To further determine if miR-233 dampens LCWE-induced KD vasculitis in WT mice by decreasing NLRP3 inflammasome activation and subsequent IL-1β production, we next quantified the circulating levels of IL-1β in LCWE-injected WT and mir-223−/y mice 1 week after LCWE injection. This evidence concerns the gene NLRP3 and vasculitis.
