WebSep 1, 2024 · Anti-citrullinated protein antibodies (ACPAs) are well-established biomarkers for rheumatoid arthritis (RA), which are believed to arise in the context of aberrant peptidyl arginine deiminase (PAD) citrullination. Of the five human isoforms, PAD2 and PAD4 are considered most likely to be involved in disease pathogenesis.
WebAbstract Objective: To explore the relevance of citrullinated proteins and anti-citrullinated protein antibodies (ACPA) via protein arginine deiminase (PAD) inhibition in peptide glucose-6-phosphate isomerase-induced arthritis (pGIA). Methods: Cl-amidine, a PAD inhibitor, was injected into pGIA.
