Topic | The NLRP3 inflammasome is a multi-protein complex driving inflammation upon exogenous and endogenous (sterile) insults during infection, tissue damage or cellular stress and its assembly has been considered a key process in initiating inflammation. We have identified the well-known signaling molecule Bruton’s Tyrosine Kinase (BTK) as an unexpected but prominent regulator of NLRP3 inflammasome activity in both mice and humans. The discovery of BTK as an NLRP3 regulator offers the unique opportunity to target the NLRP3 inflammasome at the level of a well-known pharmacological target, BTK, via efficacious and well-tolerated FDA-approved inhibitors, e.g. ibrutinib (PCI-32765). For doing so, the mechanistic molecular and the cellular role of BTK in inflammasome activation needs to be more comprehensively studied, which is the goal of this present project. Our vision is to elucidate the molecular workings of the BTK-NLRP3 inflammasome to a level that will allow for safely harnessing the considerable translational potential of BTK as a targetable NLRP3 regulator.
