WebCitrullination, the post-translational modification of arginines to citrullines, is catalyzed by the peptidylarginine deiminases (PADs). In activated neutrophils, PAD4 citrullinates histones enhancing chromatin unraveling and NET formation [ 7, 8 ], and PAD4 is required for NETosis in response to a variety of stimuli [ 7, 9, 10, 11, 12 ]. WebCitrullinated peptides in autoimmune diseases have been extensively studied in the last two decades.
