Abstract
Ankylosing spondylitis (AS) is a chronic autoimmune disease. The purpose of this study was to investigate the levels of serum IL-36γ in AS patients and their association with AS. The study enrolled 131 subjects, including 45 with active AS, 46 with inactive AS, and 40 healthy controls (HCs). The basic clinical information of each participant was obtained through physical examination and relevant clinical medical records. Serum IL-36γ levels were detected through an enzyme-linked immunosorbent assay. Serum IL-36γ levels in the active AS group were significantly higher than those in the HC group (94.72 vs. 65.76 pg/mL, P = 0.0087). The serum IL-36γ concentration in the inactive AS group was increased as compared to that in the HC group (100.90 vs. 65.76 pg/mL, P = 0.0138). Correlation analysis indicated that serum IL-36γ was positively correlated with glutamyl transferase in the active AS group (P = 0.0172), while serum IL-36γ was positively correlated with uric acid in the inactive AS group (P = 0.0151). The area under the curve (AUC) for IL-36γ was 0.6824 (P = 0.0009), and the AUC for IL-36γ combined with the erythrocyte sedimentation rate and C-reactive protein levels was 0.8102 (P < 0.0001), according to receiver operating characteristic curve analysis. This study found that serum IL-36γ levels were elevated in AS patients and correlated with disease activity. Our results suggest that IL-36γ may be involved in the progression of AS disease and is a potential biomarker for AS.

Abstract
Exposure to heavy metals and lifestyle factors like smoking contribute to the production of free oxygen radicals. This fact, combined with a lowered total antioxidant status, can induce even more damage in the development of ankylosing spondylitis (AS). Despite the fact that some researchers are looking for more genetic factors underlying AS, most studies focus on polymorphisms within the genes encoding the human leukocyte antigen (HLA) system. The biggest challenge is finding the effective treatment of the disease. Genetic factors and the influence of oxidative stress, mineral metabolism disorders, microbiota, and tobacco smoking seem to be of great importance for the development of AS. The data contained in this review constitute valuable information and encourage the initiation and development of research in this area, showing connections between inflammatory disorders leading to the pathogenesis of AS and selected environmental and genetic factors.

Abstract
BACKGROUND A case-control study was performed to explore eight pro-inflammatory and anti-inflammatory cytokines, namely interleukin (IL)-1α, IL-1Ra (IL-1 receptor antagonist), IL-12, IL-17A, IL-31, IL-33, CXCL10 (C-X-C motif chemokine ligand 10), and CXCL16, with the aim to understand their role in ankylosing spondylitis (AS) pathogenesis and evaluate their utility as markers to differentiate between diseased and healthy individuals. Among these cytokines, IL-31 and CXCL16 have not been well studied in AS. PATIENTS AND METHODS The study included 94 male patients with AS and 91 age-matched control males. Interleukin and chemokine levels were measured using ELISA kits. RESULTS Serum levels of IL-17A, CXCL10, and CXCL16 were significantly elevated in patients compared to controls, while IL-31 levels were significantly decreased in patients. IL-17A, CXCL10, and CXCL16 were associated with an increased risk of AS, while IL-31 was associated with a decreased risk of disease (odds ratio = 1.22, 1.78, 1.14, and 0.89, respectively). As indicated by the area under the curve (AUC), IL-17A, IL-31, CXCL10, and CXCL16 were potential markers to differentiate between AS patients and controls (AUC = 0.877, 0.735, 0.8, and 0.7, respectively). IL-1α, IL-1Ra, IL-12, and IL-33 levels showed no significant variations between patients and controls. CONCLUSIONS Among the eight cytokines examined, IL-17A, CXCL10, and CXCL16 were up-regulated in the serum of AS patients, while IL-31 was down-regulated. The levels of IL-1α, IL-1Ra, IL-12, and IL-33 showed no significant differences between patients and controls. Serum levels of all cytokines were not affected by disease duration, HLA-B27 positivity, or disease activity.

Abstract
BACKGROUND Ankylosing spondylitis (AS) is one of several disorders known as seronegative spinal arthritis (SpA), the origin of which is unknown. Existing epidemiological data show that inflammatory and immunological factors are important in the development of AS. Previous research on the connection between immunological inflammation and AS, however, has shown inconclusive results. METHODS To evaluate the causal association between immunological characteristics and AS, a bidirectional, two-sample Mendelian randomization (MR) approach was performed in this study. We investigated the causal connection between 731 immunological feature characteristic cells and AS risk using large, publically available genome-wide association studies. RESULTS After FDR correction, two immunophenotypes were found to be significantly associated with AS risk: CD14 - CD16 + monocyte (OR, 0.669; 95% CI, 0.544 ~ 0.823; P = 1.46 × 10-4; PFDR = 0.043), CD33dim HLA DR + CD11b + (OR, 0.589; 95% CI = 0.446 ~ 0.780; P = 2.12 × 10-4; PFDR = 0.043). AS had statistically significant effects on six immune traits: CD8 on HLA DR + CD8 + T cell (OR, 1.029; 95% CI, 1.015 ~ 1.043; P = 4.46 × 10-5; PFDR = 0.014), IgD on IgD + CD24 + B cell (OR, 0.973; 95% CI, 0.960 ~ 0.987; P = 1.2 × 10-4; PFDR = 0.021), IgD on IgD + CD38 - unswitched memory B cell (OR, 0.962; 95% CI, 0.945 ~ 0.980; P = 3.02 × 10-5; PFDR = 0.014), CD8 + natural killer T %lymphocyte (OR, 0.973; 95% CI, 0.959 ~ 0.987; P = 1.92 × 10-4; PFDR = 0.021), CD8 + natural killer T %T cell (OR, 0.973; 95% CI, 0.959 ~ 0.987; P = 1.65 × 10-4; PFDR = 0.021). CONCLUSION Our findings extend genetic research into the intimate link between immune cells and AS, which can help guide future clinical and basic research.

Abstract
BACKGROUND AND OBJECTIVE Ankylosing spondylitis is a refractory immune disease that seriously affects the life and work of patients. Epigenetic modifications, especially DNA methylation, have become a research hotspot in complex diseases. We aim to explore the changes in runt-related transcription factor 2 (RUNX2) gene promoter methylation and transcription level in AS. METHOD We detected the RUNX2 gene promoter methylation in 83 AS patients and 83 healthy controls (HCs), then inspected the mRNA difference of RUNX2 between 30 AS patients and 30 HCs by the quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR). RESULTS The RUNX2 gene promoter was hypomethylated in AS patients compared to HCs (p < .001). The research involved 4 CpG regions and 74 CpG sites of RUNX2, of which CpG-2, CpG-4 regions, and 18 CpG sites have been differentially methylated. The CpG-4 island methylation was negatively correlated with C-reactive protein (p < .05) in AS patients. In the qRT-PCR validation phase, the mRNA level of RUNX2 in AS patients was significantly higher than HCs (p < .05), and in AS patients who were treated with biologics, the methylation level of CpG-2 island showed a negative correlation to mRNA (p < .05). ROC results indicated that RUNX2 methylation and its transcription level have good potential to distinguish AS patients from HCs. CONCLUSION The RUNX2 gene promoter was hypomethylated in AS patients. Meanwhile, the qRT-PCR verified the up-regulated expression on the transcription level, suggesting the abnormal methylation of RUNX2 contributes to the pathogenesis of AS.

Abstract
BACKGROUND The therapeutic profile of the patients with rheumatoid arthritis (RA) commonly consists of immunosuppressive and anti-inflammatory compounds. Here in this research, we assessed the potential effect of drug treatment in the RA patients in increasing the risk of coronavirus disease 2019 (COVID-19) infection. METHODS In this retrospective cross-sectional study, 200 subjects with RA were recruited. The treatment profile of the subjects for the past 6 months was collected. The COVID-19 diagnosis was implemented based on the standard molecular tests and clinical examinations. Serum concentration of cytokines was measured using enzyme-linked immunosorbent assay (ELISA). RESULTS It was detected that there was an increased risk of COVID-19 in RA subjects receiving Etanercept (OR = 3.51, 95% CI 1.19-10.30, P = 0.022). Concentrations of Interleukin (IL)-1β, Interferon (IFN)-γ, Tumor necrosis factor (TNF)-α, IL-6, IL-17A, and IL-23 were significantly higher in the RA patients with COVID-19 relative to RA cases without COVID-19. In RA/COVID-19 cases receiving Etanercept, serum levels of TNF-α, IL-1β, and IL-6 were significantly lower than RA/COVID-19 subjects without Etanercept therapy. CONCLUSIONS It seems that Etanercept therapy in RA cases might increase proneness of the COVID-19 risk in these cases. The mechanism of this increased risk may stem from suppressing a protective immunity state in the RA cases.

Abstract
Ankylosing spondylitis (AS) is a chronic rheumatic disease, and some microRNAs (miRNAs) in AS have been identified. This study aimed to measure miR-222-3p expression in AS patients, investigate the association of miR-222-3p with AS disease activity, and explore the clinical value of miR-222-3p in diagnosing AS and predicting therapeutic efficacy of nonsteroidal anti-inflammatory drugs (NSAIDs) on AS patients. This study included 96 patients with AS, 58 patients with rheumatoid arthritis (RA), and 90 healthy controls. miR-222-3p expression was detected by reverse-transcription quantitative polymerase chain reaction (PCR). The ability of miR-222-3p to discriminate between different groups was evaluated by receiver operating characteristic analysis. The predictive value of miR-222-3p on the efficacy of NSAID treatment for AS was assessed by logistic regression analysis. AS patients treated with oral NSAIDs diclofenac sodium were divided into response (n = 76) and no-response (n = 20) groups after 16 weeks of treatment. miR-222-3p in AS patients was higher than that in healthy subjects and RA patients. miR-222-3p had high diagnostic value in distinguishing patients with AS from RA patients and healthy controls. miR-222-3p, increased in active AS patients, had the ability to screen active AS patients from inactive AS patients. miR-222-3p was decreased in the response group, and had high accuracy in predicting the therapeutic efficiency of NSAIDs. The findings indicate that increased miR-222-3p in AS patients may function as a diagnostic biomarker for AS, and predictive biomarker for the therapeutic efficacy of NSAIDs in patients with AS. In addition, miR-222-3p is associated with AS disease activity.

Abstract
Ankylosing spondylitis (AS) is a chronic inflammatory rheumatic disease that mainly affects the axial skeleton, whose typical features are inflammatory back pain, bone structural damage and pathological new bone formation. The pathology of ectopic new bone formation is still little known. In this study, we found increased purine metabolites in plasma of patients with AS. Similarly, metabolome analysis indicated increased purine metabolites in both serum of CD4-Cre; Ptpn11fl/fl and SHP2-deficient chondrocytes. SHP2-deficient chondrocytes promoted the growth of wild type chondrocytes and differentiation of osteoblasts in CD4-Cre; Ptpn11fl/fl mice, which spontaneously developed AS-like bone disease. Purine metabolites, along with PTHrP derived from SHP2-deficient chondrocytes, accelerated the growth of chondrocytes and ectopic new bone formation through PKA/CREB signaling. Moreover, Suramin, a purinergic receptor antagonist, suppressed pathological new bone formation in AS-like bone disease. Overall, these results highlight the potential role of targeting purinergic signaling in retarding ectopic new bone formation in AS.

Abstract
BACKGROUND Ankylosing spondylitis (AS) has a high incidence, and severe cases can lead to spinal deformity and even joint fusion, which causes a huge burden on patients life, work and psychology. Tongdu Shujin decoction (TDSJ) has a definite effect in the treatment of ankylosing spondylitis, so we designed a randomized controlled trial to observe the efficacy of TDSJ in the treatment of AS, and to evaluate its safety. METHODS In this randomized controlled trial, 80 eligible patients were randomly assigned in a 1:1 ratio to a treatment group TDSJ and a control group (celecoxib capsules in combination with thalidomide tablets) for 8 weeks. Visual analogue scale, bath ankylosing spondylitis disease activity index, bath ankylosing spondylitis functional index, and traditional Chinese medicine syndrome scores will be used as primary indicators. Erythrocyte sedimentation rate, C-reactive protein, spinal mobility (figure-ground distance, occipital tubercle-wall distance, Schober test) will be used as secondary indicators. Vital signs (respiration, heart rate, body temperature, blood pressure, electrocardiogram), blood routine, urine routine, stool routine, liver function, and renal function will be used as safety indicators. The primary and secondary indicators will be detected at 0th and 8th week, while safety indicators at 0th, 4th, and 8th week. DISCUSSION This study will provide high-quality clinical evidence for the efficacy and safety of TDSJ in the treatment of AS.

Abstract
The chronic inflammatory disease ankylosing spondylitis (AS) is marked by back discomfort, spinal ankylosis, and extra-articular symptoms. In AS, inflammation is responsible for both pain and spinal ankylosis. However, the processes that sustain chronic inflammation remain unknown. Despite the years of research conducted to decipher the intricacy of AS, little progress has been made in identifying the signaling events that lead to the development of this disease. T cells, an immune cell type that initiates and regulates the body's response to infection, have been established to substantially impact the development of AS. T lymphocytes are regarded as a crucial part of adaptive immunity for the control of the immune system. A highly coordinated interaction involving antigen-presenting cells (APCs) and T cells that regulate T cell activation constitutes an immunological synapse (IS). This first phase leads to the controlled trafficking of receptors and signaling mediators involved in folding endosomes to the cellular interface, which allows the transfer of information from T cells to APCs through IS formation. Discrimination of self and nonself antigen is somatically learned in adaptive immunity. In an autoimmune condition such as AS, there is a disturbance of self/nonself antigen discrimination; available findings imply that the IS plays a preeminent role in the adaptive immune response. In this paper, we provide insights into the genesis of AS by evaluating recent developments in the function of vesicular trafficking in IS formation and the targeted release of exosomes enriched microRNAs (miRNA) at the synaptic region in T cells.

Chronic Recurrent Multifocal Osteomyelitis (CRMO) and Juvenile Spondyloarthritis (JSpA): To What Extent Are They Related? J Clin Med 2023; 12:jcm12020453. [PMID: 36675382 PMCID: PMC9867437 DOI: 10.3390/jcm12020453] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2022] [Revised: 12/26/2022] [Accepted: 01/01/2023] [Indexed: 01/08/2023] Open
Abstract
Chronic recurrent multifocal osteomyelitis (CRMO) is an autoinflammatory disease occurring mainly in the pediatric age group (before 16 years) and generally presents as a separate entity. Synovitis, acne, pustulosis, hyperostosis and osteitis (SAPHO) syndrome combines osteoarticular and cutaneous involvement, similar to CRMO, and falls into the spectrum of spondyloarthritis (SpA). The fact that a patient can progress from one disease to another raises the question of whether CRMO, like SAPHO, could fall within the spectrum of SpA, ranging from a predominantly osteoarticular form to an enthesitic form with more or less marked skin involvement. In this review, we set out to discuss this hypothesis by highlighting the differences and similarities between CRMO and juvenile SpA in clinical, radiological and pathophysiological aspects. A common hypothesis could potentially consider intestinal dysbiosis as the origin of these different inflammatory diseases. Interindividual factors such as gender, environment, genetics and/or epigenetic background could act as combined disease modifiers. This is why we suggest that pathophysiology, rather than clinical phenotype, be used to reclassify these diseases.

Abstract
Purpose This study aimed to compare the changes in the expression of microRNA Let-7i in peripheral blood mononuclear cells (PBMCs) of patients with ankylosing spondylitis (AS) and the correlation between Let-7i and innate pro-inflammatory factors. It is necessary to search for a new biomarker to guide the prognosis of AS. Methods A total of 10 patients with AS and 10 healthy volunteers were selected as AS and control groups, respectively. The expression levels of Let-7i, Toll-like receptor 4 (TLR4), nuclear factor-κB (NF-κB), and interferon-gamma (IFN-γ) in PBMCs were detected by quantitative real-time polymerase chain reaction (qRT-PCR) and Western blotting (WB) to explore the relationship between Let-7i and pro-inflammatory factors. Furthermore, the relationship between Let-7i and TLR4 was determined by the luciferase reporter technology. Results The expression level of Let-7i in PBMCs of patients with AS was significantly lower than that of healthy control. The expression levels of TLR4, NF-κB, and IFN-γ in PBMCs derived from patients with AS were significantly higher than those of healthy control. The results show that Let-7i manipulation can regulate lipopolysaccharide (LPS)-induced TLR4 and IFN-γ expression in CD4+ T cells of patients with AS. The overexpression of Let-7i in T cells of patients with AS can suppress TLR4 and IFN-γ LPS-induced expression levels of cellular mRNA and protein. Let-7i can directly interfere TLR4-3'untranslated region (UTR) sequence and regulate the expression of the TLR4 gene in Jurkat T cells. Conclusion Let-7i may be involved in the pathogenesis of AS, and Let-7i expression in PBMCs may be helpful for the diagnosis and treatment of AS in the future.

Abstract
PURPOSE This review aims at investigating pathophysiological mechanisms in spondyloarthritis (SpA). Analysis of genetic factors, immunological pathways, and abnormalities of bone metabolism lay the foundations for a better understanding of development of the axial clinical manifestations in patients, allowing physician to choose the most appropriate therapeutic strategy in a more targeted manner. RECENT FINDINGS In addition to the contribution of MHC system, findings emerged about the role of non-HLA genes (as ERAP1 and 2, whose inhibition could represent a new therapeutic approach) and of epigenetic mechanisms that regulate the expression of genes involved in SpA pathogenesis. Increasing evidence of bone metabolism abnormalities secondary to the activation of immunological pathways suggests the development of various bone anomalies that are present in axSpA patients. SpA are a group of inflammatory diseases with a multifactorial origin, whose pathogenesis is linked to the genetic predisposition, the action of environmental risk factors, and the activation of immune response. It is now well known how bone metabolism leads to long-term structural damage via increased bone turnover, bone loss and osteoporosis, osteitis, erosions, osteosclerosis, and osteoproliferation. These effects can exist in the same patient over time or even simultaneously. Evidence suggests a cross relationship among innate immunity, autoimmunity, and bone remodeling in SpA, making treatment approach a challenge for rheumatologists. Specifically, treatment targets are consistently increasing as new drugs are upcoming. Both biological and targeted synthetic drugs are promising in terms of their efficacy and safety profile in patients affected by SpA.

Abstract
Ankylosing spondylitis (AS) is a common inflammatory spondyloarthritis affecting the spine and sacroiliac joint that finally results in sclerosis of the axial skeleton. Aside from human leukocyte antigen B27, transcriptomic biomarkers in blood for AS diagnosis still remain unknown. Hence, this study aimed to investigate credible AS-specific mRNA biomarkers from the whole blood of AS patients by analyzing an mRNA expression profile (GSE73754) downloaded Gene Expression Omnibus, which includes AS and healthy control blood samples. Weighted gene co-expression network analysis was performed and revealed three mRNA modules associated with AS. By performing gene set enrichment analysis, the functional annotations of these modules revealed immune biological processes that occur in AS. Several feature mRNAs were identified by analyzing the hubs of the protein-protein interaction network, which was based on the intersection between differentially expressed mRNAs and mRNA modules. A machine learning-based feature selection method, SVM-RFE, was used to further screen out 13 key feature mRNAs. After verifying by qPCR, IL17RA, Sqstm1, Picalm, Eif4e, Srrt, Lrrfip1, Synj1 and Cxcr6 were found to be significant for AS diagnosis. Among them, Cxcr6, IL17RA and Lrrfip1 were correlated with severity of AS symptoms. In conclusion, our findings provide a framework for identifying the key mRNAs in whole blood of AS that is conducive for the development of novel diagnostic markers for AS.

Abstract
Ankylosing spondylitis (AS) is a seronegative, chronic inflammatory arthritis with high genetic burden. A strong association with HLA-B27 has long been established, but to date its contribution to disease aetiology remains unresolved. Recent insights through genome wide studies reveal an increasing array of immunogenetic risk variants extraneous to the HLA complex in AS cohorts. These genetic traits build a complex profile of disease causality, highlighting several molecular pathways associated with the condition. This and other evidence strongly implicates T-cell-driven pathology, revolving around the T helper 17 cell subset as an important contributor to disease. This prominence of the T helper 17 cell subset has presented the opportunity for therapeutic intervention through inhibition of interleukins 17 and 23 which drive T helper 17 activity. While targeting of interleukin 17 has proven effective, this success has not been replicated with interleukin 23 inhibition in AS patients. Evidence points to significant genetic diversity between AS patients which may, in part, explain the observed refractoriness among a proportion of patients. In this review we discuss the impact of genetics on our understanding of AS and its relationship with closely linked pathologies. We further explore how genetics can be used in the development of therapeutics and as a tool to assist in the diagnosis and management of patients. This evidence indicates that genetic profiling should play a role in the clinician’s choice of therapy as part of a precision medicine strategy towards disease management.

Abstract
Autoimmune diseases, which affect approximately 5% of human population, are a range of diseases in which the immune response to self-antigens results in damage or dysfunction of tissues. Recent genome wide association studies (GWAS) have successfully identified novel autoimmune disease-associated loci, with many of them shared by multiple disease-associated pathways but much of the genetics and pathophysiological mechanisms remain still obscure. Considering that most of the potential causal variants are still unknown, many studies showed that the missense variant rs35667974 at interferon-induced with helicase C domain 1 (IFIH1) gene is protective for type 1 diabetes (T1D), psoriasis (PS) and psoriatic arthritis (PsA). Recently, this variant was found to be also associated with ankylosing spondylitis (AS), Crohn's disease (CD) and ulcerative colitis (UC). The IFIH1 gene encodes a cytoplasmic RNA helicase otherwise known as melanoma differentiation-associated 5 (MDA5) that recognizes viral RNA and is involved in innate immunity through recognition of viral RNA. In the present study we sought to investigate the association of the rare rs35667974 variant of IFIH1 gene, which resides in exon 14 and changes a conserved isoleucine at position #923 to valine, in the development of various autoimmune diseases and give a reason for the selectivity affecting different autoimmune diseases. Evolutionary studies and three-dimensional (3 D) homology modelling were employed on the MDA5 protein product, through its association with dsRNA, recognition factor controlling cytokine and chemokine signalling, to investigate the protective role of the MDA5 variant for certain autoimmune diseases.

Abstract
OBJECTIVES To identify biomarkers that reflect disease activity scores and to investigate the role of macrophage-associated chemokines in initial axial spondyloarthritis (axSpA). METHOD Patients with axSpA were enrolled. The SpondyloArthritis Research Consortium of Canada (SPARCC) method was used to score bone marrow oedema (BMO) in the inflammatory lesions on magnetic resonance imaging (MRI). Radiographic assessment of the spine was performed using the modified Stoke Ankylosing Spondylitis Spine Score (mSASSS). Clinical variables, including inflammatory markers, serum CC chemokine ligand 2 (CCL2), CCL3, CCL7, CCL8 and C-X3-C motif ligand 1 (CX3CL1), were measured. Correlation analysis between serum levels of these macrophage-associated chemokines and clinical data was performed. RESULTS There were no significant differences between the axSpA group and the healthy control group in terms of serum levels of CCL2, CCL3 or CCL8. Compared to the healthy control group, the serum levels of CCL7 and CX3CL1 were significantly higher in ankylosing spondylitis (AS) (p = 0.045, p = 0.017, respectively). In the AS subgroup, the serum level of CX3CL1 had a positive correlation with SPARCC scores. CONCLUSIONS In AS, serum CCL7 and CX3CL1 levels are elevated. The serum level of CX3CL1 is associated with MRI-determined oedema in AS. CX3CL1 may be useful as a biomarker to predict active inflammation in the sacroiliac joint (SIJ) in AS. Key Points • Serum levels of CX3CL1 are associated with MRI-determined oedema in AS. • CX3CL1 may be a useful biomarker to predict active inflammation in the sacroiliac joint in AS.

Abstract
Background Ankylosing spondylitis (AS) is a progressive rheumatic disease and studies reveal that the immune system is critical for the pathogenesis of AS. In the present study, various bioinformatics analysis methods were comprehensively applied, designed to identify potential key genes and inflammation states of AS. Methods The transcriptome profiles of GSE25101 and GSE73754 obtained from the Gene Expression Omnibus (GEO) database were merged for subsequent analyses. The differentially expressed genes (DEGs) were identified using the Bioconductor package Limma and threshold values. Functional enrichment and pathway enrichment analyses were performed using the clusterProfiler package and Gene Set Enrichment Analysis (GSEA). Next, protein-protein interaction (PPI) network of the identified DEGs was constructed by the online database, the Search Tool for the Retrieval of Interacting Genes (STRING), visualization and analysis were performed through Cytoscape software. Subsequently, we applied CIBERSORT algorithm to identify subpopulation proportions of immune cells in peripheral blood samples. Finally, we validated the hub genes with the GSE18781 dataset. Samples were collected from patients to validate gene and protein expression using qRT-PCR and ELISA. Results A total of 334 DEGs were identified, including 182 upregulated and 152 downregulated DEGs, between AS patients and normal human controls, which were primarily involved in immune response, autophagy, and natural killer cell-mediated cytotoxicity. The most prominent module and candidate biomarkers were identified from the PPI network. Biomarkers were selected for validation and their expressions were significantly decreased in peripheral blood samples which was consistent with transcriptome sequencing results. Nine genes with AUC > 0.70 were considered to be AS hub genes for ROC curve analysis, including GZMA, GZMK, PRF1, GNLY, NKG7, KLRB1, KLRD1, IL2RB and CD247. Furthermore, CIBERSORT results suggest that AS contained a higher proportion of CD8+ T cells, naive CD4+ T cells, neutrophils, and lower levels of gamma delta T cells compared with the normal controls. Conclusion In this study, we identified DEGs combined with their closely related biological functions and propose that granule-associated proteins and immune infiltration maybe involved in the progression of ankylosing spondylitis. These validated hub genes may provide new perspectives for understanding the molecular mechanisms of ankylosing spondylitis.

Abstract
Ankylosing spondylitis (AS) is a chronic autoimmune inflammatory disease that mainly affects the axial and sacroiliac joints. Single-nucleotide polymorphisms (SNPs) in genes encoding cytokines have been associated with AS, which can interfere with the production of these cytokines and contribute to the development of AS. In order to contribute to a better understanding of the pathology of AS, our objective was to investigate a possible association of the IL10 −1082 A>G SNP (rs1800896) with AS and to evaluate the serum levels of TNF-α, IL-10, IL-17A, and IL-17F in AS patients and controls comparing them with their respective genotypes (TNF rs1800629, IL10 rs1800896, IL17A rs2275913, and IL17F rs763780). Patients and controls were selected from the Maringá University Hospital and the Maringá Rheumatism Clinic, in Paraná State, Southern Brazil, and they were diagnosed by the ASAS Criteria. In total, 149 patients and 169 controls were genotyped for the IL10 −1082 A>G polymorphism using a polymerase chain reaction with sequence specific primers (PCR-SSP); the measurement of TNF-α serum levels was performed through the immunofluorimetric test and IL-10, IL-17A, and IL-17F using an ELISA test. There was a high frequency of the IL10 −1082 G allele in AS patients compared with controls with an odds ratio of 1.83 and 95% confidence interval of 1.32 to 2.54, and a significant difference in the genotype frequencies of the IL10 −1082 A/G+G/G between patients and healthy controls, with an odds ratio of 3.01 and 95% confidence interval of 1.75 to 5.17. In addition, increased serum levels of IL-10 were observed in AS patients: 2.38 (IQR, 0.91) pg/ml compared with controls 1.72 (IQR 0.93) pg/ml (P = 0.01). Our results also showed an association between IL17F rs763780 C/T+T/T genotypes and increased serum levels of IL-17F in patients with AS and also in controls. We can conclude that patients with the A/G and G/G genotypes for −1082 A>G (rs1800896) in the IL10 gene are three times more likely to develop AS, that the serum level of IL-10 was higher in AS patients and that the IL17F rs763780 polymorphism can affect the levels of IL-17F in the serum of patients and controls in the same way.

RAB5C, SYNJ1, and RNF19B promote male ankylosing spondylitis by regulating immune cell infiltration. ANNALS OF TRANSLATIONAL MEDICINE 2021; 9:1011. [PMID: 34277811 PMCID: PMC8267299 DOI: 10.21037/atm-21-2721] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/29/2021] [Accepted: 06/15/2021] [Indexed: 12/14/2022]
Abstract
Background This study aimed to identify the key genes related to male ankylosing spondylitis (AS) and to analyze the role of immune cell infiltration in the pathological process of this disease. Methods The AS dataset was downloaded from the Gene Expression Omnibus (GEO) public database, and the data of male healthy controls (M_HC) and male AS patients (M_AS) were extracted. R software was used to identify differentially expressed genes (DEGs). Functional and pathway enrichment analysis of the DEGs was performed. A protein-protein interaction (PPI) network was constructed, and the hub genes were screened out. All expression profile data were analyzed by weighted correlation network analysis (WGCNA) to screen out the hub genes, which were then intersected with the hub genes from the PPI network to obtain the key genes. Finally, the difference in immune cell infiltration in the two sets of samples was evaluated with CIBERSORT, and the correlation between the key genes and infiltrating immune cells was analyzed. Results A total of 689 DEGs were obtained, of which 395 genes were up-regulated and 294 genes were down-regulated. Functional and pathway enrichment analysis showed that DEGs were mainly enriched in pathways related to immune response. Based on the PPI analysis, five clusters with high scores were selected. Through WGCNA, 14 gene modules were obtained. The green module with the highest correlation was selected and intersected with the cluster previously obtained to obtain three key genes, RAB5C, SYNJ1, and RNF19B. Immune infiltration analysis found that monocytes and gamma delta T cells may be involved in the process of AS. Also, RAB5C, SYNJ1, and RNF19B are all related to increased levels of monocytes and macrophages. Conclusions RAB5C, SYNJ1, and RNF19B are key DEGs expressed in M_AS and may play a role in the disease’s occurrence and development through regulating immune cell functions.

Abstract
BACKGROUND Genetic polymorphisms in the endoplasmic reticulum aminopeptidase gene ERAP2 has been attributed with the etiopathogenesis of ankylosing spondylitis (AS). Here we assessed the association of ERAP2 gene single nucleotide polymorphisms (SNPs) with AS predisposition in Iranian patients and determined their effect on the inflammatory state of the patients. METHODS For genotyping of rs2548538, rs2287988, and rs17408150 SNPs using a real-time allelic discrimination approach, DNA was extracted from the whole blood of 250 AS patients and 250 healthy individuals. RNA of the peripheral blood mononuclear cells was separated, cDNA was synthesized, and transcriptional levels of cytokines, including interleukin (IL)-17A, IL-23, IL-10, and transforming growth factor-β, were measured. Enzyme-linked immunosorbent assay was used to measure the serum concentration on the cytokines. RESULTS Three ERAP2 gene SNPs were not associated significantly with AS risk. Nonetheless, rs2287988 and rs17408150 SNPs showed statistically significant association with susceptibility to the disease in those AS patients who were positive for human leukocyte antigen (HLA)-B27. Transcriptional level and serum concentration of IL-17A and IL-23 were higher, but those of IL-10 were lower in both AS patients and the HLA-B27-positive patient group relative to the control group. Nevertheless, ERAP2 gene SNPs in the HLA-B27-positive AS patients did not affect the transcription level and serum concentration of cytokines. CONCLUSIONS ERAP2 gene rs2287988 and rs17408150 SNPs are associated with susceptibility to AS, but they are probably not determining the levels of IL-17A, IL-23, and IL-10 in this disease.

Neutrophil extracellular traps and inflammatory response: Implications for the immunopathogenesis of ankylosing spondylitis. Int J Rheum Dis 2021; 24:426-433. [PMID: 33438309 DOI: 10.1111/1756-185x.14057] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2020] [Revised: 12/07/2020] [Accepted: 12/20/2020] [Indexed: 12/17/2022]
Abstract
AIM Ankylosing spondylitis (AS) pathogenesis has focused on the adaptive immune response; however, innate immune responses may also play a role in the inflammatory response of AS. Dysregulated neutrophil activation can induce tissue damage and contribute to the pathogenesis of immune-related diseases. Hence, the aim of this study was to assess the effect of immune complexes formed with the p30 of Salmonella typhimurium and anti-p30 antibodies present in the sera of AS patients and controls in inducing the release of neutrophil extracellular traps (NETs) and the secretion of pro-inflammatory cytokines. METHODS We collected polymorphonuclear leukocytes (PMNs) from healthy donors. The PMNs isolated were stimulated with p30 alone or in immunocomplexes formed with antibodies presents in sera of AS patients or control subjects. Then, the NETs were analyzed by fluorescence microscopy. Concentrations of interleukin (IL)-6, tumor necrosis factor (TNF)-α, IL-1β, IL-8 and IL-10, were determined using the Cytometric Bead Array kit. RESULTS Significant difference was observed in the release of NETs between the neutrophils stimulated with p30 + AS (70.52 ± 16.24) those unstimulated neutrophils (9.94 ± 12.12; P = .0095), stimulated with phorbol 12-myristate 13-acetate (39.78 ± 14.50; P = .0190), stimulated with control serum (CS) (10.85 ± 5.33; P = .0082) and serum of AS patient (10.28 ± 6.15; P = .0087). The stimulation of neutrophils with p30 alone induced a relatively low production of IL-6 (64.5 pg/mL), IL-8 (2658.3 pg/mL), IL-1β (31.11 pg/mL), and TNF-α (3.8 pg/mL), compared to p30 + AS and p30 + CS groups. CONCLUSION Our results show that neutrophils release NETs and pro-inflammatory cytokines in response to p30 in immunocomplexes. These findings could improve our understanding of the role of innate immunity in the initiation and/or maintenance of inflammatory responses, and in the progression of AS.

Abstract
A detailed understanding of the gene-regulatory network in ankylosing spondylitis (AS) is vital for elucidating the mechanisms of AS pathogenesis. Assaying transposase-accessible chromatin in single cell sequencing (scATAC-seq) is a suitable method for revealing such networks. Thus, scATAC-seq was applied to define the landscape of active regulatory DNA in AS. As a result, there was a significant change in the percent of CD8+ T cells in PBMCs, and 37 differentially accessible transcription factor (TF) motifs were identified. T cells, monocytes-1 and dendritic cells were found to be crucial for the IL-17 signaling pathway and TNF signaling pathway, since they had 73 potential target genes regulated by 8 TF motifs with decreased accessibility in AS. Moreover, natural killer cells were involved in AS by increasing the accessibility to TF motifs TEAD1 and JUN to induce cytokine-cytokine receptor interactions. In addition, CD4+ T cells and CD8+ T cells may be vital for altering host immune functions through increasing the accessibility of TF motifs NR1H4 and OLIG (OLIGI and OLIG2), respectively. These results explain clear gene regulatory variation in PBMCs from AS patients, providing a foundational framework for the study of personal regulomes and delivering insights into epigenetic therapy.

Punicalagin Exerts Protective Effects against Ankylosing Spondylitis by Regulating NF- κB-TH17/JAK2/STAT3 Signaling and Oxidative Stress. BIOMED RESEARCH INTERNATIONAL 2020; 2020:4918239. [PMID: 33029510 PMCID: PMC7532417 DOI: 10.1155/2020/4918239] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/26/2020] [Revised: 07/17/2020] [Accepted: 08/12/2020] [Indexed: 12/29/2022]
Abstract
Background Ankylosing spondylitis (AS) is a chronic inflammatory disease characterized by sacroiliitis and spinal rigidity of the axial joints. The role of oxidative stress and increased proinflammatory cytokines is well documented in AS pathogenesis. Punicalagin (2,3-hexahydroxydiphenoyl-gallagyl-D-glucose), an ellagitannin widely present in pomegranates, is found to exhibit potent anti-inflammatory, antiproliferative, and antioxidative effects. The present study was undertaken to investigate the effects of punicalagin in a rodent model of AS. Methods BALB/c mice induced spondylitis were sacrificed 24 h after the last injection of proteoglycan extract. Histological scoring was done to assess the degree of the disease. The expression of JAK2/STAT3 proteins and proteins of the nuclear factor-κB (NF-κB) pathway was determined by immunoblotting. Serum levels of inflammatory mediators—TNF-α, IL-1β, IL-6, IL-17A, and IL-23—were assessed. Levels of lipid peroxidation and reactive oxygen species (ROS) were quantified. Antioxidant status as a measure of activities of antioxidant enzymes—catalase (CAT), glutathione peroxidase (GPx), and superoxide dismutase (SOD)—was determined. Results Punicalagin effectively improved antioxidant status and decreased lipid peroxidation, ROS production, and serum levels of inflammatory mediators. NF-κB pathway and JAK2/STAT3 signaling were significantly (p < 0.05) downregulated. Punicalagin effectively regulated the production of cytokines by the Th17 cells and the IL-17A/IL-23 axis. Conclusion The observations suggest that punicalagin exerts a protective role in AS via reducing oxidative stress and regulating NF-κB/TH17/JAK2/STAT3 signal. Punicalagin thus could be explored further as a potent candidate compound in the treatment of AS.

Abstract
BACKGROUND Ankylosing spondylitis (AS) is a chronic inflammatory disease, whose pathogenesis is still unclear. Many studies show the proteins in extracellular vesicle (EVs) would change regularly in many diseases. The study aims to explore the proteins contents of serum-derived EVs in AS patients. METHODS EVs were separated by ExoQuickTM kit. The protein profiles of AS patients and healthy subjects were analyzed by Label-free-liquid chromatography mass spectrometry (LC-MS/MS) technology. Enzyme-linked immunosorbent assay (ELISA) was used to verify the levels of the differently expressed proteins. Receiver operation characteristic (ROC) curves and bioinformatic analysis were conducted. RESULTS Six hundred and ten serum-derived EVs proteins from AS patients were detected. Seventy-three diferentially expressed proteins were found in AS group, compared with healthy subjects. Of these, 31 proteins were up-regulated in AS group, while 42 proteins were down-regulated. ELISA result showed that EVs-derived serum amyloid A-1 (SAA1) was higher in AS group, which was consistent with the Label-free-LC-MS/MS data. ROC curves result revealed that the area under curve (AUC) value of EVs-derived SAA1 for AS was 0.768 (0.652-0.885). Bioinformatic analysis revealed that the differently expressed proteins in AS group were significantly involved in "complement and coagulation cascades", "staphylococcus aureus infection", "systemic lupus erythematosus" and "PI3K-Akt signaling pathway". CONCLUSIONS The protein profiles of serum-derived EVs in AS patients and healthy subjects were different. EVs-derived SAA1 may be a potential biomarkes of AS. The function analysis indicated that the differentially expressed proteins may potentially participate in immune response.

Copy number variation of IL17RA gene and its association with the ankylosing spondylitis risk in Iranian patients: a case-control study. BMC MEDICAL GENETICS 2020; 21:147. [PMID: 32650733 PMCID: PMC7350761 DOI: 10.1186/s12881-020-01078-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/31/2020] [Accepted: 06/25/2020] [Indexed: 12/11/2022]
Abstract
Background Ankylosing spondylitis (AS) is considered as a subtype of spondyloarthritis (SpA) that mainly leads to fatigue, stiffness, spinal ankylosis, and impaired physical functions with reduced quality of life. Interleukin (IL)-17A provokes additional inflammatory mediators and recruits immune cells to the inflamed site. IL17 expression increased in various inflammatory disorders including psoriasis, rheumatoid arthritis, multiple sclerosis, crohn’s disease, and ankylosing spondylitis. The current study aimed to evaluate the association of IL17RA copy number changes with the susceptibility to AS and their correlation to IL17RA expression in Iranian population. Methods IL17RA copy number genotyping assessments were carried out in 455 AS patients and 450 healthy controls, using custom TaqMan CNV assays. TaqMan primers and probe were located in Chr.22:17109553 based on pre-designed IL17RA Copy Number Assay ID, Hs02339506_cn. mRNA expression of IL17RA was also measured by SYBR Green real-time polymerase chain reaction (PCR). Results A IL17RA copy number loss (< 2) was associated with AS compared to 2 copies as reference (OR:2.18, 95% CI: (1.38–3.44), P-value < 0.001) and increased the risk of AS. IL17RA mRNA expression showed a significant increase in peripheral blood mononuclear cells (PBMCs) of all AS individuals than controls. The mRNA expression level of 2 copies was significantly higher in AS patients. Conclusions Our findings revealed that a low copy number of IL17RA might confer a susceptibility risk to AS. However, it is probably not directly involved in the regulation of IL17RA mRNA expression. Epigenetic mechanisms like DNA methylation, post-transcriptional, and -translational modifications that regulate the expression of the genes may contribute in upregulation of IL17RA mRNA expression in the loss of gene copy number condition.

Profiling and Bioinformatics Analysis of Differentially Expressed circRNAs in Spinal Ligament Tissues of Patients with Ankylosing Spondylitis. BIOMED RESEARCH INTERNATIONAL 2020; 2020:7165893. [PMID: 32626759 PMCID: PMC7313148 DOI: 10.1155/2020/7165893] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/03/2020] [Revised: 05/08/2020] [Accepted: 05/27/2020] [Indexed: 12/11/2022]
Abstract
Recent studies have reported that circular RNAs (circRNAs) play a crucial regulatory role in a variety of human diseases. However, the roles of circRNAs in ankylosing spondylitis (AS) remain unclear. In this study, we conducted circRNA expression profiling of the spinal ligament tissues of patients with AS by RNA sequencing (RNA-seq) and analyzed the potential functions of differentially expressed circRNA by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses to investigate the potential mechanisms associated with AS. The results showed that a total of 1,172 circRNAs were detected in the spinal ligament tissue samples, of which 123 circRNAs were significantly differentially expressed by a fold change ≥ 1.5 and p value < 0.05. Among these, 57 circRNAs were upregulated, and 66 were downregulated. GO and KEGG analyses demonstrated that the differentially expressed circRNAs were mainly involved in the regulation of biological processes of peptidyl-serine phosphorylation and human immune system that may be related to AS. In addition, the circRNA/miRNA interaction networks were established to predict the potential roles of differentially expressed circRNAs by bioinformatics analysis. Taken together, these results revealed the expression profiles of circRNAs and the potential functions of the differentially expressed circRNAs in the spinal ligament tissue of patients with AS, which may provide new clues for understanding the mechanisms associated with AS, and proceed to identify novel potential molecular targets for the diagnoses and treatment of AS.

Abstract
The development of inflammatory arthritis in patients receiving immune checkpoint inhibitor therapy is increasingly recognized due to the growing use of these drugs for the treatment of cancer. This represents an important opportunity not only to define the mechanisms responsible for the development of this immune-related adverse event and to ultimately predict or prevent its development, but also to provide a unique window into early events in the development of inflammatory arthritis. Knowledge gained through the study of this patient population, for which the inciting event is known, could shed light into the pathogenesis of autoimmune arthritis. This review will highlight the clinical and immunologic features of these entities to define common elements for future study.

Dose Response 2020; 18:1559325819901239. [PMID: 32009856 PMCID: PMC6974759 DOI: 10.1177/1559325819901239] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2019] [Revised: 12/10/2019] [Accepted: 12/19/2019] [Indexed: 12/12/2022] Open
Abstract
Objective: To explore the role of microRNA (miR-21) in new bone formation in ankylosing
spondylitis (AS) as mediated by different concentration of tumor necrosis
factor-α (TNF-α). Methods: Fibroblasts isolated from the hips of patients with AS were induced to
osteogenesis. These cells were then stimulated with varying concentrations
of TNF-α. MicroRNA-21 expressions were evaluated using reverse
transcription–polymerase chain reaction (RT-PCR) and osteogenesis was
detected via Alizarin Red S (ARS) staining and measurement of alkaline
phosphatase (ALP) activity. Relative expressions of p-STAT3, Nuclear STAT3,
cytoplasm STAT3, Runx2, BMP2, osteopontin, osteocalcin, and LC3B in AS
fibroblasts were measured after exposure to different concentrations of
TNF-α. The STAT3-inhibiting small interfering RNA allowed further
exploration on its impact on miR-21 and primary miR-21 expressions. A
proteoglycan-induced arthritis (PGIA) Balb/c mouse model was established in
order to monitor sacroiliac joint (SIJ) inflammation and subsequent damage
through magnetic resonance image. Serum miR-21 and TNF-α expressions were
evaluated using RT-PCR and enzyme-linked immunosorbent assay. At week 16,
mice models were transfected intravenously with miR-21 overexpressing agomir
and miR-21 inhibiting antagomir for 7 successive days. The rate of abnormal
bone formation at SIJ was evaluated using microcomputed tomography and
hematoxylin and eosin staining at week 24. Western blot analysis enabled
quantification of STAT-3, JAK-2, and interleukin (IL)-17A expressions
present in the SIJ. Results: The in vitro miR-21 expression and osteogenesis activity were noted to be
augmented in the setting of low TNF-α concentrations (0.01-0.1 ng/mL) while
they were depressed in settings with higher TNF-α concentrations (1-10
ng/mL). Samples with the most distinct ARS manifestation and ALP activity as
well as the highest miR-21 expressions were those who received 0.1 ng/mL of
TNF-α. Primary miR-21 was found to be notable raised by Si-STAT3, while the
converse effect was seen in mature miR-21 expressions. Intravenous injection
of exogenous miR-21 contributed to new bone formation and significantly
elevated expressions of STAT3, JAK2, and IL-17 in PGIA mice. Conclusions: The results revealed that miR-21 may act as a potential mediator between new
bone formation and inflammation in AS.

P2 receptors mRNA expression profiles in macrophages from ankylosing spondylitis patients and healthy individuals. Int J Rheum Dis 2019; 23:350-357. [PMID: 31884692 DOI: 10.1111/1756-185x.13783] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2019] [Revised: 12/02/2019] [Accepted: 12/06/2019] [Indexed: 12/19/2022]
Abstract
BACKGROUND Ankylosing spondylitis (AS) is a multifactorial rheumatic disease which mainly involves the axial skeleton. Macrophages and extracellular nucleotides have been shown to contribute to the inflammation process in autoimmune diseases. Membrane-bound purinergic P2 receptors might be involved in the modulation of immune cells in AS. Therefore, we aimed to analyze the messenger RNA (mRNA) expression of P2 receptors in the macrophages of AS patients and healthy controls. METHODS Twenty-three AS patients and 23 age- and sex-matched healthy individuals were included in our study. Whole blood-separated monocytes of study participants were stimulated by macrophage colony-stimulating factor for 7 days and differentiated to macrophages. Monocyte and macrophage markers were analyzed by flow cytometry. SYBR green real-time polymerase chain reaction was used to measure the relative expression levels of P2RX1 , P2RX2 , P2RX3 , P2RX4 , P2RX5 , P2RX6 , P2RX7 , P2RY1 , P2RY2 , P2RY4 , P2RY6 , P2RY11 , P2RY12 , P2RY13 , P2RY14 , and PANX1 genes. RESULTS P2RY13 and P2RY6 genes had the highest expression levels in macrophages among P2RY genes. P2RY1 mRNA expression was significantly down-regulated (-1.75 fold) and P2RY14 was up-regulated (2.6 fold) in macrophages of AS patients compared to healthy individuals. P2RX4 gene had the highest expression in monocyte-derived macrophages, followed by P2RX7 and P2RX1 genes. There was no significant difference in P2X receptor mRNA expression level between macrophages of AS patients and healthy individuals. CONCLUSIONS Our results indicate that AS patients show altered expression levels of P2 receptor genes. Moreover, these changes might be associated with disease activity and patients' status.

Evaluation of ERAP1 gene single nucleotide polymorphisms in immunomodulation of pro-inflammatory and anti-inflammatory cytokines profile in ankylosing spondylitis. Immunol Lett 2019; 217:31-38. [PMID: 31711818 DOI: 10.1016/j.imlet.2019.10.016] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2019] [Revised: 10/21/2019] [Accepted: 10/24/2019] [Indexed: 12/12/2022]
Abstract
BACKGROUND Ankylosing spondylitis (AS) is a prototype of chronic inflammatory arthritis termed seronegative spondyloarthropathies that typically affects the joints. Among the non-Human leukocyte antigen (HLA) loci, the strongest association has been observed with Endoplasmic reticulum aminopeptidase 1 (ERAP1) gene single nucleotide polymorphisms (SNPs). Moreover, the effect of ERAP1 gene SNPs on the pro-inflammatory and anti-inflammatory cytokines in AS disease has still been poorly elucidated. In this study, we aimed to determine the association of ERAP1 gene SNPs (rs30187 and rs2287987) with AS risk as well as their effect on the mRNA expression of pro-inflammatory and anti-inflammatory cytokines, with emphasis on the immunoregulation of the IL-17/IL-23 pathway, in an Iranian population. METHODS We performed Single specific primer (SSP)-PCR for genotyping of 160 AS patients and 160 healthy controls. After isolation of peripheral blood mononuclear cells (PBMCs), total RNA of PBMCs was isolated, complementary DNA (cDNA) was synthesized, and quantitative analyses of mRNA expression of cytokines were performed by Real-time PCR for 40 HLA-B27 positive AS patients and 40 healthy individuals as controls. RESULTS It was seen that T allele of rs30187 (OR = 1.54, 95% CI = 1.07-2.22, P = 0.017) and C allele of rs2287987 (OR 1.50, 95% CI 1.05-2.14, P = 0.024) were associated with the risk of AS. Both of these alleles were associated more strongly in the HLA-B27 positive AS patients. There was a significant overexpression of mRNAs of pro-inflammatory (IL-17A, IL-17F, IL-23, TNF-α and IFN-γ), while downregulation of anti-inflammatory cytokines (IL-10 and TGF-β) in PBMCs from 40 HLA-B27 positive AS patients in comparison to controls. AS patients with rs30187 SNP TT genotype expressed mRNA of IL-17A, IL-17F, and IL-23 significantly higher than patents with CT and CC genotypes for this SNP. CONCLUSIONS This study represented the association of ERAP1 gene rs30187 and rs2287987 polymorphism with the risk of AS. Additionally, it appears that rs30187 polymorphism may be involved in the immunomodulation of the IL-17/IL-23 pathway in the AS disease.

Abstract
Spondyloarthritis (SpA) comprises multifactorial diseases characterized by a complex interplay between an inherited background and environmental factors that lead to immune response dysregulation and inflammation. Unlike for other rheumatic diseases, no specific biomarkers are available in clinical practice for diagnosing SpA. The aim of the present study was to search new potential biomarkers for SpA diagnosis by focusing on the innate immune response. An evaluation was made of the mRNA expression levels of inflammatory cytokines (TNF-α, IL-1β, TGF-β1, S100A8, S100A9) and matrix metalloproteinases (MMP3, MMP8, MMP9) in blood mononuclear cells of SpA patients (n = 64) with respect to controls (n = 100). In parallel, the pattern of intracellular calcium flows of blood monocytes was verified in order to ascertain whether any specific fingerprint characterizes innate immune cells in SpA patients. Inflammatory cytokines and MMPs expression levels were not correlated with SpA, while in this disease a reduced expression of the S100A8 and a decreased frequency of monocytes showing intracellular calcium flows were observed. In conclusion, no specific signs of systemic inflammation are detectable in SpA, but the disease affects the "on-off" mechanisms that regulate the concentration of intracellular calcium and calcium-related proteins. This potentially pave the way for the discovery of new biomarkers.

Abstract
Introduction: Ankylosing spondylitis (AS) and Behçet’s disease are known to be associated with the human leukocyte antigen (HLA)-B27 and HLA-B51 genes, respectively. However, many of their clinical findings―including articular and extra-articular symptoms―are similar, making diagnosis a challenge in the early stage of the disease. The aim of this study was to investigate the differences in clinical findings of AS patients with and without the HLA-B27 gene. Materials and Methods: We performed a retrospective chart review of 151 AS patients. The following clinical findings were evaluated: oral ulcer, genital ulcer, skin manifestation, uveitis, peripheral arthritis; and gastrointestinal, cardiac and pulmonary involvement. Patients were divided into 4 groups based on absence or presence of the HLA-B27 and HLA-B51 genes. The number of patients with each clinical finding was subsequently examined in each group. Results: The incidence of uveitis was significantly higher in the HLA-B27-positive group (P = 0.004); however, other clinical findings did not differ significantly according to the absence or presence of the HLA-B27 gene. There were no significant differences in the clinical findings of patients with positive and negative HLA-B51. Conclusion: HLA-B27 was associated with the development of uveitis but not with other clinical findings or disease activity in AS patients. HLA-B51 was not associated with the clinical findings or disease activity of AS.

Abstract
Objectives: The aim of the present study was to investigate the differences in clinic-pathological features of secondary IgA nephropathy (SIgAN) between patients with ankylosing spondylitis (AS) and rheumatoid arthritis (RA).Methods: Forty-six patients with SIgAN related to AS (SIgAN-AS) and 26 patients with SIgAN related to RA (SIgAN-RA) were enrolled in this retrospective study. The two groups were compared for their clinic-pathological characteristics.Results: The 10-year prevalence of SIgAN-AS and SIgAN-RA were 167 per 1000 and 51.3 per 1000, respectively. Compared with SIgAN-RA patients, SIgAN-AS patients had lower incidences of edema and nephrotic syndrome, but higher levels of eGFR, serum C3, and CD3- and CD8-positive T-cell counts, but less incidences of acute tubulointerstitial lesions and interlobular arterial lesions. IgM was the most familiar co-depositing immune complex on tissue with significantly different frequencies. In SIgAN-AS patients, those with positive HLA-B27 presented with lower levels of proteinuria, higher levels of serum IgG and C3, and less incidence of renal insufficiency, crescents >14.5%, glomerular sclerosis >32.6% and segmental sclerosis >5.2%.Conclusion: SIgAN was more prevalent in AS than in RA. SIgAN-AS patients differed from SIgAN-RA patients in certain clinic-pathological characteristics. HLA-B27 likely protected SIgAN-AS patients from renal insufficiency.

Abstract
This study was conducted to clarify the associations of tumor necrosis factor-α induced protein 3 (TNFAIP3) and TNFAIP3-interacting protein 1 (TNIP1) genetic polymorphisms with ankylosing spondylitis (AS) susceptibility. Five single nucleotide polymorphisms (SNPs) in TNFAIP3 gene and four in TNIP1 gene were genotyped in 667 AS patients and 667 matched healthy controls. Genotypes and haplotype analysis were conducted by using SPSS 23.0 and Haploview 4.2 software. The T allele and CT genotype in TNFAIP3 rs10499194 were significantly associated with a reduced AS risk (T allele vs. C allele, OR = 0.619, 95% CI = 0.430–0.889, P = 0.009; CT vs. CC, OR = 0.603, 95% CI = 0.416–0.875, P = 0.007). However, no association remained significant after Bonferroni correction. The rs13207033A- rs10499194T haplotype of TNFAIP3 conferred a protective effect on AS susceptibility. Stratification analyses suggested that rs10499194 polymorphism decreased the risk of AS in the male subgroup, subgroup aged ≥ 29, HLA-B27 positive subgroup as well as the subgroups of BASFI < 4 and BASDAI < 4 (all P < 0.05). Furthermore, the functional annotation suggested a potential function of rs10499194 mutation. Our results demonstrated that TNFAIP3 rs10499194 polymorphism may be associated with a reduced risk of AS.

Abstract
BACKGROUND Copy number variation (CNV) of DNA segments has been considered as an important component of genetic variation, affecting the quality and quantity of gene expression. Bone morphogenic protein 8A (BMP8A) has been reported to function in bone formation. With respect to the bone and joint complications in ankylosing spondylitis (AS), this investigation aimed to study the role of BMP8A gene CNV in impressing the gene expression as well as the disease risk. METHODS A total of 900 individuals, including 450 patients with AS and 450 healthy controls were enrolled. The copy numbers of BMP8A gene were detected by TaqMan real-time polymerase chain reaction (PCR) method. BMP8A messenger RNA (mRNA) transcript level in peripheral blood mononuclear cells (PBMCs) was also measured by SYBR Green real-time gene expression PCR method. RESULTS No significant association of BMP8A copy number was detected with the risk of AS. BMP8A mRNA expression level was significantly downregulated in patients compared with controls. mRNA expression level of BMP8A in both AS patients with and without syndesmophyte was significantly lower than the healthy control group. There was no correlation between the mRNA expression level of BMP8A and both demographic and clinical data of the patients. CONCLUSIONS Although BMP8A gene expression was downregulated in patients with AS, its copy number could not affect the transcript level of BMP8A gene in PBMCs and was not associated with susceptibility to AS in Iranian population. BMP8a may take into account as an indicator of bone formation process in AS, but it seems that mechanisms other than CNV may regulate this protein.

Abstract
INTRODUCTION Most arthritides are associated with pain and psychological distress (clinically significant depression and anxiety). Pain and depression are mutually exacerbating; both may continue even when joint involvement appears well controlled. Area covered: There is strong evidence that arthritis-related stress impacts the central nervous system and, together with peripheral inflammatory changes, can cause central sensitization that can lead to chronic pain and worsening of affective distress. Cytokines and chemokines participate both in joint inflammation and in central sensitization. We review evidence of these relationships in five arthritides, namely rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, gout, and in osteoarthritis of the hips and knees. Central sensitization in these conditions results in long-lasting pain and psychological distress. Expert commentary: Chronic pain and depression are important but often neglected in the clinical assessment and treatment of arthritis. The potential role of biologic cytokines and Janus kinase inhibitors in dealing with these symptoms needs further study.

Susceptibility to ERAP1 gene single nucleotide polymorphism modulates the inflammatory cytokine setting in ankylosing spondylitis. Int J Rheum Dis 2019; 22:715-724. [PMID: 30740926 DOI: 10.1111/1756-185x.13494] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2018] [Revised: 12/26/2018] [Accepted: 01/04/2019] [Indexed: 11/28/2022]
Abstract
AIM To evaluate the association of ERAP1 gene single nucleotide polymorphisms (SNPs) with the risk of ankylosing spondylitis (AS) and their role in modulation of the inflammatory interleukin (IL)-17/IL-23 axis in the disease. METHODS For genotyping, 190 AS cases and 190 healthy controls were enrolled. After DNA extraction, all the subjects were genotyped for rs17482078, rs469876, and rs27038 polymorphisms using single specific primer polymerase chain reaction (PCR) assay. After isolation of peripheral blood mononuclear cells, RNA extraction and complementary DNA synthesis, real-time PCR using SYBR Green master mix was employed to determine messenger RNA (mRNA) expression of IL-17A and IL-23 in PBMCs. Using enzyme-linked immunosorbent assay, the concentration of these cytokines was determined in serum samples. RESULTS It was observed that the A allele of rs27038 polymorphism significantly increased AS risk (odds ratio [OR] = 1.53, 95% CI =1.11-2.12; P = 0.0096). Moreover, AA and AG genotypes of this SNP were associated with increased (OR = 2.89, 95% CI = 1.42-5.85; P = 0.0031) and decreased (OR = 0.57, 95% CI = 0.36-0.92; P = 0.021), respectively, risk of the disease. The rs27038 SNP was associated with C-reactive protein level. There were significantly increased mRNA and serum concentrations of both IL-17A and IL-23 in AS patients compared with controls. Furthermore, AS patients with the AA in comparison to other genotypes for rs27038 SNP indicated significantly increased mRNA and serum concentration levels for both cytokines. CONCLUSIONS This study demonstrated the association of ERAP1 gene rs27038 polymorphism with the risk of AS in an Iranian population. Additionally, it seems that rs27038 is involved in the modulation of the inflammatory IL-17/IL-23 axis in AS.

Association analysis of ERAP1 gene single nucleotide polymorphism in susceptibility to ankylosing spondylitis in Iranian population. Immunol Lett 2018; 201:52-58. [PMID: 30412714 DOI: 10.1016/j.imlet.2018.11.002] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2018] [Revised: 10/26/2018] [Accepted: 11/05/2018] [Indexed: 12/18/2022]
Abstract
Background Ankylosing spondylitis (AS) is a debilitating spondyloarthropathy that has been associated with variation in several genes. Human leukocyte antigen (HLA)-B27 constructs an impaired structure, culminating in recognition and activation of immune system. Impaired function of Endoplasmic reticulum aminopeptidase (ERAP) 1, which primes peptides to be loaded in HLA molecules, has strongly been associated with AS proneness. Here, we intended to investigate the possible association of ERAP1 gene single nucleotide polymorphisms (SNPs) with AS susceptibility in Iranian patients. Methods Two-hundred and twenty AS patients and 220 healthy controls were enrolled in this study. DNA was extracted from blood samples and then was genotyped for rs27044, rs17482078, and rs10050860 polymorphism by SSP-PCR approach. Results It was seen that G allele and GG genotype of rs27044 SNP significantly increased the risk of AS that was even stronger in HLA-B27 positive patients. Moreover, the T allele and TT genotype of rs10050860 polymorphism were associated with increased risk of the disease in both all and HLA-B27 positive AS group. Two haplotypes were associated with the risk of AS and there was linkage disequilibrium between SNPs. Two SNPs were associated with clinicopathological manifestations of AS subjects. Conclusions This association study replicated the role ofERAP1 gene polymorphisms with the risk of AS in an Iranian population.

Int J Rheum Dis 2018; 21:1746-1755. [PMID: 30398028 DOI: 10.1111/1756-185x.13408] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2017] [Revised: 08/03/2018] [Accepted: 09/14/2018] [Indexed: 02/05/2023]
Abstract
BACKGROUND Several genetic studies have assessed the association between polymorphisms in killer immunoglobulin-like receptors (KIR) genes and susceptibility of individuals to ankylosing spondylitis (AS), but the findings have been inconclusive and incongruous. Therefore, we conducted this meta-analysis of all case-control studies meeting the inclusion criteria for obtaining an exact conclusion of the effect of KIR polymorphisms on the risk of AS. METHODS A systematic literature search was conducted in electronic databases, including Scopus web of science, ScienceDirect, and PubMed to find all eligible studies exploring the association between KIR polymorphisms and the risk of AS, prior to June 2017. Pooled odds ratios (OR) and their corresponding 95% CIs were used to evaluate the strength of the association between KIR polymorphisms and the risk of AS. RESULTS A total of 16 case-control studies, encompassed in 12 papers, with 1770 cases and 2907 healthy subjects were included in the meta-analysis. This meta-analysis revealed three significant positive associations of 2DS1, 2DS5, and 3DS1 with susceptibility to AS, while two significant negative associations of 2DL2 and 2DS2 with susceptibility to AS were identified. In the subgroup analysis based on human leukocyte antigen (HLA)-B*27 positive patients and healthy subjects, results indicated that there were four significant positive associations between 2DL5, 2DS4, 2DS5, 3DS1 polymorphisms and susceptibility to AS in HLA-B*27-positive patients; a significant negative association of 3DL1 in HLA-B*27-positive patients was found. CONCLUSIONS While 2DS1, 2DS5, and 3DS1 polymorphisms increased AS risk, 2DL2 and 2DS2 polymorphisms were associated with reduced AS susceptibility.
