ATP-induced Cell Death Mechanism

Abstract

"ATP-induced cell death" is a novel form of cellular demise identified since 1991, typically characterized by a substantial accumulation of adenosine triphosphate (ATP) and the activation of ATP membrane receptors during the cell death process. The perturbation of ATP homeostasis is intricately linked to mitochondrial function. In recent years, ATP-induced cell death (AICD) has emerged as a discernible pattern of cell demise attributed to heightened levels of extracellular ATP (eATP). This phenomenon is intimately associated with the pathophysiological mechanisms underpinning a plethora of maladies, including malignancies, neurodegenerative disorders, ischemia-reperfusion injury, renal impairment, and hematological conditions. The strategic modulation of ATP-induced cell death to mitigate the onset and progression of these related diseases has garnered significant attention and stands as a focal point in etiological research and therapeutic interventions. Nevertheless, the functional alterations and precise molecular mechanisms governing ATP-induced cell death demand further comprehensive exploration. This paper comprehensively synthesizes the most recent advancements in the understanding of ATP-induced cell death mechanisms, with the overarching objective of serving as a reference for a deeper comprehension of its pathogenesis and the proposition of novel therapeutic targets for the management of associated diseases.
