Abstract:
Stroke is the leading cause of mortality and morbidity worldwide, significantly impacting human welfare and overall health. Myeloperoxidase (MPO), a heme peroxidase secreted by neutrophils, plays a crucial role in the body's defense mechanisms, exhibiting pro-inflammatory and pro-oxidative properties. Additionally, MPO compromises the structural integrity and functional capacity of blood vessels, potentially leading to the formation and dislodgement of atherosclerotic plaques, vascular stenosis, thrombosis, and ultimately contributing to stroke occurrence. Following a stroke, a significant influx of neutrophils infiltrates the cerebral tissue, leading to an excessive release of MPO-derived oxidants and the subsequent promotion of various inflammatory mediators, thereby exacerbating cerebral tissue damage. Numerous studies have consistently demonstrated the pivotal role of MPO in the pathogenesis and progression of stroke, establishing it as a reliable prognostic indicator. Exploring the association between MPO and stroke enhances our understanding of the pathological mechanisms underlying stroke and aids in the development of therapeutic interventions. This review provides a comprehensive analysis of the molecular structure and cellular localization of MPO, elucidating its critical role in mediating vascular injury, the formation of Neutrophil Extracellular Traps (NETs), oxidative stress, neuroinflammation, disruption of the blood-brain barrier (BBB), and neuronal apoptosis during stroke pathogenesis. Additionally, we discuss recent advancements in MPO-targeted drugs and Traditional Chinese Medicine compounds as potential therapeutic strategies for stroke treatment.
