Myeloperoxidase (MPO) antibodies are autoantibodies targeting MPO, a heme-containing enzyme found in neutrophils and monocytes. MPO plays a key role in innate immunity by generating reactive oxygen species to destroy pathogens. These antibodies are primarily associated with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV), including granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), and eosinophilic granulomatosis with polyangiitis (EGPA). Unlike proteinase 3 (PR3) antibodies linked to cytoplasmic-ANCA (c-ANCA) patterns, MPO antibodies typically produce a perinuclear-ANCA (p-ANCA) staining pattern in immunofluorescence assays.
Clinically, MPO antibodies serve as diagnostic biomarkers for small-vessel vasculitis and are implicated in disease pathogenesis through neutrophil activation and vascular endothelial damage. Their presence correlates with renal involvement, such as pauci-immune necrotizing glomerulonephritis. Detection methods include ELISA, chemiluminescence, and indirect immunofluorescence, often used in combination for improved diagnostic accuracy. While elevated titers may reflect disease activity, they are not universally reliable for monitoring treatment response. Research continues to explore their role in disease mechanisms, prognosis, and potential therapeutic targets. MPO antibodies also occasionally occur in other autoimmune conditions, infections, or drug-induced reactions, necessitating clinical correlation for interpretation.
