[PMID: 38525269 PMCID: PMC10959653 DOI: 10.1016/j.fochms.2024.100198] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Revised: 03/08/2024] [Accepted: 03/09/2024] [Indexed: 03/26/2024]
Abstract
Curcumin, a polyphenol natural product derived from turmeric, possesses diverse pharmacological effects due to its interactions with various cells and molecules. Recent studies have highlighted its immunomodulatory properties, including its impact on immune cells and mediators involved in immune responses. Th17 cells play a crucial role in promoting immune responses against extracellular pathogens by recruiting neutrophils and inducing inflammation. These cells produce inflammatory cytokines such as TNF-α, IL-21, IL-17A, IL-23, IL-17F, IL-22, and IL-26. Curcumin has been shown to significantly inhibit the proliferation of Th17 cells and reduce the production of inflammatory cytokines, including TNF-α, IL-22, and IL-17. This review aims to assess the effectiveness of curcumin and its underlying mechanisms in modulating Th17 cells.

Abstract
The interleukin (IL)-17 axis is involved in many inflammatory and autoimmune diseases. Secukinumab, an IL-17 inhibitor, has been approved for psoriasis treatment. There are accumulating cases of lupus erythematosus induced by IL-17 inhibition. Lupus nephritis after IL-17 inhibition has not been reported. We report the case of a 57-year-old man who developed membranous lupus nephritis after secukinumab treatment for psoriasis. Anti-SSA and PM-Scl antibodies were positive. dsDNA, anti-Smith, and anti-histone antibodies were negative, and serum complement was low. Secukinumab was discontinued, while tacrolimus was initiated, subsequently switched to cyclosporin, belimumab, glucocorticosteroid, and hydroxychloroquine with a good response. The relationship between lupus erythematosus and IL-17 inhibition requires further research.

Abstract
The current study aims to investigate the relationship betweSen serum IL-17 (IL-17) levels and systemic lupus erythematosus disease activity index (SLE-DAEI) in systemic lupus erythematosus (SLE) patients. In this case-control study, 36 patients with SLE and 40 healthy individuals matched for age and sex were included as the control group. The study measured serum IL-17 in both groups. The correlation between serum IL-17 with disease activity (as per SLE-DAI) and organ involvement in SLE patients. The case group in this study consisted of 4 males and 32 females with a mean age of 35 (17-54) years old, and the control group included six males and 34 females with a mean age of 37 (25-53) years old (p = .35). Serum IL-17 was higher in the cases than in the controls (536 pg/mL vs. 110 pg/mL; p < .001). There was a positive correlation between the serum levels of IL-17 and disease activity index (p < .001, rho = 0.93) among cases. Additionally, the serum levels of IL-17 were higher in patients with renal (p = .003) or central nervous system involvement (p < .001) than in patients without such involvement. Serum Il-17 is associated with SLE, and its serum levels correlate positively with the disease activity and renal and nervous system involvement.

Abstract
Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with a broad spectrum of clinical manifestations. The proposed pathophysiological hypotheses of SLE are numerous, involving both innate and adaptive abnormal immune responses. SLE is characterized by the overproduction of different autoantibodies that form immune complexes, which cause damage in different organs. Current therapeutic modalities are anti-inflammatory and immunosuppressive. In the last decade, we have witnessed the development of many biologicals targeting different cytokines and other molecules. One of them is interleukin-17 (IL-17), a central cytokine of a proinflammatory process that is mediated by a group of helper T cells called Th17. Direct inhibitors of IL-17 are used in psoriatic arthritis, spondyloarthritis, and other diseases. Evidence about the therapeutic potential of Th17-targeted therapies in SLE is scarce, and probably the most promising is related to lupus nephritis. As SLE is a complex heterogeneous disease with different cytokines involved in its pathogenesis, it is highly unlikely that inhibition of only one molecule, such as IL-17, will be effective in the treatment of all clinical manifestations. Future studies should identify SLE patients that are eligible for Th17-targeted therapy.

Abstract
INTRODUCTION The severity of lupus nephritis (LN) varies between different ethnicities. However, there are limited data regarding disease severity for LN in patients from the Arabian Gulf region; moreover, there are no treatment guidelines developed specifically for this population. The objective of this review was to characterise the incidence of LN, current treatment practices, the severity of LN, and the pathophysiology and biomarkers associated with LN in the Arabian Gulf region. METHODS A literature search using EMBASE was conducted in October, 2021 to identify publications reporting on the incidence, treatment practices, severity, pathophysiology or biomarkers associated with LN, from countries in the Arabian Gulf region (including Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates). Additional relevant publications were provided by collaborators. A manual review of the publications was conducted to determine their relevance and data on the outcomes of interest were extracted. RESULTS Of 3705 publications, 54 publications were identified as relevant. LN is one of the most commonly diagnosed renal diseases within the Arabian Gulf and approximately 10%-36% of all renal biopsies are for LN. Treatment patterns within the region appear to vary and generally follow treatment guidelines recommended by the Asia Pacific League of Associations for Rheumatology (APLAR), the European Alliance of Associations for Rheumatology (EULAR) and Kidney Disease Improving Global Outcomes (KDIGO). The majority of patients receive cyclophosphamide for induction therapy, whilst others receive mycophenolate mofetil. Most studies showed that the most frequently diagnosed class of LN within the Arabian Gulf region was Class IV (up to 63% of patients with LN). Sustained or increased levels of serum creatinine and proteinuria; and depressed levels of complement C3/C4 were commonly seen among patients with LN from the Arabian Gulf region. CONCLUSIONS This review identified that LN may manifest more severely among patients from the Arabian Gulf region than in other populations, such as Caucasian populations. A greater understanding of LN and the treatment practices within the region, as well as the development of more specific treatment guidelines for this population may help improve outcomes for patients with LN in the Arabian Gulf region.

Abstract
Objective To identify potential diagnostic markers of lupus nephritis (LN) based on bioinformatics and machine learning and to explore the significance of immune cell infiltration in this pathology. Methods Seven LN gene expression datasets were downloaded from the GEO database, and the larger sample size was used as the training group to obtain differential genes (DEGs) between LN and healthy controls, and to perform gene function, disease ontology (DO), and gene set enrichment analyses (GSEA). Two machine learning algorithms, least absolute shrinkage and selection operator (LASSO) and support vector machine-recursive feature elimination (SVM-RFE), were applied to identify candidate biomarkers. The diagnostic value of LN diagnostic gene biomarkers was further evaluated in the area under the ROC curve observed in the validation dataset. CIBERSORT was used to analyze 22 immune cell fractions from LN patients and to analyze their correlation with diagnostic markers. Results Thirty and twenty-one DEGs were screened in kidney tissue and peripheral blood, respectively. Both of which covered macrophages and interferons. The disease enrichment analysis of DEGs in kidney tissues showed that they were mainly involved in immune and renal diseases, and in peripheral blood it was mainly enriched in cardiovascular system, bone marrow, and oral cavity. The machine learning algorithm combined with external dataset validation revealed that C1QA(AUC = 0.741), C1QB(AUC = 0.758), MX1(AUC = 0.865), RORC(AUC = 0.911), CD177(AUC = 0.855), DEFA4(AUC= 0.843)and HERC5(AUC = 0.880) had high diagnostic value and could be used as diagnostic biomarkers of LN. Compared to controls, pathways such as cell adhesion molecule cam, and systemic lupus erythematosus were activated in kidney tissues; cell cycle, cytoplasmic DNA sensing pathways, NOD-like receptor signaling pathways, proteasome, and RIG-1-like receptors were activated in peripheral blood. Immune cell infiltration analysis showed that diagnostic markers in kidney tissue were associated with T cells CD8 and Dendritic cells resting, and in blood were associated with T cells CD4 memory resting, suggesting that CD4 T cells, CD8 T cells and dendritic cells are closely related to the development and progression of LN. Conclusion C1QA, C1QB, MX1, RORC, CD177, DEFA4 and HERC5 could be used as new candidate molecular markers for LN. It may provide new insights into the diagnosis and molecular treatment of LN in the future.

Abstract
Lupus nephritis (LN) is a severe manifestation of systemic lupus erythematosus (SLE), characterized by chronic and progressive inflammation of the kidneys. As with many other autoimmune diseases, LN is a multifactorial disease caused by genetic and environmental factors. Globally, LN can affect around 60% of SLE patients, and it was observed to be less frequent and severe in Caucasian patients compared to other ethnic groups, including Arabs. Data on LN in the United Arab Emirates (UAE) are scattered and scarce in literature. Nevertheless, LN is common, occurring in around 43%-55% of SLE patients in the UAE. Anecdotally, the demographics and clinical features of SLE in the UAE have been distinct. However, the paucity of supporting literature makes it difficult to draw meaningful conclusions. Over the past two decades, there have been improvements in understanding the pathogenesis of LN; however, many cellular and molecular mechanisms which are implicated in the disease development and progression remain ambiguous. Investigating the clinical, pathological, and genetic characteristics of LN in different cohorts of patients is of importance for a better understanding of its pathogenesis, and thus improving its outcome. As a result, we acknowledge the need for large-scale epidemiological, clinical, and genetic investigation of LN cohorts in the UAE and surrounding regions.

Abstract
Systemic lupus erythematosus (SLE) is a disease characterized by dysregulation and hyperreactivity of the immune response at various levels, including hyperactivation of effector cell subtypes, autoantibodies production, immune complex formation, and deposition in tissues. The consequences of hyperreactivity to the self are systemic and local inflammation and tissue damage in multiple organs. Lupus nephritis (LN) is one of the most worrying manifestations of SLE, and most patients have this involvement at some point in the course of the disease. Among the effector cells involved, the Th17, a subtype of T helper cells (CD4+), has shown significant hyperactivation and participates in kidney damage and many other organs. Th17 cells have IL-17A and IL-17F as main cytokines with receptors expressed in most renal cells, being involved in the activation of many proinflammatory and profibrotic pathways. The Th17/IL-17 axis promotes and maintains repetitive tissue damage and maladaptive repair; leading to fibrosis, loss of organ architecture and function. In the podocytes, the Th17/IL-17 axis effects include changes of the cytoskeleton with increased motility, decreased expression of health proteins, increased oxidative stress, and activation of the inflammasome and caspases resulting in podocytes apoptosis. In renal tubular epithelial cells, the Th17/IL-17 axis promotes the activation of profibrotic pathways such as increased TGF-β expression and epithelial-mesenchymal transition (EMT) with consequent increase of extracellular matrix proteins. In addition, the IL-17 promotes a proinflammatory environment by stimulating the synthesis of inflammatory cytokines by intrinsic renal cells and immune cells, and the synthesis of growth factors and chemokines, which together result in granulopoiesis/myelopoiesis, and further recruitment of immune cells to the kidney. The purpose of this work is to present the prognostic and immunopathologic role of the Th17/IL-17 axis in Kidney diseases, with a special focus on LN, including its exploration as a potential immunotherapeutic target in this complication.

Abstract
The CC chemokine receptor 6 (CCR6) and its sole chemokine ligand, CCL20, are an intriguing pair that have been implicated in a growing number of inflammatory, autoimmune and malignant disease processes. Recent observations have also highlighted this chemokine axis in the regulation of humoral immune responses. Through this review article, we explore the emerging links of CCR6-CCL20 with an archetypal autoimmune disease of humoral dysregulation: systemic lupus erythematosus (SLE). CCR6 is expressed prominently on several immune cells involved in the pathogenesis of SLE, such as dendritic cells and T-helper 17 cells. CCR6's expression is correlated with disease activity and serological markers of disease severity, suggesting a possible role in disease pathogenesis. However, there are numerous holes in our understanding of the functions of CCR6 and CCL20, and future studies are required to determine if there are any diagnostic, prognostic or monitoring roles for these important molecules.

Abstract
Interleukin-17 (IL-17), a pleiotropic proinflammatory cytokine, is reported to be significantly generated by a distinct subset of CD4+ T-cells, upgrading cancer-elicited inflammation and preventing cancer cells from immune surveillance. T-helper (Th)17 cells produced from naive CD4+ T cells have recently been renowned and generally accepted, gaining eminence in cancer studies and playing the effective role in context of cancer. Th17 cells are the main source of IL-17-secreting cells, It was found that other cell types produced this cytokine as well, including Group 3 innate lymphoid cells (ILC3), δγT cells, invariant natural killer T (iNKT) cells, lymphoid-tissue inducer (LTi)-like cells and Natural killer (NK) cells. Th17-associated cytokines give impetus to tumor progression, or inducing angiogenesis and metastasis. This review demonstrates an understanding on how the pro- or antitumor function of Th17 cells and IL-17 may change cancer progression, leading to the appearance of complex and pivotal biologic activities in tumor.

Abstract
Aim: The objective of this study was to identify the association between genotypes of miR-146a rs2910164 and expression of TRAF6 as well as the risk of lupus nephritis (LN). Results: A total of 567 systemic lupus erythematosus patients both with and without LN were included in the study. The luciferase activity of cells that carried miR-146a mimics was much lower than control and the miR-146a mRNA expression with the GG SNP was significantly overexpressed compared with that in GC and CC groups. Expressions of TRAF6 mRNA and protein with GG were markedly lower than those in GC and CC groups. Mesangial cells treated with miR-146a inhibitors displayed higher expression of TRAF6 mRNA and protein compared with scramble control, miR-146a mimics and TRAF6 siRNA groups. Conclusion: Rs2910164 is associated with the risk of LN and could function as a therapeutic target of the disease.

Abstract
The presence of Th17 cells and IL-27 is observed in a variety of inflammatory associated cancers. However, there are some data on the role of Th17 cells and IL-27 in the regulation of immune reactions in non-small-cell lung cancer (NSCLC). The aim of this study is to assess the variation of Th17 cells and IL-27 in the peripheral blood (PB) of patients with NSCLC. The proportion of Th17 cells in peripheral blood mononuclear cells (PBMCs) was evaluated by flow cytometry. The serum concentrations of IL-27 and IL-17 were measured by enzyme-linked immunosorbent assay (ELISA). The mRNA expression of RORγt and IL-27 in the peripheral blood was examined by real-time quantitative polymerase chain reaction (QPCR). Expression of IL-27 was lower in NSCLC patients compared with normal controls. The frequency of Th17 cells was increased in NSCLC patients, accompanied by the upregulation of IL-17 and RORγt. IL-27 negatively correlated with the number of Th17 cells and the RORγt mRNA. Our results indicate that IL-27 might inhibit Th17 differentiation in NSCLC patients and better understanding of the regulatory effects of IL-27 on Th17 cells may shed light on potential new targets in cancer prevention and therapy.
