Yu HC, Wang ST, Lu MC. Dysregulated Non-Coding RNA Expression in T Cells from Patients with Ankylosing Spondylitis Contributes to Its Immunopathogenesis. Biomedicines 2024; 12:1873. [PMID: 39200337 PMCID: PMC11351219 DOI: 10.3390/biomedicines12081873] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2024] [Revised: 08/12/2024] [Accepted: 08/14/2024] [Indexed: 09/02/2024] Open
Abstract
Ankylosing spondylitis (AS) is a chronic inflammatory disorder characterized by inflammatory back pain and bony fusion of vertebral joints. Genetic associations and environmental factors have been proposed to explain the immunopathogenesis of AS. In the past few years, there have been major advances in understanding T cell dysfunction in AS. Clinically, targeting interleukin-17A, a major cytokine secreted by T helper 17 cells, has been approved for treating patients with active AS. Non-coding RNAs (ncRNAs) are RNA transcripts that do not translate into proteins. The ncRNAs regulate both innate and adaptive immunity and participate in the pathogenesis of autoimmune diseases, including AS. The main purpose of this article is to review the up-to-date studies investigating the aberrant expression of ncRNAs in T cells from patients with AS and to summarize their roles in its pathogenesis. After searching PubMed for studies published between January 2013 and June 2024, nine studies investigating the expression of ncRNAs in AS T cells were included. We found that aberrantly expressed ncRNAs in AS T cells could cause abnormal cytokine release, cell signaling abnormalities, and dysregulated cell proliferation and death, which contribute to the immunopathogenesis of AS. We discussed some limitations of these studies and suggested several research fields for further investigation.

Int J Immunogenet 2024; 51:143-148. [PMID: 38468428 DOI: 10.1111/iji.12659] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Revised: 01/24/2024] [Accepted: 02/06/2024] [Indexed: 03/13/2024]
Abstract
Genome-wide association studies analysis has revealed associations between ankylosing spondylitis (AS) and loci on the TBX21 gene across various populations. This study aimed to investigate if there is a connection between a higher risk of AS in a Chinese population and two polymorphism loci on the TBX21 gene. To achieve this, we performed a case-control investigation involving 363 patients with AS and 907 healthy individuals. Genotyping was carried out using the iPLEX Gold genotyping assay. The analysis of genotypes and haplotypes was performed using SPSS 23.0 and SHEsis software. The results revealed no statistically significant correlation between the two specified single-nucleotide polymorphisms of TBX21 (rs11657479 C/T and rs4794067 C/T) and susceptibility to AS. However, upon conducting stratification analysis, our findings demonstrated a significant association between rs11657479 and susceptibility to human leucocyte antigen (HLA)-B27+ AS in allelic (C vs. T: odds ratio [OR] = 1.52, 95%CI = 1.09-2.11, corrected p [pc] = .028), heterozygous (CT vs. TT: OR = 1.63, 95%CI = 1.13-2.34, pc = .016) and dominant (CT + CC vs. TT: OR = 1.60, 95%CI = 1.12-2.28, pc = .018) models. Furthermore, the haplotype rs4794067/C-rs11657479/C of TBX21 was found to increase the risk of HLA-B27+ AS cases. In conclusion, our findings indicate a correlation between TBX21 gene polymorphism and HLA-B27+ AS patients within the Chinese population.

Abstract
BACKGROUND Ankylosing spondylitis (AS) is one of the most common immune-mediated arthritic diseases worldwide. Despite considerable efforts to elucidate its pathogenesis, the molecular mechanisms underlying AS are still not fully understood. METHODS To identify candidate genes involved in AS progression, the researchers downloaded the microarray dataset GSE25101 from the Gene Expression Omnibus (GEO) database. They identified differentially expressed genes (DEGs) and functionally enriched them for analysis. They also constructed a protein-protein interaction network (PPI) using STRING and performed cytoHubba modular analysis, immune cell and immune function analysis, functional analysis and drug prediction.The results showed that DEGs were mainly associated with histone modifications, chromatin organisation, transcriptional coregulator activity, transcriptional co-activator activity, histone acetyltransferase complexes and protein acetyltransferase complexes. RESULTS The researchers analysed the differences in expression between the CONTROL and TREAT groups in terms of immunity to determine their effect on TNF-α secretion. By obtaining hub genes, they predicted two therapeutic agents, AY 11-7082 and myricetin. CONCLUSION The DEGs, hub genes and predicted drugs identified in this study contribute to our understanding of the molecular mechanisms underlying the onset and progression of AS. They also provide candidate targets for the diagnosis and treatment of AS.

Abstract
Copy number variations (CNVs) in TBX21 gene have been reported to be significantly and positively correlated with acute anterior uveitis (AAU). Our study was performed to further determine whether single nucleotide polymorphisms (SNPs) in TBX21 gene confer susceptibility to AAU in a Chinese population. In our case-control study, 420 AAU patients and 918 healthy controls were included. SNP genotyping was conducted via the MassARRAY™ iPLEX Gold platform. Association and haplotype analyses were performed via SPSS 23.0 and SHEsis software. No significant association was observed between two candidate SNPs of TBX21 gene (rs4794067, rs11657479) and susceptibility to AAU (Pc > 0.05). In stratification analysis, the result also showed no significant difference between the HLA-B27 positive AAU patients and non-typed healthy controls. Additionally, no association was detected between TBX21 haplotypes and AAU risk. In conclusion, the polymorphisms rs4794067 and rs11657479 in TBX21 gene did not confer disease susceptibility to AAU in a Chinese population.

Abstract
Background The pathogenesis of ankylosing spondylitis (AS) is still not clear, and immune-related genes have not been systematically explored in AS. The purpose of this paper was to identify the potential early biomarkers most related to immunity in AS and develop a predictive disease risk model with bioinformatic methods and the Gene Expression Omnibus database (GEO) to improve diagnostic and therapeutic efficiency. Methods To identify differentially expressed genes and create a gene coexpression network between AS and healthy samples, we downloaded the AS-related datasets GSE25101 and GSE73754 from the GEO database and employed weighted gene coexpression network analysis (WGCNA). We used the GSVA, GSEABase, limma, ggpubr, and reshape2 packages to score immune data and investigated the links between immune cells and immunological functions by using single-sample gene set enrichment analysis (ssGSEA). The value of the core gene set and constructed model for early AS diagnosis was investigated by using receiver operating characteristic (ROC) curve analysis. Results Biological function and immune score analyses identified central genes related to immunity, key immune cells, key related pathways, gene modules, and the coexpression network in AS. Granulysin (GNLY), Granulysin (GZMK), CX3CR1, IL2RB, dysferlin (DYSF), and S100A12 may participate in AS development through NK cells, CD8+ T cells, Th1 cells, and other immune cells and represent potential biomarkers for the early diagnosis of AS occurrence and progression. Furthermore, the T cell coinhibitory pathway may be involved in AS pathogenesis. Conclusion The AS disease risk model constructed based on immune-related genes can guide clinical diagnosis and treatment and may help in the development of personalized immunotherapy.

Clin Rheumatol 2022; 41:2403-2416. [PMID: 35420296 PMCID: PMC9287221 DOI: 10.1007/s10067-022-06137-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2021] [Revised: 02/11/2022] [Accepted: 03/19/2022] [Indexed: 12/15/2022]
Abstract
OBJECTIVE IL-35 is a potent immunosuppressive and anti-inflammatory cytokine, consisting of a p35 subunit and an Epstein-Barr virus-induced gene 3 (EBI3) subunit, which suppresses CD4+ effector T cell proliferation and promotes regulatory T cell (Treg) expansion. However, the effects of IL-35 on regulatory B cells (Bregs) in ankylosing spondylitis (AS) have not been explored. The present study aimed (i) to measure serum IL-35 levels and the percentages of Bregs in the peripheral blood of patients with AS and (ii) to explore their relationships in the pathogenesis of AS. METHODS A total of 77 patients with AS (AS group), including 47 inactive AS and 30 active AS cases, and 59 healthy controls (HCs) were enrolled into this study. The serum levels of IL-35 and IL-10 were detected by ELISA, and the mRNA levels of p35 and EBI3 were measured by RT-qPCR. The percentages of CD19+CD24hiCD38hi and CD19+CD24hiCD27+ Bregs and IL-35 receptor (IL-12Rβ2, IL-27Rα and gp130), IL-10, p-STAT1, p-STAT3, and p-STAT4 in CD19+ B cells were detected by flow cytometry. The correlations between IL-35 levels and percentages of Bregs were analyzed by determining Pearson's correlation coefficient. The effect of IL-35 on Bregs was determined by mix-culture of recombinant (r) IL-35 with peripheral blood mononuclear cells (PBMCs). RESULTS The serum IL-35 and IL-10 levels, p35 and EBI3 mRNA levels, and the percentages of CD19+CD24hiCD38hi and CD19+CD24hiCD27+ Bregs were significantly lower in AS patients than those in HCs. In addition, the percentages of CD19+CD24hiCD38hi and CD19+CD24hiCD27+ Bregs in active AS patients were significantly lower than those in inactive AS patients. The serum IL-35 levels were positively correlated with the percentages of CD19+CD24hiCD38hi and CD19+CD24hiCD27+ Bregs in AS patients. IL-12Rβ2 and IL-27Rα, but not gp130 subunit, were expressed in CD19+ B cells in AS patients. RIL-35 could effectively promote CD19+CD24hiCD38hi Breg expansion and IL-10 production. Meanwhile, rIL-35 also promoted the expression of IL-12Rβ2 and IL-27Rα and the phosphorylation of STAT1 and STAT3 in CD19+ B cells. CONCLUSION These results demonstrated that reduced IL-35 production may be associated with Bregs defects in AS patients. RIL-35 induced the proliferation of CD19+CD24hiCD38hi Bregs and IL-10 production, suggesting that IL-35 may serve as a reference for further investigation to develop novel treatments for AS. Key Points • Our study investigated the effects of IL-35 on Bregs in AS patients. • We found the serum IL-35, IL-10 levels, and the percentages of CD19+CD24hiCD38hi and CD19+CD24hiCD27+ Bregs were significantly lower in AS patients. • The serum IL-35 levels were positively correlated with the percentages of CD19+CD24hiCD38hi and CD19+CD24hiCD27+ Bregs in AS patients. • Recombinant IL-35 could effectively promote CD19+CD24hiCD38hi Breg expansion and IL-10 production.

Abstract
The domination of pro-inflammatory Th subsets (Th1, Th17) is characteristic of ankylosing spondylitis (AS). Mesenchymal stem cells (MSC) were reported to normalize Th imbalance, but whether MSCs from AS adipose tissue (AS/ASCs) possess such properties is unknown. We examined AS/ASCs' impact on Th-cell differentiation, using healthy donors ASCs (HD/ASCs) as a control. The assessment of the expression of transcription factors defining Th1 (T-bet), Th2 (GATA3), Th17 (RORc), and Treg (FoxP3) subsets by quantitative RT-PCR, the concentrations of subset-specific cytokines by ELISA, and Treg (CD4+CD25highFoxP3+) formation by flow cytometry, were performed in the co-cultures of ASCs with activated CD4+ T cells or peripheral blood mononuclear cells (PBMCs). AS/ASCs and HD/ASCs exerted similar immunomodulatory effects. Acting directly on CD4+ T cells, ASCs decreased the T-bet/GATA3 and RORc/FoxP3 ratios, diminished Treg formation, but increase IFNγ and IL-17AF production, while ASCs co-cultured with PBMCs enhanced Treg generation and reduced IFNγ release. ASCs failed to up-regulate the anti-inflammatory IL-10 and TGFβ. AS/ASCs' impact on allogeneic and autologous PBMCs was similar. In conclusion, to shift Th differentiation to a functional anti-inflammatory direction, ASCs require accessory cell support, whereas their direct effect may be pro-inflammatory. Because ASCs neither inhibit IL-17AF nor up-regulate anti-inflammatory cytokines, their usefulness for AS patients' treatment remains uncertain.

Abstract
Background Ankylosing spondylitis (AS) is a common form of inflammatory arthritis. Micheliolide (MCL), a sesquiterpene lactone, is reportedly involved in the alleviation of inflammatory response. This study aimed to investigate the mechanism of MCL in the treatment of AS. Methods Mice were randomly divided into five groups: the sham group, the MCL (50 mg/kg) group, the AS model group, the AS + MCL (20 mg/kg) group, and the AS + MCL (50 mg/kg) group. After the addition of the inhibitor celastrol, mice were randomly divided into five groups: the sham group, the AS model group, the AS + MCL (50 mg/kg) group, the AS + Celastrol (1 mg/kg) group, and the AS + Celastrol (1 mg/kg) + MCL (50 mg/kg) group. Results Compared with the AS model mice, the protein expression levels of tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, IL-6, and IL-18 were decreased after MCL treatment. The protein expression levels of capase-1 p10, IL-1β p17, NOD-like receptor family and pyrin domain containing 3 (NLRP3), caspase-1, and apoptosis-associated speck-like protein (ASC) were also reduced. The protein expression levels of Interferon (IFN)-γ were down-regulated, but levels of IL-4 were increased. Western blotting and immunohistochemistry revealed that the levels of p-IκB α were up-regulated, while the levels of phosphorylated-p65 were down-regulated. After the addition of celastrol, MCL treatment significantly reduced the levels of p-p65, NLRP3, caspase-1, and ASC. Meanwhile, the levels of IFN-γ were markedly down-regulated, but the levels of IL-4 were enhanced. Conclusions Our study found that MCL suppressed the activation of NLRP3 inflammasome and maintained the balance of Th1/Th2 via regulating NF-κB signaling. Therefore, MCL could potentially be used to treat AS.

BACKGROUND This study was to investigate the value of 10 serum inflammatory cytokines for predicting clinical response to celecoxib in ankylosing spondylitis (AS) patients. METHODS Totally, 103 active AS patients who underwent celecoxib treatment for 12 weeks were enrolled. Then, pre-treatment serum TNF-α, IL-1β, IL-6, IL-8, IL-17A, IL-21, IL-23, IL-32, ICAM-1, and VEGF were detected by enzyme-linked immunosorbent assay. Besides, the ASAS 20 response was assessed at week 2 (W2), week 6 (W6), and week 12 (W12). Based on the ASAS 20 response at W12, patients were divided into responders and non-responders. RESULTS After celecoxib treatment, 53 (51.3%), 58 (56.3%), and 60 (58.3%) patients achieved ASAS 20 response at W2, W6, and W12, respectively. Furthermore, IL-1β (P = 0.019), IL-6 (P = 0.004), and IL-17A (P = 0.007) levels were higher, while TNF-α (P = 0.086), IL-8 (P = 0.143), IL-21 (P = 0.687), IL-23 (P = 0.329), IL-32 (P = 0.216), ICAM-1 (P = 0.119), and VEGF (P = 0.732) levels were similar in responders compared with non-responders. Subsequent multivariate logistic regression analysis revealed that among these inflammatory cytokines, only IL-6 (P = 0.019) independently predicted higher ASAS 20 response to celecoxib at W12, and it had a fair value for predicting ASAS 20 response to celecoxib at W12 (area under the curve: 0.666, 95% confidence interval: 0.561-0.771) by receiver-operating characteristic curve analysis. CONCLUSION Serum IL-1β, IL-6, and IL-17A serve as indicators for predicting clinical response to celecoxib in AS patients, which may assist with the optimization of personalized treatment.

Abstract
Rheumatism is a group of diseases, most of which are autoimmune diseases, that violate joints, bones, muscles, blood vessels and related soft tissue. As is well known, cytokines play a role in the pathogenesis of several rheumatic diseases, such as rheumatoid arthritis, spondyloarthritides, and systemic lupus erythematosus. Recently, the role of interleukin-4 (IL-4), which may participate in the mechanism of rheumatism, have been discovered. It is reported that IL-4 takes part in the regulation of T cell activation, differentiation, proliferation, and survival of different T cell types. IL-4 also has an immunomodulatory effect on B cells, mast cells, macrophages, and many cell types. A review of the literature on functions of IL-4 in rheumatic diseases is presented.
