Here we highlight the emerging non canonical functions of MPO including its impact on neutrophil longevity activation and trafficking in inflammation its interactions with other immune cells and how these interactions shape disease outcomes
This review scrutinizes the multifaceted roles of MPO in immunity focusing on neutrophil mediated host defense tissue damage repair and autoimmunity We also discuss novel therapeutic approaches to target MPO activity expression or MPO signaling for the treatment of inflammatory and autoimmune diseases

Myeloperoxidase Regulation of Neutrophil Function and Target
We present evidence in support of MPO as a major arm of oxidative killing by neutrophils and propose that the essential contribution of MPO to normal innate host defense is manifest only when exposure to pathogens overwhelms the capacity of other host defense mechanisms

The Role of Neutrophils in the Immune System An Overview
Indeed evolving evidence indicates that MPO can directly modulate the function and fate of neutrophils thereby shaping immunity These actions include MPO orchestration of neutrophil trafficking activation phagocytosis lifespan formation of extracellular traps and MPO triggered autoimmunity
This concerns the role of MPO in neutrophil functions during inactivation and killing of ingested microbes and fungi as well as the potential contribution of released MPO in the modification of proteins in disease progression
Myeloperoxidase MPO is a heme containing peroxidase expressed mainly in neutrophils and to a lesser degree in monocytes In the presence of hydrogen peroxide and halides MPO catalyzes the formation of reactive oxygen intermediates including hypochlorous acid HOCl
Myeloperoxidase Regulation of Neutrophil Function and Target
MPO facilitates neutrophil trafficking into the inflamed site evokes neutrophil activation degranulation and generates survival cues by suppressing constitutive neutrophil apoptosis through non enzymatic actions on CD11b
Multifaceted pro inflammatory and protective functions of the heme protein myeloperoxidase the most abundant protein in neutrophils have extensively been reviewed The focus is directed on non enzymatic functions of this protein

Myeloperoxidase inhibition reduced neutrophil degranulation and neutrophil mediated endothelial cell damage in patients with ANCA associated vasculitis In preclinical crescentic GN delayed myeloperoxidase inhibition suppressed kidney damage without augmenting adaptive immune responses suggesting it might offer a novel adjunctive therapeutic
Dysfunctions in neutrophils and disruptions in neutrophil homeostasis have been implicated in the pathogenesis of numerous diseases including cancer and inflammatory disorders often due to
Among the microbicide proteins is the heme containing enzyme myeloperoxidase MPO the most abundantly expressed protein by human neutrophils MPO utilizes chloride as a co substrate with H sub 2 O sub 2 to generate chlorinating oxidants such as HOCl which have one of the highest cytotoxic potentials to bacteria and living cells 11
