1

Ischemic stroke is a leading cause of death and disability, with over 30% of large vessel occlusion patients developing severe long-term disability.
2

Interleukin-1β (IL-1β) plays a crucial role in postischemic inflammation and is produced by monocytes and microglia in response to cell death.
3

Neutrophil extracellular traps (NETs) formed by activated neutrophils contribute to ischemic injury through thrombus formation and microcirculatory impairment.
4

The study utilized liquid biopsies to analyze ischemic blood samples, revealing hyperacute immune responses in the cerebral circulation after stroke.
5

Targeted inhibition of the IL-1β-driven immune cascade may prevent thromboinflammation and reduce neurotoxic inflammation in acute stroke patients.
