Homocitrullinated Peptides Drive Pro‐Inflammatory T Cell Responses in a Humanized Mouse Model of Rheumatoid Arthritis

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.

Distinct Molecular Pathways Supporting Sjögren Disease Clusters and Disease Progression

Arthritis &Rheumatology, EarlyView.
Objective Sjögren disease (SjD) is a heterogeneous autoimmune disease. We aimed to investigate blood transcriptomic signatures and disease progression among three recently defined clusters of patients with SjD: (1) B cell active disease with low symptom burden (BALS), (2) high systemic activity (HSA), and (3) low systemic activity with high symptom ...

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

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.

Deep Immunophenotyping Reveals Distinct Immune Signatures in Axial Spondyloarthritis and Psoriatic Arthritis

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.

Age‐Associated B Cells Contribute to Inflammation Via Antibody‐Independent Mechanisms in Takayasu Arteritis

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 ...

Single‐cell RNA sequencing of peripheral blood defines two immunological subtypes of Sjögren's disease distinguished by anti‐SSA antibodies and aberrant B cell populations

Arthritis &Rheumatology, Accepted Article.
Objectives Sjögren's disease (SjD) is a heterogeneous autoimmune disorder characterized by substantial clinical and molecular diversity. This heterogeneity raises key questions regarding the existence of distinct pathogenic mechanisms underlying disease subtypes.

Status of oncology drugs with a conditional approval: A cross‐sectional comparison of the Food and Drug Administration and Health Canada

British Journal of Clinical Pharmacology, EarlyView.
Aims This study looks at the status of the same drugs conditionally approved by the Food and Drug Administration and Health Canada for the same oncology indication. Methods Lists of oncology drugs with a conditional approval from the Food and Drug Administration and Health Canada were generated and drug pairs with the same indication were matched ...
