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.

Screening of HLA antibodies in maternal sera from Hyderabad

, 1991
Antibodies against human leucocyte antigens (HLA) in sera from uni and multiparous women are the potential source of HLA reagent. The present study was undertaken to screen 169 sera from pregnant women for the presence of HLA antibodies employing 26 ...

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 ...

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.

各型乙型肝炎HLA-Ⅰ、Ⅱ类抗原免疫组织化学研究

, 1992
用免疫组织化学桥联酶标APAAP法和PAP法对各型乙型肝炎113例检测了肝内的HLA-Ⅰ、Ⅱ类抗原、T细胞亚群、HBsAg和HBcAg,同时测定血清HBV DNA（斑点杂交）和β2微球蛋白（RIA）。结果表明;急性肝炎、慢性活动性肝炎、重症肝炎患者的肝细胞HLA-Ⅰ、Ⅱ类抗原表达增强,尤以Ⅰ类抗原明显,慢性迁延性肝炎则几乎无表达。肝细胞HLA-Ⅰ类抗原表达与肝内炎症反应、肝细胞膜型HBSAg和浆膜型HBcAg关系密切,肝内活动性病变主要浸润细胞为CD2+细胞,CD0+细胞构成主要的细胞亚群 ...

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.
