Figure 5From: Local administration of glucocorticoids decreases synovial citrullination in rheumatoid arthritisDexamethasone (DXM) decreases the expression of citrullinated proteins and PAD4 expression in a rheumatoid arthritis (RA) synovial explant. Brown diaminobenzidine immunoperoxidase staining shows citrullinated proteins as detected with F95 antibody, PAD2 as detected with ROI001 antibody, and PAD4 as detected with SN823 antibody.
