Abstract
OBJECTIVE Autoimmune diseases (AD) account for a high percentage of the population. One of the most prevalent is autoimmune thyroiditis (AIT). However, the therapeutic effects of Buzhong Yiqi (BZYQ) decoction on AIT have not been studied yet. The majority of the present study was conducted on NOD.H-2h4 mice in an attempt to ascertain the therapeutic effects of BZYQ decoction on AIT. METHODS The 0.05% sodium iodide water (NaI)-induced AIT mice model was established. A total of nine NOD.H-2h4 mice were randomly divided into three groups: the normal group provided with regular water, the model group drinking freely 0.05% NaI, and the treatment group treated with BZYQ decoction (9.56 g/kg) after NaI supplementation (NaI + BZYQ). BZYQ decoction was administered orally once daily for eight weeks. The thyroid histopathology test was used to measure the severity of lymphocytic infiltration. An enzyme-linked immunosorbent assay (ELISA) was used to determine the levels of anti-thyroglobulin antibody (TgAb), interleukin (IL)-1β, IL-6, and IL-17. The Illumina HiSeq X sequencing platform was utilized to analyze the thyroid tissue by mRNA expression profiles. Bioinformatics analysis was used to investigate the biological function of the differentially expressed mRNAs. In addition, the expression of Carbonyl Reductase 1 (CBR1), 6-Pyruvoyltetrahydropterin Synthase (PTS), Major Histocompatibility Complex, Class II (H2-EB1), Interleukin 23 Subunit Alpha (IL-23A), Interleukin 6 Receptor (IL-6RA), and Janus Kinase 1 (JAK1) was measured by quantitative real-time PCR (qRT-PCR). RESULTS The treatment group exhibited significantly lower rates of thyroiditis and lymphocyte infiltration compared to the model group. Serum levels of TgAb, IL-1β, IL-6, and IL-17 were significantly higher in the model group, but they fell dramatically after BZYQ decoction administration. According to our results, 495 genes showed differential expression in the model group compared to the control group. Six hundred twenty-five genes were significantly deregulated in the treatment group compared to the model group. Bioinformatic analysis showed that most mRNAs were associated with immune-inflammatory responses and were involved in multiple signaling pathways, including folate biosynthesis and the Th17 cell differentiation pathway. CBR1, PTS, H2-EB1, IL- 23A, IL-6RA and JAK1 mRNA participated in folate biosynthesis and the Th17 cell differentiation pathway. The qRT-PCR analysis confirmed that the above mRNAs were regulated in the model group compared to the treatment group Conclusion: The results of this investigation have revealed novel insights into the molecular mechanism of action of BZYQ decoction against AIT. The mechanism may be partially attributed to the regulation of mRNA expression and pathways.

ENVIRONMENTAL TOXICOLOGY 2023; 38:2574-2584. [PMID: 37598415 DOI: 10.1002/tox.23893] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Revised: 06/14/2023] [Accepted: 07/01/2023] [Indexed: 08/22/2023]
Abstract
Excess iodine will trigger the occurrence of autoimmune thyroiditis (AIT), and programmed death-1 (PD-1)/programmed death ligand (PD-L) will also contribute to the development of AIT. The purpose of this study was to explore the role that negative regulatory signals mediated by PD-1/PD-L play in the development of spontaneous autoimmune thyroiditis (SAT) in NOD.H-2h4 mice when they are exposed to iodine. Programmed death ligand 1 (PD-L1) antibody was administered intraperitoneally to NOD.H-2h4 mice. The relevant indicators were determined by flow cytometry, real-time quantitative polymerase chain reaction, enzyme-linked immunosorbent assay, immunohistochemistry, pathological hematoxylin and eosin staining, and arsenic-cerium catalytic spectrophotometry. Results showed that the level of urinary iodine, the level of thyroid lymphocyte infiltration, the level of thyroglobulin antibodies (TgAb) and interferon (IFN-γ)/tumor necrosis factor (TNF-α)/interleukin (IL-2)/IL-17, and the relative expression of PD-1/PD-L1/programmed death-2 (PD-L2) increased with the intervention of excess iodine. After the intervention of the PD-L1 antibody, the expression of PD-1/PD-L1/PD-L2 in different degrees was inhibited, but the level of thyroid lymphocyte infiltration and serum TgAb/IFN-γ/TNF-α/ IL-2/IL-17 did not decrease. Collectively, although PD-1/PD-L participates in the occurrence of SAT and induces inflammation, administration of the PD-L1 antibody does not effectively improve the pathological process of SAT. More research is needed to determine whether PD-1/PD-L intervention can treat autoimmune thyroid disease.

Abstract
Microglia-mediated neuroinflammation plays an important role in multiple sclerosis (MS). This study explored whether curcumin has a protective effect on experimental autoimmune encephalomyelitis (EAE), and the specific mechanism was investigated. We found that curcumin attenuates the severity of EAE mice. It inhibits the activation of microglia in the spinal cord of EAE mice and LPS-stimulated BV-2 cells. The findings clarify that curcumin may inhibit the inflammatory response mediated by microglia by inactivating the AXL/JAK2/STAT3 signaling pathway, which laid a theoretical foundation for the clinical management of MS.

Abstract
CONTEXT Ginsenoside Rb1 (Rb1) exerts many beneficial effects and protects against cardiovascular disease. OBJECTIVE To investigate whether Rb1 could attenuate age-related vascular impairment and identify the mechanism. MATERIALS AND METHODS Female C57BL/6J mice aged 2 and 18 months, randomly assigned to Young, Young + 20 mg/kg Rb1, Old + vehicle, Old + 10 mg/kg Rb1 and Old + 20 mg/kg Rb1 groups, were daily intraperitoneal injected with vehicle or Rb1 for 3 months. The thoracic aorta segments were used to inspect the endothelium-dependent vasorelaxation. Left thoracic aorta tissues were collected for histological or molecular expression analyses, including ageing-related proteins, markers relevant to calcification and fibrosis, and expression of Gas6/Axl. RESULTS We found that in Old + vehicle group, the expression of senescence proteins and cellular adhesion molecules were significantly increased, with worse endothelium-dependent thoracic aorta relaxation (58.35% ± 2.50%) than in Young group (88.84% ± 1.20%). However, Rb1 treatment significantly decreased the expression levels of these proteins and preserved endothelium-dependent relaxation in aged mice. Moreover, Rb1 treatment also reduced calcium deposition, collagen deposition, and the protein expression levels of collagen I and collagen III in aged mice. Furthermore, we found that the downregulation of Gas6 protein expression by 41.72% and mRNA expression by 52.73% in aged mice compared with young mice was abrogated by Rb1 treatment. But there was no significant difference on Axl expression among the groups. CONCLUSIONS Our study confirms that Rb1 could ameliorate vascular injury, suggesting that Rb1 might be a potential anti-ageing related vascular impairment agent.

Abstract
Background Prunella vulgaris L. (PV) has been used to treat autoimmune thyroiditis (AIT), but the underlying mechanism remains unknown. The present study was designed to evaluate the effect of PV on AIT and explore the role of high-mobility group box-1 (HMGB1) signaling in PV-mediated effects in vivo and in vitro. Methods In the present study, bioactive components of PV were identified using UPLC-ESI-MS. The protective effects and potential mechanisms critical for the anti-inflammatory and immunomodulatory effects of PV in AIT were investigated in a rat model of thyroglobulin-induced experimental autoimmune thyroiditis (EAT) and in lipopolysaccharide (LPS)-induced thyroid follicular cells (TFCs). Results The main bioactive compound identified in PV was rosmarinic acid. The thyroid volume, thyroiditis inflammation score and serum thyroglobulin antibody levels of EAT rats were attenuated by PV treatment (P<0.01). In addition, PV significantly reduced the elevated levels of the proinflammatory cytokines TNF-α, IL-6, IL-1β and monocyte chemoattractant protein-1 (MCP-1) both in vivo (P<0.01) and in vitro (P<0.05). PV downregulated HMGB1 mRNA and protein expression, reduced HMGB1 secretion, and inhibited TLR9 signaling pathways (TLR9 and MyD88) in PV-treated EAT rats and TFCs. Moreover, PV reversed the increases in the numbers of splenic Th1, Th2, and Th17 cells. Finally, our results acquired following administration of ethyl pyruvate, an HMGB1 inhibitor, to splenocytes cultured in vitro supported the hypothesis that the HMGB1/TLR9 pathway is involved in the PV-mediated reductions in Th1, Th2 and Th17 cells. Conclusion PV decreased the activity of the TLR9/MyD88 pathway and proinflammatory cytokines through HMGB1. In addition, we are the first to show that PV attenuated the HMGB1-induced increases in Th1, Th2 and Th17 cells in AIT models. These findings provide new evidence for the potential therapeutic value of PV as a treatment for AIT and other autoimmune diseases.

Abstract
Japanese encephalitis virus (JEV) is a mosquito-borne flavivirus, which causes the most commonly diagnosed viral encephalitis named Japanese encephalitis (JE) in the world with an unclear pathogenesis. Axl, a receptor tyrosine kinase from TAM family, plays crucial role in many inflammatory diseases. We have previously discovered that Axl deficiency resulted in more severe body weight loss in mice during JEV infection, which we speculate is due to the anti-inflammatory effect of Axl during JE. Currently, the role of Axl in regulating the neuroinflammation and brain damage during JE has not been investigated yet. In this study, by using Axl deficient and heterozygous control mice, we discovered that Axl deficient mice displayed accelerated JE progression and exacerbated brain damage characterized by increased neural cell death, extended infiltration of inflammatory cells, and enhanced production of pro-inflammatory cytokines, in comparison to control mice. Additionally, consistent with our previous report, Axl deficiency had no impact on the infection and target cell tropism of JEV in brain. Taken together, our results suggest that Axl plays an anti-inflammatory and neuroprotective role during the pathogenesis of JE.

Abstract
Correlation between periodontitis and atherosclerosis is well established, and the inherent mechanisms responsible for this relationship remain unclear. The biological function of growth arrest‐specific 6 (gas6) has been discovered in both atherosclerosis and inflammation. Inhibitory effects of gas6 on the expression of inflammatory factors in human umbilical vein endothelial cells (HUVECs) stimulated by Porphyromonas gingivalis lipopolysaccharide (P. gingivalis‐LPS) were reported in our previous research. Herein, the effects of gas6 on monocytes‐endothelial cells interactions in vitro and their probable mechanisms were further investigated. Gas6 protein in HUVECs was knocked down with siRNA or overexpressed with plasmids. Transwell inserts and co‐culturing system were introduced to observe chemotaxis and adhering affinity between monocytes and endothelial cells in vitro. Expression of gas6 was decreased in inflammatory periodontal tissues and HUVECs challenged with P. gingivalis‐LPS. The inhibitory effect of gas6 on chemotaxis and adhesion affinity between monocytes and endothelial cells was observed, and gas6 promoted Akt phosphorylation and inhibited NF‐κB phosphorylation. To our best knowledge, we are first to report that gas6 inhibit monocytes‐endothelial cells interactions in vitro induced by P. gingivalis‐LPS via Akt/NF‐κB pathway. Additionally, inflammation‐mediated inhibition of gas6 expression is through LncRNA GAS6‐AS2, rather than GAS6‐AS1, which is also newly reported.

Abstract
Survival rates after heart transplant have significantly improved over the last decade. Nevertheless, long-term allograft viability after 10 years remains poor and the sequelae of transplant-associated immunosuppression increases morbidity. Although several studies have implicated roles for lymphocyte-mediated rejection, less is understood with respect to non-major histocompatibility, and innate immune reactivity, which influence graft viability. As immature and mature dendritic cells (DCs) engage in both Major Histocompatibility Complex (MHC)-dependent and MHC-independent immune responses, these cells are at the crossroads of therapeutic strategies that seek to achieve both allograft tolerance and suppression of innate immunity to the allograft. Here we review emerging roles of DC subsets and their molecular protagonists during allograft tolerance and allograft rejection, with a focus on cardiac transplant. New insight into emerging DC subsets in transplant will inform novel strategies for operational tolerance and amelioration of cardiac vasculopathy.

Abstract
BACKGROUND Celastrol (Cel) has been corroborated as an anti-inflammatory and anti-apoptotic agent in multiple cell damage models. However, the protective effect of Cel in high glucose (HG)-induced cardiomyocyte injury is still unclear. The present study aimed to determine whether Cel can mitigate HG-stimulated cardiomyocyte injury via regulating the miR-345-5p/growth arrest-specific 6 (Gas6) signaling pathway. METHODS Cardiomyocytes were exposed to normal glucose (NG; 5 mmol/l) or HG (30 mmol/l) and then administered with Cel. Cell counting kit-8 and flow cytometry assays were used to detect cell proliferative activity and apoptosis. mRNA and protein expression were analyzed using a quantitative reverse transcriptase-polymerase chain reaction and western blotting, respectively. A bioinformatics algorithm and a luciferase reporter gene assay were used to determine whether Gas6 is a direct target of miR-345-5p. RESULTS The present study confirmed the inhibitory effects of Cel in HG-induced inflammation in cardiomyocytes. Moreover, Cel exhibited the ability to antagonize HG-induced cardiomyocyte apoptosis and suppress the elevated Bax/Bcl-2 ratio elicited by HG stimulation. Intriguingly, Cel treatment revoked the HG-triggered repression of Gas6 protein expression, and Gas6 loss-of-function accelerated HG-induced cardiomyocyte apoptosis. HG-triggered up-regulation of miR-345-5p expression was depressed following Cel treatment. Importantly, we validated that Gas6 is a direct target of miR-345-5p. Transfection with miR-345-5p inhibitors restrained HG-induced release of pro-inflammatory cytokines and cell apoptosis. CONCLUSIONS The findings of the present study demonstrate that Cel administration antagonized HG-induced cardiomyocyte apoptosis and inflammation through up-regulating Gas6 expression by restraining miR-345-5p.
