Exploratory experiment designed to discover new patterns targeting histone H3 in in vitro protein degradation assay. Primary outcome: protection of carH3 from neutrophil elastase degradation by anti-CarP antibodies
This experiment evaluated the degradation kinetics of carbamylated histone H3 (carH3) by neutrophil elastase and tested whether anti-carbamylated protein (anti-CarP) IgG antibodies from rheumatoid arthritis patients could protect carH3 from proteolytic degradation. The study examined how antibody binding affects the stability of carbamylated proteins, which has important implications for autoantigen persistence in inflamed joints. The experiment involved incubating carH3 with neutrophil elastase in the presence or absence of patient-derived anti-CarP antibodies and measuring the remaining intact protein over time.
