IL-33 Sensor Cells

HEK-Blue™ IL-33 cells are designed to detect bioactive IL-33 by monitoring the activation of the NF-κB and AP-1 pathways. They were generated by stable transfection of HEK293-derived cells with the human IL1RL1 gene. In addition, the TNF-α and the IL-1β responses have been blocked. Therefore, HEK-Blue™ IL-33 cells respond specifically to IL-33. These cells express an NF-κB/AP-1- inducible SEAP reporter gene.

Binding of human IL-33 to the heterodimeric IL-33 receptor on the surface of these cells triggers a signaling cascade leading to the activation NF-κB and the subsequent production of SEAP. Levels of SEAP in the supernatant can be easily determined with QUANTI-Blue™.


EK-Blue™ IL-33/IL-1β cells were incubated with human IL-33, IL-1β, IL-18 and TNF-α. After a 24h incubation, SEAP activity was assessed using QUANTI-Blue™ and reading optical density (O.D.) at 655 nm.

Description

HEK-Blue IL-33/IL-1beta cells pathway

Interleukin-33 (IL-33) is a member of the IL-1 family, a group of cytokines that play important roles in host defense, immune regulation and inflammation. IL-33 mediates its biological effects through IL1RL1 (also known as ST2), a receptor expressed on Th2 and mast cells.

IL-33 and IL1RL1 form a complex with IL-1R accessory protein (IL-1RAcP), a signaling receptor subunit that is also a member of the IL-1R complex. IL-33 signaling leads to the activation of NF-kB and MAP kinases, and the production of Th2-associated cytokines.
