Abstract
IgG4-related disease (IgG4-RD) has complex clinical manifestations ranging from fibrosis and inflammation to deregulated metabolism. The molecular mechanisms underpinning these phenotypes are unclear. In this study, by using IgG4-RD patient peripheral blood mononuclear cells (PBMCs), IgG4-RD cell lines and Usp25 knockout mice, we show that ubiquitin-specific protease 25 (USP25) engages in multiple pathways to regulate fibrotic and inflammatory pathways that are characteristic to IgG4-RD. Reduced USP25 expression in IgG4-RD leads to increased SMAD3 activation, which contributes to fibrosis and induces inflammation through the IL-1β inflammatory axis. Mechanistically, USP25 prevents ubiquitination of RAC1, thus, downregulation of USP25 leads to ubiquitination and degradation of RAC1. Decreased RAC1 levels result in reduced aldolase A release from the actin cytoskeleton, which then lowers glycolysis. The expression of LYN, a component of the B cell receptor signalosome is also reduced in USP25-deficient B cells, which might result in B cell activation deficiency. Altogether, our results indicate a potential anti-inflammatory and anti-fibrotic role for USP25 and make USP25 a promising diagnostic marker and potential therapeutic target in IgG4-RD.

Abstract
Immunoglobulins are an essential part of the humoral immune response. IgG4 antibodies are the least prevalent subclass and have unique structural and functional properties. In this review, we discuss IgG4 class switch and B cell production. We review the importance of IgG4 antibodies in the context of allergic responses, helminth infections and malignancy. We discuss their anti-inflammatory and tolerogenic effects in allergen-specific immunotherapy, and ability to evade the immune system in parasitic infection and tumour cells. We then focus on the role of IgG4 autoantibodies and autoantigens in IgG4-autoimmune diseases and IgG4-related disease, highlighting important parallels and differences between them. In IgG4-autoimmune diseases, pathogenesis is based on a direct role of IgG4 antibodies binding to self-antigens and disturbing homeostasis. In IgG4-related disease, where affected organs are infiltrated with IgG4-expressing plasma cells, IgG4 antibodies may also directly target a number of self-antigens or be overexpressed as an epiphenomenon of the disease. These antigen-driven processes require critical T and B cell interaction. Lastly, we explore the current gaps in our knowledge and how these may be addressed.

Abstract
Immunoglobulin G4 (IgG4)-related disease is a chronic fibroinflammatory disease mediated by immune disorders. Given the challenging clinical diagnosis and treatment, knowledge of the pathogenesis of IgG4-related disease is important. The typical elevation of serum IgG4 concentrations and infiltration of IgG4-positive plasma cells in the involved tissues indicate the involvement of B lymphocytes in the pathogenesis of IgG4-related disease. Mass production of autoantibodies reflects abnormal activation of B cells, which causes tissue damage. Circulating plasmablasts are recently discovered markers that correlate with serum IgG4 concentration, the extent of organ involvement and disease activity. B-cell depletion therapy is an emerging curative strategy that can significantly alleviate clinical manifestations and achieve remission in patients with IgG4-related disease. These findings highlight the potential role of B cells in IgG4-related disease. In this review, we discuss the pathogenic impact of B lymphocytes on IgG4-related disease and describe novel therapies targeting B cells.

Abstract
OBJECTIVE We aimed to characterize the alterations in the immune phenotypes and explore the potential relevance to pathogenesis in IgG4-RD. METHODS Forty-two IgG4-RD patients and thirty-eight healthy controls were recruited in this study. Peripheral immunocompetent cells including T cells, CD4 + T cells, CD8 + T cells, B cells, NK cells CD4 + CD45RA + T cells (naïve T cells), CD4 + CD25 - / + Foxp3 - T cells (Teff), CD4 + CD25hiCD127lowCD161 + T cells (CD161 + Treg), CD4 + CD25hiFoxp3 + T cells (Foxp3 + Treg), CD4 + CD4RA-CXCR5 + PD1 + CCR7low T cells (pTfh), T helper (Th) 1, Th2, and Th17 before and after treatment were immunophenotyped by flow cytometry. RESULTS Compared with healthy controls, IgG4-RD patients showed higher proportions of NK (20.1% vs 13.6%, p < 0.01), Th1 (CD4 + IFN-γ + : 17.9% vs 14.2%, p = 0.061; TNF-α: 43.7% vs 36.7%, p < 0.05), Th2 (CD4 + IL-4 + : 2.4% vs 1.3%, p < 0.0001), CD161 + Treg (14.9% vs 11.6%, p < 0.01), pTfh (3.2% vs 2.4%, p < 0.05), and Foxp3 + Treg (8.3% vs 7.0%, p < 0.01) and lower proportions of B lymphocytes (8.4% vs 13.1%, p < 0.001), Teff (91.6% vs 92.6%, p < 0.01), and naïve Th cells (19.9% vs 32.1%, p < 0.01) before treatment. Foxp3 + Treg percentage decreased significantly after treatment (8.6% vs 6.9%, p < 0.05). Both serum C3 (r = - 0.6374, p < 0.01) and C4 (r = - 0.6174, p < 0.01) levels were in negative correlation with CD161 + Treg. The eosinophil percentage was positively correlated with Foxp3 + Treg (r = 0.5435, p < 0.05). Serum IgE level was positively correlated with Th2 (r = 0.5545, p < 0.05). There was a positive correlation between CD161 + Treg and pTfh (r = 0.4974, p < 0.05) while a negative correlation between Th2 and B cells (r = - 0.4925, p < 0.05). CONCLUSION Immune phenotypes were altered in IgG4-RD. Treg/Teff balance was shifted toward Treg in IgG4-RD. CD161 + Treg was likely to be involved in the pathogenesis of IgG4-RD. Key Points •Immune phenotypes were altered in B cells, T cells, and NK cells in IgG4-RD. •Treg/Teff balance was shifted toward Treg in IgG4-RD. •CD161+ Treg maybe play a proinflammatory role in IgG4-RD.

Abstract
Background The IgG4-related disease (IgG4-RD) is an immune-mediated disorder with fibrotic manifestations. However, the transcriptional profiles of immune cell subsets at single-cell level are unknown. Herein, single-cell sequencing was used to assess the specific cell subpopulations and pathways in peripheral blood mononuclear cells (PBMCs) of IgG4-RD. Methods Single-cell sequencing was performed using the PBMCs from four patients with IgG4-RD and three healthy controls (HCs). Functional enrichment and cell analysis were performed through re-clustering of PBMCs to assess functional pathways and intercellular communication networks in IgG4-RD. Western blot and flow cytometry were used to verify sequencing and functional enrichment results. Results Four major cell types and 21 subtypes were identified. Further subclustering demonstrated that plasma B-cell proportions increased with increasing glycolysis/gluconeogenesis activity in IgG4-RD. Re-clustering of myeloid cells showed that EGR1 and CD36 expressions were significantly increased in CD14+ monocytes of IgG4-RD, as validated by Western blot analysis. Moreover, tumor necrosis factor (TNF) production pathways were positively regulated in CD14+ monocytes of IgG4-RD. In vitro stimulation showed that CD14+ monocytes of IgG4-RD could secrete higher levels of TNF-α . Notably, the proportions of CD8 central memory T (TCM) and TIGIT+ CD8 cytotoxic T (CTL) increased in patients with IgG4-RD compared with HCs. Further interaction analysis showed that B cell activation factor (BAFF) signaling pathways were enriched from myeloid cells subsets to B cells. Conclusion This study enhances the understanding of the cellular heterogeneity and transcriptional features involved in the pathogenesis of IgG4-RD, providing key clinical implications.

Abstract
The establishment of precision medicine is considered particularly important in heterogeneous autoimmune diseases (e.g., psoriatic arthritis, systemic lupus erythematosus), which reveal clinical and molecular heterogeneity. The selection of optimal treatment strategies for individual patients may be more important and complex in autoimmune diseases than in other diseases. Two factors are important in precision medicine: patient stratification and use of targeted. When both factors work, patients are likely to have good outcomes. However, research into precision medicine and its practice in systemic autoimmune diseases is lacking. In contrast, the usefulness of peripheral immune cell phenotyping in the evaluation of immunological characteristics and stratification into subgroups of individual patients with systemic autoimmune diseases such as immunoglobulin 4-related disease, systemic lupus erythematosus, and anti-neutrophil cytoplasmic antibody-related vasculitis was reported. Furthermore, the potential of precision medicine using biological disease-modifying antirheumatic drugs based on peripheral immune cell phenotyping was recently demonstrated for psoriatic arthritis in the clinical setting. Precision medicine has not yet been sufficiently investigated in real world clinical settings. However, a dawn of precision medicine has emerged. We should shed further light on precision medicine in PsA and other autoimmune diseases. Here, we first review the usefulness of peripheral immune cell phenotyping in systemic autoimmune diseases and the potential of precision medicine in PsA based on this method.
