Supplementary Material

The supplementary materials include three figures. In Supplementary Figure 1, western blot results are presented to demonstrate detection of processed, but not unprocessed, IL-1β in our macrophage and bone marrow cell NLRP3 inflammasome stimulation experiments. Furthermore, these data corroborate the ELISA results presented throughout our manuscript by showing alterations in myeloid cell IL-1β production evoked by C5a. Supplementary Figure 2 shows that C5a only modestly regulates NLRP3 inflammasome activity in peritoneal neutrophils. Supplementary Figure 3 presents the data shown in Figure 4 as absolute amounts of IL-1β protein released as opposed to the percent of IL-1β protein released relative to positive control samples.
