Abstract
Sjogren's syndrome (SS) is a complex systemic autoimmune disease. This study aims to elucidate a humanized NOD-PrkdcscidIl2rgem1/Smoc (NSG) murine model to better clarify the pathogenesis of SS. NSG female mice were adoptively transferred with 10 million peripheral blood mononuclear cells (PBMCs) through the tail vein from healthy controls (HCs), primary Sjogren's syndrome (pSS), and systemic lupus erythematosus (SLE) patients on D0. The mice were subcutaneously injected with C57/B6j submandibular gland (SG) protein or phosphate-buffered saline on D3, D17 and D31, respectively. NSG mice were successfully transplanted with human PBMCs. Compared with NSG-HC group, NSG-pSS and NSG-SLE mice exhibited a large number of lymphocytes infiltration in the SG, decreased salivary flow rate, lung involvement, decreased expression of genes related to salivary secretion, and the production of autoantibodies. Type I interferon-related genes were increased in the SG of NSG-pSS and NSG-SLE mice. The ratio of BAX/BCL2, BAX, cleaved caspase3, and TUNEL staining were increased in the SG of NSG-pSS and NSG-SLE mice. The expressions of p-MLKL and p-RIPK3 were increased in the SG of NSG-pSS and NSG-SLE mice. Increased expression of type I interferon-related genes, PANoptosis (apoptosis and necroptosis) were identified in the SG of this typical humanized NSG murine model of SS.

Abstract
OBJECTIVE Celastrol is a bioactive constituent extracted from Tripterygium wilfordii (thunder god vine). It has been demonstrated to have a therapeutic effect on experimental disease models for chronic inflammatory and immune disorders. In the present study, we investigated whether and how celastrol exerts a regulatory effect on the autoimmune response in MRL/lpr mice. METHODS We performed an in vivo study to determine the therapeutic effects of celastrol in MRL/lpr mice and then further investigated the underlying mechanism of celastrol in the regulation of the autoimmune response in MRL/lpr mice. RESULTS Celastrol showed a therapeutic effect in MRL/lpr mice by preventing the enlargement of the spleen and lymph nodes, alleviating renal injury, and reducing the levels of ANA and anti-double-stranded DNA antibodies. Furthermore, celastrol suppressed the in vivo inflammatory response in MRL/lpr mice by reducing the serum levels of multiple cytokines, including interleukin (IL)-6, tumour necrosis factor (TNF) and interferon (IFN)-γ, and the production of multiple antibody subsets, including total IgG, IgG1 and IgG2b. In vitro, celastrol reduced anti-CD3 antibody stimulation-induced T helper 1 and TNF-producing cells in CD4+ T cells of MRL/lpr mice. In addition, celastrol significantly affected B cell differentiation and prevented the generation of plasma cells from B cells in MRL/lpr mice by reducing the frequency of activated and germinal centre B cells. Celastrol treatment also affected T cell differentiation and significantly reduced central memory T cell frequencies in MRL/lpr mice. Importantly, celastrol treatment specifically promoted apoptosis of CD138+ but not CD138- T cells to suppress autoimmune T cell accumulation in MRL/lpr mice. CONCLUSIONS Celastrol exerted therapeutic effects on lupus by specifically promoting apoptosis of autoimmune T cells and preventing the progression of autoimmune response.

Abstract
Central nervous system (CNS) pathologies are a public health concern, with viral infections one of their principal causes. These viruses are known as neurotropic pathogens, characterized by their ability to infiltrate the CNS and thus interact with various cell populations, inducing several diseases. The immune response elicited by neurotropic viruses in the CNS is commanded mainly by microglia, which, together with other local cells, can secrete inflammatory cytokines to fight the infection. The most relevant neurotropic viruses are adenovirus (AdV), cytomegalovirus (CMV), enterovirus (EV), Epstein-Barr Virus (EBV), herpes simplex virus type 1 (HSV-1), and herpes simplex virus type 2 (HSV-2), lymphocytic choriomeningitis virus (LCMV), and the newly discovered SARS-CoV-2. Several studies have associated a viral infection with systemic lupus erythematosus (SLE) and neuropsychiatric lupus (NPSLE) manifestations. This article will review the knowledge about viral infections, CNS pathologies, and the immune response against them. Also, it allows us to understand the relevance of the different viral proteins in developing neuronal pathologies, SLE and NPSLE.

Abstract
BACKGROUND Cuproptosis is a novel mode of cell death, which is strongly related to energy metabolism in mitochondria and regulated by protein lipoylation. Currently, the molecular mechanisms of cuproptosis-related genes (CRGs) involved in systemic lupus erythematosus (SLE) largely remained unclear, our study is aimed to explore the mechanisms of cuproptosis and CRGs involved in SLE. METHODS Bulk RNA-seq datasets were collected to display the expressions of CRGs in peripheral blood mononuclear cells (PBMCs) of SLE and healthy individuals, and then ROC analysis was used to establish the diagnostic models of CRGs. Next, the immune infiltration analyses were applied to reveal the difference of immune cells infiltration in LIAS-low and LIAS-high group. Additionally, WGCNA analysis was performed to find the gene modules significantly correlated with the LIAS expression level. We also performed the functional enrichment analyses for LIAS-related gene modules to determine the potential pathways involved in the development of SLE. Finally, scRNA-seq dataset was used to cluster immune cell subsets, reveal the activated pathways, and study cell-cell interactions in LIAS-low and LIAS-high cells. RESULT We found CDKN2A was significantly increased and LIAS was significantly decreased in SLE patients compared with healthy individuals. The AUC score showed that LIAS had a great diagnostic value than other CRGs. Additionally, the results of immune infiltration analyses showed that immune cells proportion were diverse in LIAS-low and LIAS-high samples. The gene sets related to LIAS expression level were involved in dephosphorylation of JAK1 by SHP1, phosphorylation of STAT2, cytokine signaling in immune system, expression of interferon-alpha and beta, inhibition of JAK kinase activity by SOCS1/3, and so on. Finally, the results of cell-cell communication showed that CCL- (CCL5 + CCR1) and ANNEXIN- (ANXA1 + FPR1) might play an essential role in the communication network between LIAS-low and LIAS-high cells. CONCLUSION Above findings inferred that LIAS-mediated cuproptosis might involve in a comprehensive cellular and molecular mechanism to cause the occurrence and development of SLE.

JOURNAL OF ETHNOPHARMACOLOGY 2023; 312:116329. [PMID: 36940737 DOI: 10.1016/j.jep.2023.116329] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/10/2022] [Revised: 02/18/2023] [Accepted: 02/23/2023] [Indexed: 05/08/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Traditional Chinese medicine believes that "blood fever" is an important cause of psoriasis. Fufang Shengdi mixture (FFSD), based on the Hongban Decoction, is composed of Rehmannia glutinosa (Gaertn.) DC., Raw gypsum (Chinese: Sheng Shi Gao), and Lonicera japonica Thunb (Caprifoliaceae). FFSD has effects on nourishing Yin, clearing heat, connecting collaterals, and cooling blood. In modern medical explanation, FFSD has the effects of anti-inflammatory and immunosuppression. Our study proved that FFSD can suppress immunity and ameliorate the symptoms of imiquimod-induced psoriasis in mice. AIM OF THE STUDY This study evaluated the efficacy and possible mechanism of FFSD in psoriasis mice. METHODS AND MATERIALS First, the main components of FFSD were analyzed using high-performance liquid chromatography-tandem high-resolution mass spectrometry (HPLC-HRMS). An imiquimod (IMQ)-induced psoriasis mouse model was used to evaluate the efficacy of FFSD orally. Psoriasis area and severity index (PASI) scores were recorded throughout the course of the mice to reflect the severity of psoriasis. Hematoxylin-eosin staining was used to observe the pathological changes in skin lesions. Enzyme-linked immunosorbent assay (ELISA) was performed to test the level of IFN-γ and TNF-α in plasma. To further investigate the immunopharmacological effect of FFSD, we used chicken ovalbumin (OVA) to induce immunoreaction in mice. ELISA was used to detect the levels of anti-OVA antibody, IFN-γ and TNF-α in mice. Flow cytometry was performed to quantify the ratio of cell types in peripheral blood mononuclear cells (PBMCs) to evaluate the effect of FFSD on immunosuppression. Proteomics and bioinformatics analyzes were performed to find the regulation pathway of the immunosuppressive effect of FFSD. Finally, quantitative PCR (qPCR) and immunohistochemistry were used to measure the upregulation of Annexin-A proteins (ANXAs) in the skin lesion tissue of IMQ-induced mouse. RESULTS On the basis of knowing the composition of FFSD, we first proved the efficacy of FFSD in alleviating IMQ-induced psoriasis in mice. Second, we further clarified the pharmacological effect of FFSD on immunosuppression via OVA-induced mice. Subsequently, it was found that the significant up-regulation of ANXAs was caused by FFSD through proteomics analysis, and the finding was proved in the IMQ-induced psoriasis mouse model. CONCLUSIONS This study elucidates the immunosuppressive pharmacological effect of FFSD on improving psoriasis through up-regulating ANXAs.

Abstract
BACKGROUND Systemic lupus erythematosus (SLE) is a prototypic autoimmune disease mainly mediated by IgG autoantibody. While follicular helper T (Tfh) cells are crucial for supporting IgG autoantibody generation in human SLE, underlying mechanisms for Tfh cell mal-differentiation remain unclear. METHODS In total, 129 SLE patients and 37 healthy donors were recruited for this study. Circulating leptin was determined by ELISA from patients with SLE and healthy individuals. CD4 T cells isolated from SLE patients and healthy donors were activated with anti-CD3/CD28 beads under cytokine-unbiased conditions in the presence or absence of recombinant leptin protein, followed by detection for Tfh cell differentiation by quantifying intracellular transcription factor Bcl-6 and cytokine IL-21. AMPK activation was assessed by analyzing phosphor-AMPK using phosflow cytometry and immunoblots. Leptin receptor expression was determined using flow cytometry and its overexpression was achieved by transfection with an expression vector. Humanized SLE chimeras were induced by injecting patients' immune cells into immune-deficient NSG mice and used for translational studies. RESULTS Circulating leptin was elevated in patients with SLE, inversely associated with disease activity. In healthy individuals, leptin efficiently inhibited Tfh cell differentiation through inducing AMPK activation. Meanwhile, leptin receptor deficiency was a feature of CD4 T cells in SLE patients, impairing the inhibitory effect of leptin on the differentiation of Tfh cells. As a result, we observed the coexistence of high circulating leptin and increased Tfh cell frequencies in SLE patients. Accordingly, overexpression of leptin receptor in SLE CD4 T cells abrogated Tfh cell mal-differentiation and IgG anti-dsDNA generation in humanized lupus chimeras. CONCLUSION Leptin receptor deficiency blocks the inhibitory effect of leptin on SLE Tfh cell differentiation, serving as a promising therapeutic target for lupus management.

Abstract
Der p 1 is one of the major allergenic molecules of Dermatophagoides pteronyssinus, causing house dust mite (HDM) allergy. The pathological B cells produce allergen-specific IgE antibodies that mediate the hypersensitivity reaction, therefore the selective elimination of these B cells is a legitimate therapeutic goal in allergy. Chimeric molecule Dp51-72 able to cross-link B cell inhibitory complement receptor type 1 and BCR on Der p 1-specific B cells was constructed. The signalling capabilities of this molecule have been tested on human B cells. A humanized mouse model of HDM allergy has been used to test the in vivo effects of the chimeric molecule administration. Administering the chimeric molecule to immunodeficient Rag2- γc- mice transferred with PBMCs from allergic patients resulted in reduction of allergen-specific IgE antibodies in the sera, and reduced infiltration of immune cells in lung histology preparations. Reduced numbers of human CD45+ and CD4+ cells in the lungs as well as inhibition of mast cell degranulation were also observed. The treatment with Dp51-72 chimera significantly decreased the local levels of anti-Dpt IgE antibodies in the bronchoalveolar lavage fluid (BALF). The binding of the chimeric molecule to tonsillar B cells triggers the tyrosine phosphorylation of 30-32 kDa protein, which is most likely involved in the inhibitory process. Administration of constructed chimeric molecules to humanized mice with developed inflammation resulted in specific suppression of disease-associated IgE antibody-producing cells and preserved lung histology. This effective approach could be further developed into a therapeutic agent for treatment of patients with HDM allergy.

Abstract
Myeloid-derived suppressor cells (MDSCs) are a group of immature myeloid cells that play an important role in diseases. MDSCs promote Th17 differentiation and aggravate systemic lupus erythematosus (SLE) progression by producing arginase-1 to metabolize arginine. However, the metabolic regulators remain unknown. Here, we report that MDSC derivative polyamines can promote Th17 differentiation via miR-542-5p in vitro. Th17 polarization was enhanced in response to polyamine treatment or upon miR-542-5p overexpression. The TGF-β/SMAD3 pathway was shown to be involved in miR-542-5p-facilitated Th17 differentiation. Furthermore, miR-542-5p expression positively correlated with the levels of polyamine synthetases in peripheral blood mononuclear cells of patients with SLE as well as disease severity. In humanized SLE model mice, MDSC depletion decreased the levels of Th17 cells, accompanied by reduced expression of miR-542-5p and these polyamine synthetases. In addition, miR-542-5p expression positively correlated with the Th17 level and disease severity in both patients and humanized SLE mice. Together, our data reveal a novel molecular pathway by which MDSC-derived polyamine metabolism enhances Th17 differentiation and aggravates SLE.

Abstract
Fibromyalgia (FM) is an idiopathic chronic disease characterized by widespread musculoskeletal pain, hyperalgesia and allodynia, often accompanied by fatigue, cognitive dysfunction and other symptoms. Autoimmunity and neuroinflammatory mechanisms have been suggested to play important roles in the pathophysiology of FM supported by recently identified interferon signatures in affected individuals. However, the contribution of different components in the immune system, such as the B-lymphocytes, in the progression to FM are yet unknown. Furthermore, there is a great need for biomarkers that may improve diagnostics of FM. Herein, we investigated the gene expression profile in peripheral B-cells, as well as a panel of inflammatory serum proteins, in 30 FM patients and 23 healthy matched control individuals. RNA sequence analysis revealed 60 differentially expressed genes when comparing the two groups. The group of FM patients showed increased expression of twenty-five interferon-regulated genes, such as S100A8 and S100A9, VCAM, CD163, SERPINA1, ANXA1, and an increased interferon score. Furthermore, FM was associated with elevated levels of 19 inflammatory serum proteins, such as IL8, AXIN1, SIRT2 and STAMBP, that correlated with the FM severity score. Together, the results shows that FM is associated with an interferon signature in B-cells and increased levels of a set of inflammatory serum proteins. Our findings bring further support for immune activation in the pathogenesis of FM and highlight candidate biomarkers for diagnosis and intervention in the management of FM.

Abstract
As medical and pharmacological technology advances, new and complex modalities of disease treatment that are more personalized and targeted are being developed. Often these modalities must be validated in the presence of critical components of the human biological system. Given the incongruencies between murine and human biology, as well as the human-tropism of certain drugs and pathogens, the selection of animal models that accurately recapitulate the intricacies of the human biological system becomes more salient for disease modeling and preclinical testing. Immunodeficient mice engrafted with functional human tissues (so-called humanized mice), which allow for the study of physiologically relevant disease mechanisms, have thus become an integral aspect of biomedical research. This review discusses the recent advancements and applications of humanized mouse models on human immune system and liver humanization in modeling human diseases, as well as how they can facilitate translational medicine.

Abstract
Dying mammalian cells emit numerous signals that interact with the host to dictate the immunological correlates of cellular stress and death. In the absence of reactive antigenic determinants (which is generally the case for healthy cells), such signals may drive inflammation but cannot engage adaptive immunity. Conversely, when cells exhibit sufficient antigenicity, as in the case of infected or malignant cells, their death can culminate with adaptive immune responses that are executed by cytotoxic T lymphocytes and elicit immunological memory. Suggesting a key role for immunogenic cell death (ICD) in immunosurveillance, both pathogens and cancer cells evolved strategies to prevent the recognition of cell death as immunogenic. Intriguingly, normal cells succumbing to conditions that promote the formation of post-translational neoantigens (for example, oxidative stress) can also drive at least some degree of antigen-specific immunity, pointing to a novel implication of ICD in the etiology of non-infectious, non-malignant disorders linked to autoreactivity.

Abstract
Animal models have played a crucial role in the understanding of the mechanisms and treatments of human diseases; however, owing to the large differences in genetic background and disease-specific characteristics, animal models cannot fully simulate the occurrence and progression of human diseases. Recently, humanized immune system mice, based on immunodeficient mice, have been developed that allow for the partial reconstruction of the human immune system and mimic the human in vivo microenvironment. Systemic lupus erythematosus (SLE) is a complex disease characterized by the loss of tolerance to autoantigens, overproduction of autoantibodies, and inflammation in multiple organ systems. The detailed immunological events that trigger the onset of clinical manifestations in patients with SLE are still not well known. Two methods have been adopted for the development of humanized SLE mice. They include transferring peripheral blood mononuclear cells from patients with SLE to immunodeficient mice or transferring human hematopoietic stem cells to immunodeficient mice followed by intraperitoneal injection with pristane to induce lupus. However, there are still several challenges to be overcome, such as how to improve the efficiency of reconstruction of the human B cell immune response, how to extend the lifespan and improve the survival rate of mice to extend the observation period, and how to improve the development of standardized commercialized models and use them. In summary, there are opportunities and challenges for the development of humanized mouse models of SLE, which will provide novel strategies for understanding the mechanisms and treatments of SLE.

Abstract
OBJECTIVE Histone modification is an epigenetic alteration which either activates or suppresses gene transcription. Studies revealed the association of altered global histone modification in T cells and monocytes with the pathogenesis of Systemic lupus erythematosus (SLE). Herein, we investigated the level of global histone 3 (H3) and histone 4 (H4) acetylation in B cells of SLE patients. METHODS Total 20 SLE patients and 10 healthy donors were recruited. Global H3 and H4 acetylation in B cells was assessed by Epigentek assay kits. Expression of DNA methyltransferase 1 (DNMT1) in B cells was analyzed by staining cells with anti-CD19/20 and anti-DNMT1 antibody. The concentration of BAFF and APRIL was measured using LegendPlex Human B cells panel and circulating ANAs were determined using indirect immunofluorescence. RESULTS Compared to healthy donors, B cells from SLE patients were found to be hypoacetylated on both H3 and H4 histones together with a decrease in the expression of DNMT1. Indeed, stratification of SLE patients on the basis of disease activity did not show any variation, as the amount of H3 and H4 acetylation in both inactive and active SLE patients was almost uniform. CONCLUSION These findings suggest that SLE-B cells were manifested with aberrant histone acetylation levels.

Abstract
Systemic lupus erythematosus (SLE) is a severe autoimmune disease characterized by dysfunction of immune regulation, overproduction of inflammatory cytokines and attack on normal tissues by self-reactive cells and antibodies. The main role in the pathogenesis plays the autoreactive tandem of B-T cells, responsible for lupus progression and acceleration. Both activated B and T cells express a phospholipid binding protein Annexin A1 and abnormal levels of the protein were found in murine and human autoimmune syndromes, potentiating its role as a therapeutic target. Here, using anti-annexin A1 antibody we explore its property to modulate the autoimmune response in MRL/lpr mouse model of lupus. Anti-ANX A1 antibody was tested in vitro using spleen cells from MRL/lpr mice to determine the effect on lymphocyte activation, plasma cells differentiation, apoptosis and proliferation by flow cytometry and ELISpot assays. Subsequently, several groups of young (disease-free) and old (sick) MRL/lpr mice were treated with the antibody to determine the levels of panel auto-antibodies and cytokines, T cell arrest and migration. Treatment of splenocytes with anti-ANX A1 antibody inhibited T-cell activation and proliferation, suppressed anti-dsDNA antibody-producing plasma cells and affected B cell apoptosis. Administration of the antibody to MRL/lpr mice resulted to decreased autoantibody levels to various lupus antigens, suppressed T cell migration from lymph nodes and increased the levels of IL4 mRNA compared to the control group. Anti-ANX A1 antibody therapy suppresses B and T cell over-activation and down- modulates disease activity.

Abstract
Systemic lupus erythematosus (SLE) is a chronic complex systemic autoimmune disease characterized by multiple autoantibodies and clinical manifestations, with the potential to affect nearly every organ. SLE treatments, including corticosteroids and immunosuppressive drugs, have greatly increased survival rates, but there is no curative therapy and SLE management is limited by drug complications and toxicities. There is an obvious clinical need for safe, effective SLE treatments. A promising treatment avenue is to restore immunological tolerance to reduce inflammatory clinical manifestations of SLE. Indeed, recent clinical trials of low-dose IL-2 supplementation in SLE patients showed that in vivo expansion of regulatory T cells (Treg cells) is associated with dramatic but transient improvement in SLE disease markers and clinical manifestations. However, the Treg cells that expanded were short-lived and unstable. Alternatively, antigen-specific tolerance (ASIT) approaches that establish long-lived immunological tolerance could be deployed in the context of SLE. In this review, we discuss the potential benefits and challenges of nanoparticle ASIT approaches to induce prolonged immunological tolerance in SLE.

Abstract
Routine manipulation of the mouse genome has become a landmark in biomedical research. Traits that are only associated with advanced developmental stages can now be investigated within a living organism, and the in vivo analysis of corresponding phenotypes and functions advances the translation into the clinical setting. The annexins, a family of closely related calcium (Ca2+)- and lipid-binding proteins, are found at various intra- and extracellular locations, and interact with a broad range of membrane lipids and proteins. Their impacts on cellular functions has been extensively assessed in vitro, yet annexin-deficient mouse models generally develop normally and do not display obvious phenotypes. Only in recent years, studies examining genetically modified annexin mouse models which were exposed to stress conditions mimicking human disease often revealed striking phenotypes. This review is the first comprehensive overview of annexin-related research using animal models and their exciting future use for relevant issues in biology and experimental medicine.

Abstract
Systemic lupus erythematosus is an autoimmune syndrome characterized by the development of autoantibodies to a wide range of antigens. Together with B cells, respective self-reactive T cells have an important contribution in disease progression as being responsible for inflammatory cytokines secretion, B cell activation and promoting amplification of the autoimmune response. Annexin A1 is expressed by many cell types and binds to phospholipids in a Ca2+ -dependent manner. Abnormal expression of annexin A1 was found on activated B and T cells in both murine and human autoimmunity suggesting its potential role as a therapeutic target. In the present study, we have investigated the possibility to suppress autoimmune manifestation in spontaneous mouse model of lupus using anti-annexin A1 antibody. Groups of lupus-prone MRL/lpr mice were treated with the anti-annexin A1 monoclonal antibody, and the disease activity and survival of the animals were following up. Flow cytometry, ELISA assays, and histological and immunofluorescence kidney analyses were used to determine the levels of Annexin A1 expression, cytokines, anti-dsDNA antibodies and kidney injuries. The administration of this monoclonal antibody to MRL/lpr mice resulted in suppression of IgG anti-dsDNA antibody production, modulated IL-10 secretion, decreased disease activity and prolonged survival compared with the control group.
