The Infectious Basis of ACPA-Positive Rheumatoid Arthritis

Frontiers in Microbiology, 2017
Rheumatoid arthritis (RA) is associated with HLA-DRB1 shared epitope (HLA-DRB1SE) and anti-citrullinated protein autoantibodies (ACPAs). ACPAs precedes the onset of clinical and subclinical RA.

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.

Reactivity of anti-CCP2-positive sera (n = 15) to citrullinated resin-bound fibrinogen peptides analysed by modified ELISA.

, 2015
Noncitrullinated peptides to each citrullinated peptide were used as controls. Peptides marked by *, indicate citrulline-containing peptides.

The Role of IgM Anti‐acetylated Protein Antibodies and B Cells in the Origin of Antimodified Protein Autoimmunity in Rheumatoid Arthritis

Arthritis &Rheumatology, EarlyView.
Objective Rheumatoid arthritis (RA) is characterized by anti‐modified protein antibodies (AMPAs), including anti‐citrullinated protein antibodies (ACPA), anti‐carbamylated protein antibodies (anti‐CarP), and anti‐acetylated protein antibodies (AAPA). In contrast to other AMPAs, AAPA IgM is found in healthy individuals, raising questions about its role ...

Increased Plasma Microbial tDR‐1 in At‐Risk Individuals Is Associated With Decreased Conversion to Clinical Rheumatoid Arthritis and Reduces an In Vitro Macrophage Type 1 Interferon Response

Arthritis &Rheumatology, EarlyView.
Objective Microbial small RNAs can regulate human genes. Higher plasma concentrations of microbial transfer RNA (tRNA)‐derived RNA‐1 (tDR‐1) were previously associated with lower rheumatoid arthritis (RA) disease activity. This study examined whether tDR‐1 concentrations differ in anticyclic citrullinated peptide‐3 positive (CCP3+) at‐risk individuals (

Neutrophil extracellular traps in inflammatory disorders [PDF]

, 2014
A novel feature of polymorphonuclear granulocyte (PMN) biology is their ability to generate neutrophil extracellular traps (NETs) via a distinct process of cell death termed NETosis.

Anti–Carbamylated Fibrinogen Autoantibodies of IgG and IgA Isotypes Contribute to a Better Prognostic Stratification in Very Early Rheumatoid Arthritis: Data From the French National ESPOIR Cohort

Arthritis &Rheumatology, EarlyView.
Objective The aim of this study was to investigate the prevalence and longitudinal evolution of anti–carbamylated fibrinogen antibodies (ACa‐Fib) of IgG and IgA isotypes in early rheumatoid arthritis (RA) and determine whether these antibodies provide additional diagnostic and prognostic information beyond anti–cyclic citrullinated peptide (anti‐CCP ...

Insights of rheumatoid arthritis risk factors and associations

Journal of Translational Autoimmunity, 2019
Rheumatoid arthritis (RA) is a defective post-translational modification of citrullinated peptides which cause synovial inflammation in joints. The present review elaborates the basic mechanisms of RA and the root causes of molecular mechanisms.
