Real-time monitoring of ASC-dependent inflammasomes 

THP1-ASC-GFP cells are inflammasome reporter cells that allow the monitoring of ASC (apoptosis-associated speck-like protein with a CARD)-dependent inflammasome formation using fluorescence microscopy.

These cells are derived from the THP-1 human monocytic cell line and stably express a gene encoding an ASC::GFP fusion protein for which expression is driven by an NF-κB-inducible promoter. Hence, in resting cells, no GFP signal is detected. Upon the first step of inflammasome activation (‘priming”), NF-kB-dependent ASC::GFP expression is induced and can be observed throughout the cytoplasm. Following the second step of inflammasome activation, ASC::GFP polymerizes to form a macromolecular, micrometer-sized complex. The number of ASC::GFP positive cells and localization of fluorescent ASC specks can be determined by using time-lapse confocal or high-resolution fluorescence microscopy. In most cells only one speck forms upon inflammasome activation [1,2].

THP1-ASC-GFP cells are resistant to Zeocin™.
