Identifying the role of NLRP3 inflammasome in stroke progression and outcome before recanalization

Bellut et al. show that the NLRP3 inflammasome drives hyperacute inflammation and infarct progression during large vessel occlusion in stroke. Pharmacological inhibition reduces infarct growth in mice. NLRP3-positive cells in human pial blood before thrombectomy correlate with clinical outcome and highlight a potential therapeutic target prior to recanalization.
