Neutrophil dynamics and inflammaging in acute ischemic stroke: A transcriptomic review

Area of Science:

• Neurology
• Immunology
• Gerontology

Background:

• Stroke is a leading cause of death and disability globally.
• Current acute treatment (recanalization) often fails to restore functional independence.
• Aging is a major risk factor for stroke and poorer outcomes.

Purpose of the Study:

• To review the role of neutrophil activation in futile recanalization after stroke.
• To discuss age-related molecular and cellular changes contributing to stroke vulnerability.
• To explore how gene expression patterns in neutrophils and aging impact stroke treatment response.

Main Methods:

• Literature review of studies on stroke, immune cells (neutrophils), and aging.
• Analysis of differential gene expression in relation to stroke injury and age.
• Synthesis of current understanding of molecular and cellular interactions.

Main Results:

• Neutrophil activation may cause microcirculatory failure and ineffective recanalization.
• Ischemic stroke exhibits complex age-related disease characteristics.
• Aging is associated with increased mortality and susceptibility to cerebrovascular diseases.

Conclusions:

• Understanding neutrophil function and age-related changes is critical for developing effective stroke treatments.
• Targeting age-dependent vulnerability could improve clinical outcomes.
• Neutrophil gene expression patterns offer insights into poor treatment responses in stroke.
