TIM-3 rs1036199 polymorphism increases susceptibility to autoimmune diseases: evidence based on 4200 subjects. Biosci Rep 2018; 38:BSR20181235. [PMID: 30377229 PMCID: PMC6250810 DOI: 10.1042/bsr20181235] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2018] [Revised: 10/23/2018] [Accepted: 10/29/2018] [Indexed: 01/10/2023] Open
Abstract
Conflicting results have been reported regarding differing studies on the association between T-cell immunoglobulin and mucin domain 3 polymorphisms and autoimmune disease. The purpose of the present study was to evaluate the association of TIM-3 rs1036199 (4259 G/T) polymorphism with autoimmune disease susceptibility. A meta-analysis was performed to obtain a more precise evaluation of the association. Ten eligible studies were retrieved by searching PubMed, Embase and Web of Science databases, and statistical analyses were performed using STATA software. The pooled results indicated that TIM-3 rs1036199 polymorphism was significantly associated with an increased risk of overall autoimmune disease in allele comparison (G versus T: OR = 1.59, 95%CI: 1.17-2.17) and heterozygous comparison (GT versus TT: OR = 1.68, 95%CI: 1.37-2.06). Subgroup analyses based on disease type demonstrated that TIM-3 rs1036199 polymorphism was associated with an increased risk of rheumatic arthritis (G versus T: OR = 1.88, 95%CI: 1.45-2.44; GT versus TT: OR = 2.02, 95%CI: 1.53-2.65), especially in Asian populations.

Abstract
The aim of this study was to evaluate the expression of human T cell immunoglobulin domain and mucin-3 (Tim-3) in renal tissue from patients with immunoglobulin A nephropathy (IgAN) and without IgAN and to evaluate the difference in Tim-3 expression between them. A total of 71 patients with IgAN as IgA group and 13 patients without IgAN as control group were enrolled in the present study. Patients in IgAN accepted percutaneous renal biopsy. We examined the expression of Tim-3 in renal tissue and the serological parameters in serum from all enrolled cases. The expression of Tim-3 and serological parameters were compared between the different groups. Positive staining of Tim-3 protein was seen in 94.3 % patients with IgAN (67 out of 71), but only 15.4 % (2 out of 13) in the cases without IgAN were positive staining of Tim-3. There were significant differences between two groups in almost all serological markers, which reflect IgAN activity. There was a nearly positive correlation between pathological manifestations and expression degree of Tim-3. High immuno-reactivity of Tim-3 was found to be significantly correlated with serological grade (p < 0.001) in IgA group, but there was no such phenomenon in control group. The results showed that there was the expression of Tim-3 in renal tissue from the patients with IgAN, but rarely expression in cases without IgAN. Expression of Tim-3 was associated with the diseases' activity.

Abstract
Efficient removal of apoptotic polymorphonuclear leukocytes (PMNs) is an important step in the resolution of inflammation, which protects tissues from the noxious contents of dying cells. While the impairment of apoptotic PMNs removal has been demonstrated for macrophages in systemic lupus erythematosus (SLE), recent studies show that monocytes are also capable of such phagocytosis, although their involvement in SLE is not clear. Therefore, we characterized phagocytosis of apoptotic PMNs by monocytes in 22 patients with SLE and 22 healthy controls. Using flow cytometry we demonstrate that in SLE peripheral blood monocytes show impaired phagocytosis of autologous apoptotic PMNs, while they efficiently engulf apoptotic PMNs isolated from healthy subjects. Monocytes CD14highCD16+ and CD14dimCD16+ more efficiently interacted with apoptotic neutrophils than CD16– cells both in SLE and healthy subjects. Monocytes in SLE showed modestly decreased expression of CD35 and CD91 and increased expression of T Cell Ig- and mucin-domain-containing molecule-3 (TIM-3); however, these differences were evident mainly in selected subsets of monocytes (CD16+) while defects in phagocytosis were observed in all monocyte subsets. Apoptotic cell-dependent induction of lipopolysaccharide (LPS) stimulated production of anti-inflammatory cytokine IL-10 by peripheral blood mononuclear cells (PBMC) was blunted in SLE while the production of pro-inflammatory cytokine TNF-α was unchanged.

Abstract
T cell immunoglobulin and mucin domain-3 (TIM-3), originally identified as a T helper (Th) 1-specific type I membrane protein, plays a vital role in Th1 immunity and tolerance induction through interaction with its ligand, galectin-9. The binding of TIM-3 by galectin-9 serves to downregulate Th1 responses. Moreover, the regulatory function of TIM-3 has been extended to other cells, such as Th17 cells, CD4(+) CD25(+) regulatory T cells (Tregs), CD8(+) T cells and certain innate immune cells. Previous studies have acknowledged that the TIM-3 pathway is involved in the pathogenesis of several human autoimmune diseases, such as systemic lupus erythematous, rheumatoid arthritis and aplastic anaemia. Moreover, genetic data suggest a role for TIM-3 in human autoimmune diseases. However, in immune thrombocytopenia (ITP), a common Th1- and possibly Th17-biased autoimmune disorder, the role of TIM-3 has not been explored. Recently, our data have demonstrated that TIM-3 expression is reduced in ITP patients, and we have found a potential link between ITP and the TIM-3 pathway. In this article, we discuss and speculate on the role of the TIM-3 pathway in ITP.

Abstract
BACKGROUND Activated T helper (Th)-1 CD4+ cells and their mediators are essential for pathogenesis processes in aplastic anaemia (AA). Recently, T-cell immunoglobulin and mucin domain 3 (Tim-3) molecules, a Th1-specific type 1 membrane protein, have been suggested to be important regulators of both Th1 proliferation and the development of tolerance. Moreover, T-box expressed in T cells (T-bet) is a major T cell transcription factor that regulates the expression of Th1 cytokine genes and plays a crucial role in T cell differentiation. The function of Tim-3 and its association with T-bet in the pathophysiology of AA remain unclear. DESIGN AND METHODS Plasma IL-18, IFN-γ and IL-4 levels were measured in patients with newly diagnosed AA (n = 29), AA in remission (n = 22) and healthy subjects (n = 30) via enzyme-linked immunosorbent assay (ELISA). CD4+ Tim-3+ cells were evaluated via flow cytometry and expressed as a percentage of the total number of CD4+ cells. Using real-time quantitative polymerase chain reaction (RT-PCR) and mRNA expression analysis the expression levels of Tim-3, IL-18, IFN-γ and T-box (T-bet) were examined in all subjects. RESULTS Tim-3 was expressed on CD4+T cells. The percentages of Tim-3 cells identified in newly diagnosed patients were significantly deceased compared with the controls. Meanwhile T-bet, IL-18 and IFN-γ levels were significantly elevated in patients, which resulted in an increased ratio of T-bet/Tim-3 expression levels in patients with active disease. During the remission stages, the levels of these cytokines were comparable with those observed in the healthy controls. CONCLUSIONS These results suggest that the imbalanced expression of Tim-3 and T-bet may play a role in the pathogenesis and course of AA, and the downregulation of T-bet/Tim-3 may represent a reasonable therapeutic strategy for AA treatment.

Abstract
OBJECTIVE T-cell immunoglobulin and mucin domain-3 (TIM-3) is a unique cell surface molecule expressed on T helper 1 (Th1) cells. Engagement of TIM-3 by ligand galectin-9 leads to dampened Th1 immunity. We investigated TIM-3 and galectin-9 expression in inflammatory bowel disease (IBD) patients and in healthy controls, and evaluated the immune role of the TIM-3 pathway in Crohn's disease (CD) pathogenesis. MATERIAL AND METHODS We used flow cytometry to investigate TIM-3 expression on mononuclear cells isolated from the intestinal mucosa and peripheral blood cells of patients with IBD and healthy controls. We also evaluated galectin-9 mRNA expression on endoscopically obtained intestinal mucosal cells. RESULTS TIM-3 was constitutively expressed on Th cells isolated from the intestinal mucosa of IBD patients and healthy controls. While we observed low TIM-3 expression on Th cells isolated from peripheral blood mononuclear cells (PBMCs), high TIM-3 expression was induced by Th1 stimulation. The level of TIM-3 expression on Th cells isolated from intestinal mucosa and stimulated PBMCs was significantly lower in CD patients than in healthy controls. CONCLUSIONS Our data show that TIM-3 upregulation on Th1 cells is dysregulated in patients with CD. Low TIM-3 expression on Th1 cells may provide a clue toward resolution of the inflammation associated with chronic inflammatory disease. These findings should contribute to develop understanding of CD pathogenesis.

Abstract
The aim of this study was to investigate T-cell immunoglobulin and mucin domain 3 (TIM3) genetic polymorphisms and rheumatoid arthritis (RA) according to the shared epitope (SE) status. Six single nucleotide polymorphisms (SNPs: rs11742259 [C/T], rs10515746 [C/A], rs35960726 [A/G], rs1036199 [A/C], rs4704846 [A/G], and rs11134551 [A/G]) in the TIM3 gene from 366 RA patients and 389 healthy controls were investigated using the real-time polymerase chain reaction method. Associations between these SNPs and clinical manifestations (including SE status) were investigated using the SPSS program and Haploview. Polymorphisms of rs35690726 (AG+ GG vs AA: 8.2% vs 1.8%, p(c) < 0.001) were significantly associated with RA with or without SE (p(c) < 0.001 or p(c) = 0.009, respectively). Polymorphisms of rs11742259 (p(c) = 0.003) and rs1036199 (p(c) = 0.012) were significantly different in RA patients with SE, but not in those without SE. In haplotype analysis with a permutation test for the first 4 SNPs (rs11742259, rs10515746, rs35690726, and, rs1036199), CCAA, CCGA, CCGC, and CAAA haplotypes were significantly associated with RA. The clinical characteristics of RA patients were not significantly associated with any TIM3 polymorphism. TIM3 genetic polymorphisms may have a role in the development of RA regardless of a shared epitope status.

Abstract
Systemic lupus erythematosus (SLE) is a prototypic systemic autoimmune diseases, which affects multiple organ systems such as kidney. The imbalance of T-helper 1 (Th1)/Th2 cells is critical in the pathogenesis of SLE. The T-cell immunoglobulin mucin (TIM) proteins comprise a family of cell surface molecules expressed on T cells that regulate Th1- and Th2-cell-mediated immunity. Recent work has found increased expression of TIM-1 and TIM-3 ligand (galactin-9) mRNA in SLE patients and implied that TIM proteins might be involved in the pathogenesis of SLE. In this study, genotyping of single-nucleotide polymorphisms (SNPs) was performed for TIM-1 (rs1501909 and rs12522248) and TIM-3 (rs9313439 and rs10515746) in 202 SLE patients and 217 healthy individuals in a Chinese population. Results showed no significant differences existed between the patients with SLE and the controls as well as SLE patients with nephritis and those without nephritis, in all four SNPs. The findings suggest that the polymorphisms of TIM gene family might not contribute to SLE susceptibility in the Chinese population. However, it should be noted that the statistical power of our study is relatively low, which likely did not have adequate power to detect the actual correlation between the selected SNPs and SLE susceptibility; moreover, we cannot discard a possible association of other variants within the region covering TIM with SLE as a genetic risk factor, with larger samples in different populations.

Abstract
PURPOSE OF REVIEW Immune thrombocytopenia (ITP) is a bleeding disorder in which both antibody and cell-mediated autoimmune responses are directed against an individual's own platelets and/or megakaryocytes, leading to either enhanced platelet destruction and/or reduced platelet production, respectively. The cause of this platelet-specific autoimmunity remains unknown, but there has been a constant stream of recent publications that suggest ITP is the result of T-cell dysregulation. RECENT FINDINGS In the last 18 months, a rich tapestry of studies has emerged that seems to clarify some immunopathologic issues in ITP while raising new questions related to ITP pathogenesis. The current view on the immunopathogenic mechanisms associated with ITP appears to particularly concentrate on how incompetent CD4+ T-regulatory cells (Tregs) allow autoimmune effector mechanisms to proceed and cause thrombocytopenia. There is a parallel body of recent literature focusing on molecular mimicry mechanisms, B-cell abnormalities, abnormal cytokine patterns and genetic studies in ITP. Of interest, one can recognize inter-relationships between these immune dysregulations. SUMMARY This article will discuss the literature from the past 18 months pertaining to these observations and will show that whereas many of the T-cell defects have been clarified, new questions have also come to light and more immunopathological research is warranted.

Abstract
PURPOSE T cell immunoglobulin and mucin domain-containing molecule 3 (TIM-3) could weaken the Th1-mediated anti-tumor responses and accelerate the tumor cell proliferation by inhabiting the production of IL-2 or IFN-γ. This study was to assess the association between TIM-3 genetic variations and the development of gastric cancer. PATIENTS AND METHODS Five polymorphisms located in the promoter or encoding region of TIM-3 gene were genotyped in 212 gastric cancer patients and 252 controls who matched with the patients on the frequency of age, gender, smoking, and drinking. Logistic regression was used to determine whether the inherited variations within TIM-3 gene were associated with gastric cancer risk. Linkage disequilibrium and Haplotype analyses were performed by using SHEsis program. RESULTS By the individual genotype analysis, three polymorphisms (-574G/T, -882C/T, and -1516G/T) within TIM-3 gene were significantly associated with gastric cancer in the study population [ORs (95% CIs): 2.74 (1.21-6.20), 3.19 (1.29-7.91), and 2.03 (1.15-3.59); respectively]. Among the gastric cancer patients, the relationship between the -1516 polymorphic genotype and the distant metastasis of tumor was found (OR = 2.21, 95% CI = 1.05-4.63). Under the analysis of haplotypes, an even stronger association with haplotype TTGCT was observed in gastric cancer risk (OR = 5.57, 95% CI: 1.04-29.80, P = 0.024). CONCLUSION These results indicated that the three genetic variations within the TIM-3 gene promoter may be associated with the increased susceptibility to gastric cancer, especially among the haplotypes with the risk.

Abstract
The genomic revolution in medicine has not escaped attention of clinicians and scientists involved in medical management and research studies of immune thrombocytopenic purpura (ITP). In principle, ITP biology and care will benefit greatly from modern methods to understand the patterns of gene expression and genetic markers associated with fundamental parameters of the disease including predictors of remission, risk factors for severity, determinants of response to various therapies, and possibly biological sub-types. However, applying modern genetics to ITP carries severe challenges: (a) Achieving adequate sample sizes is a fundamental problem because ITP is rare (and in pediatric ITP, chronic cases constitute only about one fourth of the total); (b) familial transmission of childhood ITP is so rare that a convincing pedigree requires consideration of other immunologic or hematologic disorders; (iii) ITP is probably biologically heterogeneous, based on clinical observations, immunological studies, and animal models. Here we review the advantages and disadvantages of potential genetic approaches. Sufficient information is available to set reasonable bounds on which genetic analyses of ITP are feasible and how they are most likely to be accomplished.
