Neuronal Injury after Ischemic Stroke: Mechanisms of Crosstalk Involving Necroptosis.

Ischemic stroke is a leading cause of disability and death worldwide, largely due to its increasing incidence associated with an aging population. This condition results from arterial obstruction, significantly affecting patients' quality of life and imposing a substantial economic burden on healthcare systems. While current treatments primarily focus on the rapid restoration of blood flow through thrombolytic therapy or surgical interventions, a limited understanding of neuronal injury mechanisms hampers the development of more effective treatments.This article explores the interplay among various cell death pathways-necroptosis, apoptosis, autophagy, ferroptosis, and pyroptosis-in the context of ischemic stroke to identify novel therapeutic targets. Each mode of cell death displays unique characteristics and roles post-stroke, and the activation of these pathways may vary across different animal models, complicating the translation of therapeutic strategies to clinical settings. Notably, the interaction between apoptosis and necroptosis is highlighted; inhibiting apoptosis might heighten the risk of necroptosis. Therefore, a balanced regulation of these pathways could promote enhanced neuronal survival.Additionally, we introduce PANoptosis, a form of cell death that encompasses pyroptosis, apoptosis, and necroptosis, emphasizing the complexity and potential therapeutic implications of these interactions. In summary, understanding the relationships among these cell death mechanisms in ischemic stroke is vital for developing new neuroprotective agents. Future research should aim for combinatorial interventions targeting multiple pathways to optimize treatment strategies and improve patient outcomes.
