Figure Lengend Snippet: Fig. 6 Effect of autophagy on CS-mediated NLRP3 Inflammasome inhibition in N. gonorrhoeae-infected macrophages. In panel A, J774A.1 macrophages were pre-incubated with CS or a vehicle in the presence or absence of 5 mM 3-MA for 0.5 h before N. gonorrhoeae infection, followed by an additional 24- hour incubation period. Levels of IL-1β in the supernatants were measured through ELISA. In panel B, wild-type or LC3-knockdown J774A.1 macrophages were incubated with 100 nM rapamycin or a vehicle for 4 h, and the levels of LC3 in the cell lysates were assessed via Western blotting. In panels C-E, wild- type or LC3-knockdown J774A.1 macrophages were pre-incubated with either CS or a control vehicle for 0.5 h before N. gonorrhoeae infection, followed by an additional 24-hour incubation period. The concentrations of IL-1β (C) and IL-6 (E) in the supernatants were measured through ELISA, while the levels of caspase-1 in the supernatants were assessed through Western blotting (D). The ELISA data are presented as the mean ± SD of three independent experiments. The presented Western blotting images represent individual experiments. Statistical significance is indicated as ***p < 0.001 as indicated
