IL1B and Alzheimer disease: In an oxazolone (OXA)-induced AD mouse model, we found that basophils acted as key initiators of inflammation by producing IL-1β in the lesion, and that basophil depletion, genetic ablation of Nlrp3 or Il1b, or basophil-specific genetic ablation of Nlrp3 ameliorated ear swelling and neutrophil infiltration.
