ASC-puncta were visualized using fluorescent microscopy, with DAPI used to stain nuclei. B ) RAW-ASC cells pretreated with vehicle or selected drugs for 16h, followed by washing with PBS and incubation with LPS (1μg/ml) for 2 hours, followed by incubation with Nigericin (5 μM) for 1 hour. Cells were fixed and permeabilized and stained with anti-ASC antibody and Alexa-labeled secondary antibody. ASC-puncta were visualized using fluorescent microscopy, with DAPI used to stain nuclei.

Figure Lengend Snippet: A, B ) Western blot analysis of basal or LPS-induced expression of various inflammasome components in THP-1 ASC-GFP cells pretreated with vehicle or selected drugs for 16h. C, D ) Western blot analysis of basal or LPS-induced expression of various inflammasome components in RAW- ASC cells pretreated with vehicle or selected drugs for 16h. E ) Age-matched (10-week-old) male WTC57BL6J mice fed with chow diet were i.p injected with saline or saquinavir. After 2 hours, mice were primed for inflammasome assembly by an I.P. injection of LPS (5μg/mouse). After 4h of LPS injection, the NLRP3 inflammasome assembly was induced by I.P. injection of ATP (0.5 mL of 30 mM, pH 7.0). The peritoneal cavity was lavaged with 5 mL sterile PBS, and IL-1β levels in peritoneal lavage were determined by ELISA (N = 6, mean ± SD for all groups, ∗∗p < 0.01 by two-tailed t-test). Mouse plasma was used in multiplex analysis to determine levels of F ) TNF-α, G ) IL-1β, H ) IL-17A, I ) IL-33, and J ) IL-15 (N=3, mean ± SD for all groups, ∗p < 0.05 by two-tailed t-test).
