Pro-inflammatory cytokine levels are reduced in the serum of aging Asc−/− mice. Serum IL-6 (A) concentration measured in 2, 6, 12, and 18-month-old WT and Asc−/− mice. Circulating levels of TNF-α (B) and IL-18 (C) determined in 2, 6, 12, and 18-month-old WT, Asc−/−, and Nlrp3−/− mice. n = 4–6 per cohort. ND, Not Determined. Data are presented as mean ± SEM. For each age group, comparisons were made with WT using Student's t-test (A,C) or Mann-Whitney test (A–C) (*p < 0.05, ****p < 0.0001).
