Concentrations of IL-1β, sIL-1RI, sIL-1RII, and IL-1Ra in plasma of patients with AD. Levels of IL-1β, sIL-1RI, sIL-1RII, and IL-1Ra were quantified by ELISA in plasma. Results are depicted as median [interquartile ranges]. Significance was calculated with the nonparametric Mann-Whitney U test. Values below the lower limit of quantification were set to the lower limit of quantification (IL-1RI: 60 pg/mL, IL-1RII: 250 pg/mL, IL-1Ra: 115 pg/mL). *P < .05. AD indicates Alzheimer disease; IL-1Ra, interleukin 1 receptor antagonist; IL-1RI, interleukin 1 receptor subtype I; IL-1RII indicates interleukin 1 receptor subtype II; IL-1RII, interleukin 1 receptor subtype II; IL-1Ra, interleukin 1 receptor antagonist; SC, symptomatic controls; sIL-1RI, soluble interleukin 1 receptor subtype I; sIL-1RII, soluble interleukin 1 receptor subtype II.
