Inflammasome targeting for periodontitis prevention is sex dependent.

ABSTRACT: Inflammasome initiates inflammation via the maturation of interleukin-1 beta (IL-1β). Periodontitis is a prevalent, male-biased disease characterized by inflammation-driven bone loss, yet the mechanism(s) of this sex bias is unknown. This study explored whether enhanced inflammasome represents a causal mechanism for this bias. Analyses of three separate human studies (>6,200 samples) show that males have significantly higher IL-1β in the gingival crevicular fluid than females during health and periodontitis. This pattern is experimentally reproduced with different versions of the ligature-induced periodontitis mouse model where males show greater IL-1β secretion than females. The inflammasome drives bone resorption in males but not females as revealed by analyses of inflammasome gene-delet
