Kidney Hematopoietic Stem and Progenitor Cells Contribute to Myeloid Development and Pathology in Lupus Nephritis

open access: yesArthritis &Rheumatology, EarlyView.
Objective The hematopoietic system maintains homeostasis by balancing myeloid and lymphoid cell production in the bone marrow (BM). In response to increased hematopoietic demand, extramedullary hematopoiesis (EMH) may occur in nonlymphoid organs. We investigated the role of EMH and kidney‐resident hematopoietic stem and progenitor cells (HSPCs) in ...

Higher Complement C4 Gene Copy Number Constitutes a Shared Genetic Risk Factor for Giant Cell Arteritis and IgA Vasculitis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Low copy number (CN) of complement C4 isoforms and high CN of retroviral HERV‐K elements are known risk factors for many immune‐mediated inflammatory diseases (IMIDs), often showing sex‐biased effects. Here, we assessed whether CN variation within the C4 gene contributes to giant cell arteritis (GCA) and IgA vasculitis (IgAV), two complex ...

The Role of IgM Anti‐acetylated Protein Antibodies and B Cells in the Origin of Antimodified Protein Autoimmunity in Rheumatoid Arthritis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Rheumatoid arthritis (RA) is characterized by anti‐modified protein antibodies (AMPAs), including anti‐citrullinated protein antibodies (ACPA), anti‐carbamylated protein antibodies (anti‐CarP), and anti‐acetylated protein antibodies (AAPA). In contrast to other AMPAs, AAPA IgM is found in healthy individuals, raising questions about its role ...

IgG Glycosylation‐Dependent CLEC7A Signaling Drives Podocyte Dysfunction in Lupus Nephritis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Lupus nephritis (LN) is a severe complication of systemic lupus erythematosus (SLE) that can lead to end‐stage kidney disease and increased mortality. IgG from patients with LN displays abnormal glycosylation, contributing to podocyte injury.

Increased Plasma Microbial tDR‐1 in At‐Risk Individuals Is Associated With Decreased Conversion to Clinical Rheumatoid Arthritis and Reduces an In Vitro Macrophage Type 1 Interferon Response

open access: yesArthritis &Rheumatology, EarlyView.
Objective Microbial small RNAs can regulate human genes. Higher plasma concentrations of microbial transfer RNA (tRNA)‐derived RNA‐1 (tDR‐1) were previously associated with lower rheumatoid arthritis (RA) disease activity. This study examined whether tDR‐1 concentrations differ in anticyclic citrullinated peptide‐3 positive (CCP3+) at‐risk individuals (

Dnmt3a Mutations Limit Normal and Autoreactive CD4+ T Follicular Helper Responses and Attenuate T Cell–Driven Joint Inflammation

open access: yesArthritis &Rheumatology, EarlyView.
Objective Somatic DNMT3A mutations are the most common drivers of clonal hematopoiesis in patients with rheumatoid arthritis (RA) and have been associated with seropositive disease and increased markers of inflammation. These mutations are predominantly hypomorphic or dominant‐negative, reducing DNMT3A function.
