Autoreactivity Versus Autoimmunity: Characteristics of Autoantigen‐Specific CD4 T Cells in Rheumatoid Arthritis and Health

Arthritis &Rheumatology, EarlyView.
Objective CD4 T cells specific for citrullinated (cit) peptides are key players in rheumatoid arthritis (RA) immunopathogenesis. Characterizing these cells and identifying features of healthy and RA‐associated autoreactivity will provide valuable insight into disease mechanisms and form the basis of immune state biomarkers to facilitate the next ...

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.

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.

Protocol for measuring exogenous antigen presentation triggered by membranes of bone marrow-derived dendritic cell purified phagosomes

STAR Protocols
Summary: Dendritic cells are potent antigen-presenting cells that initiate T cell responses by presenting exogenous antigens associated with major histocompatibility complex (MHC) class I and MHC class II molecules.

Coexpression of neuronal, glial, and major histocompatibility complex class II antigens on retinoblastoma cells

, 1988
This study identifies the presence of major histocompatibility complex class II antigens on retinoblastoma cells. In addition, the modulation of HLA-DR by interferon-gamma as well as the preferential expression of this major histocompatibility complex ...

The transmembrane domain of the adenovirus E3/19K protein acts as an ER retention signal and contributes to intracellular sequestration of MHC class I molecules [PDF]

, 2013
The human adenovirus E3/19K-protein is a type-I transmembrane glycoprotein of the endoplasmic reticulum (ER) that abrogates cell-surface transport of MHC class-I (MHC-I) and MICA/B-molecules.

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+

HLA class II alleles and haplotypes associated with susceptibility to type 1 diabetes and to type 1 diabetes with concomitant autoimmune diseases: a cross-sectional study from Eastern Croatia

Frontiers in Endocrinology
BackgroundType 1 diabetes mellitus (T1D) is an autoimmune disease with a strong genetic predisposition, largely conferred by human leukocyte antigen (HLA) class II genes. Patients with T1D frequently develop additional autoimmune diseases (AIDs). However,

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.
