Analysis of Activity and Expression of the NLRP3, AIM2, and NLRC4 Inflammasome in Whole Blood

Methods Mol Biol. 2022:2459:105-116. doi: 10.1007/978-1-0716-2144-8_11.

Abstract

Pro-inflammatory caspase-1 is a key player in innate immunity. Following activation in heterogenic protein complexes called the inflammasome , caspase-1 processes IL-1β and IL-18 to their mature forms and triggers pyroptosis. Here, we describe a small-volume whole blood assay facilitating the measurement of caspase-1 activity and inflammasome-related gene expression following specific stimulation of either the NLRP3, NLRC4, or AIM2 inflammasome .

Keywords: AIM2; Caspase-1; Inflammasome; MCC950; NLRC4; NLRP3; Whole blood assay.
