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.

Impact of HLA antigen and antibody expression on cross-matching and transfusion effect

Zhongguo shuxue zazhi
[Objective] To study the relationship between the expression intensity of HLA-Ⅰ platelet antibodies in patients with platelet transfusion refractoriness (PTR) and platelet cross-matching, and to further evaluate other factors in order to provide relevant

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.

HLA-DP antibodies before and after renal transplantation.

, 2010
Human leukocyte antigen (HLA)-DP is considered a target for humoral immune response in clinical transplantation. This study analyses the incidence of HLA-DP antibodies in renal patients.

Type I Interferon Drives Dysfunction of a Distinct CD8+ HLA‐DRB1+ T Cell Subset in Systemic Lupus Erythematosus

Arthritis &Rheumatology, EarlyView.
Objective Systemic lupus erythematosus (SLE) is characterized by type I interferon (IFN) signaling and adaptive immune dysregulation. We previously identified hypomethylation of HLA‐DRB1 and STAT1 in SLE CD8+ T cells, enabling aberrant IFN‐driven HLA‐DRB1 expression and expansion of a distinct CD8+ T cell subset. This study characterized CD8+ HLA‐DRB1+

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 ...

The HLA-DRA*0102 allele: correct nucleotide sequence and associated HLA haplotypes

, 2002
Here we correct the nucleotide sequence of a single known variant of the HLA-DRA gene. We show that the coding regions of the HLA-DRA*0101 and HLA-DRA*0102 alleles do not differ at two codons as reported previously, but only in codon 217.

Plasma Proteome Reflects Tissue Damage and Clinical Manifestations in Patients With Inflammatory Myopathies

Arthritis &Rheumatology, EarlyView.
Objective Tissue‐specific biomarkers that are reliable and associated with clinical manifestations of idiopathic inflammatory myopathy (IIM) are lacking. The blood circulation in individuals serves as a central conduit, allowing communication between tissues and facilitating clearance and recycling of tissue‐derived proteins.

Single‐Cell RNA Sequencing of Peripheral Blood Defines Two Immunologic Subtypes of Sjögren's Disease Distinguished by Anti‐SSA Antibodies and Aberrant B Cell Populations

Arthritis &Rheumatology, EarlyView.
Objective 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.

The synergistic impact of granulocytic myeloid‐derived suppressor cells and innate lymphoid cells in systemic sclerosis

Arthritis &Rheumatology, Accepted Article.
Objective Systemic sclerosis (SSc) is a chronic autoimmune disorder characterized by immune dysregulation and fibrosis, with myeloid‐derived suppressor cells (MDSCs) emerging as important regulators of immune responses. However, the role of MDSCs in SSc‐associated fibrosis and their interactions with other immune cell populations remain poorly ...
