PD-1 / NFAT Reporter – Jurkat Cell Line
The PD-1 reporter cell line is a T cell line expressing luciferase under the control of NFAT response elements. The level of the luciferase activity measured with the One-Step luciferase detection system (BPS Bioscience) corresponds to the T cell activation in response to the TCR activator from the target cell.
To escape, the target cell may present PD-L1 or PD-L2 to PD-1. Indeed, the interaction inhibits the T cell activation. It leads to decrease in luciferase activity. [Read more…]
