Summary: AAV is a serious autoimmune disease characterized by vascular necrosis. The pathogenesis involves ANCA-mediated neutrophil activation, NETs formation, and a vicious cycle of NETs and ANCA production. Understanding the molecular signaling pathways in aberrant neutrophil activation and NETs clearance systems may lead to specific therapeutics for AAV. Standard therapy with glucocorticoids and immunosuppressants has improved outcomes, but targeted therapies for neutrophil activation and NETs clearance are potential alternatives.

Summary: This study aims to investigate the level and nature of circulating DNA in ANCA-associated vasculitis (AAV) and evaluate the clinical utility of DNA quantification. It was found that mtDNA, but not nDNA, is elevated in the plasma of AAV patients and correlated with disease activity. mtDNA quantification could be a superior biomarker in the laboratory monitoring of AAV activity.

Summary: Research has shown that NETs contribute to the pathogenesis of vasculitis through different mechanisms, including renal failure and vascular damage. The protective effects of NETs have also been highlighted. However, the role of neutrophil hyperactivity in vasculitis is not fully understood. More studies are needed to determine the accurate function of NETs in vasculitis pathogenesis.

Summary: The study aimed to investigate the involvement of neutrophil extracellular traps (NETs) in the pathogenesis of IgA vasculitis (IgAV) and their association with disease activity in children. Circulating levels of cf-DNA, MPO-DNA, and NE were significantly higher in onset and active IgAV patients compared to remission, drug withdrawal patients, and healthy controls. Our data suggest that NETs are released into the circulation of IgAV patients and may be used as a marker to assess disease severity in children with IgAV.

Summary: Patients with AAV have an increased risk of developing venous and arterial thrombotic events due to endothelial injury caused by neutrophil activation and NETs expression. Additionally, APLs and anti-plasminogen antibodies further contribute to thrombosis in AAV.

Summary: This study investigated the relationship between infiltrating citrullinated histone H3 (H3Cit)-positive neutrophils and disease specificity and activity in various glomerulonephritides. The presence of H3Cit+ neutrophils was found to be a potential marker for disease activity in antineutrophil cytoplasmic antibody-associated vasculitis (AAV).

Summary: Neutrophil extracellular traps (NETs) are involved in both infection control and tumor metastasis. The study by Mousset et al. published in Cancer Cell reveals that chemotherapy-induced inflammation promotes NETosis in malignant tumors, leading to chemoresistance. This finding highlights the potential of targeting inflammatory NETs for cancer treatment.

Summary: This study found that the glycosylation changes of IgG are associated with disease flares in patients with ANCA-associated vasculitis. In addition, among the glycosylation changes, alterations in Fc bisection and fucosylation levels of IgG are correlated with long-term treatment outcome and impending relapse.

Summary: Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a group of small vessel vasculitides characterized by granulomatous and neutrophilic tissue inflammation, often associated with the production of antibodies that target neutrophil antigens. AAV involves multiple organ systems clinically, including the lungs, kidneys, skin, and nervous system. The prognosis of AAV has significantly improved due to advances in understanding its pathogenesis and treatment options.

Summary: According to the study, the different ANCA serotypes in Chinese AAV patients have no impact on the likelihood of induced remission, patient survival, or disease recurrence. Younger patients with milder kidney involvement and lower disease assessment scores tend to have a better prognosis.

Summary: Glycosylation is a common modification that affects protein stability and interactions. It plays a significant role in rheumatic diseases, influencing inflammatory processes and disease progression. Understanding the impact of glycosylation on plasma proteins, cells, and tissues opens up potential interventions for the treatment of these diseases.

Summary: Since the publication of the EULAR recommendations for the management of AAV in 2016, several clinical trials have been conducted that have the potential to change clinical care. A systematic literature review and expert opinions were used to modify existing recommendations and create new ones. The recommendations provide updated guidance on AAV management.

Summary: In systemic lupus erythematosus, kidney involvement known as lupus nephritis is a serious condition with limited treatment options. This review analyzes current management guidelines, discusses emerging therapies, and explores the potential for precision medicine in treating lupus nephritis. Despite advancements, the prognosis for lupus nephritis has not significantly improved, and there are variations in treatment recommendations due to inter-ethnic differences and lack of evidence. New treatments and investigational drugs, such as calcineurin inhibitors and biologic agents, offer hope for improved outcomes. Molecular profiling and urine proteomic panels may help personalize treatment in the future.

Summary: Due to the challenge of dimensionality and limited training data, approximating high-dimensional functions is a difficult task. This paper introduces a new method called Dimension Reduction via Learning Level Sets (DRiLLS) for function approximation. The method uses a pseudoreversible neural network (PRNN) module to transform high-dimensional inputs to low-dimensional active variables, and a synthesized regression module to approximate function values in the low-dimensional space. Experimental results show that DRiLLS outperforms other methods, especially for target functions with critical points.

Summary: Autoimmune diseases are characterized by a breakdown of immunological tolerance to self, resulting in an abnormal immune response to self-antigens. The pathogenesis is driven by a complex interaction between autoreactive B and T cells. B cell targeting therapies, such as Rituximab, have shown efficacy in reducing symptoms of autoimmune diseases, but can also lead to infections. Therefore, antigen-specific approaches to target autoreactive cells are being investigated.

Summary: This study visualizes the B cell response against posttranslational modification antigens in autoimmune diseases. The results demonstrate extensive cross-reactivity of B cells against different antigens and the presence of PTM-directed plasmablasts in patients. The expression of CXCR3 suggests the potential involvement of chemokines in this process.

Summary: This study investigates the autoreactive B cell responses in ATA-positive and ACA-positive SSc patients. The results show that ATA-positive patients exhibit a more active B cell response, which is associated with the presence and severity of ILD. This may explain the differential responsiveness to B cell depleting therapy.

Summary: This study investigated the presence of different isotypes of anti-carbamylated protein (CarP) antibodies in systemic sclerosis (SSc) patients and its association with skin involvement. The results showed a higher prevalence of anti-CarP IgG in SSc patients compared to healthy controls, but no significant difference in the prevalence of IgA and IgM. Additionally, there was no significant correlation between the levels of anti-CarP antibodies and age or skin involvement.
