The NLR family, pyrin domain-containing 3 (NLRP3) inflammasome is essential for the innate immune response to danger signals. Importantly, the NLRP3 inflammasome responds to structurally and functionally dissimilar stimuli. It is currently unknown how the NLRP3 inflammasome responds to such diverse triggers. This dissertation investigates the role of ion flux in regulating the NLRP3 inflammasome. Project 1 explores the relationship between potassium efflux and Syk tyrosine kinase. The results reveal that Syk activity is upstream of mitochondrial oxidative signaling and is crucial for inflammasome assembly, pro-inflammatory cytokine processing, and caspase-1-dependent pyroptotic cell death. Dynamic potassium imaging and molecular analysis revealed …
