Web5 mei 2016 · Inflammasomes are large multimolecular complexes best known for their ability to control activation of the proteolytic enzyme caspase-1 (Martinon et al., 2002). Caspase-1 in turn regulates the proteolytic maturation of Interleukin-1β and IL-18, as well as a rapid, noxious, inflammatory form of cell death termed pyroptosis (Rathinam et al., 2012a). WebThe NLRP3 inflammasome is characterized as a cytosolic complex, which belongs to the nucleotide-binding and oligomerization domain-like receptor (NLR) family, as described in Chapter 7. This inflammasome complex comprises NLRP3 protein, ASC (apoptosis-associated speck-like protein containing a caspase recruitment domain), and procaspase 1.
