Inflammasome assembly in the chorioamniotic membranes during spontaneous labor at term.

ABSTRACT: Inflammasome activation requires two steps: priming and assembly of the multimeric complex. The second step includes assembly of the sensor molecule and adaptor protein ASC (an apoptosis-associated speck-like protein containing a CARD), which results in ASC speck formation and the recruitment of caspase (CASP)-1. Herein, we investigated whether there is inflammasome assembly in the chorioamniotic membranes and choriodecidual leukocytes from women who underwent spontaneous labor at term. Using in situ proximity ligation assays, ASC/CASP-1 complexes were determined in the chorioamniotic membranes from women who delivered at term without labor or underwent spontaneous labor at term with or without acute histologic chorioamnionitis (n=10-11 each). Also, ASC speck formation was determined by fl
