Arthritis &Rheumatology, EarlyView.Objective Anti‐homocitrullinated protein/peptide antibodies are specific to rheumatoid arthritis (RA) and predictive of worse prognosis, suggesting a pathogenic role for autoreactivity to homocitrullinated peptides (HomoCitP). However, T cell responses to HomoCitP remain largely unexplored.

Arthritis &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.

Arthritis &Rheumatology, EarlyView.Objective Axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA) are overlapping yet distinct conditions within the SpA spectrum. As divergent immunophenotypes may influence disease course and therapeutic response, we compared immune cell subsets, cytokine profiles, and inflammatory mediators.

Arthritis &Rheumatology, EarlyView.Objective Although Takayasu arteritis (TAK) is not a prototypical autoantibody‐mediated disease, accumulating evidence suggests that B cells are involved. This study aimed to investigate the pathway of B cell activation and its contributions to TAK pathogenesis. Methods Histologic analysis of paravascular lymph nodes and affected arteries was conducted

Abatacept Reduces CD319+ (SLAMF7) Cytotoxic T Cells and Cytokine Production in Systemic Sclerosis
Arthritis &Rheumatology, EarlyView.Objective Systemic sclerosis (SSc) is characterized by immune dysregulation and fibrosis. We investigated whether abatacept modulates CD319/SLAMF7‐expressing cytotoxic T cells implicated in diffuse cutaneous SSc. Methods In this ancillary ASSET trial analysis, peripheral blood mononuclear cells from 67 participants were analyzed at baseline and months ...

Arthritis &Rheumatology, EarlyView.Objective CASTOR1 senses arginine and regulates mammalian target of rapamycin complex 1 (mTORC1), a central metabolic signaling molecule. This study aimed to elucidate the roles of CASTOR1 in humoral immune responses. Methods We analyzed human B cell transcriptomes from healthy controls and patients with systemic lupus erythematosus (SLE) via ...

Early Synovial Regulatory T Cell Engagement in Posttraumatic Osteoarthritis
Arthritis &Rheumatology, EarlyView.Objective Posttraumatic osteoarthritis (PTOA) develops despite restoration of joint biomechanics, suggesting that early postinjury biologic processes within the synovium shape disease trajectories. We investigated whether synovial Treg cells are engaged during the early phase following joint injury and whether experimental enrichment of this ...

Arthritis &Rheumatology, EarlyView.Graphical Abstract Objective This study aimed to characterize whole blood transcriptomic profiles in adults with active Sjögren's disease (SjD) treated with anti‐CD20 or B lymphocyte stimulator/BAFF inhibition, identify markers of clinical response, and define inflammatory pathways linked to nonresponse. Methods Whole blood RNA sequencing was performed

Arthritis &Rheumatology, EarlyView.Objective The gut–joint axis is a central paradigm in spondyloarthritis, yet the cellular mechanisms linking intestinal and joint immunity remain poorly understood. One potential link is T cell receptor αβ+ CD4+ colon intraepithelial lymphocytes (cIELs) that can traffic to extraintestinal tissues, including the joint.
