Abstract
T‑cell/transmembrane immunoglobulin and mucin domain containing 4 (TIM‑4) is a phosphatidylserine receptor that is mainly expressed on antigen‑presenting cells and is involved in the recognition and efferocytosis of apoptotic cells. TIM‑4 has been found to be expressed in immune cells such as natural killer T, B and mast cells and to participate in multiple aspects of immune regulation, suggesting that TIM‑4 may be involved in a variety of immune‑related diseases. Recent studies have confirmed that TIM‑4 is also abnormally expressed in a variety of malignant tumor cells and is closely associated with the occurrence and development of tumors and the tumor immune microenvironment. The present study aimed to describe the expression and functional characteristics of TIM‑4 in detail and to comprehensively discuss its role in pathophysiological processes such as infection, allergy, metabolism, autoimmunity and tumor immunity. The current review provided a comprehensive understanding of the functions and characteristics of TIM‑4, as well as novel ideas for the diagnosis and treatment of diseases.

T-Cell Immunoglobulin and Mucin Domain-Containing Protein-4 Is Critical for Kupffer Cell Homeostatic Function in the Activation and Resolution of Liver Ischemia Reperfusion Injury. Hepatology 2021; 74:2118-2132. [PMID: 33999437 PMCID: PMC9060306 DOI: 10.1002/hep.31906] [Citation(s) in RCA: 38] [Impact Index Per Article: 12.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2021] [Revised: 03/26/2021] [Accepted: 04/29/2021] [Indexed: 12/13/2022]
Abstract
BACKGROUND AND AIMS Liver ischemia reperfusion injury (IRI) remains an unresolved clinical problem. This study dissected roles of liver-resident macrophage Kupffer cells (KCs), with a functional focus on efferocytosis receptor T-cell immunoglobulin and mucin domain-containing protein-4 (TIM-4), in both the activation and resolution of IRI in a murine liver partial warm ischemia model. APPROACH AND RESULTS Fluorescence-activated cell sorting results showed that TIM-4 was expressed exclusively by KCs, but not infiltrating macrophages (iMФs), in IR livers. Anti-TIM-4 antibody depleted TIM-4+ macrophages in vivo, resulting in either alleviation or deterioration of liver IRI, which was determined by the repopulation kinetics of the KC niche with CD11b+ macrophages. To determine the KC-specific function of TIM-4, we reconstituted clodronate-liposome-treated mice with exogenous wild-type or TIM-4-deficient KCs at either 0 hour or 24 hours postreperfusion. TIM-4 deficiency in KCs resulted in not only increases in the severity of liver IRI (at 6 hours postreperfusion), but also impairment of the inflammation resolution (at 7 days postreperfusion). In vitro analysis revealed that TIM-4 promoted KC efferocytosis to regulate their Toll-like receptor response by up-regulating IL-10 and down-regulating TNF-α productions. CONCLUSIONS TIM-4 is critical for KC homeostatic function in both the activation and resolution of liver IRI by efferocytosis.

Abstract
T-cell immunoglobulin and mucin domain containing 4 (Tim-4) is a phosphatidylserine receptor and is selectively expressed on antigen presenting cells. Recently, Tim-4 was reported to be expressed on iNKT cells, B1 cells, and tumor cells, suggesting it has multiple biological functions. In this review, we mainly summarize the expression and regulation of Tim-4 in immune cells including T cells, macrophages, dendritic cells, NKT cells, B cells, and mast cells. The expression of Tim-4 in these cells implies that Tim-4 might participate in immune related diseases. Emerging evidence emphasizes a substantial role for Tim-4 in maintaining homeostasis by regulating various immune responses, including viral infection, allergy, autoimmunity, and tumor immunity. Here, we collectively evaluated the role of Tim-4 in health and diseases. This summary will be extremely useful to fully understand the function of Tim-4 in the pathogenesis of immune related diseases, which would provide novel clues for the diagnosis and treatment of diseases.

Abstract
The incidence of gastric cancer is high, especially in China. The present study aims to provide a novel therapeutic target for gastric cancer. Peripheral blood, cancerous and paracancerous tissues were collected from patients with gastric cancer. T-cell immunoglobulin mucin domain-3 (Tim-3) expression in T-cells was measured and the correlation between Tim-3 expression and the T staging of gastric cancer was analyzed. The levels of T-cell secreted interferon (IFN)-γ and tumor necrosis factor (TNF)-α were assessed following Tim-3 signaling pathway activation. A nude mouse model of gastric cancer was established and Tim-3-stimulated T-cells were injected into the mice to evaluate tumor growth. The results of the present study demonstrated that Tim-3 expression levels from the paracancerous and cancerous gastric tissues were significantly increased compared with the peripheral blood, while its expression was significantly increased in cancerous compared with paracancerous gastric tissues. With the T staging of gastric cancer increasing, the expression of Tim-3 gradually increased. The activation of the Tim-3 signaling pathway in T-cells may inhibit IFN-γ and TNF-α secretion, and the results from the nude mice tumor model demonstrated that the inhibitory effect on tumor growth by T-cells was reduced by Tim-3 signaling pathway activation. The expression level of Tim-3 on the surface of tumor infiltrating T-cells in gastric cancer tissue increases significantly and the increased Tim-3 signaling may inhibit the function of T-cells. The results suggest that the increased expression of Tim-3 on T-cells may be involved the development of gastric cancer.

Abstract
BACKGROUND A characteristic pathology of early onset myasthenia gravis is thymic hyperplasia with ectopic germinal centers (GC). However, the mechanisms that trigger and maintain thymic hyperplasia are poorly characterized. Dysregulation of small, non-coding microRNAs (miRNAs) and their target genes has been identified in the pathology of several autoimmune diseases. We assessed the miRNA and mRNA profiles of the MG thymus and have investigated their role in GC formation and maintenance. METHODS MG thymus samples were assessed by histology and grouped based upon the appearance of GC; GC positive and GC negative. A systems biology approach was used to study the differences between the groups. Our study included miRNA and mRNA profiling, quantitative real-time PCR validation, miRNA target identification, pathway analysis, miRNA-mRNA reciprocal expression pairing and interaction. RESULTS Thirty-eight mature miRNAs and forty-six annotated mRNA transcripts were differentially expressed between the two groups (>1.5 fold change, ANOVA p<0.05). The miRNAs were found to be involved in immune response pathways and identified in other autoimmune diseases. The cellular and molecular functions of the mRNAs showed involvement in cell death and cell survival, cellular proliferation, cytokine signaling and extra-cellular matrix reorganization. Eleven miRNA and mRNA pairs were reciprocally regulated. The Regulator of G protein Signalling 13 (RGS13), known to be involved in GC regulation, was identified in specimens with GC and was paired with downregulation of miR-452-5p and miR-139-5p. MiRNA target sites were validated by dual luciferase assay. Transfection of miRNA mimics led to down regulation of RGS13 expression in Raji cells. CONCLUSION Our study indicates a distinct miRNA and mRNA expression pattern in ectopic GC in MG thymus. These miRNAs and mRNAs are involved in regulatory pathways common to inflammation and immune response, cell cycle regulation and anti-apoptotic pathways suggesting their involvement in support of GC formation in the thymus. We demonstrate for the first time that miR-139-5p and miR-452-5p negatively regulate RGS13 expression.

Abstract
Ischemia-reperfusion injury (IRI) of the liver is a primary cause of post-liver-surgery complications and ischemic preconditioning (IPC) has been verified to protect against ischemia-reperfusion injury. TIM-4 activation plays an important role in macrophage mediated hepatic IRI. This study aimed to determine whether IPC protects against hepatic IRI through inhibiting TIM-4 activation. In this study, a model of warm liver ischemia (90 min) and reperfusion for 6 h was used. Mice were subjected to ischemia-reperfusion injury with or without ischemic preconditioning and TIM4 blocking antibody. Western blot was determined to detect the expression of TIM4 protein and mitochondrial apoptosis-related protein expression. Liver function was evaluated using the level of alanine transaminase (ALT) and aspartate transaminase (AST), cell apoptosis and pathological examination. We found that compared with the control group, ischemic preconditioning reduced IRI by decreasing hepatocyte apoptosis, ALT, AST, CD68 and CD3 positive cells, tissue myeloperoxidase activity(MPO), and downregulating TIM-4 expression. TIM4 blocking could reduce CD68 and CD3 positive cells in liver. Furthermore, activated monocytes transfusion significantly abolished the protect effect of IPC with increased hepatocyte apoptosis, ALT, AST, CD68 and CD3 positive cells while TIM-4 knockdown monocytes lost this effect. These results suggested that IPC protects against hepatic IRI by downregulating TIM-4 and indicated TIM-4 would be a novel therapeutic target to minimize IRI.

NF-κB p50 activation associated with immune dysregulation confers poorer survival for diffuse large B-cell lymphoma patients with wild-type p53. Mod Pathol 2017; 30:854-876. [PMID: 28281555 DOI: 10.1038/modpathol.2017.5] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2016] [Revised: 12/29/2016] [Accepted: 12/29/2016] [Indexed: 12/12/2022]
Abstract
Dysregulated NF-κB signaling is critical for lymphomagenesis, however, the expression and clinical relevance of NF-κB subunit p50 in diffuse large B-cell lymphoma have not been evaluated. In this study, we analyzed the prognostic significance and gene expression signatures of p50 nuclear expression as a surrogate for p50 activation in 465 patients with de novo diffuse large B-cell lymphoma. We found that p50+ nuclear expression, observed in 34.6% of diffuse large B-cell lymphoma, predominantly composed of activated B-cell-like subtype, was an independent adverse prognostic factor in patients with activated B-cell-like diffuse large B-cell lymphoma. It was also an adverse prognostic factor in patients with wild-type TP53 independent of the activated B-cell-like and germinal center B-cell-like subtypes, even though p50 activation correlated with significantly lower levels of Myc, PI3K, phospho-AKT, and CXCR4 expression and less frequent BCL2 translocations. In contrast, in germinal center B-cell-like diffuse large B-cell lymphoma patients with TP53 mutations, p50+ nuclear expression correlated with significantly better clinical outcomes, and decreased p53, Bcl-2, and Myc expression. Gene expression profiling revealed multiple signaling pathways potentially upstream the p50 activation through either canonical or noncanonical NF-κB pathways, and suggested that immune suppression, including that by the immune checkpoint TIM-3 and that through leukocyte immunoglobulin-like receptors, but not antiapoptosis and proliferation, may underlie the observed poorer survival rates associated with p50+ nuclear expression in diffuse large B-cell lymphoma. In conclusion, these data show that p50 is important as a unique mechanism of R-CHOP-resistance in activated B-cell-like diffuse large B-cell lymphoma and in patients without TP53 mutations. The results also provide insights into the regulation and function of p50 in diffuse large B-cell lymphoma and its cross talk with the p53 pathway with important therapeutic implications.
