Ischemic neuronal cells

Ischemic neuronal cells are neurons that have been compromised by a lack of sufficient blood flow, leading to oxygen and glucose deprivation. This ischemic insult initiates a rapid failure of adenosine triphosphate (ATP) production, causing the breakdown of ion pumps and subsequent membrane depolarization. This state leads to the massive release of excitatory neurotransmitters like glutamate, triggering calcium overload and downstream cascades of oxidative stress, mitochondrial dysfunction, and eventually cell death via necrosis or apoptosis [6], [7]. While "ischemic neuronal cells" describes a physiological state rather than a single molecular target, they are the primary focus of neuroprotective and thrombolytic therapies aimed at salvaging brain tissue in the penumbra during acute stroke [4], [10]. Pharmacological interventions typically target specific molecular pathways within these cells, such as NMDA receptors, sodium channels, or radical scavenging systems, to mitigate the progression of damage [3], [5].
