Act as an effective inflammasome inducer soon after their injection into mice. We injected aPNMs after priming with LPS (five ) for 24 hours. Immediately after aPNMs have been subcutaneously injected, lymph nodes have been collected from the immunized mice and made use of for ex vivo analysis of IL-1. As shown in Figure 4C, the secreted concentration of IL-1 in wild-type mice immunized with aPNMs elevated as much as 6 hours following injection. In addition, there was a big distinction betweenFigure three Impact of inflammasome inhibitors.
