Na+/Ca2+ Exchanger Modulation in Cerebral Ischemia
Summary
Cerebral ischaemia arises when blood flow to the brain is interrupted, triggering a cascade of events that culminate in energy failure, ionic imbalance and neuronal death. Central to this process is intracellular accumulation of calcium, which activates degradative enzymes and precipitates cell injury. The Na+/Ca2+ exchanger (NCX) family, comprising plasma‐membrane antiporters that normally extrude Ca2+ in exchange for Na+, plays a pivotal role in maintaining calcium homeostasis. Under ischaemic conditions, however, elevated intracellular Na+ can reverse the exchanger, exacerbating Ca2+ overload. Distinct NCX isoforms (NCX1, NCX2 and NCX3) and K+-dependent counterparts (NCKXs) are differentially expressed in neuronal and glial populations and can be targeted to shift exchanger activity towards calcium efflux. Modulation of NCX function, either by genetic upregulation, post‐transcriptional control or pharmacological intervention, has emerged as a promising strategy to limit calcium‐mediated injury during both the acute phase of ischaemia and the reperfusion period that follows restoration of blood flow. Understanding the molecular regulators of NCX expression and activity is thus essential for the design of neuroprotective approaches capable of attenuating infarct size and improving functional recovery after stroke.

Na+/Ca2+ Exchanger Modulation in Cerebral Ischemia publication trend
The graph below shows the total number of articles in na+/ca2+ exchanger modulation in cerebral ischemia across all publications each year (not limited to Nature Index journals).
Technical terms
Na+/Ca2+ exchanger: A membrane protein that regulates intracellular calcium by exchanging three sodium ions for one calcium ion.
Ischaemic preconditioning: A protective strategy in which brief, sub‐lethal ischaemic episodes render tissue more resistant to subsequent severe ischaemia.
Reperfusion injury: Tissue damage that occurs upon restoration of blood flow after an ischaemic event, often linked to oxidative stress and calcium dysregulation.
MicroRNA: Small non-coding RNA molecules that post-transcriptionally regulate gene expression by binding target mRNAs.
Blood–brain barrier: A specialised endothelial interface that restricts entry of circulating substances into the central nervous system.
Infarct volume: The region of irreversibly damaged brain tissue following ischaemic insult.
