a Representative Western blot analysis of endometrial Nalp-3 inflammasome expression. Endometrial lysates from RPL (n = 10) showed significantly higher expression of Nalp-3 compared to controls (n = 10) (O.D optical density). Histograms show average ± SD of three independent experiments. b, c Endometrial Nalp-3 inflammasome activation assessed by ELISA. Significantly higher levels of endometrial caspase-1 (b) and Il-1β (c) were observed in RPL patients (n = 35) compared to controls (n = 20). Histograms show average ± SD of three independent experiments. CTR: controls. Statistical significance versus CTR: *P < 0.05; **P < 0.01; ***P < 0.0001. CTR: controls
