Inflammasomes are multimeric complexes that facilitate caspase‐1‐mediated processing of the pro‐inflammatory cytokines IL‐1β and IL‐18. Clinical hypertension is associated with renal inflammation and elevated circulating levels of IL‐1β and IL‐18. Therefore, we investigated whether hypertension in mice is associated with increased expression and/or activation of the inflammasome in the kidney, and if inhibition of inflammasome activity reduces BP, markers of renal inflammation and fibrosis.

Wild‐type and inflammasome‐deficient ASC^−/− mice were uninephrectomized and received deoxycorticosterone acetate and saline to drink (1K/DOCA/salt). Control mice were uninephrectomized but received a placebo pellet and water. BP was measured by tail cuff; renal expression of inflammasome subunits and inflammatory markers was measured by real‐time PCR …
