IL1R1 and epilepsy: Addition of intranasal IL-1β increased seizures following KA at p70–73, associated with hippocampal cell loss in CA3 regionHippocampal IL-1β levels only in rats that developed late-onset seizuresExogenous IL-1β exacerbates FS, while IL-1R–deficient mice show resistance to FSmRNA levels of IL-1R correlates with epilepsy-predictive MRI signal changes
