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

Arthritis &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

Arthritis &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 ...

From Interferon Signature to the Clinical Landscape: Type I Interferonopathies

Arthritis &Rheumatology, Accepted Article.
Background Type I interferonopathies are heterogeneous diseases driven by dysregulated IFN‐I signaling. Diagnosis is challenging due to clinical/molecular variability and the need for IFN‐I quantification. Objective To characterize the clinical, immunological, genetic, molecular profiles of patients with suspected enhanced IFN‐I signaling, and assess ...

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

Arthritis &Rheumatology, Accepted Article.
Background Lupus nephritis (LN) is a severe complication of systemic lupus erythematosus (SLE) that can lead to end‐stage kidney disease and increased mortality. Immunoglobulin G (IgG) from LN patients displays abnormal glycosylation, contributing to podocyte injury.
