Interferon Regulatory Factor-Inducible Reporter Monocytes

THP1-Lucia™ ISG cells were derived from the human monocytic cell line THP-1, which represents a model of choice to study the activation and signaling of CDSs.

Indeed, THP-1 cells have been shown to express all the CDSs identified so far [1-3], with the exception of DAI [4].

THP1-Lucia™ ISG cells express the secreted luciferase (Lucia) reporter gene under the control of an IRF-inducible promoter. This composite promoter is comprised of five IFN-stimulated response elements (ISRE) fused to an ISG54 minimal promoter, which is unresponsive to activators of the NF-kB or AP-1 pathways.

As a result, THP1-Lucia™ ISG cells allow the monitoring of the IRF pathway by determining the activity of Lucia luciferase. The levels of IRF-induced Lucia luciferase in the cell culture supernatant are readily assessed with QUANTI-Luc™ 4 Lucia/Gaussia, a Lucia and Gaussia luciferase detection reagent.

THP1-Lucia™ ISG cells are resistant to Zeocin®.

THP1-Lucia™ ISG cells are highly responsive to STING and CDS ligands, such as transfected double-stranded nucleic acids.

Cells were transfected with CDS ligands (1 µg/ml of HSV-60, HSV-60c, VACV-70, VACV-70c, ISD, ISD Control or 0.3 µg/ml pCpGfree-giant, poly(dA:dT), poly(dA), poly(dG:dC) using LyoVec™ or directly stimulated with 10 µg/ml c-di-AMP or c-di-GMP.
After 24h incubation, the levels of IRF-induced Lucia luciferase were determined using QUANTI-Luc™.
