Abstract
Inflammasomes are multimeric complexes that can sense pathogens and danger signals in the environment. Upon detection of stimuli, caspase-1 is recruited to the inflammasome complex that cleaves and activates pro-inflammatory cytokines, thus initiating a cascade of inflammatory events. While inflammasomes form a crucial component of the host response to pathogens and danger molecules, their unchecked activation can result in the development of autoimmune diseases, metabolic disorders, and pathological outcomes. This chapter describes some assays to detect the measurable outcomes of inflammasome formation and activation. The protocol describes the methods to study the inflammasome pathway using an in vitro assay in primary macrophages. It can be applied to studies investigating the pathway mechanisms and potential therapeutics in the form of inhibitors or activators.
