TB infection. The device pattern was first engineered to facilitate detection procedures and printed on low-cost filter paper to create hydrophobic and hydrophilic regions using a wax printing technique. Immunoassays proceeded in a half-sandwich format because it is a reagent-less approach and requires no labeling step. The fabrication of the immunosensor began with GCOOH drop casting, the electrochemical deposition of AuPs, and the establishment of a biorecognition layer against Hsp16.3 utilizing 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC)/N-hydroxysuccinimide (NHS)-sulfo standard chemistry. The appearance of Hsp16.3 resulted in a substantial decrease in the electrochemical signal response of the redox probe employed [Fe (CN)6]3-/4- due to the created immunocomplexes that possess insulation properties. GCOOH enables direct antibody immobilization, and AuPs enhance the electrochemical properties of the sensor. This proposed immunosensor, while requiring only a miniscule sample volume (5 μL), achieved superior performance in terms of the limit of detection, measuring at 0.01 ng/mL. Our platform was confirmed to be highly specific to Hsp16.3 and can rapidly detect TB-infected sera without necessitating any pre-enrichment (20 min), making it an alternative and particularly suitable for the early diagnosis of TB in resource-scarce countries.

Abstract
Macrophage is believed to play a vital role in the fight against Mycobacterium tuberculosis (M.tb) infection by activating autophagy. Recently, receptor-interacting protein kinase-3 (RIP3), an essential kinase for necroptotic cell death signaling, has been demonstrated to be involved in autophagy. However, RIP3's role in fighting against M.tb infection remains elusive. Here we show that a substantial increase in inflammatory cell infiltration and higher bacterial burden are observed in the lungs of RIP3-/- mice with Mycobacterium bovis Bacillus Calmette-Guerin (BCG) infection. Meanwhile, RIP3 ameliorates lung injury and promote autophagy via induce autophagosome and autophagolysosome formation which indicate that RIP3 is indispensable for host clearance of BCG via autophagy. Mechanically, RIP3 enhances p62 binding to ubiquitylated proteins and LC3 by interacting with p62, and RHIM domain is required for RIP3-p62 interaction. Hence, our results conclusively show that RIP3 impedes M.tb survival and promotes p62-mediated autophagy. The findings provide further insight into understanding the mechanism of M.tb immune escape and pathogenesis of tuberculosis.

Abstract
Adenosine triphosphate (ATP) is an important fuel of life for humans and Mycobacterium species. Its potential role in modulating cellular functions and implications in systemic, pulmonary, and ocular diseases is well studied. Plasma ATP has been used as a diagnostic and prognostic biomarker owing to its close association with disease’s progression. Several stresses induce altered ATP generation, causing disorders and illnesses. Small heat shock proteins (sHSPs) are dynamic oligomers that are dominantly β-sheet in nature. Some important functions that they exhibit include preventing protein aggregation, enabling protein refolding, conferring thermotolerance to cells, and exhibiting anti-apoptotic functions. Expression and functions of sHSPs in humans are closely associated with several diseases like cataracts, cardiovascular diseases, renal diseases, cancer, etc. Additionally, there are some mycobacterial sHSPs like Mycobacterium leprae HSP18 and Mycobacterium tuberculosis HSP16.3, whose molecular chaperone functions are implicated in the growth and survival of pathogens in host species. As both ATP and sHSPs, remain closely associated with several human diseases and survival of bacterial pathogens in the host, therefore substantial research has been conducted to elucidate ATP-sHSP interaction. In this mini review, the impact of ATP on the structure and function of human and mycobacterial sHSPs is discussed. Additionally, how such interactions can influence the onset of several human diseases is also discussed.

Auld SC, Staitieh BS. HIV and the tuberculosis "set point": how HIV impairs alveolar macrophage responses to tuberculosis and sets the stage for progressive disease. Retrovirology 2020; 17:32. [PMID: 32967690 PMCID: PMC7509826 DOI: 10.1186/s12977-020-00540-2] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2020] [Accepted: 09/15/2020] [Indexed: 11/16/2022] Open
Abstract
As HIV has fueled a global resurgence of tuberculosis over the last several decades, there is a growing awareness that HIV-mediated impairments in both innate and adaptive immunity contribute to the heightened risk of tuberculosis in people with HIV. Since early immune responses to Mycobacterium tuberculosis (Mtb) set the stage for subsequent control or progression to active tuberculosis disease, early host-pathogen interactions following Mtb infection can be thought of as establishing a mycobacterial "set point," which we define as the mycobacterial burden at the point of adaptive immune activation. This early immune response is impaired in the context of HIV coinfection, allowing for a higher mycobacterial set point and greater likelihood of progression to active disease with greater bacterial burden. Alveolar macrophages, as the first cells to encounter Mtb in the lungs, play a critical role in containing Mtb growth and establishing the mycobacterial set point. However, a number of key macrophage functions, ranging from pathogen recognition and uptake to phagocytosis and microbial killing, are blunted in HIV coinfection. To date, research evaluating the effects of HIV on the alveolar macrophage response to Mtb has been relatively limited, particularly with regard to the critical early events that help to dictate the mycobacterial set point. A greater understanding of alveolar macrophage functions impacted by HIV coinfection will improve our understanding of protective immunity to Mtb and may reveal novel pathways amenable to intervention to improve both early immune control of Mtb and clinical outcomes for the millions of people worldwide infected with HIV.

MicroRNA-889 Inhibits Autophagy To Maintain Mycobacterial Survival in Patients with Latent Tuberculosis Infection by Targeting TWEAK. mBio 2020; 11:mBio.03045-19.

Abstract
Autophagy plays an important role in protecting the host against pathogens. Mycobacterium tuberculosis can suppress autophagy and then remain dormant and survive within the host for an extended period, which is responsible for latent tuberculosis infection (LTBI). Here, we explored the role of microRNAs (miRNAs) in LTBI. The miRNA profiles were explored using the next-generation sequencing approach, followed by quantitative reverse transcription-PCR validation. The biological function of candidate miRNA was evaluated using immunoblotting, immunofluorescence techniques, and enzyme-linked immunosorbent assay in an in vitro human TB granuloma model. An increased miR-889 expression was observed in patients with LTBI compared with that in patients without infection. The reporter assay identified tumor necrosis factor (TNF)-like weak inducer of apoptosis (TWEAK) as the target of miR-889. Mycobacterial infection induced TWEAK upregulation in the early phase. TWEAK induced autophagy and promoted mycobacterial autophagosome maturation through activation of AMP-activated protein kinase (AMPK). Upon entry to LTBI status, elevated miR-889 levels were associated with TNF alpha (TNF-α) and granuloma formation/maintenance. MiR-889 inhibited autophagy via posttranscriptional suppression of TWEAK expression to maintain mycobacterial survival in granulomas. Adalimumab (anti-TNF-α monoclonal antibody) treatment reduced levels of both TNF-α and miR-889 and caused granuloma destruction and LTBI reactivation. The circulating miR-889 and TWEAK levels were correlated with LTBI and subsequently associated with anti-TNF-α-related LTBI reactivation in patients. We propose that miR-889 and TWEAK can act as targets that can be manipulated for antimycobacterial therapeutic purposes and act as candidate biomarkers for LTBI and LTBI reactivation, respectively.IMPORTANCE TB remains a leading cause of morbidity and mortality worldwide. Approximately one-quarter of the world's population has latent TB infection. TWEAK is a multiple-function cytokine and may be used as a target for the treatment of rheumatic diseases, cardiovascular diseases, and renal diseases. Here, we demonstrated a novel relationship between TWEAK and activation of the autophagic machinery which promotes antimycobacterial immunity. Additionally, TB infection is highly dynamic and determined by the interaction between the host and mycobacterium. We demonstrated a mechanism of fine-tuned balance between the mycobacterium and host for granuloma formation and/or maintenance in LTBI status. Once patients entered LTBI status, the upregulation of miR-889 was associated with TNF-α levels and granuloma formation to maintain mycobacterial survival. Adalimumab (a TNF-α inhibitor) reduced both TNF-α and miR-889 levels and caused LTBI reactivation and, thus, TWEAK enhancement. MiR-889 and TWEAK may become potential diagnostic biomarkers or therapeutic targets for LTBI and LTBI reactivation, respectively.

Abstract
Tuberculosis (TB), caused by Mycobacterium tuberculosis (Mtb), is one of leading causes of global deaths. This study aimed to explore the role of miR-18a in RAW264.7 cells response to Mtb infection. Exosomes derived from Mtb-infected cells were isolated and further validated by size, transmission electron microscopy and Western blot. RT-PCR was utilized to measure miR-18a expression. Cell viability and ultrastructure were examined by CFU counting, CCK-8 and electron microscope, respectively. Potential target genes of miR-18a were predicted with bioinformatics and further confirmed using RT-PCR, Western blot and laser confocal microscope analysis, respectively. LC3, AMPK and mTOR were measured using Western blot. We found that miR-18a was induced both in Mtb-infected RAW264.7 cells and its derived exosomes compared with the controls. In addition, up-regulation of miR-18a promoted intracellular Mtb survival, attenuated cell viability and reduced LC3-II level, while its down-regulation had the opposite effect. miR-18a overexpression suppressed level of ATM, one possible target of miR-18a, while its underexpression enhanced ATM. We also found that inhibition of ATM induced LC3-II decrease in Mtb-infected cells and could reverse the increase of LC3-II caused by inhibition of miR-18a. Moreover, down-regulation of miR-18a increased p-AMPK level while reduction of ATM could reverse the change. Taken together, our results suggest that miR-18a is up-regulated in macrophages response to Mtb infection, and it promotes intracellular Mtb survival through repressing autophagic process by down-regulation of ATM pathway. This provides new thought for TB pathogenesis, diagnosis and treatment.

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.
