Single‐Cell RNA Sequencing Informs Precision Targeting of Monogenic Lupus Associated With IKZF1 Haploinsufficiency

Arthritis &Rheumatology, EarlyView.
Objective This study aimed to investigate the mechanisms of immune dysregulation in a pediatric patient with monogenic lupus driven by IKZF1 haploinsufficiency. Methods Peripheral immune cells from a patient with IKZF1 haploinsufficiency, patients with lupus with no currently known genetic mutations, and healthy controls were analyzed using single‐cell

Integrative single cell RNA‐sequencing and spatial transcriptomics uncovers distinct macrophage‐fibroblast cross‐talk in human hip synovium between patients with femoroacetabular impingement and osteoarthritis

Arthritis &Rheumatology, Accepted Article.
Objectives Femoroacetabular impingement (FAI) and synovitis have been recognized as essential factors for developing osteoarthritis (OA) in the hip joints. However, little is known about altered synovial cellular compositions, their associated transcriptomic profiles, and cell‐cell interactions in FAI and hip OA.

Efficacy and Safety of Subcutaneous Anifrolumab in Systemic Lupus Erythematosus: A Randomized, Phase 3 Study

Arthritis &Rheumatology, EarlyView.
Objective The multinational, phase 3, double‐blind, placebo‐controlled TULIP‐SC trial evaluated the efficacy and safety of subcutaneous anifrolumab in adults who have moderate to severe systemic lupus erythematosus (SLE) activity, despite receiving standard therapy. Methods Adults with SLE received subcutaneous anifrolumab 120 mg or placebo once weekly

Dysregulation of U12‐Type Splicing in Lupus Neutrophils

Arthritis &Rheumatology, EarlyView.
Objective Neutrophil dysfunction is a hallmark of systemic lupus erythematosus (SLE), but its molecular basis remains unclear. This study explores transcriptional and posttranscriptional changes in low‐density granulocytes (LDGs), a proinflammatory neutrophil subset expanded in SLE, focusing on NADPH oxidase (Nox) function and minor intron splicing ...

OGFRL1 Deficiency Causes Chronic Recurrent Multifocal Osteomyelitis Via Pathologic Osteoclastogenesis, With Therapeutic Response to Tumor Necrosis Factor Inhibitor

Arthritis &Rheumatology, EarlyView.
Objective To verify the pathogenesis of the opioid growth factor receptor like‐1 (OGFRL1) loss‐of‐function variant (c.30del, p. F10Ffs*110) identified in a patient with chronic recurrent multifocal osteomyelitis (CRMO) and to investigate the underlying mechanism.

Multi‐Omic Profiling Reveals Immune Cell Priming Signature Linked to Lupus Prognosis

Arthritis &Rheumatology, EarlyView.
Objective Systemic lupus erythematosus (SLE) is a multiorgan disease with widespread immune dysregulation and significant unmet clinical need. Blood‐based gene expression studies have advanced our understanding of SLE pathogenesis but may overlook critical tissue‐specific mechanisms that drive disease heterogeneity and progression.
