Citrullination and carbamylation in the pathophysiology of rheumatoid arthritits

Frontiers in Immunology, 2015
The discovery that citrullination was crucial for the recognition of antigens by the most disease-specific class of autoantibodies in rheumatoid arthritis had a huge impact on studies aimed at understanding autoimmunity in this disease.

Joint inflammation related citrullination of functional arginines in extracellular proteins

Scientific Reports, 2017
We report the extent, specific sites and structural requirements of joint inflammation related citrullination in extracellular proteins. A total of 40 synovial fluid samples derived from chronically inflamed human joints were analysed by heparin-agarose ...

Belimumab Decreases Autophagy and Citrullination in Peripheral Blood Mononuclear Cells from Patients with Systemic Lupus Erythematosus

Cells, 2022
Belimumab (BLM) is a B lymphocyte stimulator (BLyS) inhibitor approved for the treatment of systemic lupus erythematosus (SLE). Autophagy is a cell survival mechanism involved in the pathogenesis of SLE.

Upregulation of citrullination pathway: From Autoimmune to Idiopathic Lung Fibrosis

Respiratory Research, 2017
Background Increased protein citrullination and peptidylarginine deiminases (PADIs), which catalyze the citrullination process, are central in Rheumatoid arthritis pathogenesis and probably involved in the initial steps towards autoimmunity ...

Determination of Citrulline in Plasma

Clinical Chemistry, 1960
Abstract The Archibald method for the determination of plasma citrulline has been modified to eliminate the dialysis step in order to separate citrulline from plasma proteins. Instead these are precipitated with picric acid and the picrate ion removed by passage through an anion exchange column.

Anti‐Carbamylated Protein Antibodies Stabilize Carbamylated Histone H3 to Promote Synovial Activation and Neutrophil Extracellular Trap‐Mediated Bone Loss in Rheumatoid Arthritis

Arthritis &Rheumatology, EarlyView.
Objective Carbamylation, a nonenzymatic post‐translational modification, contributes to rheumatoid arthritis (RA) pathogenesis. Anti‐carbamylated protein antibodies (anti‐CarP) occur in around 50% of patients with RA and associate with greater joint damage. Neutrophil extracellular traps (NETs) are a major source of carbamylated autoantigens. We sought

Exacerbation of symptomatic arthritis by cigarette smoke in experimental arthritis.

PLoS ONE, 2020
IntroductionEpidemiologically, cigarette smoking is a well-known risk factor for the pathogenesis of rheumatoid arthritis (RA). However, there has been few plausible explanations why cigarette smoking aggravated RA.

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 ...

Citrullination modulation stabilizes HIF-1α to promote tumour progression

Nature Communications
Citrullination plays an essential role in various physiological or pathological processes, however, whether citrullination is involved in regulating tumour progression and the potential therapeutic significance have not been well explored.
