text_1: Citrullinated proteins externalized in neutrophil extracellular traps act indirectly to disrupt the inflammatory cycle.
text_2: Bands reactive with RA sera were excised from gels, digested with trypsin and subjected to matrix-assisted laser desorption/ionisation time of flight (MALDI-TOF) analysis, before and after derivatisation to detect citrullinated peptides.
