Serum proteomic networks associate with pre-clinical rheumatoid arthritis autoantibodies and longitudinal outcomes

Frontiers in Immunology, 2022
ObjectivesThe development of autoantibody directed towards citrullinated proteins (ACPA) are predictive of RA in at-risk individuals. The biological events that underpin loss of immune tolerance and progression into inflammatory arthritis are not known ...

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 ...

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 ...

Upregulation of interferon-γ response genes in monocytes and T cells identified by single-cell transcriptomics in patients with anti-citrullinated peptide antibody-positive early rheumatoid arthritis

Frontiers in Immunology
IntroductionOur aim was to investigate the insufficiently understood differences in the immune system between anti-citrullinated peptide antibody (ACPA)-positive (ACPA+) and ACPA-negative (ACPA-) early rheumatoid arthritis (eRA) patients.MethodsWe ...

Differential ACPA Binding to Nuclear Antigens Reveals a PAD-Independent Pathway and a Distinct Subset of Acetylation Cross-Reactive Autoantibodies in Rheumatoid Arthritis

Frontiers in Immunology, 2019
Rheumatoid arthritis (RA) associated anti-citrullinated protein autoantibodies (ACPA) target a wide range of modified proteins. Citrullination occurs during physiological processes such as apoptosis, yet little is known about the interaction of ACPA with

Light chain skewing in autoantibodies and B-cell receptors of the citrullinated antigen-binding B-cell response in rheumatoid arthritis.

PLoS ONE, 2021
Rheumatoid arthritis (RA) is a chronic autoimmune disease affecting 1% of the world population. RA is associated with the presence of autoantibodies, of which anti-citrullinated protein antibodies (ACPA) are most prominent.

Prevalence of anti-citrullinated protein antibodies (ACPA) in patients with diffuse large B-cell lymphoma (DLBCL): a case-control study. [PDF]

PLoS ONE, 2014
BACKGROUND: Antibodies against citrullinated proteins (ACPA) have been recognised as the most specific serum marker for rheumatoid arthritis. However, serum autoantibodies such as anti-nuclear antibodies have also been detected in the sera of different ...

Evaluation of the immune feature of ACPA-negative rheumatoid arthritis and the clinical value of matrix metalloproteinase-3

Frontiers in Immunology, 2022
Anti-citrullinated protein antibodies (ACPAs) are highly specific for the diagnosis of rheumatoid arthritis (RA). However, about one-third of RA patients are negative for ACPAs, which presents a challenge to the early diagnosis of RA. The purpose of this

Patient burden and joint inflammation during development of RA from arthralgia:is it similar in ACPA-positive and ACPA-negative disease? [PDF]

Objectives: ACPA-positive and ACPA-negative RA differ in underlying risk factors but have a similar clinical presentation at RA diagnosis. It is unknown what the ACPA-associated differences or similarities are during the symptomatic at-risk stage of RA ...
