Fig. 5. Cellular activity assays for NLRP3 mutants targeting the AAA+ ATPase fold.

Fig. 5

a Increasing amounts of different NLRP3 variants targeting the AAA+ ATPase fold were transiently over-expressed in HeLa cells stably over-expressing ASC-mTurquoise. ASC specks and nuclei were quantified using microscopy, and the ratio ASC speck/nuclei was plotted as a measure of inflammasome activation. Bars represent mean and SD of 5 independent experiments. b Dose response curves for the active NLRP3 mutants described in a. The half maximal effective concentration (EC50) was calculated for each of the NLRP3 variants. Data points of 5 independent experiments are shown. c, d NLRP3-deficient immortalized macrophages were reconstituted with wildtype NLRP3-mCitrine or indicated variants. c TNF-α and d IL-1β secretion of LPS primed immortalized macrophages stimulated with nigericin in the presence or absence of CRID3. Means ±SEM of pooled data from 3 independent experiments are presented.
