SLC11A1 genetic variation and low expression may cause immune response impairment in TB patients. Genes Immun 2022; 23:85-92. [PMID: 35140349 DOI: 10.1038/s41435-022-00165-9] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2021] [Revised: 01/19/2022] [Accepted: 01/27/2022] [Indexed: 12/13/2022]
Abstract
Tuberculosis (TB) is caused by Mycobacterium tuberculosis. Host genetic factors are important for the detection of TB susceptibility. SLC11A1 is located in monocyte phagolysosomes that help to limit M. tuberculosis growth by transferring divalent cations across the membrane. Genetic variation in SLC11A1 may alter its expression and increase the susceptibility of individuals to TB. The current study aimed to provide insight into host genetic variations and gene expression in TB patients. A total of 164 TB patients and 85 healthy controls were enrolled in this study. SLC11A1 polymorphisms were detected by PCR-RFLP. Real-time qPCR was used for SLC11A1 gene expression, and ELISA was used for protein estimation. GTEx Portal was used for quantitative trait loci analysis, while the STRING (v.11) web platform was used for gene interactive network construction. Data were analyzed using SPSS, GraphPad Prism, Haploview, and SNPstats. SLC11A1 polymorphisms and combinatorial genotypes were strongly associated with TB susceptibility, which may explain the greater prevalence of tuberculosis in the local population. Polymorphisms in SLC11A1 have also been linked to gene expression variation. Furthermore, the expression of SLC11A1 was downregulated in TB patients, which may influence the function of other associated genes and may impair the immunological response to tuberculosis.

Abstract
Background Broad-scale evidence has shown the significant association between ambient air pollutants and the development of tuberculosis (TB). However, the impact of air quality on the risk of TB in Taiwan is still poorly understood. Objective To develop a probabilistic integrated population-level risk assessment approach for evaluating the contribution of ambient air pollution exposure to the risk of TB development among different regions of Taiwan. Materials and methods A Bayesian-based probabilistic risk assessment model was implemented to link exposure concentrations of various air pollutants quantified in a probabilistic manner with the population-based exposure-response models developed by using an epidemiological investigation. Results The increment of the risk of TB occurred in a region with a higher level of air pollution, indicating a strong relationship between ambient air pollution exposures and TB incidences. Carbon monoxide (CO) exposure showed the highest population attributable fraction (PAF), followed by nitrogen oxides (NOX) and nitrogen dioxide (NO2) exposures. In a region with higher ambient air pollution, it is most likely (80% risk probability) that the contributions of CO exposure to development of TB were 1.6–12.2% (range of median PAFs), whereas NOX and NO2 exposures contributed 1.2–9.8% to developing TB. Conclusion Our findings provide strong empirical support for the hypothesis and observations from the literature that poor air quality is highly likely to link aetiologically to the risk of TB. Therefore, substantial reductions in CO, NOX, and NO2 exposures are predicted to have health benefits to susceptible and latently infected individuals that provide complementary mitigation efforts in reducing the burden of TB. Considering that people continue to be exposed to both TB bacilli and ambient air pollutants, our approach can be applied for different countries/regions to identify which air pollutants contribute to a higher risk of TB in order to develop potential mitigation programs.

Abstract
The objective of the present study was to assess the impact of ethnicity on hair trace element content in Han and aboriginal inhabitants of Hualien in Taiwan. Fifty Han (female/male = 35/15) and 50 aboriginal (female/male = 40/10) Hualien inhabitants aged 40-60 years were involved in the present study. Anthropometric data and dietary patterns were recorded. Hair mineral, essential, and toxic trace element levels were assessed using inductively coupled plasma mass spectrometry at NexION 300D (PerkinElmer Inc., USA) equipped with ESI SC-2 DX4 autosampler (Elemental Scientific Inc., USA). No group difference in gender, age, body weight, height, or physical activity was observed. Fish intake was more frequent in Han inhabitants, whereas aborigines consumed significantly more nuts. Indigenous people were characterized by higher hair Al (45%), Ca (threefold), Co (71%), Fe (twofold), I (74%), K (60%), Mg (2.5-fold), Na (62%), P (6%), Sn (78%), and V (46%) content. In turn, Han Hualien inhabitants had higher hair Be (twofold), Li, Se, Si levels as compared to indigenous counterparts. Multiple regression analysis demonstrated that ethnicity was significantly associated with hair Ca (β = 0.302), Mn (β = 0.284), P (β = 0.387), and Se (β = - 0.310) levels after adjustment for other confounders. At the same time, the overall models were significant for Ca, Mn, Se, and As. The obtained data may provide a background for monitoring and correction of trace element status in patients of different ethnic groups. However, further detailed studies are required to highlight the mechanisms underlying the observed associations.

Abstract
Many studies have investigated the association between the 3'UTR polymorphism in natural resistance-associated macrophage protein 1 (NRAMP1) and the risk of pulmonary tuberculosis (PTB), Revealing inconclusive results. This study aimed to investigate the correlation between the NRAMP1 3'UTR polymorphism and the risk of PTB.This meta-analysis included 29 case-control studies to better and comprehensively assess this correlation. Pooled odds ratios (ORs) and 95% confidence interval (95% CIs) were calculated to assess the strength of the association.These 29 case-control studies included 4672 cases and 6177 controls. The NRAMP1 3'UTR polymorphism displayed a significant positive correlation with the risk of PTB in 3 models (for del/del vs ins/ins: OR = 1.22, 95% CI = 1.01-1.47; for Ins/del vs ins/ins: OR = 1.19, 95% CI 1.08-1.30; for Ins/del + del/del vs ins/ins: OR = 1.25, 95% CI = 1.08-1.45). A stratified analysis by ethnicity revealed that the NRAMP1 3'UTR polymorphism was associated with an increased risk of PTB in the Asian population, but not in Caucasian, African, and South American populations.The present results indicate that the NRAMP1 3'UTR polymorphism may be considered a risk factor for PTB in the Asian population.

Abstract
BACKGROUND Suppressors of cytokine signaling (SOCS), particularly SOCS-3, allow discrimination of patients with active tuberculosis (TB) from healthy subjects in a gender- and age-dependent manner. However, no information is available on whether single nucleotide polymorphisms (SNPs) in the SOCS-3 gene occur in patients with TB. This study was designed to investigate SOCS-3 SNPs in association with susceptibility to TB in the Taiwanese population. METHODS Four SNPs in the SOCS-3 gene located at rs8064821, rs4969168, rs2280148, and rs35037722 were studied by the TaqMan SNP Genotyping assay in 200 healthy and 210 TB patients enrolled in 2015-2018. RESULTS Significant differences were not detected in genotype frequencies or odds ratios (ORs) between healthy and TB patients for any of the four polymorphisms. The lack of significant differences was also found when the patients were stratified by sex. However, males exhibited GG homozygous at rs35037722 in association with susceptibility to TB after the OR analysis was adjusted for age. For rs8064821, AA and AC genotypes were associated with TB susceptibility in patients ≤ 65 years old compared to CC genotype, whereas older subjects had no such association. CONCLUSIONS The results suggest that particular SOCS-3 SNPs are dependent on gender or age to influence TB susceptibility in the Han Taiwanese.

Abstract
ABSTRACT
Familial risk of tuberculosis (TB) has been recognized for centuries. Largely through studies of mono- and dizygotic twin concordance rates, studies of families with Mendelian susceptibility to mycobacterial disease, and candidate gene studies performed in the 20th century, it was recognized that susceptibility to TB disease has a substantial host genetic component. Limitations in candidate gene studies and early linkage studies made the robust identification of specific loci associated with disease challenging, and few loci have been convincingly associated across multiple populations. Genome-wide and transcriptome-wide association studies, based on microarray (commonly known as genechip) technologies, conducted in the past decade have helped shed some light on pathogenesis but only a handful of new pathways have been identified. This apparent paradox, of high heritability but few replicable associations, has spurred a new wave of collaborative global studies. This review aims to comprehensively review the heritability of TB, critically review the host genetic and transcriptomic correlates of disease, and highlight current studies and future prospects in the study of host genomics in TB. An implicit goal of elucidating host genetic correlates of susceptibility to
Mycobacterium tuberculosis
infection or TB disease is to identify pathophysiological features amenable to translation to new preventive, diagnostic, or therapeutic interventions. The translation of genomic insights into new clinical tools is therefore also discussed.

Abstract
Background Contact investigation is an active case finding strategy to increase detection of Tuberculosis (TB) and a key component of TB control programs. The household contacts are at a higher risk of exposure than members of the general population. The information on the value and yield of household contact screening and the approaches used in high incidence settings like India is limited. Objective To evaluate the yield of active case finding in household contacts of newly diagnosed smear positive TB patients and the factors associated with increased yield. Method Retrospective record review of the household contacts of newly diagnosed sputum smear positive patients (index case) enrolled in a clinical trial at National Institute of Research in Tuberculosis, Chennai during the period 2007–2014. A sequential screening algorithm with chest x-ray followed by symptom screen was employed to identify presumptive TB patients. Results 643 household contacts of 280 index TB patients were identified out of which 544 (85%) consented for screening. 71/544 (13%) patients had an abnormal chest radiograph and out of them 70% were symptomatic. A total of 29/544 (5.3%) contacts were found to have TB among whom 23/29 (79%) were sputum smear positive. The number needed to screen (NNS) to identify a new TB case among all household contacts was 19 and among those with an abnormal CXR was 02. Age group > 44 years, male gender and siblings of the index case was associated with abnormal chest radiograph whereas age group between 15–44 was significantly associated with developing TB disease among household contacts. Conclusion Active screening among household contacts is an effective way to improve TB case detection. The yield for new TB cases among contacts with abnormal x-ray was high in this study and the use of Chest X-rays in combination with symptom screen is recommended.

Abstract
BACKGROUND The active metabolite (1, 25-dihydroxycholecalciferol) of vitamin D (25-hydroxycholecalciferol) leads to the activation of macrophages and the deficiency of vitamin D seems to be involved in the risk of tuberculosis (TB). The effects of vitamin D are exerted by interaction with the vitamin D receptor (VDR) and vitamin D receptor binding protein (VDBP) may be influenced by polymorphisms in the VDR and VDBP genes. In this study, variation in the VDR and VDBP genes was investigated in a Taiwanese population with TB. METHODS We typed four VDR polymorphisms of restriction endonuclease sites for ApaI, TaqI, BsmI, and FokI and three VDBP polymorphisms-Thr420Lys, Asp416Glu, and Cys299Cys-in 198 patients with TB and 170 healthy volunteers. RESULTS VDR TaqI, VDR BsmI, and VDBP Asp416Glu were significantly associated with TB susceptibility. Odd ratios of risk genotypes of the above three polymorphisms were 2.16 (95% confidence interval 1.01, 4.65), 2.14 (95% confidence interval 1.06, 4.31), and 2.24 (95% confidence interval 1.04, 4.80), respectively. VDBP haplotype analysis showed Gc1f carriers associated to TB. CONCLUSION The polymorphisms in the VDR and VDBP genes appeared to be responsible for host susceptibility to human TB in a Taiwanese population.

Abstract
Natural resistance-associated macrophage protein (Nramp1) and the vitamin D receptor (VDR) are central components of the innate and adaptive immunity against Mycobacterium tuberculosis, and associations between susceptibility to tuberculosis and polymorphisms in the genes NRAMP and VDR have been sought in geographically diverse populations. We investigated associations of NRAMP1 and VDR gene polymorphisms with susceptibility to TB in the Venezuelan population. The results suggest the absence of any association between VDR variants FokI, ApaI, and TaqI and susceptibility to tuberculosis. In contrast, the NRAMP1 3'UTR variants were associated with susceptibility to M. tuberculosis infection, as seen in the comparisons between TST+ and TST- controls, and also with progression to TB disease, as shown in the comparisons between TB patients and TST+ controls. This study confirms the previously described association of the NRAMP1 3'UTR polymorphism with M. tuberculosis infection and disease progression.

Abstract
Many studies suggest significant genetic variation in the resistance of cattle and humans to infection with
Mycobacterium bovis, the causative agent of zoonotic tuberculosis. The inducible nitric
oxide synthase (iNOS which is encoded by the NOS2 gene) plays a key role in the immunological
control of a broad spectrum of infectious agents. This study aimed to investigate the influence of genetic
variations in the promoter of the NOS2 gene on bovine tuberculosis (bTB) susceptibility. In
this study, the NOS2 genes of 74 bTB-infected Holstein cows and 90 healthy controls were
genotyped using PCR followed by nucleotide sequencing. Polymorphisms at rs207692718, rs109279434, rs209895548,
rs385993919, rs433717754, rs383366213, rs466730386, rs715225976, rs525673647, rs720757654 and g.19958101T>G
in the promoter region of the NOS2 gene were detected. The g.19958101T>G SNP produced two
different conformation patterns (TT and TG) and the TG genotype was over-represented in the bTB group (20.27%)
compared with the control group (2.22%). The TG genotype frequency of the g.19958101T>G variant was
significantly higher in bTB cattle than in healthy controls (OR, 11.19; 95% CI, 2.47–50.73;
P=0.0002). The G allele of the g.19958101T>G polymorphism was more frequent in bTB group
when compared to control group (10.14% versus 1.11%). Furthermore, the G allele was a risk factor for bTB
susceptibility (OR, 10.04; 95% CI, 2.26–44.65; P=0.0002). In conclusion, the g.19958101T>G
polymorphism of the NOS2 gene may contribute to the susceptibility of Holstein cattle to
bTB.

Abstract
Taiwan is a relatively isolated island, serving as a mixing vessel for colonization by different waves of ethnic and migratory groups over the past 4 centuries. The potential transmission pattern of Mycobacterium tuberculosis in different ethnic and migratory populations remains to be elucidated. By using mycobacterial tandem repeat sequences as genetic markers, the prevalence of M. tuberculosis strains in Taiwan revealed a close link to the historical migration. Interestingly, the M. tuberculosis strain in the aborigines of Eastern and Central Taiwan had a dominance of the Haarlem (Dutch) strain while those in Southern Taiwan had a dominance of the East-African Indian (EAI) strain. The prevalence of different M. tuberculosis strains in specific ethnic populations suggests that M. tuberculosis transmission is limited and restricted to close contact. The prevalence of the Beijing modern strain in the young population causes a concern for M. tuberculosis control, because of high virulence and drug resistance. Furthermore, our data using molecular genotyping should provide valuable information on the historical study of the origin and migration of aborigines in Taiwan.

Abstract
A single nucleotide polymorphism (SNP) rs4331426 located in a gene-poor region on chromosome 18q11.2 has been associated with tuberculosis (TB) by genome-wide association studies in Ghana and Gambia. In this study, we analyzed the SNP rs4331426 for its association with the risk of TB in the Taiwanese population. The SNP rs4331426 was genotyped in a case-control design that included 377 Han Taiwanese (200 TB patients and 177 controls) and was associated with TB (marginally significant p = 0.078). An increasingly significant association was observed after adjusting for sex in the logistic regression analysis (p = 0.029). Furthermore, the G carrier (AG genotype) conferred the risk of TB in females (p = 0.011), but not in males. These findings indicate that the SNP rs4331426 associated with TB in the Han Taiwanese population, especially in females. Further investigations on its role and that of the genomic region surrounding it are warranted.

Distinct modes of transmission of tuberculosis in aboriginal and non-aboriginal populations in Taiwan. PLoS One 2014; 9:e112633.

Abstract
Tuberculosis incidence among aborigines is significantly higher than for Han Chinese in Taiwan, but the extent to which Mycobacterium tuberculosis (MTB) strain characteristics contribute to this difference is not well understood. MTB isolates from aborigines and Han Chinese living in eastern and southern Taiwan, the major regions of aborigines, were analyzed by spoligotyping and 24-loci MIRU-VNTR. In eastern Taiwan, 60% of aboriginal patients were ≤20 years old, significantly younger than the non-aboriginal patients there; aborigines were more likely to have clustered MTB isolates than Han Chinese (odds ratio (OR) = 5.98, p<0.0001). MTB lineages with high clustering were EAI (54.9%) among southern people, and Beijing (62.5%) and Haarlem (52.9%) among eastern aborigines. Resistance to first-line drugs and multidrug resistance (MDR) were significantly higher among eastern aborigines (≥15%) than in any other geographic and ethnic group (p<0.05); MDR was detected in 5 of 28 eastern aboriginal patients ≤20 years old. Among patients from the eastern region, clustered strains (p = 0.01) and aboriginal ethnicity (p = 0.04) were independent risk factors for MDR. The lifestyles of aborigines in eastern Taiwan may explain why the percentage of infected aborigines is much higher than for their Han Chinese counterparts. The significantly higher percentage of the MDR-MTB strains in the aboriginal population warrants close attention to control policy and vaccination strategy.

Abstract
Particle exposures increase the risk for human infections. Particles can deposit in the nose, pharynx, larynx, trachea, bronchi, and distal lung and, accordingly, the respiratory tract is the system most frequently infected after such exposure; however, meningitis also occurs. Cigarette smoking, burning of biomass, dust storms, mining, agricultural work, environmental tobacco smoke (ETS), wood stoves, traffic-related emissions, gas stoves, and ambient air pollution are all particle-related exposures associated with an increased risk for respiratory infections. In addition, cigarette smoking, burning of biomass, dust storms, mining, and ETS can result in an elevated risk for tuberculosis, atypical mycobacterial infections, and meningitis. One of the mechanisms for particle-related infections includes an accumulation of iron by surface functional groups of particulate matter (PM). Since elevations in metal availability are common to every particle exposure, all PM potentially contributes to these infections. Therefore, exposures to wood stove emissions, diesel exhaust, and air pollution particles are predicted to increase the incidence and prevalence of tuberculosis, atypical mycobacterial infections, and meningitis, albeit these elevations are likely to be small and detectable only in large population studies. Since iron accumulation correlates with the presence of surface functional groups and dependent metal coordination by the PM, the risk for infection continues as long as the particle is retained. Subsequently, it is expected that the cessation of exposure will diminish, but not totally reverse, the elevated risk for infection.

Abstract
Transition metals occupy an essential niche in biological systems. Their electrostatic properties stabilize substrates or reaction intermediates in the active sites of enzymes, and their heightened reactivity is harnessed for catalysis. However, this heightened activity also renders transition metals toxic at high concentrations. Bacteria, like all living organisms, must regulate their intracellular levels of these elements to satisfy their physiological needs while avoiding harm. It is therefore not surprising that the host capitalizes on both the essentiality and toxicity of transition metals to defend against bacterial invaders. This Review discusses established and emerging paradigms in nutrient metal homeostasis at the pathogen-host interface.

Abstract
BACKGROUND Natural resistance associated macrophage protein 1 (NRAMP1), encoded by the SLC11A1 gene, has been described to regulate macrophage activation and be associated with infectious and autoimmune diseases. The relation between SLC11A1 polymorphisms and tuberculosis susceptibility has been studied in different populations. METHODS We systematically reviewed published studies on SLC11A1 polymorphisms and tuberculosis susceptibility until September 15, 2010 and quantitatively summarized associations of the most widely studied polymorphisms using meta-analysis. RESULTS In total, 36 eligible articles were included in this review. In Meta-analysis, significant associations were observed between tuberculosis risk and widely studied SLC11A1 polymorphisms with summarized odds ratio of 1.35 (95%CI, 1.17-1.54), 1.25 (95% CI, 1.04-1.50), 1.23 (95% CI, 1.04-1.44), 1.31 (95%CI, 1.08-1.59) for 3' UTR, D543N, INT4, and 5' (GT)n, respectively. Heterogeneity between studies was not pronounced, and the associations did not remarkably vary in the stratified analysis with respect to study population and study base. CONCLUSIONS The association between SLC11A1 polymorphisms and tuberculosis susceptibility observed in our analyses supports the hypothesis that NRAMP1 might play an important role in the host defense to the development of tuberculosis.

Abstract
The global evolution and spread of Mycobacterium tuberculosis (MTB), one of the most successful bacterial pathogens, remain a mystery. Advances in molecular technology in the past decade now make it possible to understand MTB strain evolution and transmission in the context of human population migration. Taiwan is a relatively isolated island, serving as a mixing vessel over the past four centuries as colonization by different waves of ethnic groups occurred. By using mycobacterial tandem repeat sequences as genetic markers, the prevalence of MTB strains in Taiwan revealed an interesting association with historical migrations of different ethnic populations, thus providing a good model to explore the global evolution and spread of MTB.

Abstract
Crohn's disease (CD) is often considered to be an autoimmune condition or, alternatively, an autoinflammatory condition, based on the observation of host-directed inflammatory processes. However, the underlying basis of this deleterious inflammatory response remains elusive. Recent findings from genetic and genomic studies have altered the perspective on the pathogenesis of CD, hinting at defects in innate immune sensing of intracellular bacteria and the handling of these organisms through autophagy. These findings are consistent with emerging data from immunological studies that point to a systemic immune deficiency in CD patients. Both sets of data (genetic predisposition and immunodeficiency) are consistent with the longstanding hypothesis that mycobacteria might be involved in the etiology of CD. In this article, we discuss the convergence of these three lines of investigation and highlight important knowledge gaps required in order to address the mycobacterial hypothesis with greater clarity. In the coming years, clinical immunological investigations should focus on defining the specificity of functional immune defects with regards to microbes and their associated ligands. Should CD result from a dysfunctional host-pathogen interaction, elucidation of the microbes that can exploit such defects to induce a chronic inflammatory disease is critical for the development of subsequent diagnostic assays and clinical interventions.

Abstract
BACKGROUND Spatial analytical techniques and models are often used in epidemiology to identify spatial anomalies (hotspots) in disease regions. These analytical approaches can be used to not only identify the location of such hotspots, but also their spatial patterns. METHODS In this study, we utilize spatial autocorrelation methodologies, including Global Moran's I and Local Getis-Ord statistics, to describe and map spatial clusters, and areas in which these are situated, for the 20 leading causes of death in Taiwan. In addition, we use the fit to a logistic regression model to test the characteristics of similarity and dissimilarity by gender. RESULTS Gender is compared in efforts to formulate the common spatial risk. The mean found by local spatial autocorrelation analysis is utilized to identify spatial cluster patterns. There is naturally great interest in discovering the relationship between the leading causes of death and well-documented spatial risk factors. For example, in Taiwan, we found the geographical distribution of clusters where there is a prevalence of tuberculosis to closely correspond to the location of aboriginal townships. CONCLUSIONS Cluster mapping helps to clarify issues such as the spatial aspects of both internal and external correlations for leading health care events. This is of great aid in assessing spatial risk factors, which in turn facilitates the planning of the most advantageous types of health care policies and implementation of effective health care services.

Abstract
The distribution of human Mycobacterium tuberculosis (MTB) genotypes is reportedly associated with geography, ethnicity and population migrations. Three groups of 208 patients with tuberculosis in Taiwan were sampled to test this observation: (1) 41 aborigines of Austronesian ethnicity, who have been inhabiting in Taiwan for more than 500 years; (2) 58 veterans of Han Chinese origin, who moved as the first generation from Mainland China to Taiwan 55-60 years ago; and (3) 109 patients representing the general Taiwanese population of Han Chinese whose ancestors migrated to Taiwan around 200-400 years ago. A total of 208 MTB isolates, one per patient, were analyzed by spoligotyping and mycobacterial interspersed repetitive unit (MIRU) typing. Beijing ancient strains and Haarlem strains predominated among aborigines, while Beijing modern strains were common among veterans and the general population. All Beijing strains were further analyzed by typing the NTF loci and RD deletion. Results suggest a chronological trend among Beijing isolates from the three groups: isolates from the aborigines had signatures compatible with ancient lineages, and those from veterans and the general population were more contemporary. Our data indicate that the distribution of MTB genotypes/strains in Taiwan is associated with different populations whose migratory activities occurred between 55 and 500 years ago. These results suggest that transmission of MTB may have been relatively restricted to close contacts.
