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

A Cooperative Release of Mitochondrial DNA From Platelets and Neutrophils Drives an Interferon Signature in Systemic Sclerosis

Arthritis &Rheumatology, EarlyView.
Objective Mitochondria are organelles with a hypomethylated circular genome. Mitochondrial DNA (mtDNA) in the systemic circulation has been implicated in inflammation. This study investigates the role of circulating DNA in systemic sclerosis (SSc) and the cellular mechanisms governing its release.

Dual Action of Dipyridamole in Experimental Rheumatoid Arthritis: Suppression of Joint Inflammation and Upregulation of Muscle Anabolism via Adenosine and AMPK Pathways

Arthritis &Rheumatology, EarlyView.
Objective Rheumatoid sarcopenia, characterized by the progressive loss of skeletal muscle mass and function, is a frequent comorbidity in rheumatoid arthritis (RA), linked to prolonged, severe systemic inflammation. Purinergic signaling (adenosine, AMP, and ATP) plays a crucial role in inflammation, myogenesis, and muscle hypertrophy.

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.

A Multifaceted Interplay Among Hemophagocytosis, Interleukin‐18, and Type I Interferon Distinguishes Still Disease From Other Autoinflammatory Diseases

Arthritis &Rheumatology, EarlyView.
Objective The unknown pathophysiology and the lack of specific features for systemic juvenile idiopathic arthritis and adult‐onset Still disease (collectively known as Still disease; SD) delay diagnosis and appropriate treatment. The goal of this study was to identify features and mechanisms that distinguish SD from other systemic autoinflammatory ...

Long Noncoding RNA H19 Mediates STAT3‐Dependent Activation of Keratinocytes and Fibroblasts in Systemic Sclerosis Skin

Arthritis &Rheumatology, EarlyView.
Objective Dermal systemic sclerosis (SSc) fibroblasts and their exosomes can activate keratinocytes in SSc, with long noncoding RNA (lncRNA) H19 highlighted as the most up‐regulated RNA in their cargo compared with healthy controls (HCs). The role of H19 in SSc pathogenesis has never been investigated.

PEPITEM Regulates the Synovial Microenvironment During Immune‐Mediated Inflammatory Arthritis to Limit Disease

Arthritis &Rheumatology, EarlyView.
Objective Here we investigate the status of the adiponectin–PEPITEM pathway in early, treatment naive rheumatoid arthritis (RA) and psoriatic arthritis (PsA) and the therapeutic efficacy of PEPITEM administration in preclinical models. Methods Peripheral blood was isolated from patients with clinical suspect arthralgia and suspected inflammatory ...

Tissue Damage in Rheumatoid Arthritis Is Genetically Linked to Low Peptidylglycine Alpha‐Amidating Monooxygenase Activity in Synovial Fibroblasts

Arthritis &Rheumatology, EarlyView.
Objective Both susceptibility to, and severity of, rheumatoid arthritis (RA) is associated with the rs26232 C allele. Our primary aim was to identify the biologic mechanism underlying this association. Methods Expression of surrounding genes was compared among rs26232 genotypes.

A Rare RIPK3 Variant Enhances Necroptosis and Promotes Inflammation in a Still Disease–Like Autoinflammatory Syndrome

Arthritis &Rheumatology, EarlyView.
Objective Still disease represents a prototypical polygenic systemic autoinflammatory disease, characterized by recurrent systemic inflammation and dysregulation of innate immunity. Despite extensive clinical characterization, familial clustering Still disease remains unreported.
