Arthritis &Rheumatology, Accepted Article.Background CD4 T cells specific for citrullinated (cit)‐peptides are key players in RA immunopathogenesis. Characterising 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 generation of RA treatments.

Anti-citrullinated Protein Antibody Generation, Pathogenesis, Clinical Application, and Prospects
Frontiers in Medicine, 2022 Anti-citrullinated protein antibodies (ACPAs) are autoantibodies commonly observed in patients with rheumatoid arthritis (RA). Currently, most of the mechanisms of ACPA formation and bone destruction are well-understood, however, some unknown mechanisms ...

Citrullination – small change with a great consequence [PDF]
, 2013 Citrullination is one of the possible post-translational modifications of proteins. It is based on a conversion of L-arginine residue (L-Arg) to L-citrulline residue (L-Cit). The reaction is catalyzed by peptidylarginine deiminases (PAD). The change of L-

Arthritis &Rheumatology, Accepted Article.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.

BMEMat, EarlyView.The effects of NETs on regeneration of various diabetic tissues, and strategies targeting NETs for diabetes tissue regeneration. In the diabetic environment, NETs undergo complex metabolic and immune reprogramming, leading to dynamic changes in antibacterial and proinflammatory functions, and affecting regeneration of multiple systemic tissues.

PAD4 takes charge:Detection and quantification of protein citrullination [PDF]
Citrullination comprises the enzymatic modification of peptidylarginine to peptidylcitrulline by peptidyl arginine deiminase (PAD) enzymes. The role of citrullination in innate immunity has particularly sparked scientific interest after the finding that ...

Reactive oxygen species inhibit catalytic activity of peptidylarginine deiminase
Journal of Enzyme Inhibition and Medicinal Chemistry, 2017 Protein citrullination catalysed by peptidylarginine deiminase (PAD) may play an important pathogenic role in several chronic inflammatory diseases and malignancies. PAD2, PAD4, and citrullinated proteins are found in the synovium of rheumatoid arthritis

Cancer Nexus, EarlyView.ABSTRACT Inflammatory bowel disease (IBD), primarily Crohn's disease and ulcerative colitis, is a chronic relapsing inflammatory disorder of the gastrointestinal tract and an important risk factor for IBD‐associated cancer. Increasing evidence suggests that gut microbiota dysbiosis, epithelial barrier dysfunction, and immune microenvironment remodeling

Histone Citrullination Mediates a Protective Role in Endothelium and Modulates Inflammation
Cells, 2022 NETosis is a key host immune process against a pathogenic infection during innate immune activation, consisting of a neutrophil “explosion” and, consequently, NET formation, containing mainly DNA, histones, and other nuclear proteins.
