Local and systemic levels of IL-1β and IL-6 were significantly attenuated in Casp11
−/− mice following infection with Toxoplasma gondii. Whole blood, peritoneal lavage fluid (PLF), and brains were collected from wild type, Casp11
−/−, and Asc
−/− mice 15 days after inoculation with Toxoplasma gondii Me49 (a–d). IL-1β and IL-6 levels were determined in (a, b) serum and (c, d) cell-free PLF supernatant by ELISA. (e) IFN-γ levels were also evaluated in the cell-free PLF supernatant. (f, g) Brain samples were weighed and homogenized, and IL-1β and IL-6 levels were determined using the resultant cell-free supernatants. ∗
